Compound fertilizer is suitable as base fertilizer. Application method of base fertilizer: The granule compound fertilizer containing various nutrients of nitrogen, phosphorus and potassium is applied to a certain depth of soil when cultivating land before sowing. The depth of fertilization varies from crop to crop, the depth of fertilization of food and vegetables is generally 20 cm, and the depth of fertilization of fruit trees is 30-40 cm. Only when the compound fertilizer is applied to a certain depth can the demand for nutrients in the middle and late crops be supplied. The compound fertilizer used as the base fertilizer applies all the phosphorus and most of the potassium required for the growth period of the crop. Nitrogen is too active, and only part of it can be applied to the base fertilizer through compound fertilizer. At least half of the nitrogen should be applied as top dressing in the form of elemental nitrogen fertilizer during the vigorous growth period of the crop. Therefore, the compound fertilizer is suitable for the base fertilizer, and the nitrogen ratio cannot be too high. The nutrient ratio of nitrogen, phosphorus and potassium in any compound fertilizer is fixed. The calculation of the amount of base fertilizer is based on the content of phosphorus or potassium, and half of the nitrogen fertilizer needs to be applied in the middle and late stages. Compound fertilizers are generally not suitable for top dressing or water flushing. Among them, the phosphate fertilizer, even if it is fully water-soluble, rarely moves downward on the soil surface, and the crop root system is difficult to use. Although the vegetable farmers in Guangdong are accustomed to importing the general-purpose 45% (15%-15%-15%) compound fertilizer into water, the leafy vegetables have obvious fertilizer efficiency, but their nutrient utilization rate is low, not only waste of fertilizer. The cost is not cost effective and needs improvement. Disclaimer: Some articles on this website are transferred from the Internet.
