1. Cotton: When cotton is controlled release fertilizer, the leaves of the plants at the seedling stage are thick; in the flowering and boll stage, the growth is vigorous, there are many buds, and there are many bells and bells; the flowering and bolling period is long and the yield increase effect is obvious. Scientific use: 15 cm from the cotton seedlings can be planted or applied in a hole, covering the soil after application; the amount of application varies depending on the yield and fertility, generally 667 square meters of application of 35 to 40 kg.
2. Peanuts: Peanuts use controlled-release fertilizers, and the leaves have a dark green color and high average plant weight. The number of pods is large. The grain is full, the pods mature earlier, and the root system is more developed. The number of fruit per plant, the fruit weight per plant, and the kernel The weight has been significantly improved and production has been significantly improved. At the same time, the protein content of peanuts was increased, and the fat content, soluble sugar content, vitamin C content, and amino acid content of peanut seeds were also improved to varying degrees, and the quality of peanuts was also significantly improved. Scientific use: Use low-nitrogen, high-phosphorus and high-potassium formulations as well. As a base fertilizer trench application, the application amount varies depending on the yield and the soil strength. Generally, the application amount of 667 square meters is 20-40 kg.
