1. The peat soil: The peat soil is used as edible fungus covering material, and the application effect in production is the best; but the domestic resources are less, and the distribution is uneven, mostly concentrated in the northeast and other regions, as a resource, its cost In addition to transport, the production cost has increased a lot. At present, the sales price of peat soil in Shandong Province (Jinan land price) is about 470 yuan per ton; in the case of Agaricus bisporus, the cost is increased by 7 yuan per m2. The output is increased by 30%, the output value is increased by 15 yuan, the input-output ratio is 1:2, and the experimental output is increased by more than 100%. The input-output ratio is more than 1:6, which is economically very cost-effective. The treatment of peat soil is very simple: use the “simple silly†mix and spray while mixing back and forth to use twice, then use it without cover film. 2. Ordinary soil preparation: In general arable land, the soil in the cultivating layer is considered to have high organic matter and suitable aggregate structure and is suitable for earth covering materials. However, we believe that due to the fertile soil in the cultivation layer, the soil microbial population is very high, which contains some microbial populations that are harmful to edible fungi, and should not be used in large quantities in actual production. The soil layer below 20 cm in the tillage layer has relatively low level of relative fertility and poor granule structure, but the amount of harmful microorganisms is small, and the effect can still be applied as a cover soil material after simple killing treatment. The specific operation is: a mushroom shed for every 100 square meters of cultivation area, Take about 5,000 kilograms of soil, smash and sieve while drying, so that the diameter of soil particles 0.5 to 1 cm and 0.3 cm or less account for 50% of the total, and then use the "overlay material treatment agent" with 800 times the octane sulfur Phosphorus is mixed and sprayed until it is confirmed that there is liquid adherence on each of the soil particles. The heap is covered and can be taken after one week. When used, the mound is spread out, and the internal exhaust gas is allowed to enter the shed. 3. Preparation of alumina: The material is rice husk and river silt, with a weight ratio of approximately 1:10; 4000 kg of river mud, 500 kg of rice husk and supplementary materials are prepared per 100 square meters of cultivation area; Treatment: Dried out by river mud While crushed, the rice husks were soaked in 4% lime water for about 20 hours, and then fermented with supplementary materials to make them fermented. Then the two were fully mixed, and the water content was adjusted to about 20% by water. Spray and mix well according to the method described above. Cover the film, turn it on every 2 to 4 days, turn it about 3 or 4 times, spread out the smell, and then use it.
