Field management. 7-10 days after planting, follow the application of thin organic fertilizer and plant electronic fertilizer, and pay attention to prevent wetting the melon leaves when fertilizing. After the main vine is topped, apply a small amount of compound fertilizer at a distance of 0.3 m from the root. After each harvest, the rare and quick-acting nitrogen fertilizer is poured to promote the germination of the branches. When 8-10 leaves are removed, the top buds are removed to promote the vines. When the side vines are 0.8-1 meters long, the top tips can be harvested.
