Prevention and Control of split Watermelon in Spring
Watermelon fruit cracking can be divided into field fruit cracking and harvest fruit cracking. The cracking of fruit in the field is caused by the sudden change of soil conditions. For example, in a certain stage of fruit development, the soil moisture is low, the fruit development is blocked, and the soil moisture increases sharply in case of rain or pouring water, resulting in the rapid expansion and cracking of the fruit, which is generally the first to crack in the flower scar part. it is also believed that the fruit develops slowly in the early stage of fruit development, and then expands rapidly, which leads to fruit cracking. Fruit cracking is related to varieties. Varieties with thin skin and crisp texture are easy to crack fruit. Preventive measures: select varieties that are not easy to crack, adopt rain protection in greenhouse planting, and reasonable fertilizer and water management. Fruit cracking during harvest is caused by thin peel and harvest vibration. Experienced melon farmers think that the application of potassium fertilizer can improve pericarp toughness and harvest in the evening can reduce fruit cracking.
