High-potassium type liquid water-soluble fertilizer and production method thereof

Abstract

The invention provides a high-potassium type liquid water-soluble fertilizer. The high-potassium type liquid water-soluble fertilizer comprises nitrogen solution, water-soluble potassium polyphosphate, potassium chloride and potassium formate. The high-potassium type liquid water-soluble fertilizer comprises, by weight parts, 375-385 parts of nitrogen solution, 215-225 parts of water-soluble potassium polyphosphate, 95-105 parts of potassium chloride, 185-195 parts of potassium formate, 30-40 parts of chelating state microelement, 28-33 parts of surface active agent and 475-485 parts of water. The invention further provides a method for producing the high-potassium type liquid water-soluble fertilizer. The high-potassium type liquid water-soluble fertilizer has the advantages that the content of total nutrient of the prepared high-potassium type liquid water-soluble fertilizer is high, the high-potassium type N>=120 g/L, P2O5>=100 g/L, and K2O>=280 g/L; the high-potassium type liquid water-soluble fertilizer improves photosynthesis of muskmelons to promote the growth, and the vine length of the muskmelons is 73.0-75.4 cm; the relative amount of chlorophyll of the muskmelon leaves is 31.2-34.8%; and the morbidity of plant diseases and insect pests is reduced by 67-75%.

Description

technical field [0001] The invention relates to a high-potassium 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] After the fertilizer utilization rate is improved, it can not only save the cost of fertilizer, but also benefit the improvement of the ecological environment. First, it can reduce the energy and carbon sources required for fertilizer production, and reduce carbon dioxide emissions; second, it can reduce the amount of fertilizer in the soil. Residual amount, thereby reducing the pollution of water and soil by chemical fertilizers; thirdly, it can reduce the consumption of raw materials such as phosphorus and potassium fertilizers, and reduce environmental damage. [0004] At present, liquid fe...

AI Technical Summary

Problems solved by technology

[0007] (2) It has no or little effect on improving the disease resistance of crops;

[0008] (3) The degree of shortening the maturity period of crops is limited, generally within 1 day; the increase in sugar content and sugar content of fruits is not significant

[0009] (4) The ability to increase production is limited, generally below 10%;

[0010] (5) The existing solid water-soluble fertilizers have low utilization rates of nitrogen, phosphorus, and potassium, with nitrogen utilization rates of 30-35%, phosphorus utilization rates of 15-20%, and potassium utilization rates of 40%; fertilizer consumption is large and there is waste Adverse effects of fertilizers and polluting the environment
