Big cherry science management anti-split fruit
1. Select anti-split fruit varieties. At present, large cherry varieties that are completely resistant to cracking have not been found, but the number and degree of fruit cracking vary from species to species. Such as large purple, crystal, bin-ku and other varieties, because of its low skin strength, large and large pores, strong water absorption, heavy cracking; Labins, Summit and other varieties are light fruit.
2. Maintain the relative stability of the soil. Cherry cracked fruit is closely related to the uneven distribution of soil moisture content. If the soil is in a state of water shortage for a long time, the fruit will be cracked when it is suddenly rained; if the soil moisture remains relatively saturated and stable, even if it suddenly rains, the fruit will be lighter.
3. Rational fertilization. Before the flowering, young fruit stage and fruit expansion period of cherry, spray the strong fruit and improve the water absorption and fertilizer absorption, increase the fruit yield and quality, reduce the fruit drop rate, and reduce the incidence of cracked fruit, stiff fruit and deformed fruit. Spraying a new high-lipid film solution every 7 days before fruit harvesting can reduce the rate of fruit cracking.
4, built a shelter. Before the fruit begins to color and the rainy season arrives, the plastic film is built to cover the rain shed, resulting in a rain-free environment and effective prevention of cracking.
