The melon with the first female flower of pumpkin is the main root melon. Generally, only 10% of the melon seedlings form the main root melon. Removing the main root melon is the basis for obtaining high yield. Be sure to remove the root melon early and keep 1-2 large melons.

Pumpkin has the advantage of top growth. When the first melon sits on the melon, the vegetative area of the plant is relatively small, and the nutritional components produced by photosynthesis are small. Therefore, the main root melon is small, with few seeds and small seeds, and the yield is low. Moreover, after the main root melon sits, the rear melon rarely sits, or the melon does not grow, so the main root melon must be removed as soon as possible. Melon with the second or third female flower.

The nutrition provided by the seedlings is limited, and only 1-2 melons can be left. It takes at least 45 days from sitting to ripening. Therefore, the melons before the beginning of autumn can mature after autumn, and the melons at the back of autumn can not mature after autumn. There are many small melons left on one seedling, and the grain size is small, and the yield also decreases.

The principle of keeping melons is to remove the root melons as early as possible, to ensure that one melon, at most two melons, and to prevent multiple melons. In rainy season, it is also necessary to promote early maturity and prevent epidemic diseases. Take the melons in the ridge to the ridge platform, and break the leaves on the melons to expose the melons, ventilate and light, and promote early maturity. The selected melons should be timely placed along the melons and cushioned melons, and be exposed to sunlight to avoid strong light burns.

After the young melon is expanded, turn the melon in the half mature stage. Because the shady side of the melon contacts the ground, and there are many kinds of bacteria in the soil, when the humidity is appropriate, the fruit will be infected at any time, and the shady and shady sides of the melon will be replaced. At the same time, the leaves on the melon will be broken to expose the melon, and the ventilation and light transmission will not only prevent the occurrence of shady decay and disease, but also promote the early maturity of shady melon seeds. Where conditions permit, grass can be placed under the melon to prevent the fruit from rotting.

When the melon grows to the size of an egg, pinch the main vine and keep about 20 leaves. When the planting area is small, you can not pinch the main vine. However, you should remove the water fork as soon as possible to promote the supply of nutrients to the melon and seeds, so that the melon seeds are full and free of shriveled seeds. It can be finished in one day by two people in one field. Be careful not to be too late to prevent too long vines from being difficult to distinguish and hard to beat, and large labor force. You can use a small shovel to shovel when you see the growth point of the main vine in the field, and then use the shovel to get soil to press the vine, break off the water branches, cut off the main root melon, and do not need to bend down. The yield can be increased by about 20%.
