The application amount, fertilization period and application method.
Second, cotton soil nutrient status
According to the survey and test results of soil testing and fertilization conducted in recent years, the soil nutrient content of cultivated land showed a downward trend, and the general performance was lacking, and the degree was becoming heavier.
III. Fertilizer Status and Problems in Cotton Fields

3. The utilization rate of fertilizers is getting lower and lower, and the crop resistance is obviously weakened.
Fourth, cotton science fertilization
1. Master the reasonable amount and proportion of fertilization. The suitable ratio of N, P and K in the city is 1:0.4:0.9.
2. Grasp the appropriate period of application of various fertilizers. P fertilizer was used as base fertilizer, N fertilizer was applied as top dressing, and K fertilizer could be used as base fertilizer, bud fertilizer and flower bell fertilizer three times.
3. Reasonable fertilization method. The first is appropriate deepening, the second is the application of organic fertilizer and inorganic fertilizer, the third is to do a good job outside the root fertilizer.
4. Apply organic manure and micro-fertilizer, apply 2,000 pounds of farmyard fertilizer per mu of cotton field, and apply boron fertilizer.
