Matters needing attention in planting watermelon

Watermelon must be a fruit that everyone is very familiar with. With the development of agriculture in our country, watermelon can be planted almost at any time and anywhere. However, planting watermelon is not so simple, and there are different management methods at each stage of watermelon growth. Especially in the colonization, there are some precautions that need everyone's attention. The following small series brings you the precautions when planting watermelon. Let's have a look together!

1. Before planting

Before watermelon planting, we should select the land and then do a good job of soil preparation. When soil preparation, deep ploughing and intertillage should be carried out together with basal fertilizer. Base fertilizer can be decomposed farm manure or poultry manure, but no matter what kind of fertilizer, it needs to be fully decomposed before application. Because the undecomposed fertilizer will produce a lot of heat, the temperature is too high easy to burn seedlings, affecting growth. And in the fertilizer also appropriate to add potassium sulfate, urea and various trace elements. Before and after the Qingming Festival in sunny days to do a good job in the field, easy to later management harvest. A week before planting, we should cover the plastic film, buckle the greenhouse, improve the surface temperature, and promote seed germination.

2. When planting

First, we should select disease-free, harmless, plump and high-yield seeds, and then do a good job of seed treatment. After selecting seeds, the seeds are exposed to the sun, which not only can disinfect and sterilize, but also can improve the germination rate of seeds. Sun for about 3 hours a day for 3 days. Then put the dried seeds in warm water of about 50 degrees for 5-7 hours, stir constantly, remove the mucus on the surface of the seeds, and improve the germination rate. Soak seeds and then use trisodium phosphate to soak for half an hour to enhance the disease resistance of seed plants. Then wrap it with damp cloth and put it at a temperature of about 30 degrees to germinate, pay attention to the temperature, not high or low. When the seeds appear after the embryo in the Qingming Festival, the surface at about 15 degrees when the sunny planting.

3. After planting

rosette stage

After planting, when the seedlings grow to about 5 leaves and begin to creep, it is the watermelon's cluster stage. Watermelon cluster stage is about half a month, after planting 2-3 days can not be ventilated, promote seedlings slow seedlings. After successful slow seedling, proper ventilation should be carried out, the temperature and humidity of the greenhouse should be controlled, the permeability should be improved, and the illumination should be enhanced. Properly inhibit the growth of watermelon, improve the stress resistance of watermelon, ensure robust growth, and achieve high yield and high quality.

seating stage

Under normal management, watermelon will gradually enter the melon setting period at the end of April after experiencing the watermelon cluster period. The temperature around the melon setting period has gradually picked up, and the anti-freezing work can be stopped. Watermelon plant roots and stems and leaves at the melon setting stage are very strong in growth ability, and it is very easy to overgrow if it is slightly mismanaged. If it is not treated in time, it will seriously hinder the flowering and fruiting, resulting in a decrease in fruit setting rate. Therefore, it is necessary to strengthen ventilation management during the watermelon period, cover the film at night, improve the proportion of nutrients, promote the nutrient absorption of watermelon plants, and improve the fruit setting rate.

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