Abstract

The invention relates to the technical field of the fertilizer, in particular to liquid fertilizer and a preparation method thereof. The liquid fertilizer is prepared from the following raw materials according to parts by weight: 42.3-67.8 parts of biogas slurry, 2.6-7.9 parts of sodium humate, 5.2-10.5 parts of potassium sulfate and 24.4-39.3 parts of urea. According to the liquid fertilizer disclosed by the invention, the soil character can be obviously improved, the function of a soil living body is strengthened, the soil environment quality is comprehensively improved, and soil-borne diseases can be effectively inhibited.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a liquid fertilizer and a preparation method thereof. Background technique [0002] With the development of agriculture, the range of production and application of liquid fertilizers is expanding day by day. Liquid fertilizer is a new type of high-efficiency compound fertilizer. Compared with solid fertilizer, liquid fertilizer has the advantages of good fertilizer effect, no agglomeration, various use methods, and less pollution during production, transportation and use, so it has been widely accepted. Consumers like it. [0003] There are many kinds of liquid fertilizers available, but their effects on improving soil properties and soil living functions are average, and they do not improve the quality of soil environment very well, and cannot effectively suppress soil-borne diseases. [0004] In view of the defects existing in the above-mentioned existing liquid fertilize...
