Embodiment Construction

[0018] Below in conjunction with 6 examples the present invention is described in detail, but the present invention is not limited to the given embodiment.

[0019]

[0020] In the embodiment, the solid soil improver is first mixed with vermicompost, the EM stock solution is mixed with water, and then the solid and liquid components are fully mixed, fermented under airtight conditions for 6-7 days, and dried in the air. Measured by the standard method, the main indicators of the bio-organic fertilizer in Example 1 are: the number of effective viable bacteria (CFU) is 0.2 billion / g, the water content is less than or equal to 25%, and the organic matter is 62%; the main indicators of the bio-organic fertilizer in Example 2 are: The effective viable count (CFU) is 0.25 billion / g, the water content is less than or equal to 25%, and the organic matter is 60%. 25%, organic matter 64%; the main indicators of the bio-organic fertilizer in Example 4 are: the number of effective viab...

Abstract

The invention belongs to the technical field of a special biofertilizer for tobaccos, and relates to a no-pollution organic biofertilizer capable of inhibiting continuous cropping obstacle of flue-cured tobaccos. The organic biofertilizer is prepared by carrying out secondary biofermentation on the following raw materials in parts by weight: 5-8 parts of EM soil conditioner, 60-63 parts of wormcast (cattle), 0.5-1 part of EM stock solution and 34.5-28 parts of chlorine-free water. The invention has the advantages of high fertilizer efficiency, no adverse or side effect on soil and no pollution, can improve the structure and water retentivity of the soil, enhances the anti-disease capacity of flue-cured tobaccos, enhances the photosynthesis of flue-cured tobaccos, greatly improves the quality of tobaccos, and can obviously inhibit continuous cropping obstacle of flue-cured tobaccos. The invention has wide market prospects and good social and economic benefits in flue-cured tobacco production.

Description

technical field [0001] The invention belongs to the technical field of special biological fertilizer for tobacco, and uses biological technology to carry out secondary fermentation on solid materials such as vermicompost and soil improver with optimized ratio, so as to achieve the effects of improving soil, suppressing continuous cropping obstacles of flue-cured tobacco and improving the quality of tobacco leaves. Background technique [0002] When the same crop or related crops are continuously planted on the same soil, under normal cultivation and management measures, the phenomenon of reduced yield, poor quality, and poor growth status will also occur, which is called continuous cropping obstacle. Due to the limited amount of arable land and the increasing demand of the population for agricultural products, the phenomenon of continuous cropping in agricultural planting in my country and even around the world is common, and it still has a tendency to intensify. [0003] Af...
