First, it is necessary to pay attention to picking the hearts before the end of September, for all uncapped shoots, remove all the delicate parts that have not yet been lignified, so that the nutrients flowing into the growing points will accumulate in the wooded tissues and promote leaf hypertrophy. , Photosynthetic efficiency, shoots high maturity, bud eyes full. Second, we must pay attention to thinning and re-absorption. We need to eliminate all kinds of long branches and dense branches that need to be cut during winter cutting to reduce the amount of winter pruning and nutrient consumption and improve the nutrient reserve of the tree. Third, we must pay attention to deep-turning the tree plate should be deep from the expansion of the outer edge of planting, increase organic fertilizer, curing soil. In general, one plant can be divided into two or four years, with a depth of 60-80 cm to deepen the distribution layer of the root system, improve the permeability of the soil, help to maintain water and fertilizer, and enhance the ability of the roots to absorb water and nutrients. Fourth, pay attention to the autumn fertilizer is a foliar fertilizer: in mid-August to mid-September, spray 2-3 times 0.3-0.5 kg of superphosphate and 6% of the ash leaching liquid; Second, the best soil fertilization in September, The strain applies 100-150 kilograms of ripening fertilizer to the circle, and it is better to add some ammonia and nitrogen fertilizer. Fifth, we must pay attention to Qiuqiu autumn fruit plots for the autumn, we must quickly clear the channels, as soon as possible to remove water, the upper surface of the fruit tree root neck open, accelerate soil ventilation, prompting the roots to restore normal vitality as soon as possible. Six, pay attention to protect the forest. In August once sprayed Bordeaux ferrous sulfate solution, the role of killing bacteria. The proportion of ferrous sulfate Bordeaux mixture: 3 kg of ferrous phosphate, 3 kg of quicklime, 100 kg of water, 30 kg of ferrous sulfate dissolved in water, made of ferrous sulfate solution, and a small amount of water extracted from the remaining 70 kg of water Dissolve the quicklime, and finally slowly pour the ferrous sulfate solution into the milk of lime.
