Problems solved by technology

[0004] However, there are many problems in the liquefaction of microbial fertilizers, mainly because: 1. It is difficult to preserve microorganisms in liquid conditions, and the number of viable bacteria cannot be guaranteed; 2. Since the liquid contains a large amount of organic raw materials and nutrients, it is easy to spoil; 3. , The compounding of macroelements and microelements in liquid fertilizer directly affects the survival of microorganisms in it, and the product quality cannot be guaranteed
[0005] 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 present invention provides a liquid microbial fertilizer. The liquid microbial fertilizer comprises: 1-3% of micro-organism bacteria solution, 10-40% of yeast waste liquid, and a proper quantity of inorganic nutrients and water. In the micro-organism, the ratio of Bacillus subtilis fermentation to Streptomyces fermentation broth to jelly-like bacillus fermentation broth is 3: 0.5-3.0: 0.5-3.5. The present invention further provides a production method for the fertilizer. According to the liquid microbial fertilizer provided by the invention, the yeast waste liquid is taken as a major organic component for microbial fertilizer, thereby solving the problem of wastewater disposal in a yeast plant, and saving resources. The fertilizer provided by the invention, having both advantages of a liquid fertilizer and a microbial fertilizer, can not only exert an effect immediately, but also supply nutrient elements rapidly; moreover, the fertilizer can also improve soil organic matter, restore soil microbial flora, and extend application of the microbial fertilizer to the field of topdressing.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a production method of multifunctional liquid microbial fertilizers. 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 the...
