Planting watermelons on slopes, dry land and ladders is a good way for farmers to get rich. In order to capture the high yield and quality of watermelon, there are six taboos in fertilization:
First, avoid partial application of nitrogen fertilizer. If the watermelon is applied with nitrogen fertilizer, it is easy to cause a long length, affecting the fruit setting rate, reducing the number of melons and reducing the sweetness. In order to improve the yield and quality of watermelon, it is necessary to apply nitrogen, phosphorus and potassium fertilizers together, and apply organic fertilizers such as chicken, duck plague, cake fertilizer and grass ash.
Second, avoid applying chlorinated fertilizer. If the watermelon contains chlorinated fertilizer, it will affect the quality of the fruit and reduce the sweetness. Therefore, nitrogen fertilizer should be urea, ammonium sulfate, potassium fertilizer should be potassium sulfate, grass ash is appropriate, it is not appropriate to apply ammonium chloride and potassium chloride and other chlorinated fertilizer.
Third, avoid dry application of concentrated fertilizer. When the soil is dry, the application of concentrated fertilizer will cause the root cytoplasmic aqueous solution to permeate outward, causing the separation of the cytoplasmic wall, causing the watermelon vine leaves to lose water physiologically and wither until the plants die. Therefore, in the case of dry weather and low soil water content, irrigation or watering should be done first to moisten the soil before fertilization.
Fourth, avoid fertilizing in rainy days. The rainy weather has high humidity and high soil water content. At this time, fertilization and fertilizer are not only easy to lose, but also the vine leaves are long and the leaves are crisp and easy to induce pests and diseases.
Fifth, avoid near-plant root fertilization. With the elongation of the melon, the root system will gradually expand. If the root is fertilized, the fertilizer will not be fully absorbed and utilized. Therefore, the fertilization should be applied to the distant part of the plant from near to far according to the elongation of the melon, in order to facilitate the absorption of the root of the watermelon.
Sixth, avoid the topsoil fertilization. In summer, the temperature is high, and there are many thunderstorms. If the fertilizer is applied to the topsoil, not only will the fat be easily evaporated, but it will be lost by the rain. Fertilization should be carried out in the deep roots between the plant roots, and then cover the soil to improve fertilizer efficiency.
