During the appropriate harvesting period for suitable harvested apples, 2 to 3 batches should be harvested to maximize production and quality. "The first batch of first-selected peripherally colored fruit of the crown will be left to be harvested after the poor coloring. The second batch of harvesting should be carried out one week after the previous batch harvesting, and the colored fruits should be selected. The harvest was completed one week after closing." Ma Zhifeng said. Prevention and treatment of late-ripening apples should focus on the fruit before spraying 1 ~ 2 calcium chloride solution to prevent the fruit during storage during bitter pit disease, red spot disease and other physiological diseases. In addition, before harvesting, spray 70% thiophanate-methyl 800-1000 times or DuPont-Eco Safe 1200-times on the entire tree to prevent ringworm disease and brown rot before and during fruit ripening. After the protection of the harvested leaves is completed, 0.5% urea solution shall be sprayed on the whole tree in time to protect the leaves, delay leaf senescence, prevent leaves from falling off prematurely, increase the photosynthetic capacity of the leaves, and maximize the growth of the tree. Nutrition accumulation. Apply base fertilizer to apples immediately after harvesting basal fertilizer, the sooner the better. Basal fertilizer is mainly organic fertilizer, such as pig manure, cow dung, oil residue, etc., and with nitrogen, phosphorus, potassium compound fertilizer. For orchards with deficiencies (such as lack of boron, zinc deficiency, iron deficiency, etc.), a certain amount of trace element fertilizer should be added to the basal fertilizer. Prevention of Insects In mid-October, Daqingye can still lay eggs, reaching the peak before falling leaves at the end of the month, especially in young plants with more weeds. Prof Ma Zhifeng reminded growers that when D. oleracea is severe, it can spray 40% omethoate 1000 times or 50% parathion 1500 times on dry fruit and ground weeds.

Get a good five-point tube orchard in October
In October, late-maturing apple varieties matured, but the leaves were still undergoing photosynthesis after fruit harvesting, and the roots were still at the third peak of growth. Current orchard management is still the focus. How to manage the best, Ma Zhifeng, an expert on fruit mixing in the Yangling Vocational and Technical College, has provided scientific guidance for the majority of growers.
