1. Select excellent varieties. Seedless or seedless melons are prone to flat melons and flat head melons; large melon varieties are prone to broad shoulder-skinned melons; thin and brittle varieties of fruit peels, and small fruit-type varieties are susceptible to split melons. Therefore, these varieties should be avoided.
2. Strengthen protection. Such as low temperature, drought, insufficient light, improved post-stage conditions, easy to form flat melon, gourd-shaped melon or big belly melon; if the climatic conditions in the early stage of fruit development are suitable, low temperature, dry in the late stage, it is often formed in the late stage of the mouth-shaped melon fruit Heavy rain or too much water will also cause cracking. In the flowering period, the melon period and the expansion period of watermelon, spray the strong melon and improve the nutrient supply of watermelon. At the same time, together with the new high-fat film, a protective film of polymer film is formed on the watermelon to insulate the moisturizing and anti-pathogenic bacteria.
3. Strengthen fertilizer and water management. In the early stage of melon expansion, the fertilizer and water are insufficient. In the later stage, the water and fertilizer conditions will be improved, and the big belly will be formed. The supply of water and fertilizer in the early stage will be sufficient, and the supply of water and fertilizer will not keep up, and the tip of the mouth will be formed. The local temperature difference of the fruit is too large, and local damage will also form a deformed melon. At the same time, the fertilizer in the early stage is insufficient, and the fertilizer and water in the later stage are easy to crack the melon; the land lacking calcium and magnesium deficiency is easy to crack the melon. Therefore, it is necessary to strengthen the management of fertilizer and water in the melon garden.
