Question 2: When should lavender be planted? There are four propagation methods of lavender: sowing, cutting, layering and rooting. Cutting and sowing are the main methods.
1. seed propagation: lavender seeds are small and suitable for seedling raising and transplanting. Generally, the sowing date is in spring, March-June or 9-165438+1October in warm regions, April-June in cold regions and winter in greenhouses. The germination days are about14 ~ 21d. The optimum temperature for germination is 18 ~ 24℃. Proper light is needed after germination, and weak light is easy to grow white. Because of the long dormancy period, seeds should be soaked with 12 hours before sowing, and then soaked with 20-50ppm gibberellin for 2 hours before sowing. Before sowing, level the land, water it, soak it underwater and sow it evenly, then cover it with a layer of fine soil with a thickness of 0.2 cm, and cover it with grass or plastic film to keep it moist. Keep the seedbed moist at 15 ~ 25℃, and sprout in about 10 days. It takes a month to germinate without gibberellin treatment. It takes 1 ~ 3 months to germinate below 15℃. Pay attention to spraying water at seedling stage. When the seedlings are too dense, they can be properly thinned and transplanted when the seedling height is about 10 cm.
2. Cutting propagation: Cutting is generally carried out in spring and autumn. Softwood cuttings can also be used in summer. The cutting substrate can be 2/3 coarse sand mixed13 sphagnum moss. Select the well-bred plants with vigorous development, select the terminal buds of one-year-old semi-lignified branches with short pitch and no pilling, and cut at the top 8 ~ 10 cm. The cut of the cutting should be close to the stem node, so as to be smooth and not break the phloem. Remove the leaves from the lower two nodes, soak them in clear water for 2 hours, then cut them into the soil and take root in about 2 ~ 3 weeks. You can also choose 8 ~ 10 cm annual branches and take root in about 40 days under the conditions of good drainage, humidity and bed temperature of 20 ~ 24℃. Don't use the terminal bud of inflorescence, because the aging of flower branches will have an adverse effect on future growth. Plastic film cutting, soil preparation and soil preparation. Cover with plastic film after watering and cut immediately. 5 ~ 8 cm deep and 20 ~ 25 cm row spacing. Pay attention to raising ground temperature and promoting root development; Prune extended branches frequently, remove spikes in time, promote branching and cultivate strong seedlings. The plant spacing is 60cm, and the row spacing is 120cm. Water immediately after planting.
3. Propagation by ramets: It can be carried out in both spring and autumn, with 3-4-year-old plants, and with mature old roots in March-April in spring, each branch has bud eyes.
Question 3: Planting time and method of lavender cultivation environment Lavender likes warm climate, cold tolerance, drought tolerance, light tolerance and waterlogging tolerance. It is not strict with soil, barren-resistant and likes loose neutral alkaline earth with good drainage. Lavender is difficult to grow in southern China because of its waterlogging tolerance, but as an aromatic plant, it is an excellent potted flower.
Lavender seeds are small and suitable for seedling raising and transplanting. Sowing can be done at any time in warm areas all year round, and it is suitable for spring sowing in cold areas. Before sowing, level the land, water it, soak it underwater and sow it evenly, then cover it with a layer of fine soil, 2-3 times the thickness of the seeds, and cover it with grass or plastic film to keep it moist.
Watered lavender likes dry environment and is not resistant to moisture. It is forbidden to water frequently at home, and there should be no water in the basin or ground, so it should be ventilated. After the pot is put away, water it once. The principle of watering after survival is "see dry and see wet". Be careful not to pour water directly on the leaves when watering, and don't let the soil splash on the branches and leaves to avoid diseases. You can also spread a layer of pebbles on the soil surface of the flowerpot, which is beautiful and can prevent diseases. If tap water is used, it is best to use it in the sun for two days.
Lavender in Rizhao is a long-day plant, and light plays a very important role in its development and the formation of aromatic oil. Excessive shading will lead to excessive growth and disease, but it is best to do some shading treatment in hot summer to avoid direct sunlight.
Lavender doesn't need much fertilizer to fertilize. In the spring with rapid growth (March-May), the compound fertilizer of nitrogen, phosphorus and potassium can be applied monthly to make a solution for irrigation, and the concentration is 1%. Too much nitrogen fertilizer can easily lead to excessive growth.
After setting the flower, cut off the first node under the flower and trim the plant into a hemisphere by the way. Usually, dry the branches at any time. In order to control plant height or obtain better plant type, it should be cut again in late summer and early autumn to promote the development of new branches. When the seedlings are too dense, they can be properly thinned and transplanted when the seedling height is about 10CM. It grows very fast and needs to be changed once a year.
There is little pest control. The disease is mainly root rot, and the incidence rate is the highest in high temperature and stagnant water environment. Control method: root irrigation with 800 times solution of carbendazim and chlorothalonil once a month, especially in June-65438+10. Pay attention to prevent water accumulation and keep the air dry.
Question 4: How to plant lavender seeds How to plant lavender seeds:
1, container
Lavender seeds grown at home can be replaced with smaller flowerpots or other containers. For example, in a yogurt box, use an awl to make a few small holes in the bottom of the box. Disposable plastic cups are ok, but because they are transparent, it is best to paste them on the outside with black paper or put a paper cup (if the roots of plants are exposed to the sun, it will affect their growth and the soil will grow green moss easily).
2. Planting materials
Lavender seeds are relatively small, and the germination rate is low, so the soil used for general sowing needs to be loose and breathable, with strong water retention and sufficient disinfection. Soil mixed with vermiculite, peat, water moss, perlite and snake sawdust can be used. You can also configure it yourself if you have the conditions.
Step 3 soak in warm water
Lavender seeds should be soaked in warm water at 40 degrees. Soak for 24 hours after water cooling. It germinates easily.
4. Sowing method
Generally, the seeds are slightly larger (such as lavender and sage), and 2~3 seeds can be ordered in each container. After germination, leave a stronger one according to the growth of the seedlings. Small seeds (such as mayonnaise) can be sown. Touch some seeds with your hands and sprinkle them gently on the soil. Lay eggs after germination. Leave 1~3 seedlings as appropriate.
Step 5 cover the soil
The thickness of the seed cover depends on the size of the seed. Generally 2~3 times the diameter of the seed. Fine seed soil should be thinner, lavender seeds can be covered with thicker soil. Some seeds have strong phototaxis, so they can be uncovered (e.g. sweet bee flower, sweet butterfly).
Step 6 increase moisture
Sowing must be thoroughly watered. Water with a watering can. Don't use force, lest the seeds be washed away. It is best to sit in a basin, that is, put 2/3 pots of water in a big basin and sit the container in the basin. Let the water seep through the hole at the bottom of the container. The water level in the big basin should not exceed the height of the soil in the container. After sowing, the container should be covered with plastic wrap, and several holes should be punched in the plastic wrap to breathe. Put the container in the sun and keep the temperature at about 20 degrees. Most seeds can germinate after a week.
7. Management of lavender seeds after germination
After the lavender seeds germinate, the plastic wrap can be removed. If the seeds are small, you can wait until the seedlings are strong.
8. Transplant lavender into a flowerpot
After the seeds of lavender germinate, the seedlings can grow 4~6 true leaves and then go to the basin. In order not to destroy the roots, it is not necessary to shake off the soil near the roots when transplanting. Move it directly to a small pot and fill the roots with soil. After transplantation, it must be watered and shaded for a few days. Then you can put it in the sun for maintenance.

Question 7: Does lavender have to be planted every year? There is no need to sow every year: because lavender is actually a perennial herb or short shrub, not a herb, although it is called "grass". So once planted, you can enjoy flowers for many years under the condition of proper maintenance. In winter in the north, it begins to sleep when it is below 0℃ for a long time. During the dormancy period, the seedlings can tolerate the low temperature of -20 ~-25℃ and germinate and grow again in the following spring. It is a new perennial cold-resistant flower in the courtyard.
The whole plant has a faint aroma with a slight woody sweetness. Because the villi on flowers, leaves and stems contain oil glands, they will burst when touched lightly and release fragrance. The annual harvest period is: the first crop of flowers is generally from late June to mid-July, and the second crop of flowers is from late September to early June of 10.
Lavender is clustered and branched, usually growing vertically. According to different varieties, the plant height is 30 ~ 40 cm and 45 ~ 90 cm. In mountainous areas with quite high altitude, a single plant can grow to1m. Leaves alternate, elliptic-lanceolate, or large needle-shaped, and the leaf margin rolls back. Spike terminal, 15 ~ 25 cm long; Corolla lower tubular, upper lip-shaped, upper lip 2-cleft, lower lip 3-cleft; The flowers are about 1.2 cm long and have blue, deep purple, pink, white and other colors. The common color is purple-blue, and the flowering period is from June to August.
Islands native to the Mediterranean coast, Europe and Oceania, such as Provence town in southern France, are widely cultivated in Britain and Yugoslavia. The northern foot of Tianshan Mountain in Xinjiang is at the same latitude as Provence in France, with similar climate and soil conditions. It is a lavender planting base and the hometown of lavender in China. Lavender in Xinjiang has been listed as one of the eight famous varieties in the world. Like to do it. These flowers are spike-shaped and have slender stems. The flowers are covered with star-shaped fine hairs, with purple-blue florets at the tip and gray-green narrow leaves. These plants can reach a height of 90 cm and usually bloom in June. Whenever the wind blows, a whole lavender field fluctuates like a deep purple wave, which is very beautiful.
Please adopt it if it helps.
Question 8: How to grow lavender? Lavender seeds are difficult to germinate, and it takes a month to germinate directly in the soil. There are generally two ways to accelerate germination: 1. Put it on a paper towel and keep it moist until it germinates. 2. Soak in the seedling pot to accelerate germination. The sowing date of lavender seedlings is generally better in spring, but it can also be sown in greenhouse in winter. Because of the long dormancy period of seeds, seeds should be soaked for 12 hours before sowing, and then soaked with 20 ppm ~ 50 ppm gibberellin for 2 hours before sowing. The sowing depth is 0.2-0.4 cm, and the seedbed should be moist, and the seedlings will emerge in about 15℃-25℃ and 10 days. It takes a month to germinate without gibberellin treatment. Lavender doesn't require much soil, but it should be cultivated in fertile and loose loam, which is suitable for slightly alkaline or neutral soil. Like sunshine, heat-resistant, drought-resistant, cold-resistant, barren-resistant, salt-tolerant, but if it is waterlogged for a long time, it will die. The optimum germination temperature is 65438 0.8℃ to 22℃, and it can grow at 5℃ to 30℃. When the temperature is higher than 38℃ to 40℃ for a long time, the top of stem and leaves are yellow. In northern winter, when the temperature is lower than 0℃ for a long time, the seedlings can tolerate the low temperature of -20℃ to -25℃ during dormancy. Choose sunny and well-drained plots, prepare soil and transplant them after preparation. Transplanting seedlings with leaves, with row spacing of 20×30 cm, and managing according to the seedling situation after survival. Lack of fertilizer (pay attention to applying more potassium fertilizer), lack of water. In winter, you can overwinter in the north with a little plastic film. It should be noted that lavender has almost no pests and diseases, so there is no need to spray pesticides. The following is a method for a flower friend to operate my rose lavender seeds. Some of them have been treated with gibberellin (Weibang sells it, and it is 2% emulsifiable concentrate, so water can be used directly), and some of them have not been treated with gibberellin. Finally, all germinate with kitchen paper towels. I check it twice every morning and evening and find that the germinated seeds are planted in the soil immediately. Insert a hole in the soil with a toothpick, put the germinated head down, and a few days later the seedlings will emerge! I have more than n kinds of small fumigants now. Hehe ... So is Rosemary. Those that don't germinate have been wiped out. Germinated ones can be germinated with paper towels. The germination rate of lavender is not high, and the breeding period is quite long. I brought home 50 kinds of fumigated seeds from abroad, and finally only one Ms fumigation, three Sidkot fumigation and one Vera fumigation grew (these are all relatively high germination rates for me, but the seedlings are easy to die). The north is more suitable for planting, because fumigation requires alkaline soil and sunlight. It is not recommended to fumigate with English roses (it is not easy to germinate, only this one), because lavender is likely to be eaten when it grows up. I'll tell you the details after I check the information. I planted it last year, hehe, because I didn't prepare it in advance, it was all ruined. . . :(
Question 9: How to plant lavender poplar/raw /55 1/46530- 1 (lavender) word = lavender &; In = 76 Yannan3 19。 Blog River/Yannan319/Inc/Sharon Mimosa in 003.jpg is a perennial herb, commonly known as "mimosa" and "sensitive grass". Plant height 30-60 cm; Stems are vine-like, multi-branched, with scattered barbed hairs and prickles all over the body; Petiole length1.5-4cm; Stipules lanceolate and setose; The leaves are pinnate, 2-4 pieces are arranged in palm shape, and the leaflets are rectangular, which will close and droop when touched; Many flowers, head-shaped, generally pink, bloom in July-65438+10; Fruit pods are flat, with bristles on the edges, 3-4 pods, 2 capsules per pod, and automatically fall off after maturity. The reason why Mimosa is "shy" is that Mimosa passes through * * *, with closed leaflets and drooping petioles. The research team led by Takashi Tsuya, a Japanese professor at sophia university, uncovered the mystery of the closed movement of mimosa: the cells of mimosa are supported by tiny reticular protein "actin". When the closed movement occurs, the phosphoric acid of actin will fall off. As long as the mimosa is allowed to absorb the compound that does not let the phosphoric acid fall off, it will not change after contact. Professor Tsuya pointed out that when actin bundles are dispersed, cells are destroyed, resulting in water depletion and closed movement. Femoral actin generally exists in animal muscle fibers and is related to muscle contraction. I didn't expect it to be found in mimosa. It's quite rare. The main application of mimosa is 1, which is ornamental. Mimosa is scattered in a plant shape, with slender and beautiful feathers, and the leaves close at the touch; Mimosa flowers are numerous, delicate and touching, giving people the impression of being weak and delicate. It can be planted in the corner of the courtyard or potted in the window. 2, medicinal. Mimosa is also a medicine. It is slightly cold, sweet and astringent, and has little toxicity. It has the effects of tranquilizing, calming, detoxicating, removing blood stasis, relieving pain, clearing away heat, inducing diuresis, stopping bleeding and astringing, and is often used for neurasthenia, traumatic injury, hemoptysis and herpes zoster. Harvesting in summer and autumn, weeding, drying or fresh use. 3. Predict earthquakes. According to Turkish seismologist Erjiang, a few hours before a strong earthquake, the leaves of mimosa, which are sensitive to external touch, will suddenly shrink and then wither. In earthquake-prone Japan, scientists found that mimosa blooms during the day and closes at night under normal circumstances. If the leaves of mimosa are closed during the day and open at night, it is a precursor to an earthquake. For example:1938 65438+1October1At 7: 00 in the morning, the mimosa began to bloom, but by 10, all the leaves suddenly closed. Sure enough, 13 had a strong effect. During the period of 1976, members of Japan Earthquake Club observed the abnormal closure of mimosa leaves many times, and then an earthquake occurred. Planting Mimosa Mimosa has simple planting technology and extensive management. The requirements for climate, sunshine and soil are not strict, but fertile and loose sandy loam is the best, as long as you are happy ... >>
I always like to eat shortbread, take a bite and smell sesame seeds! Lard is crisp and fragrant, but I'm still afraid of being fat inside, s
