Problems solved by technology

[0004] In the existing preparation process of microbial compound fertilizers, most of them use the process of adding bacterial agents during the granulation process. High temperature treatment will cause a large number of beneficial microorganisms to die, greatly reducing the effectiveness of the fertilizer after it is put into the soil; and after the fertilizer is applied, the effective time of the bacterial agent is short , poor repeatability and stability
In addition, there are also reports of mixing microbial agents into slow-release coating materials to prepare bio-coated fertilizers, but there are mainly difficulties in adding active bacteria, coating materials have an inhibitory effect on microorganisms, and the process is complicated and difficult to achieve the final product. Quality requirements and other issues
For example, when preparing controlled-release fertilizers (such as sulfur-coated urea) with inorganic substances as coating agents, it is necessary to heat the coating m

Abstract

The invention discloses a microbial coating agent for preparing a microbial compound fertilizer, which is prepared from 5-15% of curing agent, 35-75% of grease, 3-6% of surfactant and 10-55% of microbial culture, wherein the curing agent is a high-grade alkane mixture; the grease is animal fat, vegetable fat, petroleum extract or random-proportion mixture thereof; the surfactant is a conventional non-ionic surfactant or random-proportion mixture of the conventional non-ionic surfactants; and the microbial culture is a bacillus, azotobacter, actinomycete, microzyme or mycelial fungus culture, or a random-proportion mixture thereof. The coating agent disclosed by the invention is a non-aqueous microbial coating preparation, can realize high-concentration addition of active microbes into any granular fertilizer and implement coating, and has huge social meanings for development of environment-friendly fertilizers.

Description

technical field [0001] The invention relates to a non-aqueous microbial coating agent and a preparation method thereof, in particular to a microbial coating agent for preparing microbial compound fertilizers and a preparation method thereof, belonging to the technical field of microbial preparations and fertilizer production. Background technique [0002] In recent decades, the widespread application of chemical fertilizers has greatly improved the yield and efficiency of food production, making it an important means of production for increasing crop yield and harvest. During the application of ordinary chemical fertilizers, due to the processes of volatilization, leaching and infiltration, the loss of fertilizer efficiency and the huge waste of resources are caused. According to research, about 1 / 3 of the chemical nitrogen fertilizer applied to the soil enters the atmosphere, and the N 2 O destroys the ozone layer and produces a greenhouse effect; about 1 / 3 of the fertiliz...
