Covered with soil and husk mushroom has good benefit.

In the routine cultivation and management of mushroom, soil mulching is a work with high technical requirements. Such as the quality of covered soil, soil aggregate structure, ventilation, water retention capacity and so on, all have special requirements. Especially in the production of large, medium and small covered soil particles, it is not only labor-consuming and time-consuming, but also labor-intensive. In order to effectively solve these problems, the author has repeatedly reformed the mushroom covering technology since 1990. Finally, it is determined to use the forest surface humus soil or paddy field tillage layer soil (sandy loam or clay loam) mixed with 5% fresh grain husk as mushroom covering material, and achieved good results. The specific methods are introduced as follows:

When the mushroom mycelium grows to 1 / 2 or 2 / 3 of the culture material, prepare enough soil on a sunny day and break it into pieces with a maximum diameter of no more than 2 cm. Then add 5% freshly processed fresh grain husk (note that there are no rice grains in the husk). After mixing evenly with the soil, spray repeatedly with 3% lime water to make the water content of the covered soil reach about 18%. Spray 500x carbendazim, 1000 times dichlorvos, 200x formaldehyde solution respectively, open the film after 24 hours of sealing, and cover the soil while the smell is wet. The thickness of the cover is 3cm, and the water content of the cover should be adjusted to about 20% within 1-2 days as required.

By using this soil covering method, not only the soil is convenient, labor-saving and time-saving, the soil aeration performance is good, it is not easy to solidify after spraying water, and the water-holding capacity is strong, and the output is 15%-20% higher than that of the conventional soil-covering method, and the product quality is also significantly improved.
