Problems solved by technology

[0003] In the past, bacteria in liquid fertilizers were mostly added in the form of bacterial liquid, and there were certain differences between the nutritional conditions of the original medium and the conditions of the final product, which often caused the problem of bacterial colonization, and most of the microbial cultures used organic materials such as peptone. All are newly produced raw materials, with high cost and heavy resource consumption

Abstract

The invention discloses a microbial liquid. A fermentation medium used for preparing the microbial liquid comprises 40 to 60% of yeast waste liquid, 0.1 to 0.135% of starch, 0.35 to 0.45% of sucrose, 0.35 to 0.45% of peptone, 0.7 to 0.9% of soybean meal, 0.21 to 0.27% of KH2PO4, and water. The invention also provides a liquid microbial fertilizer prepared from the microbial liquid. The liquid microbial fertilizer comprises 1 to 3% of the microbial liquid, 10 to 40% of yeast waste liquid, an appropriate amount of inorganic nutrient, and water; wherein total nutrient N+P2O5+K2O provided by the inorganic nutrient is 4% or more. According to the liquid microbial fertilizer, yeast waste liquid is taken as the main organic compound, so that waste liquid disposal problem of yeast production enterprises is solved, and resource is saved. According to the liquid microbial fertilizer, advantages of liquid fertilizers and microbial fertilizers are combined, effect and supplement of nutrient elements are realized quickly, and application of microbial fertilizers is expended to the field of topdressing.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a liquid microbial fertilizer and a production method thereof. Background technique [0002] Liquid fertilizers are liquid products containing one or more nutrients needed by crops, and can usually be divided into clear liquid type, suspension type and paste type. Liquid fertilizer can precisely design the application formula and select the fertilization method according to the actual needs, so as to save the cost of fertilizer, improve the utilization rate of fertilizer, and is widely used in the cultivation of economic crops. Liquid microbial fertilizers add microbial factors to liquid fertilizers, which can not only provide nutrients for crops, but also supplement a variety of beneficial substances for crops, such as small molecule amino acids, humic acid, etc. There are usually 2-3 types of microorganisms contained in different liquid microbial fertilizers, and these mic...
