Pruning is an important technical measure for melon management and the key to success. Because the growth of melon main vines is weak, the growth of side vines is very strong, and the thin-skinned melons are mainly based on the results of vines and sun vines. In order to regulate the growth of melon stalks, techniques such as topping, pruning and snoring are often used in production. Control the vegetative growth of stems and vines to promote early melon and early maturity. The production of the melon farmers can be carried out by the following three methods.
Double vine pruning is suitable for cultivation in greenhouses and greenhouses. The main method is: the main vine leaves from one heart to three leaves and one heart, the two cockroaches are hanged in the lower part, one melon is kept on each vine, and two side branches (sun vine) are selected in front of the melon. Sun Man left three leaves to pick the heart, ensuring an average of 7 to 9 functional leaves to promote fruit development. A maximum of 4 melons can be left on each sub-branche, and the whole plant can leave 8 melons.
The three-vine pruning is suitable for the open field and the protected area. The main method is: the main stem has three leaves from one heart to four leaves and one heart, and each branch leaves three healthy vines. The first vine can leave a melon at the third leaf, and the second vine is in the second. Leave the melon at the leaf, and the third main vine can leave the melon at the first leaf. There are 3 to 4 Sun vines on each vine, and 3 leaves are left on each vine, and the whole plant is left with 3 melons. The fruit is mature and listed. There are more than 50 leaves in the whole plant, and there are 17 to 20 functional leaves per melon, which ensures that the photosynthetic products of the leaves can meet the accumulation of expanded melon and sugar, and promote the normal growth and development of the fruit.
Four vines are suitable for use in open fields and protected areas without hanging vines. The main features are the same as three vines. The method is as follows: the main stem has four leaves and one heart to five leaves and one heart, and each of the leaves leaves four healthy vines. The first vine can leave one melon at the fourth leaf, and the second one is in the third. Leave the melon at the leaf, the third main vine can leave the melon at the second leaf, and the fourth vine leaves the melon at the first leaf. Leave 3 to 4 sun vines on each vine, and leave 3 leaves on each vine to pick the heart. The whole plant leaves 4 melons.
Precautions Pruning should be carried out after the evaporation of the dew on the sunny day, in order to facilitate the healing of the wound as soon as possible to prevent infection. It is best to use scissors for the pruning, and prepare a damp towel soaked with 75% chlorothalonil 200 times solution, and cut a pair of scissors to prevent cross infection.
