Do a good job of pruning melon

Pruning and topping is an important technical measure for melon management, and it is the key to the success or failure of cultivation. Because the melon main vine grows weakly, the side vine grows very vigorously, and the thin-skinned melon is generally dominated by vines and sun vines. To regulate the growth of melon stem vines, topping, pruning, pruning, etc. Technology to control the vegetative growth of vines and promote early fruiting and early maturity. Production farmers can take the following three methods to pruning:

First, Shuangman pruning

Suitable for greenhouse and greenhouse melon hanging vine cultivation. The main method is: when the main vine leaves two-hearted to three leaves one-hearted, they are sharp, and two strong vines are suspended in the lower part, each melon is left on each vine, and two side branches (sun vines) are selected before the vine. Three sun leaves were left on the vines to ensure that there were an average of 7-9 functional leaves to promote fruit development. A maximum of 4 melons can be left on each seed vine, and 8 melons can be left on the whole plant.

Second and third vine pruning

Suitable for open and protected cultivation without hanging vines. The main method is: the main stem has three leaves and one heart to four leaves and one heart is sharp, each plant leaves three strong vines, the first vine can leave a melon on the third leaf, and the second vine on the second Leave melon at the leaves, the third main vine can leave melon at the first leaves. There are 3 to 4 sun vines on each vine, 3 leaves on each vine, and then topping, and 3 melons are left on the whole plant. The fruits are mature and concentrated on the market. The whole plant has more than 50 leaves, with an average of 17-20 functional leaves per melon, ensuring that the photosynthetic products of the leaves can meet the expansion of the melon and sugar, and promote the normal growth and development of the fruit.

Three or four vines

It is suitable for uncultivated vine cultivation in open field and protected field. The method is: the main stem has four leaves and one heart to five leaves and one heart. It is sharp, and each plant leaves four strong vines. The first vine can leave a melon on the fourth leaf, and the second vine on the third. Leave melon at the leaves, the third main vine can leave melon at the second leaf, and the fourth vine at the first leaf. Leave 3 to 4 sun vines on each vine, leave 3 leaves on each vine, and harvest the toppings. Leave 4 melon on the whole plant.

Note: The pruning should be carried out after the dew evaporates on sunny days, in order to help the wound heal as soon as possible and prevent infection. For pruning, it is best to use scissors, and prepare a moistened towel soaked with 200% solution of 75% chlorothalonil, and cut a tree and wipe the scissors once to prevent cross infection.
