Microbial organic fertilizer as well as preparation method and application thereof

Abstract

The invention discloses a microbial organic fertilizer as well as a preparation method and application thereof. The preparation method of the microbial organic fertilizer comprises the following steps of: mixing five types of bacteria liquid, including Klebsiella pneumoniae subspecies, Bacillus mucilaginosus, Bacillus megatherium, Bacillus subtilis and Thermophilic sporotrichum, with an organic matter base stock in a weight ratio of 1: 1: 1: 1: 1: 500 to obtain a mixture A and fermenting the mixture A, wherein the organic matter base stock is composed of poultry excrement, straws and humic acid-like substances in a weight ratio of 3: 3: 2; externally placing one bag of Streptomycesmicroflavus bacteria powder as B; and adding the bacteria powder of B into A according to the ratio of 0.2% to obtain the microbial organic fertilizer. The microbial organic fertilizer is applied to cotton and potato planting and grape planting under an extreme drought condition and the yield increasing effect is obvious. According to the invention, the technical difficulty of the fermentation of the existing microbial organic fertilizer is effectively solved, and nitrogen fixation, phosphorous decomposition and potassium decomposition effects are comprehensively achieved; and meanwhile, the microbial organic fertilizer is convenient for farmers, is simple and practical and has important application value.

Description

field of invention [0001] The invention relates to the technical field of biological fertilizers, in particular to the technical field of a microbial organic fertilizer and its preparation method and application. Background technique [0002] For a long time, in order to increase the yield in the planting industry, the existing technology has used a large amount of pesticides, chemical fertilizers and various growth hormones, resulting in the destruction of beneficial microbial populations in the soil, ecological imbalance, and rapid decline in soil fertility; soil is composed of inorganic substances It is composed of three basic units, organic matter and microorganisms, and the three are interdependent to form the soil ecosystem; inorganic matter is the main body of soil matter, which is not only the carrier of crop growth, but also the main source of inorganic nutrient elements for crops; organic matter is the soil supply The material basis of fertilizer and fertilizer pre...

Problems solved by technology

Streptomyces flavinus can also produce a variety of antibiotics to inhibit the growth of bacteria, which is very beneficial to the elimination of soil-borne pathogens; however, the number of Streptomyces flavinus growing naturally in the soil is too small to be insignificant; and there is no such strain in China at present artificial production, and there is no corresponding production process and production equipment

[0011] Compared with liquid fermentation, solid fermentation is more difficult to sterilize, the process is more difficult to control, and it is easy to contaminate bacteria or mold. The technology is very difficult, so it is difficult to succeed; therefore, solid fermentation is rarely used in China, and the relatively mature solid fermentation process is almost No; Streptomyces flavinus is bred from the soil, and its spore formation must be in a solid similar to the soil, and solid fermentation technology must be used; there is an urgent need in this field to provide an organic and inorganic fertilizer for Streptomyces flavinus, which can produce spores The solid fermentation process of Streptomyces flavinus and its production equipment are suitable for high-efficiency mass industrial production and are conducive to the green and environmental protection of my country's agriculture.
