Embodiment 1

[0037] The screening process of embodiment 1 Straw mushroom cultivation substrate formula and preparation method thereof

[0038] (1) Screening of the dosage ratio of traditional Chinese medicine dregs and rice straw

[0039] According to the requirements of straw mushrooms on the physical and chemical properties of the cultivation substrate, five formulas of traditional Chinese medicine residue and straw were set according to different proportions. Among them, the traditional Chinese medicine residue was the residue after the active ingredients of Achyranthes bidentata, honeysuckle, dendrobium and scrophulariaceae were mixed and extracted, and cottonseed hulls and rice straw were used as the raw material. Contrast establishes six treatments altogether, carries out formula screening, and the ratio of Chinese medicine dregs and rice straw consumption (by dry matter weight percent) is as follows:

Embodiment 2

[0062] The preparation of embodiment 2 straw mushroom cultivation substrates

[0063] Achyranthes bidentata, honeysuckle, dendrobium, and scrophulariaceae mixed with fresh and wet traditional Chinese medicine dregs (water content 75-80%) were directly crushed once (convert fresh and wet traditional Chinese medicine dregs into dry matter weight, and the amount of dry matter used was 80 %), dry in the sun for one day in fine weather to reduce the water content to (65-70%), and add a warming starter 1kg / m 3 Mix well and build a heap to cover and ferment; after 24-48 hours, the heap temperature reaches 65-75°C, keep it for 10-15 hours, turn over the heap for the first time, and add 20% in proportion, and soak it in 4-5% lime water before crushing for 4 After 5 hours, drain the straw, cover it and continue to ferment, turn it over for the second time every two days, and add 10kg / m at the same time 3 Yield-increasing agent, mix evenly, and put it on the shelf for cultivation after ...

Embodiment 3

[0065] The preparation of embodiment 3 straw mushroom cultivation substrates

[0066] Achyranthes bidentata, honeysuckle, dendrobium, and scrophulariaceae mixed with fresh and wet traditional Chinese medicine dregs (water content 75-80%) were directly crushed once (convert fresh and wet traditional Chinese medicine dregs into dry matter weight, and the amount of dry matter used was 80 %), dry in the sun for one day in fine weather to reduce the water content to (65-70%), and add a warming starter 3kg / m 3 Mix well and build a heap to cover and ferment; after 24-48 hours, the heap temperature reaches 65-75°C, keep it for 10-15 hours, turn over the heap for the first time, and add 10% according to the proportion, and soak it in 4-5% lime water before crushing for 4 ~ After 5 hours, drain the straw, cover it and continue to ferment, turn it for the second time every two days, add 5kg / m at the same time 3 Yield-increasing agent, mix evenly, and put it on the shelf for cultivation ...

Abstract

The invention discloses a straw mushroom culture medium and a method for circularly cultivating straw mushrooms. The straw mushroom culture medium comprises 70 to 90 weight percent of Chinese medicament dreg, 10 to 30 weight percent of straws and a production increasing agent with the dose of 5 to 10 kg / m<3>, wherein the production increasing agent is prepared by mixing the following components in percentage by weight: 0.006 to 0.01 percent of vitamin B1, 15 to 20 percent of superphosphate, 40 to 60 percent of quick lime, 1.5 to 2 percent of magnesium sulfate, 0.2 to 0.4 percent of zinc sulfate, 0.2 to 0.3 percent of boric fertilizer, 0.2 to 0.4 percent of triacontanol and 22 to 37 percent of starch. By the straw mushroom culture medium and the method for circularly cultivating the straw mushrooms, resources can recycled; energy is saved due to short fermentation time of the medium; the medium can increase yield of the straw mushroom, can improve the quality of the straw mushroom and can increase the flavonoid content of the straw mushrooms; and by the multi-time circularly cultivating method, the utilization ratio of the medium is increased and production cost is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural edible fungus cultivation, and relates to a straw mushroom cultivation substrate and a method for circularly cultivating straw mushrooms. Background technique [0002] In recent years, my country's edible fungi industry has developed rapidly and has become a major producer of edible fungi in the world. According to statistics, in 2002, the total output reached 8.675 million tons, accounting for 65% of the world's total, of which about 200,000 tons of fresh straw mushrooms accounted for More than 60% of the total production of straw mushrooms in the world. At present, cottonseed husks and waste cotton are mainly used as the main raw materials in production, and rice straw, wheat straw, corncobs, wheat bran, etc. are used as auxiliary raw materials. On the one hand, due to the large amount of pesticides used in the cotton planting process, the cottonseed husks and waste cotton have high pesticide residue...
