Silicate bacterial fertilizer prepared through two-stage fermentation and preparation method thereof

Abstract

The invention discloses a silicate bacterial fertilizer prepared through two-stage fermentation. The silicate bacterial fertilizer is prepared form the following raw materials in parts by weight: 8-10 parts of urea, 33-37 parts of wheat middling, 6-8 parts of illite, 3-5 parts of monopotassium phosphate, 2-3 parts of cupric sulfate pentahydrate, 22-26 parts of soya-bean cakes, 140-160 parts of excrements of livestocks, 3-4 parts of potassium sulfate, 4-6 parts of pepper meal, 23-24 parts of furfural residue, 5-8 parts of brown sugar, 5-7 parts of Chinese actinidia root, 2-4 parts of a silicate bacterial agent, 4-7 parts of wollastonite and 5-7 parts of auxiliaries. The fertilizer combines the advantages of inorganic fertilizer and organic bio-fertilizer, is prepared through a two-stage fermentation technique, is capable of providing quick-acting nutrients to crops, increasing the soil fertility, ensuring absorption of crops for nutrients for a long time and obvious yield increasing benefit, protecting the ecological environment of farmland, reducing the use of chemicals and improving the edible safety of crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a secondary fermented 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 b...

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
