Cherry post-harvest management
From fruit picking to defoliation, the nutrients produced by the leaves during this period of time are no longer used for fruit consumption, but rather for further differentiation and enrichment of flower buds, thick branches, tissue maturation, and accumulation of major nutrients. Therefore, good management during this period will not only increase tree nutrients, increase wintering ability and resistance to adverse environmental conditions, but also have a decisive effect on the fruitfulness and growth of the coming year. 1, adjust the amount of tree branches. After cherries are harvested, thinning, short and thin branches, whip sticks, and pests and branches must be removed or shortened in order to open the light path, enrich the branches, reduce unnecessary consumption, and facilitate the differentiation and enrichment of flower buds. Mature branches. 2, control of pests and diseases. Peach leafhopper, also known as swiftlet, is the main pest in the late growth period of cherry. It is the most intense in July and September. Yellow and white spots appear in the damaged peach leaves. When it is severe, the whole leaves are brown and fall off earlier, causing the tree vigor to weaken, affecting flowers, etc. Formed to reduce the output in the coming year. The precautionary measure is to spray 200 times Bordeaux mixture or 40% dimethoate emulsifiable concentrate 1000--1500 times once immediately after fruit harvesting. 3, scientific fertilization. From the end of May to the beginning of June, 50-1000kg of organic fertilizer is applied to the plant. If 1kg/plant of superphosphate is mixed in, the effect is better. Fertilization methods can be applied alternately radially and circularly, located just below the periphery of the canopy. The fertilization ditch should be shallow and deep inside to prevent excessive root breakage, followed by watering once. 4, foliar spray fertilizer. After the fruit is taken, a 0.5%--1% urea solution is sprayed every 10-15 days, and a 0.5% superphosphate solution is sprayed at the same time to increase the photosynthetic capacity of the leaves and increase the nutrition of the shoots.
