Problems solved by technology

However, these new fertilizers still have insufficient nutrients, high manufacturing costs, and no bactericidal and disease-resistant effects.
Due to the traditional heavy cropping in my country, a large number of pathogenic bacteria are accumulated in the soil, which seriously affects the grain production.
In recent years, the technology of straw returning to the field is being promoted. The straw cannot be decomposed in time, which seriously affects the growth and spread of the root system of crops at the seedling stage, resulting in a reduction in grain production.

Embodiment 1

[0036] The present embodiment contains the urea of ​​enzyme bacterium fermentation product, preparation steps are as follows:

[0037] (1) Preparation of enzyme seed solution

[0038] First, reactivate the enzyme bacteria strains stored in the glycerol tube at a constant temperature of 37°C for 24 hours, then spread the revived bacteria on the agar plate box with an inoculation loop, put them into the incubator and continue to cultivate at a constant temperature of 37°C After 24 hours, take 4 triangular flasks and put them into a sterilizing pot for 120°C sterilization for 15 minutes. After cooling, fill them with 200mL culture medium, close the mouth of the bottles, put them in a shaker after sterilization, and incubate anaerobically at a constant temperature of 37°C for 12 hours. To obtain the culture medium, select a 200L seed tank again, put steam into it to sterilize at 120°C for 20 minutes, put it into the culture medium after cooling, and then sterilize the real tank (s...

Embodiment 2

[0045] The raw materials and preparation method used in this example are the same as those in Example 1, except that the inoculum amounts in steps (1) and (2) are both 8% of the mass of the culture medium, and the biomass in the fermentation product of the enzyme bacteria is 25wt%.

[0046] The urea containing ferment bacteria fermentation product that embodiment 2 makes, composition comprises the urea of ​​mass content 99.2% and the ferment bacteria ferment product of mass content 0.7% (dry basis); The nitrogen content of urea is 46wt%, methylene di The urea content is 0.4wt% (calculated as HCHO); the biomass in the fermentation product of the enzyme bacteria is 25wt%, and the biomass is composed of the following components, based on the mass content of the fermentation product of the enzyme bacteria, 6.7% of effective live bacteria, 7.8% of Biomass, 10.3% organic matter and 0.2% trace elements.

[0047] The urea containing the fermentation product of the ferment bacteria pre...

Abstract

The invention discloses urea containing an enzyme microorganism fermentation product and a preparation method. The preparation method mainly comprises the following steps: preparing an enzyme microorganism fermentation seed liquid, preparing the enzyme microorganism fermentation product, performing high-tower spraying pelleting, and the like. The enzyme microorganism fermentation product is uniformly coated in urea granules, urea is applied into soil, under conditions of appropriate temperature, humidity, sufficient air and sufficient nutrition, beneficial microorganisms can grow and breed, a great deal of enzyme can be secreted to efficiently decompose crop straw and various organisms, and meanwhile formed dominant bacterial community can powerfully inhibit or kill pathogenic bacteria, so that the problems that crop growth can be affected by straw turnover and viruses can be accumulated because of continuous cropping planting can be substantially solved; and due to multiple enzymes, amino acids, organisms, trace elements and plant growth hormone in the enzyme microorganism fermentation product, root systems of crops can be well developed, the property of nutrition absorption can be improved, the utilization rate of fertilizers can be increased, and the purposes of stable and high yield can be achieved.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers and biotechnology, and relates to an antiviral urea, in particular to a urea containing fermented bacteria fermentation products and a preparation method thereof. technical background [0002] my country is a big agricultural country in the world. Due to the long-term excessive application of chemical fertilizers, the ecological environment has been seriously damaged. For this reason, new types of fertilizers such as coated controlled-release fertilizers, inhibitor slow-release fertilizers and melt urea-based compound fertilizers have been researched and developed at home and abroad, which can increase food production and reduce environmental pollution. played a positive role. However, these new fertilizers still have insufficient nutrients, high manufacturing costs, and no bactericidal and disease-resistant effects. Due to the traditional heavy cropping in my country, a large number of p...
