Six-part production of Edible Fungi in Autumn

Qu 5: soil covering material, prepare in advance

1. Peat soil: as a covering material for edible fungi, the peat soil has the best application effect in production; but in China, this kind of resource is less and unevenly distributed, and it is mostly concentrated in Northeast China and other areas. As a resource, its cost plus transportation increases the production cost a lot. At present, the price of peat soil in Shandong (land price in Jinan) is about 470 yuan per ton. Take Pleurotus ostreatus as an example, according to the increase of 7 yuan in cost, 30% in yield and 15 yuan in output value per square meter, the input-output ratio is 1 ∶ 2. Some experimental yields are increased by more than 100%, then the input-output ratio is more than 1 ∶ 6, which is very economical. The treatment of peat soil is very simple: use "all kinds of diseases and silly" to mix and spray at the same time, mix it back and forth twice, and then use it when you don't need to cover the film.

two。 Preparation of common soil: on the general cultivated land, the tillage layer soil is considered to be high in organic matter and suitable for aggregate structure, so it is suitable to be used as soil covering material. However, we believe that because the soil in the tillage layer is fertile and the soil microbial base is very high, which contains some microbial populations harmful to edible fungi, it is not suitable to be widely used in practical production. The soil layer below 20 cm in the tillage layer has low level of relative fertility and poor aggregate structure, but the number of harmful microorganisms is small. After simple eliminate virus treatment, it can be used as a covering material. The specific operation is as follows: mushroom shed for every 100 square meters of cultivated area

After taking about 5000 kg of soil, it is dried while crushing and sieving, so that the diameter of soil particles less than 0.5 cm and 0.3 cm respectively account for 50% of the total, and then use "soil covering material treatment agent" with 800 times phoxim while mixing and spraying. until it is confirmed that there is a solution attached to each soil particle, build a pile and cover the film, which can be used in a week. When in use, spread out the mound, hang the internal waste gas a little, and then enter the shed to cover the soil.

3. Preparation of rice husk soil: the material is rice husk and river mud silt, and the weight ratio is about 1: 10; 4000 kg of river soil, 500kg of rice husk and auxiliary materials are prepared for every 100 square meters of cultivated area. Treatment: the river soil is dried and crushed, the rice husk is soaked in 4% lime water for about 20 hours, add auxiliary materials to stack fermentation to make it rotten, then fully mix the two, and add water to adjust the water content to about 20%, spray and mix well according to the aforementioned method, and then cover the film, turn the pile every 2 to 4 days, turn about 3 times, spread out and give off the smell and can be used.
