Pick all branches and hang vines: melons have many branches, and most varieties are mainly fruit-bearing melons, including purple vines and sun vines. Therefore, it is generally necessary to pick the heart when the seedlings grow to 4-5 true leaves to promote the growth of lateral branches. After the young melon sits down, the core is removed to promote the transport of nutrients to the young melon and promote the expansion of the young melon. The pruning method of melon can be carried out according to the habits of different varieties. Generally, muskmelon cultivated in greenhouse is pruned by single vine or double vine. Single vine pruning is to pick the heart when the main vine has 4-5 true leaves, leave a strong vine at the base and remove all other vines. Sun Man, who grew up in the 7th-11section of post-harvest melon, left 1-2 leaves in front of the melon for coring. When the vines grow to 25-30 leaves, they are also picked, and all the sun vines that do not bear melons are removed. Thin-skinned melons generally pick the heart when the seedlings grow to 5 true leaves, leaving 4 lateral vines. When the sun vine grows, it leaves flowers and melons on it. Leave 3-4 leaves to pick the core before the sun is full of melons. Generally, there are 4-6 melons per plant, and they are allowed to grow without pruning after sitting. Melons cultivated in greenhouses are generally cultivated with branches or vines. Double-vine pruning refers to selecting two robust sub-vines from 3-4 leaves of the main vine, and selecting flowers in the middle of 1 1- 12. When the stems and vines grow to 50-60 cm, the vines are tied with brackets or pulled with nylon ropes and hemp ropes to make the melons and vines climb up and grow.
