Key points of management after grafting of muskmelon

Muskmelon can be sown and planted directly, but in recent years, continuous cropping has led to more and more serious soil-borne diseases, which seriously affected the yield and quality of muskmelon. Let's get to know it with the editor.

1. Control temperature

In 1-3 days after melon grafting, the indoor temperature should be strictly controlled, the temperature should be controlled between 23-25 degrees during the day and 20-22 degrees at night. One week after grafting, the temperature should be controlled between 23-24 degrees in daytime and 15-18 degrees at night, which is beneficial to the wound healing of grafted seedlings and the recovery of seedling growth as soon as possible after survival. In order to create a microclimate conducive to the growth of grafted seedlings, a small plastic arch shed can be added to the border, which can be covered during the day and at night to keep warm and control the temperature.

2. Control humidity

The seedling bed should be watered before grafting to increase soil and air humidity, which is conducive to the survival of grafted seedlings. The greenhouse should be sealed 2-3 days after grafting, so that the air humidity in the greenhouse should be kept between 90% and 100%, which is conducive to the healing of grafted wounds. After that, it is necessary to gradually increase the ventilation volume and ventilation time inside and outside the greenhouse, and return to normal management a week later.

3. Prevent the glare

In order to prevent the phenomenon of wilting of the grafted seedlings, the grafted seedlings need to be shaded out within 3 days after grafting to avoid direct sunlight, so the grass should be put down completely within 3 days of grafting, and the grass should be exposed every other after 3 days. Receive the light. With the time in figure 1, the number of unveiled films gradually increased, and after 10 days, all the grass was removed and entered the normal management. In addition, pay attention to shading time can not be too late, so as not to cause grafted seedlings thin and slender.

4. Prevention and control of diseases

Because the grafted melon seedlings have wounds and are in a high-temperature and high-humidity environment, they are very prone to diseases, so it is necessary to gather the seedling bed to spray water and chlorothalonil at the same time in the process of wound healing. this can effectively prevent the occurrence of melon seedling collapse and root rot.
