1, pay attention to topping. Before the end of September, all the uncapped new shoots will be removed from all the unfinished parts, so that the nutrients flowing into the growth point will accumulate in the lignified tissue, which will promote the leaf hypertrophy and strong photosynthesis. The branches are highly mature and the buds are full.
2, pay attention to the branching. Combined with the re-picking of the heart, all kinds of long branches and dense branches that need to be cut off during winter shearing are eliminated, reducing the amount of pruning and nutrient consumption in winter, and improving the nutrient storage of the tree.
3, pay attention to deep turn the tree. It is advisable to deepen the expansion of the outer edge of the planting root, increase the application of organic fertilizer, and mature the soil. Generally, a plant can be completed in two or four years, with a depth of 60-80 cm, in order to deepen the root distribution layer, improve the permeability of the soil, and is beneficial to retain water and fertilizer, and enhance the ability of roots to absorb water and nutrients.
4, pay attention to autumn fertilizer. First, foliar fertilization, spray 2-3 times 0.3-0.5 kg of superphosphate and 6% of ash ash in mid-August to mid-September; second, soil fertilization, preferably in September, planting 100-150 kg, appropriate to mix some ammonia, nitrogen fertilizer.
5, pay attention to flood control. For the fruit garden, it is necessary to dredge the ditch in time, drain the water as soon as possible, open the upper surface of the root neck of the fruit tree, accelerate the soil ventilation, and promote the early recovery of the root system.
6, pay attention to protect the woods. Spraying ferrous sulfate Bordeaux mixture in August, it has the effect of killing bacteria. The preparation ratio of ferrous sulfate Bordeaux mixture is: 3 kg of ferrous phosphate, 3 kg of quicklime, 100 kg of water, first dissolve ferrous phosphate with 30 kg of water, make ferrous sulfate solution, and then extract a small amount from the remaining 70 kg of water. Water, the lime is dissolved, and finally the ferrous sulfate solution is slowly poured into the lime milk.
