One bogey single application of large amounts of nitrogen fertilizer. The fertilization of watermelon should pay special attention to the combination of nitrogen, phosphorus and potassium. If a single application of a large amount of nitrogen fertilizer, the plants are extremely prone to growth, which is not conducive to flowering melon and fruit development.
Second avoid application of chlorine fertilizer. Watermelon is a chlorine-tolerant crop, and the application of chlorine-containing fertilizer will affect the accumulation of sugar and make the melon taste lighter.
Three bogey top layer fertilization. Pay attention to deep application of watermelon dressing, timely covering after application, especially nitrogen fertilizer, if the table is applied, nitrogen is easily volatilized to produce ammonia gas, harm the leaves, and reduce fertilizer efficiency.
Four bogey rainy days fertilization. In the rainy days, the air has high humidity and high soil moisture. At this time, fertilizer is not only easy to lose fertilizer, but also can easily cause watermelon to grow.
Five bogey fertilization sites too close to the root. The fertilization site of watermelon is generally required to be about 10cm from the main root, and it is easy to burn roots if it is too close.
Sixth, avoid topdressing when it is dry. When the weather is dry and the soil moisture content is low, applying chemical fertilizer at this time will make the cytoplasmic solution of the root cells penetrate outward, causing the plant to be physiologically dry and die.
