Several main vegetable formula fertilization techniques
1.

Before the sowing of carrots, 2500 kg of organic fertilizer and 25-30 kg of phosphate fertilizer were applied. Enter the rosette period, carry out the first top dressing, apply 3 to 4 kg of pure nitrogen and 8 to 10 kg of potassium oxide. In the succulent root growth period, the second top dressing is carried out, and 4-5 kg ​​of pure nitrogen and 8-12 kg of potassium oxide are applied per mu.

Before the celery is planted, the application of organic fertilizer is 4000-5000 kg and the phosphate fertilizer is 25-35 kg. The plant enters a vigorous growth period and carries out the first top dressing. The application of pure nitrogen is 2.3 kg and the potassium oxide is 5-6 kg. After half a month, the second top dressing was carried out, and the pure nitrogen was 3 to 4 kg and the potassium oxide was 5 to 7 kg. After half a month into the third top dressing, the application of pure nitrogen 3 kg, potassium oxide 5 ~ 6 kg.
6. Fertilization of amaranth The production of 1000 kg of leek requires 3.7 kg of pure nitrogen, 0.8 kg of phosphorus pentoxide, and 3.1 kg of potassium oxide. 5000 kilograms of amaranth per mu requires 18.5 kilograms of pure nitrogen, 4 kilograms of phosphorus pentoxide, and 15.5 kilograms of potassium oxide. Before the planting of leeks, 5,000 kg of organic fertilizer and 30 kg of phosphate fertilizer were applied. After 10 days of planting of leeks, new roots have already occurred. The first top dressing can be combined with watering, and 3 kg of pure nitrogen and 3 kg of potassium oxide are applied per mu. From the beginning of September to the beginning of October, it is the strongest period of assimilation function of amaranth. It should be combined with watering, and the fertilizer should be chased once every 10 to 15 days. The amount of fertilizer applied is the same as the first time.
