Problems solved by technology

However, with the continuous increase of chemical fertilizer application, the shortcomings of its application are gradually exposed. The analysis is mainly manifested in the following aspects: low fertilizer utilization rate, serious soil compaction, deterioration of physical and chemical properties of soil, blocking soil pores, and destroying soil. Aggregate structure, causing imbalance of soil nutrients, compaction, pollution and decline in fertility

Embodiment 1

[0021] A soil conditioner containing threonine fermentation waste, prepared according to the following process:

[0022] 1) Collect bacterial protein and wastewater: filter the threonine fermentation waste produced by microbial fermentation of threonine to collect bacterial protein and wastewater;

[0023] 2) Hydrolysis and neutralization: Dry the bacterial protein, pulverize it into a powder, then put it in the reaction tank, add 5mol / L hydrochloric acid, subject to the raw material, stir and hydrolyze at 60°C for 24 hour, the stirring speed is 300 rev / min, neutralize the residual hydrochloric acid with ammonia water after the reaction is terminated, and the pH of the control solution is 7.0-7.2;

[0024] 3) Preparation of biological preparation A: crush peanut shells to obtain peanut shell powder, then mix and stir with wheat bran, rapeseed meal and fish bone powder to obtain a mixture, add twice the mass of the mixture in step 1) waste water, soak for 12 hour, then boiled ...

Embodiment 2

[0032] A soil conditioner containing threonine fermentation waste, prepared according to the following process:

Abstract

The invention discloses a soil conditioning agent containing threonine fermentation waste, which belongs to the field of soil conditioning agents. The soil conditioning agent is prepared through the following steps: 1) collection of mycoprotein and wastewater; 2) hydrolysis and neutralization; 3) preparation of a biological preparation A; 4) preparation of a biological preparation B; 5) preparation of a biological preparation C; and 6) preparation of the soil conditioning agent. The soil conditioning agent can realize yield increase of crops like paddy rice and sweet potatoes and improves soil quality.

Description

technical field [0001] The invention belongs to the field of soil conditioners, in particular to a soil conditioner containing threonine fermentation waste. Background technique [0002] Threonine is an essential amino acid, which is the second limiting amino acid in pig feed and the third limiting amino acid in poultry feed. With the wide application of lysine and methionine synthetic products in compound feed, threonine has gradually become an The main limiting factor for the growth of livestock and poultry. Threonine is mainly used as a feed additive. Its production steps are concentration, crystallization, and extraction of bacterial protein. However, the processing of bacterial protein and mother liquor produced in the process is difficult and costly, and it is difficult to obtain cost-effective by-products. [0003] In recent years, the production and application of various chemical fertilizers have been increasing, which has played an important role in promoting the ...
