Embodiment 1

[0034] A rice seedling raising cover seed soil, the volume ratio of its components is: 5 parts of decomposed Agaricus bisporus grass-soil mixture, 2 parts of edible fungus leftovers, 1 part of river pond mud, and 2 parts of rice chaff ash; Add 12kg of acidified soil, 60g of Dexon disinfectant and 0.3% soil conditioner by total weight to the seed soil.

[0035] The physical and chemical indicators of the finished seed cover soil are: water content ≤ 50%, organic matter ≥ 30%, total porosity 75%, bulk density 0.6g / ml, N+P 2 o 5 +K 2 O total nutrient content 2%, pH value 7, EC value ≤ 3 mS / cm, particle size ≤ 4.5mm, of which 2-4mm accounts for 60-65%;

[0036] The grass-soil mixture of Agaricus bisporus is a mushroom culture medium with rice and wheat straw as the main raw material, and the waste materials left after the growth of mushroom hyphae to produce mushrooms are piled and decomposed for more than one month, and then dried in the sun 1. The Agaricus bisporus grass-soil...

Embodiment 2

[0049] A kind of seedling soil for rice seedling raising, its raw material formula component volume parts are: 3 parts of decomposed Agaricus bisporus grass-soil mixture, 3 parts of edible fungus leftovers, 2 parts of frozen soil, 3 parts of rice chaff ash; Add 6kg of acidified soil, 60g of Dexon disinfectant and 0.1% soil conditioner by total weight to the seed-covered soil. The soil conditioner is Airmate—a pure natural soil conditioner produced by Shanghai Zifeng Agricultural Technology Co., Ltd., and the acidified soil is prepared by sulfuric acid and decomposed organic materials in a ratio of 1:3; the disinfectant is 100 times liquid enemy xon.

[0050] The physical and chemical indicators of the finished seed cover soil are: water content ≤ 50%, organic matter ≥ 30%, total porosity 60%, bulk density 0.35g / ml, N+P 2 o 5 +K 2 O total nutrient content is 1.5%, pH value is 5.5, EC value is 2.5 mS / cm, particle size is ≤4.5mm, of which 2-4mm accounts for 60-65%;

Abstract

The invention discloses rice seedling raising seed covering soil. A raw material formula of the seed covering soil comprises the following components in parts by volume: 3-5 parts of thoroughly decomposed agaricus bisporus and grass soil mixture, 2-3 parts of edible fungi leftovers, 1-2 parts of pond sludge, frozen soil or humus and 2-3 parts of rice chaff ash; besides, a proper amount of acidified soil and disinfectant and a soil conditioner with weight accounting for 0.1-0.3% of the total weight are added. The organic materials in the raw materials are thoroughly decomposed by adopting a high-temperature decomposition agent through composting fermentation and are mixed with other materials uniformly after being dried and ground, thus obtaining the seed covering soil. A preparation method of the rice seedling raising seed covering soil comprises the steps of raw material processing, raw material fermentation treatment, mixing and stirring, physicochemical index adjustment, acidified soil, disinfectant and soil conditioner addition, quantitative packaging and the like. The seed covering soil produced by taking mushroom leftovers as the main raw materials and fermenting the mushroom leftovers by adopting effective microorganisms has excellent effects, is very suitable for machine transplanted rice seedling raising, can promote rice seedlings to grow robustly and can be popularized and applied across the country.

Description

technical field [0001] The invention relates to an organic soil for rice seedling raising, in particular to a seedling soil for rice seedling raising and a preparation method thereof, belonging to the technical field of grain crop production. Background technique [0002] Rice is one of the food crops with the largest cultivated area in my country. Because seedlings must be raised before rice cultivation, for a long time, farmers need to prepare a large amount of nutrient soil as the seedling soil before seedlings every year, and the nutrient soil for seedlings must be fertile, neutral and slightly acidic, free of stubble, and free of gravel , no weeds, no pollution, no germs, loose soil, good permeability, and after autumn plowing, winter freezing, winter plowing, and spring plowing, then crushing, screening, acid adjustment, fertilization, prosperity control, and disinfection The surface soil of the cultivated paddy field after processing is used as seedling (seed) subsoi...
