Abstract

The invention provides a balanced type liquid water-soluble fertilizer. The balanced type liquid water-soluble fertilizer contains a nitrogen solution, water-soluble ammonium polyphosphate, water-soluble potassium polyphosphate and potassium chloride and is prepared from, by weight, 390-410 parts of the nitrogen solution, 150-180 parts of the water-soluble ammonium polyphosphate, 200-240 parts of water-soluble potassium polyphosphate, 50-100 parts of potassium chloride, 30-40 parts of chelated-state complex trace elements, 20-30 parts of a surface active agent and 430-550 parts of water. The liquid water-soluble fertilizer is a high-concentration liquid water-soluble fertilizer, N is greater than or equal to 170 g/L, P2O5 is greater than or equal to 170 g/L, K2O is greater than or equal to 170 g/L, and the trace elements are greater than or equal to 5 g/L. The nitrogen utilization rate is 80-82.8%, the potassium utilization rate is 80-82.6%, and the phosphorus utilization rate is 70-73%. The yield increasing rates of the fertilizer used for grapes, tomatoes and melons are 23-24.1%, 18-19.5% and 25-26.4% respectively.

Description

technical field [0001] The invention relates to a balanced liquid water-soluble fertilizer and a production method thereof, belonging to the technical field of liquid water-soluble fertilizers. Background technique [0002] Liquid fertilizer needs to be applied with water, which can better promote nutrient absorption, thereby improving fertilizer utilization efficiency. [0003] Compared with solid fertilizers, liquid fertilizers have the advantages of low production cost, little or even no pollution in the production process, evenly mixed fertilizer components, and consistent quality. In addition, the formula of liquid fertilizer is easy to adjust, which is convenient for precise fertilization. Liquid fertilizers are conveniently compounded with other agricultural chemicals (such as fertilizer synergists, insecticides, fungicides, herbicides, etc.) and moisture-absorbing organic materials (such as amino acids, fulvic acid, etc.) during the production process.
