How to manage watermelon after planting seedlings with plastic film mulching

1. Film surface management. The film surface should always be kept pressed down firmly and tightly against the ground to maintain the effect of plastic film mulching. When the wind is strong, the film surface tends to loosen after being blown by the wind, so tread it down and press it firmly at any time. In addition, the film surface should remain tightly sealed, without leaking wind or air, especially around the planting holes, which must be sealed completely and tightly.
2. Seedling protection management. Spring has a lot of wind and strong winds, and sometimes low-temperature cold waves occur; before low-temperature frost arrives, take preventive measures such as covering the young seedlings with grass; underground pests occur early under plastic film mulching, so pesticide control work should be carried out in a timely manner; do a good job of thinning, final thinning and replanting of seedlings, and strive to achieve uniform, complete and strong seedlings.
