Abstract

The invention discloses a high-phosphorus and high-potassium liquid fertilizer and a preparation method thereof and belongs to the technical field of fertilizers. The high-phosphorus and high-potassium liquid fertilizer is prepared from the following raw materials in parts by weight: 40-50 parts of EDTA-2Na, 900-1,100 parts of potassium hydrogen phosphate, 150-200 parts of water-soluble ammonium polyphosphate, 60-80 parts of chelated medium trace elements containing vitamin B, 15-25 parts of glycerinum and 600-800 parts of water. Through technological control of the charging sequence and the reaction conditions, phosphorus and potassium can stably co-exist in a liquid phase, so that the solubility of potassium ion is increased, the utilization ratio of the high-phosphorus and high-potassium liquid fertilizer is effectively improved, and high phosphorus, high potassium and the medium trace elements can be simultaneously supplied.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a high-phosphorus and high-potassium liquid fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is an essential material support for promoting plant growth and increasing crop production, and it is also one of the important conditions for the development of agricultural production. China is one of the countries that consume a lot of agricultural fertilizers in the world. At present, the common fertilizers on the market are high-concentration solid fertilizers with relatively single components, such as urea and nitrophosphate fertilizers. These fertilizers can only provide a large amount of nitrogen, phosphorus, and potassium. Nutrient elements, almost do not contain medium elements and trace elements, so that the crops have low lodging resistance, resistance to diseases and insect pests, and crops are easy to reduce production. In addition, f...
