Yours comes from seeds, and it is generally not easy to bear fruit. Just use grafted seedlings, and it will bear fruit in three years.

You can't plant it directly in a flowerpot, but on the ground.

Your seeds are called seedlings. Generally, they can't bear fruit, and they are too small to eat.

You can only enjoy it as a green plant, hehe

Question 2: Why didn't the jujube I planted turn out to be three years old, which is worth considering! -For merchants who manage seedlings, it can only be jujube seedlings cultivated by "high-level layering" with fast seedling growth and high survival rate! Judging from the management methods of jujube seedling merchants, this kind of jujube seedling is only a "advanced layering" jujube seedling cultivated for about one year. After you buy it, it will take at least 2-3 years to blossom and bear fruit under the correct cultivation management! As for how to make this jujube seedling bear normal fruit, there are also the following points: ① It is advisable to use flowerpots with a diameter of 40-60 cm and plant them in fertile soil with good aggregate structure. The soil in the basin is large, loose and breathable, which is conducive to the soil in the basin not being frequently sucked up by jujube trees, and the loose and breathable soil is not easy to be waterlogged and stuffy. (2) It should be planted in a sunny place and receive as much sunlight as possible. Because jujube is a xerophyte that likes sunshine, insufficient sunshine will affect the production of photosynthetic nutrition, which directly leads to thin leaves and thin branches of jujube. ③ Control watering and fertilization of jujube trees. Watering should be "not dry and not watered, but thoroughly watered" in line with the natural sunny and rainy law; And in the growing period, as long as the leaves are dark green and do not turn yellow, there is no need to fertilize them so frequently. Due to excessive water and fertilizer, jujube always shows its young and vigorous branches and leaves and grows wildly. When there is no sunshine, its roots will be flooded and rotten, which makes it look "but how can it not grow ... die ... when it grows leaves, it will flourish ... unlike malnutrition ...". -Because any fruit tree will blossom and bear fruit only when it is "dry and wet, with moderate fertility"! Otherwise, you can only appreciate the leaves ... It's true! ④ Reasonable pruning. It is necessary to cut off the top advantage of crazy long branches, and cut off the dense branches and weak branches that overlap and shade, so that the crown can receive sunlight more evenly and balance the distribution of nutrients on each branch. (5) scramble to cut garlands. In the vigorous growth period of mid-spring or early summer, girdling should be carried out at the bifurcation of each main branch at a distance of 5- 10 cm: bark with a width of about 2 mm can be cut off around (or the meridians of bark can be twisted with iron wires with corresponding thickness). Let it have a fatal sense of crisis (plants also know it), prompting it to produce signals of reproduction (adult trees will almost blossom and bear fruit in the second year). Note: Cut off a circle of bark about 2 mm wide around the wood. After 1- 1.5 months, scars can be formed. If the wire is used for ligation, when it is seen that the bark bulges at both ends are parallel to the wire, the wire can be pulled out to make it naturally heal into a scar. The above is my analysis and opinion, as well as my experience and suggestions on potted fruit trees. I hope you can see the flowers and fruits soon!

Question 3: Can jujube stones grow into jujube trees? Jujube pit is the seed of jujube tree. Under the suitable temperature and humidity environment, the seedlings grown from it can be grafted on various jujube trees.

Seek adoption

Question 4: When is the best time for jujube tree grafting? The advantages of grafting propagation of jujube seedlings are as follows: first, it can maintain the excellent characteristics of scion varieties. This is because scions are branches or buds from excellent adult trees. Genetics is relatively stable, and generally does not mutate after grafting. For example, the famous Zanhuang jujube and Dongzao jujube are all grafted with Zizyphus jujuba. There is little difference in fruit size and content between grafted fruit and root fruit. Second, it can bear fruit early. Because the rootstock has developed root system, it grows vigorously after grafting and its branches are strong. This can turn slow growth into rapid growth. Zaoshu, Tianjin Jinghai Nursery, Shanxi Lizao and Dongzao were grafted on April 20th. 1999. In that year, the height of seedlings reached more than 1.5m, up to nearly 2m, the stem diameter was nearly 2cm, and there were 15~20 secondary branches with a length of 40cm. That year, some trees bore fruit. In 2000, a pear jujube left in the nursery bore fruit, with a yield of 2 kg. Third, it can enhance the resilience of jujube trees. Because the grafting rootstock Ziziphus jujuba has strong drought resistance and barren resistance, it has wide adaptability to soil; If the seedlings are cultivated by root tillers or jujube or jujube seeds grown locally on this anvil. It has completely adapted to the local soil and climate conditions, and this valuable adaptability and stress resistance of this rootstock has had a good impact on grafting jujube trees. Fourth, make full use of Ziziphus jujuba resources. Jujube grows in the mountains and plains of China. Grafting jujube trees is an effective way to speed up the greening of barren hills, wasteland, hills and gully slopes and expand the planting scope of jujube trees. Working people in China have a long history of marrying jujube with jujube. Up to now, hundreds of old jujube trees grafted with jujube are still preserved in Zaolinping, Suide County, Shaanxi Province and Beishuiyu Village, Fuping County, Hebei Province, and have a certain output. After liberation, Shanxi, Shandong, Hebei, Henan, Liaoning, Gansu and other places have done a lot of work in jujube grafting. In recent years, Tianjin has also carried out this work in the mountainous area of Jixian County, and achieved remarkable results.

Grafting method: the time and method of jujube grafting directly affect the survival rate of grafting and the growth of the year. After several years of practice, the editor concluded that the grafting survival rate of jujube trees after spring germination was the highest and the growth was large. The survival rate will decrease if the grafting is too early, and the growth will decrease if the grafting is too late. In Tianjin, April 20th to May 15 is generally suitable. Generally, the survival rate of bud grafting is the highest in July-August growing season.

There are two ways to graft jujube trees, one is branch grafting; The other is bud grafting. According to the editor's research in recent years, when the rootstock and scion are thick, the abdominal incision method should be adopted for grafting, so that even if the operation is simple, the survival rate is high, and there is no need for posts and binding strips after grafting. Subcutaneous grafting should be used when the rootstock is thick and the scion is thin; If the rootstock scions are thin, it is best to use split grafting, and it is most suitable to take xylem bud grafting in the growing season.

Grafting technology: Different methods need different technologies, but one thing is the same, that is, the cambium of rootstock and scion must be aligned and tight. At the same time, if it is seedling grafting, the height of rootstock is generally 10~ 15cm, and the high grafting depends on the specific situation.

① Abdominal cutting grafting: when grafting, the scion is cut into wedges with the same length and width, and the length depends on the thickness of the scion, with a thickness of 2-2.5 cm and a thickness of1.5-2 cm. Then, according to the length and width of the scion section, a cut with the same length and width as the scion section is obliquely cut on the rootstock with an opening of about 1cm, and then the scion is inserted into the cut of the rootstock, preferably with all three sides aligned. If beginners can't align all three faces, they must also align any face with the cortex (cambium) of the upper rhizome. Finally, tie it tightly with plastic film.

② Subcutaneous transplantation: (also called skin grafting) is suitable for root transplantation, near-surface transplantation and high-level transplantation. The operation method is as follows: firstly, one side of the scion is cut to a length of about 3cm, and the opposite side of the base is cut to a length of about 0.5cm for standby, and then the smooth and unbranched side is selected on the rootstock; Use a grafting knife to cut a knife longitudinally from the upper mouth to the xylem, with a length of about 2.5cm. After cutting, insert the cut scion between the cortex and xylem of the rootstock from top to bottom, and pay attention to the long face of the xylem. The insertion depth should be 0.3 cm above the scion (white). Finally, it is forbidden to bind with plastic film.

③ Splitting: First, cut the scion into two symmetrical inclined planes. Make it wedge-shaped with a section of 2.5~3cm, and the section should be straight, smooth and clean. The branch skin should not be tilted, and the surface left outside should be slightly wider than the surface. Then chop a knife in the middle of the rhizome from top to bottom. The appropriate depth is 2.5~3cm, pry open the crack of the rootstock, insert the scion into the rootstock from top to bottom, and pay attention to the cortex of the scion and rootstock. & gt

Question 5: How to plant jujube seedlings There are five ways to cultivate jujube seedlings:

1. Grafting seedling: Grafting the required varieties with jujube seedlings or rootstocks to obtain seedlings. Grafting methods mainly include wood bud grafting and branch grafting (branch grafting mostly adopts subcutaneous grafting). The main points of grafting technology can be summarized as six words: "fresh", the scion remains fresh and there is no water loss. "Flat", the cutting surface of the scion should be flat. "Quasi", the cambium of scion and rootstock should be aligned. "Tight", tie it tightly after connection. "Fast" operation is faster. "Wet", after grafting, bury the soil or cover it with plastic bags to keep the humidity. At the same time, 5-7 days before grafting, the rootstock nursery is irrigated to make it easy to peel.

2. Root-cutting seedling: select excellent varieties of self-rooted plants, dig a ditch with a width of less than 30-40cm and a depth of about 50cm around the crown before germination, cut off roots with a diameter of less than 2cm, apply organic fertilizer in the root-cutting ditch, and then backfill. Roots and tillers can be produced in the growing season. The roots and tillers are dug out in the next spring, treated with ABT rooting powder or other hormones, and planted in the nursery to cultivate strong seedlings.

3. Root-cutting and seedling raising: combining autumn ploughing, collecting roots from robust jujube trees, cutting root spikes with a length of 20-30cm and a diameter of 1-4cm, and storing sand in an underground kiln. In the spring of the following year, the roots and ears were inserted into the ditch at an angle of 450, 2cm above the ground, and watered immediately after insertion. Roots and spikes are treated with rooting hormone and covered with plastic film, and the effect is better.

4, tissue culture method to cultivate seedlings:

Several factors of in vitro rapid propagation of jujube in Minqin Garden were analyzed and studied, and the most suitable explants-buds and stems cultured in water in early spring were screened out. The initial medium was solid-liquid two-phase culture of H94+IBA 0.1mg/L+NG15 mg/L solid medium and H66 nutrient solution. The subculture medium was H66+NG20mg/L+IBA0. 1mg/L, and the average proliferation coefficient was 4 after 30 days of subculture. The rooting medium was H94+NG3 ~ 8 mg/L+iab0.1mg/L, and the rooting rate was 90%. After 20 days in the tissue culture room, it was cultured in the sunlight greenhouse for about 10 days, and then the bottle stopper was opened for 3 ~ 4 days. The survival rate was 96% by using the transitional transplanting method of Qinghe sand.

When the test-tube seedlings grow on the rooting medium for about 20 days, and the height of the seedlings reaches 4-6 cm, and there are more than three seedlings, they are cultured in the solar greenhouse for about 10 days, tempered for 3-4 days, and then transplanted to the sterilized seedbed (the seedbed method is the same as the green branch cutting seedbed method in the experimental method), and the transplanting depth is 3cm, and the survival rate can reach 96%.

Taking the root system of tissue culture seedlings as cutting material, it is easy to survive. However, the cutting conditions in the field are harsh, the thickness should be above 1cm and the length should be between 15 ~ 20 cm. Even if rooting agent is used, the rooting rate is very low.

5. Cutting technology of jujube trees with green branches: With the development of science and technology, cutting trees with green branches has been used as a rapid seedling raising method. Green branch cutting has the advantages of good reproductive characteristics, simple equipment and easy technology, showing potential development prospects. Through the popularization and popularization of this propagation technology, it will become another conventional seedling raising method of forestry asexual propagation.

Management of jujube green branch cutting technology

1. Selection of nursery land: the nursery land for cutting should be selected in a place with convenient water use, fertile land and flat terrain, and it should also be considered to be close to the mother tree, so as to take cuttings on the spot and insert them as they are picked.

(2) Equipment preparation (manual spraying or sprinkling): plastic pipes, nozzles, faucets and valves for 4-6 minutes; Sprinkler, shed film, river sand, carbendazim, phoxim, NAA, IBA, alcohol, measuring cylinder and talcum powder.

(3) Make a bed and build a shed (including plastic shed and shade shed): After the soil is deeply turned, apply a proper amount of base fertilizer (sheep manure, etc.). ) and use 0.2% phoxim to control underground pests. After the land is leveled, river sand is spread on the soil. The sand bed is 3-5cm thick and disinfected with 0. 1% carbendazim. The bed surface is about 1.5m wide and about 5m long. After the sand bed is completed, a small plastic bow shed will be built with a top height of about1m. At the same time, a sunshade fence will be built on it: the height exceeds1.8m. ..

④ Preparation of drugs: dissolve NAA or IBA with 95% ethanol, and prepare it with distilled water (or cold boiled water) to the required concentration; Talcum powder is made into paste with the prepared solution for cutting.

⑤ Collection of cuttings: According to the quality requirements of cuttings, cuttings should be packed in plastic bags during collection and transportation. It should not be exposed to the sun for a long time to prevent the leaves from losing water and wilting. The harvest should be finished before nine o'clock in the morning. If the cuttings need long-distance transportation or two or three days to cut, they must be stored in a cool place with air humidity above 80%.

Cutting quality requirements: jujube takes a long time to take root and consumes a lot of money ...

Question 6: Jujube trees and several fruit trees can be grafted. The rootstocks commonly used for jujube tree grafting are this rootstock (that is, jujube seedlings or seedlings or other varieties of jujube) and jujube.

In addition, in the south of the Yangtze River, the copper tree of Hippophae of Rhamnaceae was also used to graft jujube trees.

Question 7: What is the difference between grafted seedlings and root seedlings of jujube trees? There are protrusions on the grafted seedlings, which are no longer obvious at the interface after a long time. Generally, the trunk lines of seedlings are symmetrical, and there is no knot phenomenon like grafting.

Question 8: The common propagation method of jujube trees is grafting or branching. When grafting, rootstock or jujube is used, and the scion uses the secondary branch on the head of 1 ~ 2a jujube. Seeds of this rootstock or jujube are sown in autumn or spring after sand storage. Subcutaneous grafting is the main grafting method of jujube, which has the advantages of lax requirements on the thickness of rootstock, easy collection of scions and high grafting survival rate. It can be carried out during the peeling period of rootstocks, especially from before and after germination to the vigorous period of new shoots. The rough stock can be grafted by split grafting, and the suitable grafting time is 15 ~ 20 days before germination. The ramet is based on the root tiller of jujube, and the root tiller can be properly thinned when it is too dense. In addition, self-rooted jujube trees can also be used for rooting and seedling raising. In recent years, the cuttings of 1a shoots and hard branches treated with rooting powder have a higher survival rate. The common methods of jujube seedling raising are branching, grafting and oblique crossing. (1) No ramets were found; This is a traditional method of jujube propagation in China. Mainly using the characteristics that jujube roots are easy to form adventitious buds and germinate. Propagation of seedlings by cultivating root seedlings. Although this method can maintain the excellent characteristics of the mother plant. However, the number of seedlings is limited. There are three ways to cultivate rootstock seedlings: one is to plant a tree disk, which damages the root thickness 1 ~ 2cm, and the wound forms adventitious buds to grow rootstock seedlings; The other is furrowing between rows. Dig a furrow with a depth of 40 cm and a width of 30 cm from the periphery of the crown, cut off fine roots below 2 cm, cut off root segments, and spread loose wet soil to promote root tillering. Thirdly, the tiller seedlings formed in the field in 1 year should be sown in summer and autumn, and the leaves should be cut off during seedling raising. After the seedlings are raised, they are watered and planted, with more than 5,000 plants per mu, which will be planted in two years. (2) Grafting method: Commonly used grafting methods include split grafting, cut grafting, subcutaneous grafting and bud grafting. (3) Cleavage is usually carried out before germination 15~20 days. The diameter of rootstock is 1. Split more than 5 cm, thinner competition. The first branch of 1~2-year-old jujube was selected as the scion, and the conventional grafting method was adopted. (4) Subcutaneous transplantation is also called bag transplantation. It can be carried out from the beginning of liquid flow to the whole peeling period, especially from before and after germination to early July. Pay attention to grafting during the growth period. Immediately cut off the branches and leaves of the scion, put them in a bucket with a little water, and then wrap them with plastic strips to keep them moist. It is best to cover it with plastic bags, but it should be broken and ventilated in time after survival. (5) It is better to take budding with wood, and take the development branches which can be lignified and not lignified at flowering stage as scions. This method has the dual characteristics of bud grafting and branch grafting. Also known as tender shoot grafting. Suitable for grafting and seedling raising of seedlings and rootstocks. (6) Brazing insertion method: there are two kinds: root cutting and cuttings. Cuttings are difficult to take root and the survival rate is extremely low. The survival rate of root cutting is better. According to the experiment of Taigu Agricultural School in Shanxi Province and Hunan Forestry College, the root segments with the diameter of 1 ~ 3cm and the length of 10 ~ 20cm were inserted obliquely in the open-air seedbed, and the top was covered with 5 cm. Regular watering and moisture retention can improve the seedling rate and make the seedlings grow vigorously.

Satisfied, please adopt.

Question 9: How many months have you been planting black jujube seedlings? Thank you. A. planting black dates to prevent insects and diseases.

First, the main points of colonization

Dig a planting ditch with a row spacing of 5m, width and depth 100 cm ×80 cm. When filling ditches, the topsoil and organic fertilizer are mixed and filled into the bottom layer. Choose healthy seedlings with stem diameter above 1 cm, complete root system, no pests and diseases, and no damage for field planting. Digging a planting pit in mid-March, adopting a rectangular planting method, watering 1 time in time and spraying 800 times of new high-fat film after planting according to conventional planting techniques can effectively prevent evaporation of water on the ground and transpiration of seedlings, isolate pests and diseases, shorten the slow seedling stage, and make plants adapt to the new environment quickly and grow healthily.

Second, the management of soil, fertilizer and water.

After the garden is built, before freezing every autumn, the soil outside the planting ditch should be widened by 100 cm every year, and the surface mixed organic fertilizer should be applied at the bottom of the ditch to create a good soil environment for root growth.

Every year, 50 kg of organic pigsty fertilizer and 2 kg of phosphate-nitrate compound fertilizer are applied to every 100 cm ditch in combination with the autumn ditch expansion and soil improvement. At the same time, 20 kilograms of pig manure was applied to each black date.

After watering in spring, loosen the soil 1 time, then spray herbicide 1 time to remove weeds in the garden, and spray it 2-3 times a year. After picking fruits in autumn, combine with the application of organic fertilizer in autumn to carry out deep ploughing in the whole garden.

Third, shaping and pruning

1. Pruning of young trees: thinning out competing branches, upright strong branches and tightly squeezed branches, retracting the weak branches and drooping branches that have already borne fruit, and placing the extended branches of the central trunk and main branches at all levels for a long time.

2. Pruning in the full fruit stage: the black jujube cultivated in medium density enters the full fruit stage in the fifth year. The pruning tasks at this stage are as follows: thinning out the large branches and large branches in the periphery and upper part, improving the illumination in the inner room, and promoting the germination of new branches through hidden buds in the inner room; Thinning drooping branches, retracting excessively long fruiting branches, maintaining tree vigor and stabilizing yield.

The wound caused by pruning should be sealed with "calluses antiseptic film" in time to prevent dryness and invasion of pests and diseases.

Fourth, disinfection and sterilization

Before sprouting in winter and early spring, spray the trees with the mixture of "universal tree protector" and sulfur to keep warm and prevent freezing, and eliminate the wintering places of pests and diseases.

In a word, black dates have excellent characteristics such as early fruiting, easy management and pest resistance, which are deeply loved by fruit farmers. In order to achieve high and stable yield of black dates, it is especially necessary to strengthen the management of the above aspects.

Question 10: Is jujube a root tuber plant or a seed plant? There are two basic methods of artificial propagation of jujube, one is rooting, the other is grafting, and both of them are rooting.
