Problems solved by technology

In places where cattle breeding is relatively concentrated, cow dung is piled up randomly and the smell is so strong that it has a negative impact on the normal life of the surrounding residents; at the same time, cow dung is the source of the breeding and reproduction of various bacterial pathogens, which has a serious impact on the breeding population; In addition, when raw cow dung is directly used in the soil, it is easy to generate heat, consume soil oxygen, cause burning of roots and seedlings, and also spread the eggs of parasites and pathogenic microorganisms

Embodiment Construction

[0025] specific implementation plan

[0026] The raw materials of Examples 1-5 and their comparative examples are: fermented rice husk fermentation material, salt-washed coconut bran (EC value 0.37), washed cow dung (EC value 0.9), bagasse, vermiculite or perlite.

[0027] specific:

[0028]

[0029] (1) Take the rice husk fermentation material and mix it at a volume ratio of 1:1, adjust the carbon-nitrogen ratio to 25~30:1; add aerobic fermentation bacteria (the mass ratio of aerobic fermentation bacteria to rice husk fermentation material mixture is 1: 1000); after mixing, carry out strip-stack high-temperature fermentation, keep it for 4 to 5 days after the temperature reaches 65°C, turn it over for oxygenation and dehumidification; Invert the stack once every 5-7 days; until the fermented product is brown, fluffy and dry, the rice husk fermented product is obtained;

[0030] (2) Washing cow dung: Wash the cow dung in the cattle farm according to the ratio of cow dung ...

Abstract

The invention provides a special substrate for raising tobacco seedlings and a preparation method of the substrate, and belongs to the technical field of seedling cultivation in agricultural production. The tobacco seedling raising substrate which contains a rice husk-fermented material is prepared from coconut coir, bagasse, washed cow dung, the rice husk-fermented material, vermiculite or perlite at a certain ratio. The substrate has the advantages that the seedling raising environment is improved, the microbial environment of roots is improved, the problem of treatment of organic solid waste materials is solved, the production cost of the substrate is reduced, and the technical content of the product is also improved; and the substrate has a simple preparation process and convenient operation.

Description

technical field [0001] The invention relates to a substrate for cultivating tobacco crop seedlings and its production technology, belonging to the technical field of seedling raising in agricultural production. Background technique [0002] At present, most of the substrates for tobacco seedlings in my country are organic-inorganic composite substrates. The matrix is ​​made of peat as the main raw material, and some inorganic auxiliary materials are added. Peat is a short-term non-renewable resource, and continuous development will inevitably affect the ecological balance. It is imperative to find an ecological pollution-free tobacco seedling cultivation substrate. [0003] Rice husk is the outer shell of rice, mostly composed of thick-walled cells, rich in cellulose, lignin, and silicon dioxide. The carbon-to-nitrogen ratio of rice husk is as high as 75, which is one of the most difficult organic materials to ferment. [0004] Cow dung is the excrement of cows. In plac...
