Method for producing organic water-soluble fertilizer by utilizing straws

Abstract

The invention discloses a method for producing an organic water-soluble fertilizer by utilizing straws. After compound bacteria are adopted for fermentation, compound enzymes are used for enzymolysis,the production technological process is optimized, the nitrogen, phosphorus and potassium nutrient content of the product reaches 300 g / L, organic matter content reaches 100 g / L, the fertilizer product is an alkaline fertilizer, and the product has the advantages of being fully water-soluble, high in activity, fully absorbed, quick in effect and high in water-soluble potassium content. The fertilizer is suitable for protected soil subjected to long-term fertilization and acidification, solves the problem of severe salt accumulation of greenhouse soil, can improve soil and increase the organicmatter content of soil, and effectively relieves the symptoms of soil acidification, hardening, fertility decline, nutrition imbalance and the like. After the product is applied, beneficial microbialflora can be activated, the activity of nitrate reductase is promoted, and amino acid and protein synthesis is accelerated; the water-soluble organic matters have strong permeability, promote protoplast flow of crops and plants, and accelerate nutrient absorption of root systems; and high-activity organic matters and medium trace element crops are directly absorbed without conversion so that thenutrition is comprehensively supplemented, and the effect is quick.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a method for producing organic water-soluble fertilizers from straws. Background technique [0002] Since the production of organic water-soluble fertilizers requires high technology, the country has not formulated relevant standards for organic water-soluble fertilizers. The relevant standards in the existing industry are generally the enterprise standards formulated by production enterprises. For a long time, there are few organic water-soluble fertilizer manufacturers in my country. , mainly because some coastal enterprises and foreign manufacturers with advantages in seaweed raw material resources produce water-soluble fertilizers, but the production volume is small, which is far from meeting the demand for use; Problems such as the seizure of raw materials and poor export links have also limited the development of domestic seaweed water-soluble fertilizer ente...

[0002] Since the production of organic water-soluble fertilizers requires high technology, the country has not formulated relevant standards for organic water-soluble fertilizers. The relevant standards in the existing industry are generally the enterprise standards formulated by production enterprises. For a long time, there are few organic water-soluble fertilizer manufacturers in my country. , mainly because some coastal enterprises and foreign manufacturers with advantages in seaweed raw material resources produce water-soluble fertilizers, but the production volume is small, which is far from meeting the demand for use; The seizure of raw materials and poor export links have also limited the development of domestic seaweed water-soluble fertilizer enterprises to a certain extent.

[0003] my country is a large agricultural country, and the production of crop by-product straw is also relatively large. However, the current application of straw is mainly to ferment or store it as livestock feed. The technology of using agricultural straw to produce organic water-soluble fertilizer is still immature. The existing The technology of using straw to prepare water-soluble fertilizer is mostly fermentation and enzymatic hydrolysis, but the simple fermentation and single-method enzymatic hydrolysis lead to low yield and poor benefit of water-soluble fertilizer production from straw, which makes it impossible to develop and implement on a large scale

The number of registered organic water-soluble fertilizer products in my country is relatively small, which is far from meeting the market and application needs.
