Rice fertilization should be rationally formulated according to different fertility fields to improve fertilizer utilization and reduce farmland costs.
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
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 applied once for the middle layer fertilizer; for the cold soaked zinc deficiency field, 1 kg of zinc sulphate per acre or 2~3 times with 0.1~0.2% zinc sulphate solution per acre in the pre-growth stage , interval 7 to 10 days once. The former crop is a field of garlic. After transplanting rice, nitrogen and phosphorus fertilizers are not recommended, and only potassium fertilizer is applied.
