The following methods can be used to improve the production of straw mushrooms, double-sided mushroom bed frame first paved with 20 mesh plastic sieve, and then paved with inoculation, so that the bottom of the bed and the surface of the material at the same time mushrooms, which can shorten the production cycle and increase the yield by more than 20%. Cultivation with secondary inoculation of straw, 3~4 days after inoculation of heap grass, can be stuffed into the interstices of the grass layer for secondary inoculation, inoculation bed surface covered with soil. After the mycelium is full, the material surface is covered with 1~3 cm thick vegetable garden burnt soil or cooked soil, which can make the mushroom body fat and increase the yield by 20%~30%. Spraying rice water with 25% of rice bran water can increase the yield by 25%~30%. Spray rice bran water, take 40% rice bran, 30% peanut cake powder, 5% lime, 25% rotted urine, mix well, ferment in tank for 15-20 days, fish out, cook and filter. Take 4 parts of the filtrate, add 6 parts of water and spray it after picking the second straw mushroom.

Adjusting the pH after the first mushroom picking, supplementing nutrient solution, and adjusting the pH of the medium to alkaline can promote the recovery of the mycelium, prolong the mushroom picking period, and increase the amount of mushrooms. Spray 3% lime water into the material pile to adjust the pH to alkaline. Spray urea and bran water. Add 10 kilograms of bran to 100 kilograms of water, boil and filter it, take 50 kilograms of filtrate, add 50 kilograms of water, and the dosage of urea is 0.1%~0.2%. In the practice of mushroom cultivation, if there is no mulching, no substrate will be formed; whereas in straw mushroom cultivation, substrates can be grown with or without mulching. Mulching can make straw mushrooms fat, reduce dead mushrooms, improve heat preservation and adaptability to temperature change, and increase yield by 20-40%.

Covering soil on the surface of the material can reduce the evaporation and loss of water in the culture material and supply the water needed for the growth and development of the substrate. It can prevent "leakage" when spraying water. Therefore, mulching can indirectly increase the yield, especially in summer cultivation. Garden soil is the best mulching material, loose and breathable, strong water retention. The suitable pH value of soil is 7-7.5. Burnt soil has poor water retention properties and is not as effective as vegetable garden soil. General mycelium grow full cover soil, material surface cover soil thickness 1-3 cm.

Covering grass ash. When the surface of the material is covered with mycelium, a layer of 1 cm thick grass ash can inhibit the culture material from becoming acidic. Spraying 25% of rice water in the culture medium can significantly increase the yield of straw mushrooms and improve the mycelium's adaptability to low temperature, which can increase the yield by 25%~30%. Spraying 400 times of 30% ripened ganoderma solution after uncovering the film and the day after picking the mushrooms can lighten the color of the mushrooms. Mix 40% rice bran, 30% peanut cake powder, 5% lime and 25% decomposed urine, and then put them into a tank to ferment for 15-20 days. Boil the fermented and decomposed mixture, filter it, take 4 parts of the filtrate, add 6 parts of water and spray it after harvesting the second batch of mushrooms to increase the production of the third batch of straw mushrooms.
