Matters needing attention when planting the latest watermelon

Watermelon must be a kind of fruit that everyone is very familiar with. With the development of agriculture in our country, watermelon can be planted at almost any time and any place. However, growing watermelons is not so simple. There are different management methods at each growth stage of watermelons. In particular, there are some points for attention when planting. The following editor brings you some points for attention when planting watermelons. Let's take a look at them.

1. Before planting

It is necessary to select a good site before planting watermelons and then do a good job in soil preparation, turning deep into ploughing during soil preparation, combined with base fertilizer. Base fertilizer can use rotten farm manure or poultry manure, but no matter which fertilizer it is, it needs to be fully ripened before it is applied. Because the immature fertilizer will produce a great deal of heat, the high temperature is easy to burn the seedlings and affect the growth. And potassium sulfate, urea and various trace elements should be added to the fertilizer. Make the field beds in sunny days before and after Ching Ming Festival, so as to facilitate the later management of harvest. A week before planting, it is necessary to cover the plastic film, buckle the greenhouse, raise the surface temperature and promote seed germination.

2. When planting

First of all, we should choose seeds that are disease-free, harmless, full and sufficient and with high yield, and then do a good job of seed treatment. After selecting the seeds, exposing the seeds to the sun can not only disinfect and sterilize, but also improve the germination rate of the seeds. Bask in the sun for about 3 hours a day for 3 days. Then soak the sun-dried seeds in warm water of about 50 degrees for 5-7 hours, stirring constantly to remove mucus from the seed surface and improve the germination rate. Soak the seeds with trisodium phosphate for half an hour to enhance the disease resistance of the seeds. Then wrap it with a wet cloth and sprout at a temperature of about 30 degrees. Pay attention to the temperature, not suddenly high or low. When the seeds appear germ before and after Ching Ming Festival, when the surface is about 15 degrees, the sunny day colonization.

3. After planting

Tuanggu stage

After planting, when the seedlings grow to about 5 leaves and begin to crawl, it is the rosette stage of watermelon. Watermelon rosette period is about half a month, 2-3 days after planting can not be ventilated to promote slow seedling. After successfully slowing down the seedlings, it is necessary to properly ventilate, control the temperature and humidity of the greenhouse, improve the permeability and enhance the light. Properly inhibit the growth of watermelon, improve the stress resistance of watermelon, ensure robust growth, and achieve the goal of high yield and high quality.

Melon setting period

Under normal management, the watermelon rosette period will gradually enter the watermelon rosette period at the end of April. The temperature around the melon planting period has gradually picked up, and the work of preventing frost damage can be stopped. The growth ability of roots and stems and leaves of watermelon plants in the melon setting stage is very strong, and it is very easy to grow if it is slightly mismanaged. If it is not dealt with in time, it will seriously hinder flowering and fruit, resulting in a decline in fruit setting rate. Therefore, in the melon setting period, it is necessary to strengthen ventilation management, cover the film at night, increase the proportion of nutrition, promote the nutrition absorption of watermelon plants, and improve the fruit setting rate.

The above is a brief introduction of the matters needing attention before and after watermelon planting, watermelon planting has a very specific process, each process needs to be well managed. Management at the time of planting is very important, because the quality of management at this time will directly determine the growth and yield of the watermelon plant, so we must pay more attention to it.
