Look at the types of vegetables to determine the type of fertilizer 1, leafy vegetables should try to use urea, ammonium bicarbonate, human fecal urine and other fast-acting nitrogen fertilizer. 2, rhizome vegetables to apply potassium chloride, grass ash and other fertilizers containing higher potassium. 3, fruits and vegetables, in addition to nitrogen fertilizer, phosphorus, potash fertilizer demand is also greater. Looking at the changes in the weather and setting the amount of fertilization When the temperature is high, the crops grow vigorously and the amount of fertilizer required is also large. At the same time, the high temperature is favorable for the decomposition and conversion of fertilizers. Therefore, appropriate temperature can be used for fertilization in suitable growing season, and low or no fertilization should be applied in cold weather and cold season. If fertilization is required, irrigation should be conducted first. See Fertilizer Type Fertilization Method For some volatile fertilizers, it is best to bury them in deep soil. Phosphorus and potassium fertilizers move slowly downward in the soil and can be uniformly applied to the tillage layer. For fertilizers that are easily soluble in water, they are better when applied to the field with irrigation water. Fertilizer can be sprayed on the leaves, but it is necessary to grasp the best spraying period and concentration. To see the amount of fertilizer given by the cultivation method, the amount of fertilizer needed by the protected vegetable is more than 1 times higher than that of the same kind of vegetable cultivated in open field. Such as open land leek, 2000 to 2500 kilograms of organic fertilizer can be applied per acre, while the use of yangzhou must use 4000 to 5000 kilograms of organic fertilizer to meet its growth needs.
