Reasonable formula fertilization improves the utilization rate of fertilizer, reduces the amount of chemical fertilizer application, protects the farmland ecological environment, maintains the ecological balance, and increases the income of farmers. It plays an extremely important role. Different fertilization methods should be used for fields with different fertility:

First, the ingenious formula

1. High fertility field

The target output is more than 650 kg/mu, and 1000-1200 kg of organic fertilizer per mu is used as the base fertilizer. The recommended formula for single-fertilizer is: 11~13 kg of urea, 15~20 kg of calcium, and 8 kg of potassium sulfate. It is recommended to use ternary compound fertilizer (14:6:5), and apply 35~40 kg per mu.

2. Zhongfei Litian

The target output is 600 kg/mu, and the organic fertilizer is applied with 1200~1500 kg per mu as the base fertilizer. The recommended formula for single chemical fertilizer is: 13~15 kg of urea, 20~25 kg of calcium, and 8 kg of potassium sulfate. It is recommended to use ternary compound fertilizer (14:6:5) and apply 40~50 kg per mu.

3. Low fertility field

The target output is 550 kg/mu, and 1500~2000 kg of organic fertilizer per mu is used as the base fertilizer. The recommended formula for single chemical fertilizer is: 15~17 kg of urea, 25~30 kg of calcium, and 8 kg of potassium sulfate. It is recommended to use ternary compound fertilizer (14:6:5) and apply 50~55 kg per mu.

Second, rice high-yield formula fertilization method

Organic fertilizer is poured into the soil when plowing the field. 80~90% of the phosphorus and nitrogen fertilizers used as the intermediate fertilizer, and the remaining 10-20% of the nitrogen fertilizers are applied as the split fertilizer or panicle fertilizer, and the potassium fertilizer is applied in the middle growth period (about 45 days after planting); For the mixed fertilizer, the compound fertilizer is used as the middle layer fertilizer once; for the cold soaked zinc deficiency field, 1 kg of zinc sulfate per acre or 0.1~0.2% zinc sulfate solution per acre in the early growth period, spray 2~3 Times, interval 7 to 10 days once. Rice fertilization is a garlic field in the previous crop. After rice transplanting, nitrogen and phosphorus fertilizers are not recommended, and only potassium fertilizer is applied.
