The yield and quality of watermelon are highly related to fertilization, especially the sweetness of watermelon. Whether fertilization is appropriate is a decisive factor. Production practice proves that watermelon fertilization should be done six:
1. It is not advisable to apply chlorinated fertilizer. Watermelon contains chlorinated fertilizers such as ammonium chloride, potassium chloride, etc., chloride ions enter the plant body, will reduce the sugar content of watermelon, so that the taste of watermelon is sour, the quality is worse. Fertilizers such as ammonium sulfate, potassium sulfate, and potassium dihydrogen phosphate should be applied.
2. It is not advisable to apply nitrogen fertilizer. Partial application of nitrogen fertilizer, excessive nitrogen in the plant, the sugar contained in the pulp will be reduced, the quality is reduced, the meat is tender and tender, the color is light and thick, and the taste is sour. At the same time, partial application of nitrogen fertilizer is also likely to cause vine leaves to grow wild and affect the rate of results. Therefore, nitrogen, phosphorus and potassium should be used together to promote the healthy growth of the melon and improve the quality of the fruit. Generally, 15 to 20 kg of urea per acre, 60 to 80 kg of superphosphate or 20 to 25 kg of diammonium phosphate and 20 kg of potassium sulfate. If the special compound fertilizer for watermelon is applied, the effect is better.
3. It is not advisable to apply concentrated fertilizer when the soil is dry. When the soil is dry, the application of concentrated fertilizer will cause the cytoplasmic aqueous solution of the watermelon root to penetrate outward, causing the separation of the cytoplasmic wall, which may cause the physiological loss of water from the watermelon vine leaves and die. At this time, low-concentration fertilizer should be applied, and fertilization should be carried out after watering first, or fertilization and watering should be carried out simultaneously.
4. It is not advisable to fertilize on a rainy day. On a rainy day, the air humidity is high and the soil moisture content is high. At this time, not only the fertilizer is easily lost, but also the branches and leaves are long, making the leaves and vines crisp, which is not conducive to sitting on the melon and easy to induce watermelon disease.
5. It is not advisable to fertilize near the root of watermelon. After the melon vines are stretched, the root system also expands to the distant place. At this time, the near-root fertilization is not fully absorbed and utilized. At the same time, it is too close to the roots to fertilize and easily burn roots.
6. It is not advisable to apply surface fertilizer. If the fertilizer is applied to the surface of the soil, not only the fat is easily lost, but also the cucumber is easy to burn. Watermelon topdressing should be applied deep in the hole and covered with soil after application.
