First, the top-dressing apricot tree consumes a lot of nutrients after a lot of fruiting. After flower unloading, it is a flower bud differentiation period, which requires a sufficient supply of nutrients. Therefore, timely recovery of fertilizing materials and timely nutrition. Topdressing is generally based on soil-fertilizer, chicken manure, and sheep manure, combined with nitrogen, phosphorus, and potassium elements and elemental element fertilizers. The method of fertilization can be used to dig trenches, and it is not necessary to water the rainy season.
Second, clean gardens combined with topdressing, the weeds, fallen leaves, rotten fruit, pests and diseases in the orchard in a timely manner to clean up, buried in order to prevent pests and eggs from spreading harm.
Third, pest control apricot tree most likely to produce red spider, red spider damage leaves, will cause early leaves, affecting flower bud differentiation, less flowers in the coming year, less fruit, low yield. Red spiders can be used to control 15% of wolfberry 1000 times, or 1.8% abamectin 3000 to 4000 times.
Fourth, the summer cut is the supplement of winter pruning, summer cuts in time, can save nutrients, improve ventilation and light conditions. The upright branches, cross branches and overlapping branches should be cut off in time. For a tree with a small open angle, you can use a rope to pull a branch, or use a brick or stone to drop a branch.
Pruning and pruning, after the fruit is picked, the young Wang branches are opened and the new shoots continue to pick up the heart twice. In addition, pests and branches, cross branches, thin and weak branches and legged branches in the canopy should be cut off to reduce nutrient consumption of the tree.
5. Fertilizer Apricot trees should be applied with quick-acting fertilizer once after fruit picking. Each mature tree topdressing urea 0.5 ~ 0.75 kg, or diammonium phosphate 0.75 kg, watering immediately after application. Top dressing should be done in small amounts and apply in soil below 15 cm. Before the fall of apricot trees, a basic basal fertilizer is applied (from September to October). The basal fertilizer is mainly composed of high-quality farmyard manure, mixed with a small amount of potassium phosphate fertilizer, and applied to the vertical projection of the outer edge of the canopy in a vertical plane of 30 to 50 cm. Usually 5 to 6 years of fruiting apricot apricot plant fertilizer 30 to 50 kilograms, superphosphate 0.3 to 0.5 kilograms; fruit period apricot tree planting fertilizer 60 to 100 kilograms, superphosphate 0.6 to 1.0 kilograms. In combination with the control of pests and diseases, foliar spraying of 0.3% potassium dihydrogen phosphate solution 2 to 3 times, watering after fertilization.
Sixth, the modified apricot fruit should be cultivated in the whole garden after harvesting, combined with deep fertilization. Through deep turning, soil structure can be improved, root growth can be promoted, cold resistance can be improved, and the wintering base of pests can be reduced.
