First, the selection of varieties is dominated by early-maturing varieties. These varieties mature before the rainy season and can avoid cracking. Second, scientific irrigation in the fruit development period, to prevent the soil dry and wet, to control the soil moisture content. Keep the soil moisture at 60%-80% of the maximum soil water holding capacity. When drought occurs, it is necessary to use small water for pouring and flood water is strictly prohibited. After the fruit begins to color, the soil must not be too wet or too dry. Third, sheltered rain cultivation of open cherries, to build a shelter, but also in the rain, temporary cover with a plastic film, after the rain uncovered.
