1.Kale fertiliser production 1000 kg of kale need pure nitrogen 2.0 kg, phosphorus pentoxide 0.72 kg, potassium oxide 2.2 kg; mu yield kale 3000 ~ 5000 kg, need pure nitrogen 6 ~ 10 kg, phosphorus pentoxide 2.2 ~ 3.6 kg, potassium oxide 6.6 ~ 11 kg. Before planting kale mu 2500 kg of organic fertiliser, phosphorus fertiliser 20 to 25 kg. When kale enters the rosette stage, the 1st fertiliser is carried out, and 36 kg of pure nitrogen and 3.3-5.5 kg of potassium oxide are applied per mu. Into the kale balling period, the 2nd fertiliser, mu Shi pure nitrogen 3 ~ 6 kg, potassium oxide 3.3 ~ 5.5 kg.
2.Pepper fertiliser production 1000 kg of pepper need pure nitrogen 5.2 kg, phosphorus pentoxide 1.1 kg, potassium oxide 6.5 kg. Mu production of bell peppers 4000 ~ 5000 kg, phosphorus fertiliser 30 ~ 40 kg. When squatting is over, the 1st spike of fruit grows to walnut size, the 1st fertiliser, mu of pure nitrogen 5 to 6 kg, potassium oxide 6 to 8 kg. When into the first spike of fruit (door pepper) is about to harvest, the second layer of fruit (pepper) and the third layer of fruit (four mother bucket) continue to expand and the third layer of fruit is falling fruit, for the peak of fertiliser requirements, should be reapplied the second fertiliser, mu of pure nitrogen 6 ~ 7 kg, potassium oxide 7 ~ 8 kg. Thereafter about half a month for the 3rd fertiliser, fertiliser with the 2nd. 15 ~ 20 days later, the 4th fertiliser, fertiliser with the 1st.
3.Cucumber fertiliser production 1000 cucumbers need pure nitrogen 2.6 kg, phosphorus pentoxide 1.5 kg, potassium oxide 3.5 kg mu yield cucumber 4000 ~ 5000 kg need pure nitrogen 10.4 ~ 13 kg, phosphorus pentoxide 6 ~ 15 kg, potassium oxide 14 ~ 15.7 kg. At the early stage of melon production, the first fertiliser should be applied 3-4kg of pure nitrogen and 4-6kg of potassium oxide. In the early stage of melon production, the 2nd fertiliser should be applied, 3~4kg of pure nitrogen and 5~6kg of potassium oxide. In the middle stage of melon growth,vertical gardening systems the 3rd fertiliser will be applied, 3~4kg of pure nitrogen and 5~6kg of potassium oxide. Before planting mu 5000 kg of organic fertiliser, phosphate fertiliser 40 to 50 kg.
4.Carrot fertiliser production 1000 kg carrot needs pure nitrogen 2.4 kg, phosphorus pentoxide 0.8 kg, potassium oxide 5.7 kg. Mu yield carrot 3000 ~ 4000 kg, need pure nitrogen 7.2 ~ 9.6 kg, phosphorus pentoxide 2.4 ~ 3.2 kg, potassium oxide 17.1 ~ 22.8 kg. Before sowing carrots, mu apply 2500 kg of organic fertiliser and 25-30 kg of phosphorus fertiliser. Entering the rosette stage, the 1st fertiliser is carried out, with mu applying 3～4 kg of pure nitrogen and 8～10 kg of potassium oxide. Flesh root growth period for the 2nd fertiliser, mu Shi pure nitrogen 4 ~ 5 kg, potassium oxide 8 ~ 12 kg.
5.Celery fertiliser production 1000kg celery need pure nitrogen 2.0kg, phosphorus pentoxide 0.93kg, potassium oxide 3.9kg. If you produce 4000-5000kg of celery per mu, you need 8-10kg of pure nitrogen, 3.7-4.6kg of phosphorus pentoxide and 15.6-19.5kg of potassium oxide. Before celery planting, apply 4000-5000kg of organic fertiliser and 25-35kg of phosphorus fertiliser per mu. When the plant enters the vigorous growth period, the 1st fertiliser is carried out, and 2.3kg of pure nitrogen and 5-6kg of potassium oxide are applied per mu. Half a month after the 2nd fertiliser, mu of pure nitrogen 3 ~ 4 kg, potassium oxide 5 ~ 7 kg. After half a month into the 3rd fertiliser, mu of pure nitrogen 3 kg, potassium oxide 5 to 6 kg.
6.Leek fertiliser production 1000 kg leeks need pure nitrogen 3.7 kg, 0.8 kg of phosphorus pentoxide, potassium oxide 3.1 kg. Mu 5000 kg of leeks need 18.5 kg of pure nitrogen, 4 kg of phosphorus pentoxide, potassium oxide 15.5 kg. Before leek planting mu 5000 kg of organic fertiliser, phosphate 30 kg, leek root planting more than ten days after the new roots have occurred, can be combined with watering for the first time fertiliser, mu of pure nitrogen 3 kg, 3 kg of potassium oxide. early September to early October, is the strongest period of leek assimilation function, should be combined with watering, every 10 to 15 days after a fertilizer, fertilizer with the amount of the first time, the second spring, you can start harvesting, can be harvested, the year 3 to 4 times, each time the phosphorus 0.8 kg, the phosphorus 0.8 kg, the phosphorus 0.1 kg. Harvesting 3 to 4 times throughout the year, after each harvest, when the new shoots grow to 3cm high, you can chase 1 time of fertiliser, the same amount of fertiliser as before.
