Embodiment 1

[0016] One, adopt liquid fermentation culture method to prepare the control root rot fungus seed liquid, culture medium is liquid and add yeast extract; In the preparation control root rot fungus seed liquid, target bacterial classification can be the root rot resistance bacterium in Bacillus subtilis, The specific fermentation conditions are: pH 6.2, culture temperature 24°C, and fermentation time 36 hours; in the preparation of the root rot fungus seed solution, the target bacteria can also be the root rot-resistant bacteria in the genus Paenibacillus polymyxa, and the fermentation conditions Specifically: pH 6.0-7.8, culture temperature 25-35°C, fermentation time 18-36 hours;

[0017] 2. Mix sheep manure with a moisture content of 70kg, bamboo vinegar stock solution of 10kg, and straw of 20kg in a compost tank, and use static forced ventilation for composting with a ventilation volume of 20m 3 / (h·t), after composting for 50-70 days to reach maturity, the pig manure compost...

Abstract

The invention discloses a preparation method of a microbial organic fertilizer capable of preventing and treating root rot of crops, and relates to a production method of an organic biofertilizer, and belongs to the technical field of fertilizers. The method comprises the following steps of: first, preparing a culture seed liquid which prevents and treats root rot by a liquid fermental cultivation method; performing compost treatment for fresh excrement with moisture content of 70-75%, 10-20% bamboo vinegar stoste and 10-20% stopping mixed in a compost groove; adequately mixing a matrix after fermental cultivation with a pig manure compost product by volume ratio of 1:3-5; and preparing the biological organic fertilizer which can prevent and treat culture of root rot. The fertilizer has the beneficial effects that the fertilizer can effectively prevent and treat root rot, and organic solid waste can be recycled by using household garbage as well as pig, cattle, sheep manures and the like.

Description

technical field [0001] The invention relates to a production method of an organic biological fertilizer, which belongs to the technical field of fertilizers, in particular to a preparation method of a microbial organic fertilizer capable of preventing and controlling crop root rot. Background technique [0002] Plant soil-borne diseases caused by pathogenic organisms such as bacteria, fungi and nematodes are an important class of plant diseases. With the help of soil protection, pathogenic organisms can survive in the soil for a long time, and once the host appears, they will infect in large numbers and cause serious losses. Root rot mainly harms seedlings, and can also occur in adult plants. In the early stage of the disease, only a few branch roots and fibrous roots are susceptible to the disease, and gradually expand to the main root. After the main root is infected, the early plants do not show symptoms. Later, as the degree of root rot intensifies, the function of abso...
