Key points of cultivation and Management of Dabian Apricot

1. Before planting, soak the roots of seedlings in water for 24 hours, take them out and dip them in water-retaining agent, and then plant them. After planting, it is filled with water, and when the water seeps, it is set to dry at 80cm to 100cm. The planting hole takes the trunk as the center, covering 1 meter × 1 meter plastic film, the surrounding of the film is compacted with soil, and the surrounding of the planting pit is slightly higher. Through years of practice, it has been proved that plastic film mulching after planting can not only retain water, but also increase the ground temperature, make the tree germinate early and grow fast. One week after planting, the trunk was covered with a plastic bag, which was 40 cm long and 10 cm wide. To prevent wind damage, fasten the middle and lower mouth of the bag with a rope. This method can not only prevent dehydration of seedlings, but also prevent the harm of oriental beetles and weevil. When the leaves of the seedlings are as big as the normal leaves, tear the upper part of the bag before 10:00 or 16:00 every day, take off the bag on a rainy day or sooner or later, and wipe off the tillers at the same time. When planting for 15-30 days without rain, you need to replenish water once. The survival rate of planting with the above methods is more than 90%.

two。 The winter pruning of young trees is carried out from January to March every year, mainly shaping, setting up a good skeleton, and laying a good foundation for high and stable yield. When cutting in winter, the central trunk and the main side branches are all cut short at 40 cm, except for competitive branches, cross branches and dense branches, and the rest are put slowly. In order to make young trees bear early and high yield, summer pruning is particularly important. In June, we began to pull branches, pulling the main branches to the base angle of 50-60 degrees, and other branches to 90 degrees. And erase the buds in the lower part of the first main branch and the upright buds and competitive buds on the back of each main branch, improve the ventilation and light transmission conditions, and transform vegetative growth into reproductive growth.

In the full fruit period, the extended branches of all levels of backbone branches should be moderately cut short, and the fruiting branch group should be renewed in time, and the thin branch group and the weak branch group should be rejuvenated in time to promote the emergence of new branches at the base and form a new fruiting branch group. In order to prevent the tree from being bald due to lack of light and causing it to sprout new branches, the fruiting branch group should be updated in time to form a new fruiting branch group to ensure high and stable yield year after year.

3. Fertilizer and water management fertilizer application pit should be slightly deeper, it is necessary to dig a 40-60 cm deep and 50 cm wide annular ditch outside the tree, mix fermented straw fertilizer and other farm manure with phosphate fertilizer, and apply 50 kg per tree in full fruit and 20 kg per young tree. Topdressing was carried out twice, the first time before flowering, and the quick-acting fertilizer dominated by nitrogen fertilizer could not only increase the fruit setting rate, but also benefit the growth of roots and shoots. The second time was carried out in early August after fruit harvest, and the application of compound fertilizer based on phosphorus and potassium fertilizer could quickly restore tree potential, promote flower bud differentiation and increase complete flowers.

Dabian apricot has strong drought resistance, which can be irrigated 2 to 3 times a year. One is to irrigate 2 buckets of water per ditch after fertilization in autumn, the other is to irrigate once with topdressing before flowering, and once in spring when it is especially dry.
