Problems solved by technology

Straw is an important agricultural and sideline product in northern my country, among which, returning straw to the field is the main method; the proportion of straw utilization as living fuel is also relatively high among various crop straw utilization methods; and straw production of biogas, straw power generation, and straw production of edible fungi The proportion of high-efficiency utilization of straw is still relatively low; there is still a considerable amount of straw that has not been used, and the waste of straw resources is serious.

Embodiment 1

[0027] A method for cultivating edible fungi using crop stalks, comprising the steps of:

[0028] 1) Crush crop stalks into fragments with a diameter of 0.5 cm, then mix the fragments with pine needles at a mass ratio of 10:1 to obtain a mixture; add water and cellulase to the mixture, and then Enzymolysis was carried out at 50°C and pH 5 for 8 hours to obtain an enzymolyzate; the amount of water used was 50% of the mass of the mixture, and the cellulase was added according to 50FGB / g of the mass of the mixture.

[0029] 2) Take 60 parts of the enzymatic hydrolyzate in step 1), 8 parts of corn flour, 4 parts of gypsum powder, 1 part of superphosphate and 15 parts of edible fungus fermentation liquid, mix and ferment for 6 hours, and then sterilize at 110°C Treat for 1 hour to obtain a medium for cultivating edible fungi.

[0030] 3) The culture medium is packed into the fungus bag according to 1kg / bag, and then the edible fungus strains are inserted into the fungus bag; the i...

Embodiment 2

[0033] 1) Crush crop stalks into fragments with a diameter of 1 cm, then mix the fragments with pine needles at a mass ratio of 10:1 to obtain a mixture; add water and cellulase to the mixture, and then heat the mixture at a temperature of Enzymolysis was carried out at 45°C and pH 5 for 9 hours to obtain an enzymolyzate; the amount of water used was 50% of the mass of the mixture, and the cellulase was added according to 50FGB / g of the mass of the mixture.

[0034] 2) Take 70 parts of enzymatic hydrolyzate, 7 parts of corn flour, 3 parts of gypsum powder, 1 part of superphosphate and 12 parts of edible fungus fermentation liquid in step 1), mix them and ferment for 5 hours, and then sterilize at 100°C Treat for 1 hour to obtain a medium for cultivating edible fungi.

[0035] 3) The culture medium is packed into the fungus bag according to 1kg / bag, and then the edible fungus strains are inserted into the fungus bag; the inoculated fungus bag is put into the cultivation room fo...

Embodiment 3

[0038] 1) Crush crop stalks into fragments with a diameter of 0.8 cm, then mix the fragments with pine needles at a mass ratio of 15:1 to obtain a mixture; add water and cellulase to the mixture, and then Enzymolysis was carried out at 40°C and pH 5 for 9 hours to obtain an enzymolyzate; the amount of water used was 50% of the mass of the mixture, and the cellulase was added according to 40FGB / g of the mass of the mixture.

[0039] 2) Take 70 parts of the enzymatic hydrolyzate, 8 parts of corn flour, 3 parts of gypsum powder, 1 part of superphosphate and 12 parts of edible fungus fermentation liquid in step 1), mix them and ferment for 7 hours, and then sterilize at 110°C Treat for 1 hour to obtain a medium for cultivating edible fungi.

[0040] 3) The culture medium is packed into the fungus bag according to 1kg / bag, and then the edible fungus strains are inserted into the fungus bag; the inoculated fungus bag is put into the cultivation room for fruiting cultivation; the fru...

Abstract

The invention discloses a method for culturing edible fungi by means of crop straw. The method comprises the following steps that the crop straw is crushed, the crushed straw and pine needles are mixed, and a mixture is obtained; water and cellulase are added in the mixture for enzymolysis, and zymolyte is obtained; the zymolyte, corn flour, gypsum powder, calcium superphosphate and an edible fungus fermentation broth are fermented; sterilization is conducted, and a culture medium for culturing the edible media is obtained; the culture medium is loaded in a fungus bag, and edible fungus strains are inoculated into the fungus bag; the fungus bag obtained after inoculation is put into a culture room for fruiting culture; in the middle of growth of the fungi, the fungi are picked, after fungus picking, dead fungi and rotten fungi are cleaned away, and fungus stalks are removed; then the fungus bag is covered with a thin film, and fruiting culture is conducted continuously. According to the method, the comprehensive utilization rate of the crop straw is effectively increased, and a new solution is provided for scientization and practical application of crop straw comprehensive utilization. The pine needles are adopted as the raw materials, a carbon source and nutrient substances are provided for growth of the edible fungi effectively.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation. More specifically, it relates to a method for cultivating edible fungi using crop stalks. Background technique [0002] my country is a big country in the production and export of edible fungi. According to incomplete statistics from the Ministry of Science and Technology, the annual total of edible fungi in China is about 9 million tons, with an output value of 40.8 billion yuan, accounting for more than 65% of the world's total. With the improvement of people's living standards in our country, the demand for edible fungi is increasing. Shiitake mushrooms, fungus, mushrooms, Flammulina velutipes, straw mushrooms, oyster mushrooms and other fungi are available in urban and rural areas across the country, and have become an indispensable non-staple food in people's daily life. Therefore, the development of edible fungi production has a broad market and a bright future. The raw material...
