Problems solved by technology

[0004] The development and application of fertilizers in my country is the main stage from farmyard manure to the use of inorganic fertilizers. Because farmyard manure has many pollution sources and a large amount of transportation, it is time-consuming and laborious to operate and the effect is not particularly obvious; while inorganic fertilizer has a single component and a relatively low utilization rate. Low, and often cause soil compaction and soil erosion to pollute water sources, affecting the ecological environment
At present, inorganic compound fertilizers containing nitrogen, phosphorus and potassium are mostly used in the market. The compound fertilizer has comprehensive fertilizer effects, but there are also defects such as short-lasting fertilizer effects and easy loss; more importantly, the current price of compound fertilizers is relatively high, which brings great harm to farmers. How to reduce fertilizer costs and increase farmers' income is a technical problem that modern agriculture needs to solve

Embodiment 1

[0025] A kind of biological bacterial fertilizer prepared by using glutamic acid fermentation waste, which is prepared according to the following method:

[0026] Step 1) Filtration of fermentation broth: the glutamic acid fermentation broth is sterilized by microfiltration membrane filtration, and the retentate and filtrate are collected respectively; The retentate and concentrated liquid are combined into feed liquid A for later use; among them, the microfiltration membrane is an inorganic ceramic membrane with a molecular weight cut-off of 2000MW and a microfiltration temperature of 40°C; the ultrafiltration membrane has a molecular weight cut-off of 300MW and an ultrafiltration temperature of 40°C;

[0027] Step 2) Decolorization, concentration and crystallization: The permeate obtained in step (1) is pumped into the decolorization tank for decolorization treatment, and 0.5% activated carbon of the permeate mass is added to the decolorization tank, and the temperature in th...

[0041] Fertilizer effect test of fertilizer of the present invention

[0042] 1. Fertilizer effect test for planting rice:

[0043] Set up two treatment test fields, the planting time is 2013, and the planting area is one mu, which are the control group and the experimental group. Control group: compound fertilizer (N23-P7-K6); experimental group: the biological bacterial fertilizer prepared in Example 1; the amount of fertilizer used in each test field was 50kg, the planting conditions were exactly the same, and rice was harvested at the same time, and the yield per mu of rice was measured and Yield increase rate; Simultaneously detect the number of rice spikes, thousand-grain weight and empty grains. The test results are shown in Table 1:

Abstract

The invention belongs to the field of fermentation waste liquid treatment in the biological fermentation industry, and discloses a biological bacterial fertilizer prepared by using glutamic acid fermentation waste, which is prepared according to the following method: step 1) fermentation liquid filtration, step 2) decolorization and concentration and crystallization, step 3) hydrolysis, step 4) preparation of liquid B and step 5) preparation of biological fertilizer. The biological bacterial fertilizer of the invention effectively utilizes amino acid fermentation waste, reduces fertilizer production cost, realizes turning waste into wealth, and the fertilizer is durable, which is superior to similar products in the market.

Description

technical field [0001] The invention belongs to the field of fermentation waste liquid treatment in the biological fermentation industry, and in particular relates to a biological bacterial fertilizer prepared by using glutamic acid fermentation waste. Background technique [0002] Glutamic acid is an acidic amino acid. The molecule contains two carboxyl groups, and its chemical name is α-aminoglutaric acid. Glutamic acid was discovered by Li Suxun in 1856. It is a colorless crystal with umami taste. It exists in a large amount in cereal protein, and the content in animal brain is also high. Glutamic acid plays an important role in the protein metabolism process in organisms, and participates in many important chemical reactions in animals, plants and microorganisms. Sodium glutamate, commonly known as monosodium glutamate, is an important umami agent that enhances the fragrance. Sodium glutamate is widely used as a food flavoring agent, either alone or in combination wit...
