Compound fertilizer containing additive KNP

Abstract

The invention aims to provide a compound fertilizer containing an additive KNP, which can regulate the release rate of the compound fertilizer to synchronize the fertilizer absorbing rule of crops. The compound fertilizer containing the additive KNP consists of the following components in percentage by weight: 26 to 28 percent of compound fertilizer, 19 to 21 percent of the additive KNP, 0.01 to 0.03 percent of diethyl aminoethyl hexanoate raw powder and 51.98 to 55.98 percent of filling material. Preferably, the compound fertilizer consists of the following components in percentage by weight: 24 percent of compound fertilizer, 20 percent of the additive KNP, 0.02 percent of diethyl aminoethyl hexanoate raw powder and 55.98 percent of filling material. The additive KNP mainly comprises humic acid and amino acid, and the molecular formula of the diethyl aminoethyl hexanoate raw powder is C18H33NO8. The filling material is raw soil or other organic fertilizer or inorganic fertilizer except the compound fertilizer, phosphate fertilizer and potash fertilizer.

Description

1. Technical field [0001] The invention relates to a compound fertilizer composition, in particular to a compound fertilizer containing an additive KNP. 2. Background technology [0002] At present, the average utilization rate of compound fertilizers is low, the loss of nutrients is serious, and it is easy to cause pollution to groundwater and rivers and lakes; conventional compound fertilizers are generally not easy to control the release rate of each nutrient, so that the release rate is synchronized with the progress of the crops to absorb the compound fertilizer, so if One-time application of a large amount of compound fertilizer is likely to cause burnt seedlings at the seedling stage, and it is often difficult to do multiple topdressing due to the limitation of manpower and cultivation conditions, resulting in poor growth of crops due to lack of fertilizer. At present, the utilization rate of nitrogen, phosphorus, and potassium is low, not only because the rate of com...

Problems solved by technology

[0002] At present, the average utilization rate of compound fertilizers is low, the loss of nutrients is serious, and it is easy to cause pollution to groundwater and rivers and lakes; conventional compound fertilizers are generally not easy to control the release rate of each nutrient, so that the release rate is synchronized with the progress of the crops to absorb the compound fertilizer, so if One-time application of a large amount of compound fertilizer is likely to cause burnt seedlings at the seedling stage, and it is often difficult to apply fertilizer multiple times due to the limitation of manpower and cultivation conditions, resulting in poor growth of crops due to lack of fertilizer

At present, the utilization rate of nitrogen, phosphorus, and potassium is low, not only because the rate of compound fertilizer used in general chemical fertilizers is not easy to control, but also because of the difference in soil quality in different regions, so that the utilization rate of nitrogen, phosphorus, and potassium in compound fertilizers is also low. not exactly
