The leaves of apple trees before the end of September basically completed. The early accumulation of organic nutrients in the deciduous fruit trees decreased significantly, which affected the later differentiation of flower buds and flowering and fruit setting in the next year. It had an adverse effect on the overwintering of fruit trees, and rot disease and early defoliation disease also aggravated. In order to reduce losses, winter and spring should focus on some remedial work.
The earlier the use of basal fertilizer, the sooner the better the basal fertilizer is, the better the manure is. Specific fertilization amount: In the fruit stage, the fruit tree will be applied to 3,000 kg of high-quality farmyard fertilizer per 667 square meters, 100 kg of superphosphate, 50 to 75 kg of ternary compound fertilizer, and the young tree and the initial result tree will be reduced.
Timely clearance of clear orchard leaves, diseased fruit, weeds and broken branches in the orchard are removed, burned or buried deeply. After clearing the garden, the whole tree was sprayed with 1 to 2 times of strong ring vein net, rotted wheel special, agricultural anti-l20 and lime sulfur mixture, etc., for disinfection and sterilization.
The white deciduous trees on the trunk of the trees are low in nutrients stored in the trees, and are prone to frost damage. After coating, they can reduce the occurrence of sunburn and freezing damage, and can kill some of the diseases and insects that overwinter in the bark joints. The main material of the whitening agent is lime sulfur, auxiliary materials are lime, salt and lard. The ratios are: 1 kg of lime sulfur, 3 kg of lime, 0.5 kg of salt, 0.25 kg of hot lard and 15 kg of water. Brush the trunk after stirring the above materials. Saplings can also spray antifreeze on the tree 1 or 2 times at the beginning of winter.
Scientific pruning of early deciduous trees is generally pruned after dormancy and before winter.
