Seedling raising matrix and production method thereof

Abstract

The invention relates to a seedling raising matrix and a production method thereof. The seedling raising matrix comprises the following components in percentage by volume: 15 to 45 percent of decomposed organic fertilizer, 20 to 50 percent of light material and 5 to 35 percent of binder, wherein the decomposed organic fertilizer is prepared by fermenting livestock and poultry excrement and auxiliary materials. The method comprises the following steps of: pretreatment, primary fermentation, secondary fermentation, decomposition fermentation, aftertreatment, fine treatment, and mixed treatment. After the measures are adopted, the produced seedling raising matrix is developed in packing and light, seedlings are robust, and the growth period is short; the problems that soil is difficult to take and vegetations are damaged when nutritional soil is used for raising the seedlings can be solved; the transmission of soil-borne disease is reduced; the production process for the seedling raising is simplified, and production efficiency is improved; after an organic fertilizer matrix is moved to a large field, a soil structure can be improved, and soil fertility is increased; the livestock and poultry excrement is used for producing the matrix, so that environmental pollution is reduced; and by the seedling raising matrix, integrated production cost is reduced, and the farming income of farmers is improved.

Description

technical field [0001] The invention relates to the technical field of soilless seedling raising and cultivation, in particular to a seedling raising substrate and a production method. Background technique [0002] With the rapid promotion of machine-transplanted seedling technology, conventional soil seedling raising is difficult to meet the relevant requirements, and due to the difficulty of soil extraction and destruction of vegetation for soil seedling raising, Chinese agricultural technicians have successively carried out research on new seedling raising technologies. The existing method is to use crushed rice husks instead of bed soil as seedling-raising substrates, firstly crush the rice husks, add enzyme bacteria, rice bran or wheat bran, urea, and water to the crushed rice husks and mix them evenly, and pile them into long strips Trapezoidal, covered with sacks, etc. for fermentation, when the rice husk turns brown or dark brown, the fermentation is completed. The ...

AI Technical Summary

Problems solved by technology

[0003] First, the source of the substrate is single, and the production cost is high

At present, rice husk or straw fermentation products are mainly used as the base material for seedling raising. The purchase cost of rice husk or straw is high, and the cost of raising seedlings is correspondingly increased, and the economic benefits of agricultural production are affected to a certain extent.

[0004] The second is that the fertility is insufficient, and special nutrients need to be added

[0005] 3. The production process is complicated, which is not conducive to industrial production
