The latest course on post-planting management techniques of muskmelon

Melon is a very popular fruit in summer. Muskmelon has strong growth ability and has a large wild distribution area. But now with the expansion of market demand, there is also a large artificial cultivation area. Management is very important when planting melons, especially after planting. So how to manage melons after planting? The following editor brings you the management technology after melon planting, let's have a look!

1. Temperature management

The temperature requirement of muskmelon is relatively high after planting, and the slow seedling stage of muskmelon is generally about a week. During this period, the greenhouse should be closed and the temperature should be increased. In the first 6 days, the daytime temperature of the greenhouse should be controlled at about 32 degrees, the highest can not exceed 35 degrees, if it exceeds 35 degrees, then it should be ventilated and cooled in time. The temperature should also be kept at about 20 degrees at night, and the wind will begin to be heard a week later. When the stem vine grows, the temperature should be reduced to 27 degrees, and the temperature during pollination should be cultivated, which can be kept at about 24 degrees. In short, the temperature should be adjusted according to different growth periods of melons, and it should be noted that the whole growth period should be kept above 15 degrees.

2. Rational watering

After planting, the planting water should be poured thoroughly to ensure the survival of the seedlings. After survival into the seedling stage, it is necessary to appropriately reduce the amount of water to avoid excessive water leading to excessive growth of seedlings. Then during the fruit expansion period, it is necessary to water more to meet the water demand of fruit growth. Watering time should be carried out when the fruit reaches the size of an egg. After the fruit expansion stops, the amount of water should be reduced, and then no more watering should be allowed 10 days before harvest. Watering should not be carried out at high temperature at noon, mainly with small water to prevent stagnant water from causing seedling death.

3. Scientific fertilization

Muskmelon soil preparation before planting, should be combined with fertilization, apply sufficient base fertilizer. Then topdressing about twice in the melon growth period, according to the muskmelon plant growth to make a reasonable adjustment. Compound fertilizer is the main fertilizer, and appropriate amount of ammonium calcium nitrate fertilizer can be applied with Dinggua water at one time, and the amount of ammonium calcium nitrate per mu is controlled at about 12kg. Then, when watering the fruit during the expansion period, combined with topdressing liquid fertilizer, the dosage was controlled at about 20kg. And we can also properly spray foliar fertilizer, about once a week, about 3 times. It should be noted that when topdressing, do not apply chlorine-containing fertilizer to avoid the impact on muskmelon.

4. Ventilation management

In the initial stage of planting, because the temperature difference between inside and outside the shed is relatively large. Therefore, when we are in ventilation, we should pay attention not to excessive ventilation, just open a central vent. In windy weather, open the leeward outlet, otherwise open the windward outlet. Generally speaking, the ventilation rate should be adjusted reasonably according to the weather change. In the middle and late stage of muskmelon, the growth direction of muskmelon changed to reproductive growth and entered the peak growth period. It is necessary to replenish carbon dioxide in time, improve fruit setting rate and promote fruit expansion, so it is necessary to increase ventilation and ventilation every day and night. The ventilation time in the morning can be appropriately delayed to increase the temperature in the greenhouse and enhance photosynthesis. The ventilation rate can be reduced appropriately at night, in which the plant respiration consumes too much nutrition.

The above is a brief introduction to the management technology of muskmelon after planting. The management of melons after planting is very important, which is closely related to the quality and yield of fruits, so we must pay more attention to it. That's all for today's introduction.
