There will be a growth peak after the apple is harvested. There is still 30 to 40 days of growth time in the shoots of the shoots. The differentiation of flower buds continues and the shoots are gradually enriched. At this time, the management of basal fertilization, spraying of leaves, and autumn pruning will be carried out to increase the nutrient level and cell concentration of the tree, which will benefit budding and flowering of fruit trees and early growth of new shoots.
1. Early application of basal fertilizer after early harvesting of Shiji, and timely absorption and utilization by Hunchun to prevent frost damage in the root zone. The saplings are applied to the annular groove and fertilized every year from the outer edge of the planting pit. The results are that organic fertilizer is applied to the trees. Usually, the fertilization in the trenches, the whole garden is applied, or both are replaced every other year, and the trace element fertilizers are appropriately applied. .
2. After the protection of the branches and leaves is harvested, photosynthesis of the leaves is still underway, and care should be taken to protect the leaves. After the autumn can be sprayed with 0.5% urea, 0.3% potassium dihydrogen phosphate, in particular, spraying young potassium dihydrogen phosphate can prevent drawing. Fruit trees that are seriously damaged by pests and diseases should be sprayed with a growth regulator to protect the tree.
3. Prevention and control of pests and diseases Neglecting orchard pest control and disease prevention in the later period will cause a large amount of defoliation in fruit trees, seriously affecting the fruit yield and quality. According to the pest situation, every half month of spraying control can be used diflubenzuron 3, 1500-2000 times liquid, abamectin 3000 times liquid and so on.
4, pruning autumn to continue to pull sticks, picking the heart, the main branch drawn into 70-80 degrees, auxiliary branches, leggy branches can be pruned or pulled branches into a 90-degree angle above, in early September on all the backbone branches, extension branches, The vegetative shoots were cut off from the young part of the shoot. As a result, the big tree had sparse and retractive treatment of the dense branches, cross branches, leggy branches, and disease branches and branches, and the remaining branches were pulled horizontally.
5, the application of paclobutrazol on apple juvenile tree, age-ineffective or oligo-producing wang tree, under the main branch can be dug 15-30 cm deep ring ditch, and then paclobutrazol into a water solution evenly poured into the ditch, and then covered with soil .
6. Deeply turning weeding and basal fertilization to turn the whole garden will help improve deep soil physical properties and promote nutrient conversion in soil. Clear the weeds, the branches and leaves of pests, diseases and insects in the garden, and burn them in a concentrated manner to prevent pests from spawning on them and reduce the source of diseases and insects in the following year.
