Problems solved by technology

However, in this patent, the compost is piled outdoors. During the composting and fermentation process, the compost is prone to sourness, and the compost quality is unstable. In addition, no intelligent mushroom house is used in the planting, and the mushroom production is greatly affected by the environment, which in turn affects the quality of Agaricus Quality, the stability of product quality is not guaranteed

Embodiment 1

[0032] A method for cultivating low-cadmium Agaricus blazei using rice straw. The specific steps are as follows:

[0033] S1. According to the mass percentage, 30% of straw, 40% of corn cob and 24% of cow dung are mixed and pre-wetted to keep the water content at 68-72%. The pre-wetted mixed rice straw, corn cob and cow dung are mixed with 5% of soybean meal and urea 1% is mixed evenly to make compost, and the pile is built for 3 days, and the pile is 3 meters wide and 3 meters high, and the temperature is naturally raised to 50°C;

[0034] S2. After 3 days of building the pile, use a forklift, conveyor belt or throwing machine to evenly spread the compost in the intelligent ventilation fermentation tunnel. The intelligent ventilation fermentation tunnel is equipped with a frequency conversion fan and a timer, which can adjust the wind speed and air volume. According to the fermentation Control the temperature of the compost at different stages, accelerate the growth of microorg...

Embodiment 2

[0043] A method for utilizing rice straw to cultivate low-cadmium Agaricus blazei, the specific steps are as follows:

[0044] S1. According to the mass percentage, 33% of straw, 32% of corn cob and 30% of cow dung are mixed and pre-wetted to keep the water content at 68-72%. The pre-wetted mixed rice straw, corn cob and cow dung are mixed with 3% of soybean meal and urea 2% mixed evenly to make compost, build a pile for 2 days, make a pile with a width of 3 meters and a height of 2 meters, and naturally heat up to 55°C;

[0045] S2. After 2 days of building the pile, use a forklift, conveyor belt or throwing machine to evenly lay the compost in the intelligent ventilation fermentation tunnel. The intelligent ventilation fermentation tunnel is equipped with a frequency conversion fan and a timer, which can adjust the wind speed and air volume. According to the fermentation Control the temperature of the compost at different stages, accelerate the growth of microorganisms in th...

Embodiment 3

[0054] A method for utilizing rice straw to cultivate low-cadmium Agaricus blazei, the specific steps are as follows:

[0055] S1. According to the mass percentage, 40% of straw, 30% of corn cob and 25% of cow dung are mixed and pre-wetted to keep the water content at 68-72%. The pre-wet mixed rice straw, corn cob and cow dung are mixed with 4% of soybean meal and urea 1% is mixed evenly to make compost, and the pile is built for 3 days, and the pile is 4 meters wide and 2 meters high, and the temperature is naturally raised to 60°C;

[0056] S2. After 3 days of building the pile, use a forklift, conveyor belt or throwing machine to evenly spread the compost in the intelligent ventilation fermentation tunnel. The intelligent ventilation fermentation tunnel is equipped with a frequency conversion fan and a timer, which can adjust the wind speed and air volume. According to the fermentation Control the temperature of the compost at different stages, accelerate the growth of micr...

Abstract

The invention relates to a method for cultivating low-cadmium agaricus blazei murill by utilizing rice straws. The method comprises the following concrete steps: S1, pre-wetting the rice straws, corncobs and cow dung serving as main raw materials so as to prepare a culture material, carrying out piling, and carrying out natural heating; S2, filling an intelligent ventilation fermentation tunnel with the piled and heated culture material, regulating and controlling the fermentation temperatures of the culture material in different fermentation time periods by combination of a variable frequencyfan and a timer, and carrying out primary fermentation; S3, transferring the culture material undergone primary fermentation to a bed frame of a closed intelligent mushroom house, and carrying out secondary fermentation; S4, sowing agaricus blazei murill strains onto the culture material undergone secondary fermentation, covering the surface of the culture material with non-woven fabric to maintain moisture, and carrying out mycelium germination management; S5, laying a soil covering material prepared from red soil and turfy soil onto the surface of the culture material on which mycelia growso as to form a soil covering layer with a thickness of 4-4.5 cm, and carrying out mycelium culturing on the soil covering layer until the mycelia grow all over the soil covering layer; and S6, carrying out fruiting control and harvesting management.

Description

technical field [0001] The invention belongs to the field of edible (medicine) cultivation, and in particular relates to a method for cultivating low-cadmium Agaricus blazei by using rice straw. Background technique [0002] Agaricus blazei Murrill (Agaricus blazei Murrill) is native to the Piedade mountain grassland in Sao Paulo, southeastern Brazil, and is also distributed in southern California and Florida coastal grasslands, as well as in Peru and other countries. Agaricus blazei has the fragrance of bitter almonds, the content of protein and sugar is more than twice that of shiitake mushrooms, and it has high edible value because of its delicious pulp and delicate fibrous tissue. In 1975, Japan's indoor high-ridge cultivation method was successful for the first time. After hard work and improvement, the current large-scale artificial cultivation method was established. In 1992, the Institute of Soil and Fertilizer and Plant Protection Institute of Fujian Academy of Agri...
