Durian is a famous tropical fruit, most of the durian in China now rely on imports, with the most durian in Thailand.
With the increasing demand for durian, it is now also planted in our country, mainly in Guangdong and Hainan, China. I remember when I traveled to Hainan in 2021, I discussed the durian planting methods with the durian growers in Hainan, and I will share the planting methods I learned with you.
1, reproduction
Durian reproduction methods include seed propagation, grafting, cuttings, pressing and so on. Seed propagation is simple and easy to seedling, but the shape of the durian tree is more variable, some quality durian seeded out may be inferior durian tree, and inferior durian seed can also cultivate high-quality durian, the direction of the progeny mutation is unpredictable so, generally do not choose the way of seed propagation. The most commonly used method is grafting, followed by cuttings. Grafting is categorized into budding, leaning and splitting.
2, grafting method
Durian can be grafted throughout the year, split, then the rootstock is generally selected after sowing growth but the leaves have not yet unfolded seedlings, the rootstock flat cut and then cut out the middle of the 1 cm deep interface, the scion selected and the diameter of the rootstock is equivalent to the branch with 1 to 2 buds, the leaves will be cut off part of the reduction of leaf transpiration, the scion cut out of 1cm deep interface. Leaf transpiration, scion cut into a wedge shape connected to the rootstock interface, fixed with plastic wrap, placed in a cool place, avoid sun exposure, after a period of time to observe whether it is alive.
3, planting management
After grafting, when the seedlings grow to a height of about 40 cm can be planted, planting is best to ensure that the roots have *, to facilitate the improvement of the survival rate. General planting requirements for plant spacing 3 meters, row spacing of about 5 meters. Planting before the application of adequate fertilizer, base fertilizer generally include organic fertilizer with * miscellaneous fertilizer, as well as some lime. Durian planting time requirements are not strict, so you can plant all year round.
4, fertilization and pruning
Durian trees planted after the survival of the tree, especially after the beginning of the results, to timely fertilization and pruning tree shape. General planting about 2 years to be pruned once a year after the fruit picking should also be pruned. Fertilizer is generally in the bud and fruit expansion period, especially the fruit expansion period to apply enough organic fertilizer to ensure that the durian fruit expansion growth, in order to increase production.
5, pest control
Durian aphid control can be sprayed once a week or so more than 1000 times. Durian mealybugs on the pharmaceuticals can be used to kill lice essence of 15 grams plus 10 liters of water, spraying the whole sapling, once a week, until the mealybugs are extinct, generally sprayed two to four times can be. Durian termites can be used 15 ml of elixir with 10 liters of water sprayed on the infested area, every interval has been two weeks of spraying, until the termites are extinct. Durian leaf anthracnose can be sprayed with "Dakonin" or "Woboli".
6, ripe harvest
Durian ripening season in November, February and June-August, these seasons are its ripening period, to the fruit ripening should be carefully observed, when the fruit turns orange-yellow or orange-red is ripe, then can be harvested. It is not easy to eat immediately after harvesting, need to be after a week of time, and so its flesh is soft before eating.
Summary, the development of durian planting profit is still very substantial, but in the process of planting durian, must master the technology as well as good pest prevention.
