Regenreatable plant waste and mud mixing type medium and its producing method

Abstract

The present invention discloses crop seedling growing medium produced with plant waste, domestic garbage and sludge from domestic sewage treatment as material and its production process. Crop stalk and other plant waste are crushed and used as the medium skeleton mixed with organic sludge and inorganic fertilizer, fermenting bacteria and other bacteria in certain ratio are inoculated, water is added, and the mixture is piled, aerated and fermented completely to produce the crop seedling growing medium. The present invention provides way of treating organic waste, and the crop seedling growing medium has excellent crop seedling growing effect and low cost.

Description

Technical field: [0001] The invention relates to a crop seedling-raising substrate, in particular to a crop seedling-raising substrate with renewable plant waste and sludge as main raw materials and a production method thereof. Background technique: [0002] Modern factory agriculture is gradually replacing the status of traditional agriculture. The basis of modern industrialized agricultural production characterized by mechanization and automation depends on industrialized seedling cultivation. Industrial seedlings need a substrate, but the substrate has strict requirements. Usually, the soil in the field is not suitable as a nutrient soil for industrial seedlings due to the pollution of fertilization and pesticides, and the instability of physical and chemical properties. Let alone the labor of moving the soil. The strength is also relatively large. Although the soilless cultivation supported by the nutrient solution can be used for industrialized seedling cultivation, t...

Problems solved by technology

At present, the commercially available seedling substrates include: (1) Natural minerals such as peat, vermiculite, perlite, and rock wool, and primary processed products are used as raw materials for making substrates. They are non-renewable resources and their distribution is limited. The high-quality peat used in the factory is mainly imported, which is expensive

(2) Using industrial and agricultural wastes, such as traditional Chinese medicine residues, papermaking industrial wastes, fungus chaff, etc., as raw materials for matrix manufacturing. The sources of these raw materials are also limited, and the processing is difficult, the process is not yet mature, and the quality is not stable. Difficult to promote and use

(3) Use full-nutrition chemical fertilizers as the matrix raw material, which contains all the nutrients needed in the crop period. It is easy to use, but the price is relatively high, and ordinary farmers cannot afford it.
