Water Management techniques of Watermelon in Summer and Autumn

During summer and autumn, high temperature and drought are often encountered, and plant transpiration is large, especially in fruit setting and fruit expansion period, which is very sensitive to water. Lack of water will cause ovary shedding, low yield and poor quality. When drought and lack of water, the young leaves at the apex of the seedlings become smaller, the leaf color becomes gray, and the leaves wilt at noon. Lack of water in the early stage is also easy to induce viral disease and lose the ability to set fruit. When the early temperature is high, watering should be carried out in the morning and evening, the amount of water should be 5 cm away from the ridge surface, the excess should be eliminated immediately, keep the border surface dry, do not flood irrigation. After entering the fruit expansion period, the temperature is getting lower and lower, watering should be carried out around noon, and small water can be watered frequently.
