Pollution-free silicate bacterium fertilizer and preparation method thereof

Abstract

The invention discloses a pollution-free silicate bacterium fertilizer, which is composed of the following raw materials in parts by weight: 4 to 7 parts of tobacco powder, 3 to 5 parts of potassium sulfate, 40 to 60 parts of straw, 5 to 8 parts of potassium dihydrogen phosphate, 2 to 3 parts of trichoderma sp, 3 to 5 parts of copper sulfate, 4 to 6 parts of perlite, 5 to 6 parts of oyster shell, 6 to 8 parts of attapulgite, 1 to 2 parts of ammonium molybdate, 120 to 140 parts of chicken manure, 5 to 8 parts of wild buckwheat, 2 to 4 parts of silicate bacterium inoculant, 4 to 7 parts of wollastonite, and 5 to 7 parts of auxiliary agent. The fertilizer is mainly composed of chicken manure and straw, other additives such as ammonium dihydrogen phosphate, copper sulfate, and the like are added, thus the provided fertilizer can guarantee that crops have enough nutrients in each stage of growth, moreover, the agricultural wastes are fermented in multiple steps and converted into valuable resources, no pollution or residue is generated during the fermentation process, and thus the provided preparation method has a very good application prospect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a pollution-free silicate bacterial fertilizer and a preparation method thereof. Background technique [0002] It is a well-known fact that with the extensive use of chemical fertilizers, its utilization rate has been continuously reduced. This shows that it is limited to increase crop yields only by increasing the application of chemical fertilizers in large quantities, and the environmental pollution caused by the extensive use of chemical fertilizers is serious. The microbial fertilizer developed for this purpose can not only alleviate and reduce the pollution of agricultural products, but also improve the quality of agricultural products. Among them, the silicate bacteria can be used as bacterial fertilizer to dissolve insoluble potassium and phosphorus from minerals such as potassium-containing feldspar, mica, apatite, and rock phosphate powder in the soil for use by...

Problems solved by technology

However, as a living bacteria preparation, silicate bacterial fertilizer has a problem of validity period. When this kind of product is just produced, the content of live bacteria is high. With the storage time, improper transportation and changes in storage conditions, the number of effective microorganisms in the product will gradually increase. Reduce, reduce fertilizer performance, and there is no effective solution to such problems on the market
