Embodiment 1

[0028] Preparation of powdery composite bacterial agent:

[0029] (1) Preparation of compound bacterial agent: Mix Saccharomyces cerevisiae agent, Bacillus subtilis agent and viridans agent with a mass ratio of 1:5:10 and an effective viable count of 100-300 million cfu / g, and mix them evenly. Obtain the compound bacterial agent.

[0030] (3) Preparation of rice flour: crushing the rice into flour with a fineness of not less than 80 meshes to obtain rice flour.

[0031] (4) Mix the composite bacterial agent with a mass ratio of 1:2 and rice flour evenly to obtain a powdery composite bacterial agent.

[0032] Preparation of Nutrients:

[0033] (1) Weigh wheat bran and rice bran according to the mass ratio of 1:4, mix them evenly to obtain the main ingredient, and set aside;

[0034] (2) Add 2 kg of brown sugar, 1 kg of urea and 0.5 kg of potassium dihydrogen phosphate for every 100 kg of main ingredients, and then mix evenly to obtain the mixture for later use;

[0035] (3)...

Embodiment 2

[0040] The preparation method of powdery composite bacterial agent and nutrient is the same as embodiment 1

[0041] Preparation of straw decomposing bacteria agent that can be stored for a long time under normal temperature conditions:

[0042] (1) Sterilize and dry seaweed powder and diatomaceous earth at high temperature respectively, then airtightly cool to room temperature, and set aside;

[0043] (2) First, mix 50kg of powdery compound bacterial agent with 100kg of seaweed powder, then add 750kg of nutritional agent, and finally add 100kg of diatomaceous earth, and mix it into a fluffy powder to obtain straw decomposing bacterial agent. After bagging Just leave it at room temperature.

Embodiment 3

[0045] The preparation method of powdery composite bacterial agent and nutrient is the same as embodiment 1

[0046] Preparation of straw decomposing bacteria agent that can be stored for a long time under normal temperature conditions:

[0047] (1) Sterilize and dry seaweed powder and diatomaceous earth at high temperature respectively, then airtightly cool to room temperature, and set aside;

[0048] (2) First, mix 60kg of powdery compound bacteria agent with 120kg of seaweed powder, then add 800kg of nutrient, and finally add 120kg of diatomaceous earth, and mix them into a fluffy powder to obtain straw decomposing bacteria agent. After bagging Just leave it at room temperature.

Abstract

The invention discloses a straw thoroughly-decomposing microbial inoculum capable of being preserved for a long time under a normal temperature condition. The straw thoroughly-decomposing microbial inoculum consists of the following components in parts by weight: 4-6 parts of a powdered composite microbial inoculum, 8-12 parts of a porous adsorbent, 70-80 parts of a nutritional agent and 8-12 parts of a water absorbent. Effective living bacteria preserved by the straw thoroughly-decomposing microbial inoculum are large in amount, strong in activity and fast in activation. The straw thoroughly-decomposing microbial inoculum can keep the flora activity for two years. Tests show that the amount of the effective living bacteria preserved by the straw thoroughly-decomposing microbial inoculum disclosed by the invention is more than or equal to 0.3 billion cfu / g(ml), which is far greater than the standard of the amount which is more than or equal to 0.5 cfu / g(ml) of an organic material thoroughly-decomposing agent product of the national ministry of agriculture (GB20287-2006); and the amount of the effective living bacteria can be kept to be more than or equal to 2 cfu / g(ml) after a half year of placement, more than or equal to 1 cfu / g(ml) after one year of placement, and more than or equal to 0.5 cfu / g(ml) after two years of placement.

Description

technical field [0001] The invention relates to a straw decomposing microbial agent, in particular to a straw decomposing microbial agent which can be stored for a long time under normal temperature conditions. Background technique [0002] Straw decomposing is the result of the synergistic effect of a variety of microbial flora, such as fungi, bacteria, yeasts and actinomycetes, among which various fiber-decomposing bacteria are the best. The number and activity of the dominant microbial flora are directly related to the maturity of straw. Therefore, how to preserve the effective number of viable microorganisms and the activity of microorganisms is the technical key to judging the quality of straw decomposing agent. General strains can only be preserved at sub-zero temperatures, and the preservation time at room temperature is short. Most of the microbial decomposed products need to be used at room temperature. How to increase the number of effective viable bacteria of mi...
