Silicate bacterium fertilizer capable of increasing soil rapidly-available potassium content and preparation method thereof

Abstract

The invention discloses a silicate bacterium fertilizer capable of increasing the soil rapidly-available potassium content. The fertilizer is composed of the following raw materials in parts by weight: 90 to 110 parts of leftovers in pig slaughter house, 2 to 3 parts of borax, 22 to 26 parts of plant ash, 3 to 5 parts of potassium sulfate, 14 to 16 parts of wheat bran, 23 to 27 parts of coal ash and slag, 4 to 7 parts of monoammonium phosphate, 12 to 14 parts of river mud, 8 to 12 parts of biogas broth, 5 to 8 parts of ceramic particle, 6 to 9 parts of fermented glutinous rice, 5 to 7 parts of tree peony bark, 2 to 4 parts of silicate bacterium inoculant, 4 to 7 parts of wollastonite, and 5 to 7 parts of auxiliary agent. The formula of the fertilizer is reasonable and scientific, the fertilizer can protect the flowers and fruits and shorten the crop mature period, and at the same time the yield is increased. The added silicate bacteria can dissolve the phosphor and degrade the potassium and improve the soil granular structure at the same time; furthermore, the soil rapidly-available potassium content is increased, and thus the high yield of crops can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a silicate bacterial fertilizer for increasing the content of available potassium in soil 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 ...

AI Technical Summary

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
