First, the benefits of using fertilizer and organic fertilizer:
1. Use both land and land.
According to the test, the organic matter content of the plots where the fertilizers and organic fertilizers are used for 3 years is 0.08%-0.11% higher than that of the single-fertilizer, the ammoniated bacteria increase by 260%, the aerobic nitrogen-fixing bacteria increase by 119%, and the fiber-decomposing bacteria increase by 600. %.
2, high yield and high quality food.
The combination of chemical fertilizer and organic fertilizer can increase the yield by 10%-20% compared with single application of chemical fertilizer in the middle and low yield land, and the grain quality is also greatly improved.
3. Reduce fertilizer losses.
Tests show that the combination of chemical fertilizer and organic fertilizer can not only reduce soil redox potential, reduce ammonia nitrification, but also reduce nitrogen volatilization loss. Generally, the nitrogen fertilizer utilization rate can be increased by 10% to 15%.
Second, the requirements for the use of chemical fertilizers and organic fertilizers:
1. Grasp the application time.
The amount of organic fertilizer is large, and the effect is slow. It should be applied as early as possible. Generally, the base fertilizer should be applied once before sowing. The amount of chemical fertilizer is small, and the effect is quick. Generally, it should be applied about 7 days before the crop needs fertilizer.
2. Master the application method.
Organic fertilizer should be applied to the soil layer in combination with deep tillage. Nitrogen fertilizers used in combination with organic fertilizers should be used as base fertilizers or top dressings, while phosphate fertilizers can be used as base fertilizers along with organic fertilizers.
3. Control the amount of fertilization.
Fertilizers are used in combination with organic fertilizers, and their amounts can vary depending on the crop and soil fertility. Such as corn, in low-fertility soil, can apply 250-300 kg of organic fertilizer per acre, 25-30 kg of urea, 25 kg of compound fertilizer; in medium-fertile soil, 250 kg of organic fertilizer per acre, urea 20 ~ 25 kg, compound fertilizer 20 ~ 25 kg; in high-fertility soil, 200 kg of organic fertilizer per mu, 15 to 20 kg of urea, 20 to 25 kg of compound fertilizer.
