Problems solved by technology

[0003] However, it is inconvenient to take a large amount of soil and seriously damage the topsoil layer. It is necessary to purchase part of the nutrient base. It is greatly affected by the weather and the seedlings are easily infected with soil-borne diseases.
[0004] In agricultural production, a large amount of agricultural waste materials such as straw straw and waste fungus materials have not been utilized, wasting resources and polluting the environment; part of rice straw is used for animal husbandry, but the digestibility is not high, the main reason is A large amount of fiber has not been converted; air pollution gases such as hydrogen sulfide, ammonia, carbon dioxide, and methane will be produced during the processing of rice straw agricultural waste
The waste fungus material is the polyethylene soft plastic fungus bag used in the production of fungi to fill the fungus culture material. After picking the mushrooms, the culture material filled with the polyethylene soft plastic fungus bag is used for burning or plastic recycling, burying, and discarding etc., causing environmental pollution

Embodiment 1

[0027] A nutrient matrix for raising seedlings comprises 50% of agricultural waste, 30% of soil, 10% of plant ash and 10% of fertilizer.

[0028] The agricultural reclaimed material is obtained by recycling the waste bacterial material after taking out the plastic sheet.

[0029] The agricultural waste and soil are in a pulverized state.

[0030] The fertilizer is a compound fertilizer produced by mixing phosphorus, phosphorus and potassium into granules.

[0031] The soil is black soil with an organic matter content of 10%.

Embodiment 2

[0033] A nutrient matrix for raising seedlings comprises 55% of agricultural waste, 28% of soil, 7% of plant ash and 10% of fertilizer.

[0034] The agricultural recycled material is obtained by recycling rice straw.

[0035] The agricultural waste and soil are in a pulverized state.

[0036] The fertilizer is a compound fertilizer produced by mixing phosphorus, phosphorus and potassium into granules.

[0037] The soil is yellow soil with an organic matter content of 20%.

Embodiment 3

[0039] A preparation method for seedling nutrient matrix, comprising

[0040] Screen agricultural waste to obtain agricultural recycling;

[0041] Obtain the soil below 20cm from the surface;

[0042] The agricultural reclaimed materials and soil are dried and crushed to obtain crushed coarse materials, and then the coarse materials are piled up with a height of 1.6m, and the piled materials are covered with a film for initial fermentation until there is a layer on the surface of the piled materials. Layers of white mold.

[0043] Add plant ash and fertilizer to the crude material after initial fermentation, stir evenly and spray clear water to obtain fermented material, the water content of said fermented material is 18%;

[0044] Secondary fermentation is carried out on the cover film of the fermentation material, the fermentation temperature is 50-60° C., and the pH range of the substrate is guaranteed to be 6-7 to obtain the nutrient substrate.

Abstract

The invention relates to the technical field of agriculture, in particular to a seedling culture nutrient medium and a preparation method thereof. According to the seedling culture nutrient medium and the preparation method thereof, agricultural recycled materials are used for replacing a large amount of soil, and energy consumption can be greatly reduced; the nutrient medium is prepared without being influenced by soil and seasons, the nutrient components of the medium are standard, and crops grow robustly; water and soil loss and fertility reduction can be effectively prevented, and nutritional ingredients of agricultural waste can be fully utilized; the influence of crop growth seasons is avoided; cost is low and preparation is simple; the improvement of existing soil organic matters and fertility is maintained; and through primary fermentation, fibers in the agricultural recycled materials can be decomposed to generate nutrient substances which are convenient to absorb by plants until a layer of white mould is formed on the surface of the compost, it can be proved that the generation of the nutrient substances and the start of corruption are immediately stopped, the fermentation temperature is 50-60 DEG C, the effect similar to pasteurization can be formed, and the nutrition matrix deterioration is avoided.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a seedling-raising nutrient substrate and a preparation method thereof. Background technique [0002] The nutrient matrix is ​​specially formulated to meet the growth and development of seedlings and contains a variety of mineral nutrients. It is a bed soil that is loose and ventilated, has a strong ability to retain water and fertilizer, and is free of diseases and insect pests. The nutrient matrix is ​​generally prepared by mixing fertile field soil and decomposed manure. [0003] However, it is inconvenient to take a large amount of soil, seriously damage the topsoil layer, and need to buy part of the nutrient base, which is greatly affected by the weather conditions, and the seedlings are easily infected with soil-borne diseases. [0004] In agricultural production, a large amount of agricultural waste materials such as rice straw and waste fungus materials have not be...
