Problems solved by technology

Because the coating oil used is animal oil or vegetable oil, mass production leads to higher cost
Application No. CN201210478807.7 "A Microbial Coating Agent for Preparing Microbial Composite Fertilizer", the coating agent is also prepared by using a curing agent, grease, surfactant and microbial culture ratio. Fat is animal fat, vegetable fat or petroleum extract, or a mixture thereof in any weight ratio. Similarly, the coating material used in this patent is also a fat substance, and the production cost is also relatively high. The additives occupy a high proportion of active ingredients after packaging, which affects the use efficiency and stability of the product
In addition, the use of grease will also cause inconvenience in packaging, transshipment and use of the product, and affect the appearance of the product

Abstract

The present invention provides a water-free oil-free microbial coating additive including alcosol, an organic protective agent and a suspending aid. The water-free oil-free microbial coating additive is particularly prepared from the following raw materials by weight: 10%-20% of the alcosol; 10%-20% of the organic protective agent; 1%-2% of the suspending aid and 58%-79%of an organic solvent. The coating additive is mixed with a microbial agent in the ratio of 1:3-1:1 for preparation of slurry, and the slurry is uniformly sprayed on the surface of the microbial agent powder by a coating machine for preparation of a microbial compound fertilizer. The coating additive has good film forming ability, and can improve the adhesion and the microbial coating efficiency of the microbial agent. At the same time because the coating additive is a water-free oil-free aid, in the microbial coating process, the coating additive can effectively maintain the activity of microorganisms, the proportion of the coating additive in useful components after the coating is low, the product use efficiency and use stability can be effectively improved, and farmland pollution can also be reduced. The present invention also provides application of the microbial compound fertilizer in crop growth.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a coating aid for microbial fertilizers, a microbial fertilizer prepared by using the coating aid and applications thereof. Background technique [0002] Fertilizer is an indispensable nutrient provider for human survival indirectly. Fertilizer comes from human beings and also acts on human beings. Plants can directly absorb and grow fertilizers. Chemical fertilizer is the largest material input in agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations, the absorption rate of plants to fertilizer is limited, and its absorption and loss coexist, and the effect on production increase accounts for 40-60%. On the one hand, the loss Fertilizers cause pollution of farmland and groundwater and waste of resources. On the other hand, crops cannot absorb fertilizers efficiently, resulting in a decline in yield and...
