Seeds are often used to cultivate durian, but the genetic variability of durian is great. Each seed may produce ten kinds of fruits with different qualities, and inferior durian can produce excellent varieties. Similarly, good durian can also produce inferior varieties, and some real durians will not bear fruit for life. In order to cultivate excellent varieties, ensure the purity, early fruiting and high yield of varieties, grafting propagation is often used to cultivate durian.
bud grafting
Almost all dicotyledonous woody plants can germinate and reproduce except monocotyledonous plants and some plants with irregular cambium. The size of a pencil. Now the rootstock stem leaves the soil 10cm. Cut two slits with a width of 0.7cm and a length of 3 ~ 4 cm from top to bottom, cut a knife at the top of the two slits, and pull the skin up to the same length as the bud. Leave a little skin at the lower end of the incision to hold the bud. The process of bud taking is the same as that of anvil water cutting and lifting. After inlaying, use plastic film tape with the width of 1cm to tie it tightly. It is best not to touch the rain for two days.
Note that except durian, other fruit tree budding methods can completely wrap the buds, because the buds on the buds are easy to fall off. We will know if it is still alive in two weeks. After survival, cut off the upper end of the rootstock about 30cm away from the grafted bud, so that it can quickly grow * * * buds. In the future, rootstocks will breed a large number of rootstocks. These rootstocks cannot be completely removed. One or two rootstocks must be lodging to help the grafted buds absorb nutrients. However, the remaining rootstocks should not be allowed to grow excessively, and they should be pruned frequently so as not to hinder the growth of grafted buds.
Wedge grafting
Seedlings that have not yet grown leaves or become wood are the most suitable rootstocks. Cut the rootstock at a distance of 6 ~ 7 cm, and cut a knife down in the middle of the flat rootstock pile to a depth of about 1cm to form a "V" shape; Take a branch tip with two or three buds equal to the diameter of the anvil stake as a scion, about 8 ~ 10 cm long, cut off 3/4 leaves, flatten the lower end of the scion into a wedge shape, insert it into the slit of the anvil stake, and tie it tightly with a film tape. After that, cover the whole seedling with transparent plastic bags to prevent the scion from evaporation. After about two or three weeks in the shade, if the leaves of the scion do not fall off, it will be successful.
receive
Only suitable for a small number of propagation, plastic bags planted seedlings, about six or seven months can be used as rootstocks. The branch size of scion is similar to that of rootstock, and the most ideal technology is upright nutrition.
Cutting propagation method
The branches used are about 15cm long and the diameter is as big as chopsticks. There should be several leaves and buds, and two-thirds of each leaf should be cut off to prevent water from evaporating. The branch tips are obliquely cut or cut 1 cm from bottom to top, coated with a layer of hormone rooting agent, inserted into a wet sand cup, and watered in a greenhouse with poor light. After seven or eight weeks, if the leaves don't fall off and the young roots grow, they can be transplanted into plastic bags.
Abdominal branch transplantation
The size of rootstock can be arbitrary, as long as it has grown into wood, the cortex is easy to peel off, the cutting tip is arbitrary, and the cutting process is similar to bud grafting. Select 10cm long robust buds that have not yet opened leaves and are not yet mature as scions. The length of the scion is slightly shorter than that of the rootstock incision. Insert it into the rootstock incision, tie it tightly with plastic tape, then wrap it tightly with transparent plastic paper and put it in the shade. Cut off the tape after two weeks, but don't remove the tape until the branches grow out.
air layering
Stratification in the air is not seasonal. Select branches with a larger pencil and tie them about 3 cm long at a distance of about 40 cm from the end. After peeling, it is necessary to cut off the cambium at the incision with the back of the knife, otherwise the incision cortex will recover and cannot take root. Cover the incision with a mass of wet soil the size of a duck egg. Wrap three layers with plastic paper and tie them tightly at both ends. After about three months, the new roots can be cut off from the mother. Cut the plastic paper, plant it in the black plastic bag of fruit seedlings and put it in the shade. It will be transplanted in about a month or two. Durian is rarely used for breeding because of its low survival rate.
Question 2: How to plant durian seeds to germinate? Durian (scientific name: Durio zibethinus Murr) is a huge tropical evergreen tree, native to Malaysia. Some countries in Southeast Asia have more crops, among which Thailand has the most. China, Guangdong and Hainan are also planted. If you are north of the Tropic of Cancer, give up planting. If the accumulated temperature is insufficient, even if it germinates, it will not live long.
Question 3: How do durian seeds grow in small pots?
1. Planting
Durian can be sown every year, especially in spring. The suitable row spacing of sowing plants is 20cm × 20cm. In the seedling growth period, attention should be paid to weeding and fertilization to promote seedling growth. Excellent mother plants can be propagated by air layering, which is easy to take root. It only takes 60-70 days from branch circle to seedling.
2. Seedling colonization
Seedlings can be planted when the height is 30-40 cm, the row spacing is 3m×5m, and organic fertilizer, soil miscellaneous fertilizer and appropriate amount of lime are applied as base fertilizer. It can be planted all year round, especially with soil.
3. Fertilization management
Durian trees should be fertilized/kloc-0 times a year, that is, spring budding fertilizer, summer fruit swelling fertilizer and pre-harvest fertilizer, especially fruit swelling fertilizer. Deep application of organic fertilizer after fruit harvesting.
4. Shaping and Pruning Due to the strong germination ability of durian trees, attention should be paid to shaping after planting 1-2 years, and the fruits should be pruned in time after picking to maintain a good tree shape.
Step 5: Harvest the fruit.
When the durian fruit turns orange-yellow or orange-red, it is ripe and can be harvested. The fruit can't be eaten directly after harvest, and it takes 4-7 days to mature, and it is expected that the pulp will soften before eating.
Because durian can only grow and bear fruit in the climate with high temperature all the year round, even in the equatorial region, the highland above 600m above sea level can not grow durian or bear fruit because of the temperature drop.
Question 4: the planting method of durian 1 If you just want to see what the durian tree looks like, refer to the teaching upstairs, find a clay pot, eat the mature seeds and bury them. Guangdong can be seen in spring, summer and autumn in about a month.
2. If you want to see fruits, you won't have a chance without a big garden. You can go to south china botanical garden to see how tall durian trees need to grow to bear fruit!
3. I tried it several times on the balcony and planted the famous Thai durian gold pillow. Germination is easy, and the seedlings are very strange, which is worth a try.
4. In addition, in Guangdong, durian is suitable for planting in narrow areas along the southeast coast. Further north, it is difficult to ripen durian, and even durian in south china botanical garden can't be eaten. Just like planting bananas in the north, it is always just for appreciation.
Question 5: How can durian seeds germinate? Put it in sand and spray water with a watering can every day. The humidity is about 60%. When the temperature is above 20 degrees, it will germinate.
Question 6: How to plant durian: 1, and the row spacing of sowing plants is 20cm*20cm. During the seedling growth period, attention should be paid to weeding and fertilization. Excellent durian mother plants can be propagated by air layering and easily take root. It usually takes only 2 months from branch circle to seedling.
2. When the young durian tree grows to 30-40cm, it can be planted with a row spacing of 3m*5m, and applied with organic fertilizer, soil miscellaneous fertilizer and appropriate amount of lime as base fertilizer. It can be planted all year round, especially with soil.
3. Fertilization management of young durian trees: Fruit trees should focus on fertilization once a year, that is, spring budding fertilizer, summer fruit swelling fertilizer and pre-harvest fertilizer, especially fruit swelling fertilizer. Deep application of organic fertilizer after fruit harvesting.
4. Pay attention to shaping and pruning: durian trees have strong germination ability, so within one to two years of planting, attention should be paid to shaping, and the fruits can be pruned after picking. A good tree shape is more conducive to durian fruit.
The above is about the planting method of durian. Almost all the owners of coniferous fruit tree planting and development bases are not very good. Fruit tree seedlings are places where people who don't understand learn to plant fruit trees.
Question 7: How to plant the seeds in the middle of durian?
Durian can be planted all year round, especially in spring.
The suitable row spacing of sowing plants is 20cm × 20cm.
In the seedling growth period, attention should be paid to weeding and fertilization to promote seedling growth.
Excellent mother plants can be propagated by air layering, which is easy to take root. It only takes 60-70 days from branch circle to seedling.
Seedling colonization
Seedlings can be planted when the height is 30-40 cm, the row spacing is 3m×5m, and organic fertilizer, soil miscellaneous fertilizer and appropriate amount of lime are applied as base fertilizer.
It can be planted all year round, especially with soil.
Question 8: How long does it take for durian seeds to germinate in the pot? Soak the seeds in water first and change the water every day. In 2-3 days, the white part of the nucleus will crack and root will appear.
Bury this root down into the soil, and then cover it with thin soil about 1-2 cm. In summer, water should be poured every time. It can be shelled in a month.
Question 9: The durian bought last night contains seeds. Can I plant it? It depends on the region.
South fruit
The species in the north no longer exist.
