When is the picking time for big cherries?

1. The picking time of big cherry is generally about 35 days after flowering to harvest early-maturing varieties, 40-45 days to harvest medium-maturing varieties, and 50-55 days to harvest late-maturing varieties.

two。 The picking time of big cherry is different in different varieties and regions, for example, the picking time of big cherry in Dalian is from the beginning of June to the end of the month, and the picking time of Yantai is from May to the end of June.

What should we pay attention to after picking big cherries?

1. Fertilizer and water management

Big cherries should be fertilized in time after fruit harvest. The common methods of postharvest topdressing are ditch application of mature manure, sprinkling of compound fertilizer and foliar spraying. Results each tree was generally treated with 30-50 kg or 2-3 kg of rotten bean cake or 1 kg of N, P and K compound fertilizer without chloride, and the soil was covered and irrigated in time after fertilization.

two。 Shaping and pruning

Summer pruning of big cherries should be carried out immediately after fruit harvest. The main technical measures include thinning, coring, twisting and pulling branches, etc., using summer pruning to weaken the competitive branches, adjust the ventilation and light transmission level in the crown, increase the amount of fruiting branches and nutrient reserve, prevent the fruit parts from moving out, and promote flower bud differentiation. The application of anti-corrosion film on tree-cutting wound can quickly form an anticorrosive film, seal the wound and heal quickly. Prevent virus invasion, prevent the spread of rot, prevent Rain Water pollution, prevent large wounds from drying and cracking.

3. Thinning branch

It is mainly carried out after fruit picking, and for some fruiting trees with closed crowns and poor ventilation conditions, the over-dense branches are mainly removed to solve the wind and light conditions in the crown, and the upright strong branches that seriously affect the wind and light conditions in the crown should be removed from the base. The peripheral backbone branches and perennial branches of the crown should also be removed from the base.

4. Pest control

For brown spot perforation and bacterial perforation, timely spraying pesticides with corresponding efficacy combined with new high-fat film can increase efficacy; prevention of gum disease can be combined with prevention and control of leaf diseases after fruit harvest, and should be sprayed to protect trees in the whole orchard. It can absorb solar ultraviolet disinfection and sterilization, inhibit the formation and transmission path of plant airborne virus, and improve plant immunity and health index. Pest control of big cherry: red and white spiders, peach leaf moth and red-necked longicorn beetle are common pests. Corresponding pesticides should be used in time, combined with spraying with new high-fat film, which can shield the sense of smell of pests, inhibit the replication of bacteria, reduce their drug resistance and dosage, and improve the effect of pesticides.

Picking big cherries at the right time has a certain effect on yield, quality, storability and so on. Because the harvest is early, the yield is low and the quality is poor; if harvested too late, the storability is reduced, and the fruit is overripe and fallen.
