How to manage apple trees during the fruiting period? What should be noted during the fruiting period of apple trees? We would also like experienced readers to help explain.Generally, the fruiting period of apple trees falls during Minor Heat and Major Heat, when temperatures are high and apples are prone to pests and diseases. Therefore, Zhongdiwang has compiled management methods for the fruiting period of apple trees, listed in detail below for readers' reference.
I. Regularly inspect bagged apples:
1. Every 7-10 days, regularly open fruit bags at different positions on the tree. If problems such as rotten fruit or sunscald are found, promptly take corresponding measures to solve them.
2. After wind, rain, or pesticide spraying, inspect the whole orchard to see whether the fruit has slipped out of the bag or the bag is stuck to the fruit surface, whether the ventilation holes are open, etc., and promptly re-bag, drain water, and loosen bags to prevent sunscald and black-red spot disease. If heavy rain or continuous overcast rain occurs, the two ventilation holes on the bag can be appropriately cut larger to facilitate drainage and ventilation and avoid disease occurrence.
II. Prune the apple trees:
1. Promptly remove useless sprouts sprouting from pruning and saw cuts and ring cuts on apple tree branches and trunks.
2. Clear out water sprouts in the inner canopy as well as excess upright branches on the upper side, ineffective branches on the lower part of the canopy, crossing branches in the middle, and crowded competing branches on the periphery.
3. For 4-5 year old fruit trees, pay attention to removing the non-lignified parts of upright, competing, and long branches to promote secondary shoots and short branches and cultivate fruiting branch groups.
4. For the secondary and tertiary secondary shoots sprouted from the previous pinching, leave 3-5 cm and pinch back hard to favor flower bud formation.
III. Supplement fertilizer to the fruit trees in time:
For topdressing apple trees, for early and mid-season ripening fruit, potassium fertilizer applied in furrows is better; for late-ripening and mid-late ripening fruit, phosphorus and potassium fertilizer is better. For example, for every 50 kg of fruit, apply 1 kg of potassium sulfate or 7-10 kg of plant ash. Combined with pesticide spraying, spray the leaves once every 15 days with 0.3%-0.5% premium potassium dihydrogen phosphate, multi-element liquid fertilizer, and growth regulators, etc.
IV. Watering the fruit trees:
1. During the fruiting period of apple trees, soil moisture should not be lower than 60% of field capacity. In May-June, if no watering has been done due to drought, watering must be done by every possible means.
2. During the fruiting period of apple trees, plant ash water can be sprayed 1-3 times, that is, use 5-6 kg of plant ash, add 100 kg of water, stir, and soak for about 15 hours, then filter out the residue to obtain plant ash water. Click to view >>Main components of plant ash
V. Pest and disease control during the fruiting period of apple trees:
During the apple fruiting period, it is necessary to prevent and control pests and diseases such as the second generation of the peach fruit moth, red and white spider mites, cicadas, golden leaf miner, early defoliation disease, black-red spot disease, and fruit rot disease.
