How to improve the benefit without increasing the cost the soil-covering cultivation technique of Pleurotus ostreatus

In the production of Pleurotus ostreatus, the soil-covered cultivation technology is adopted, the mushroom body is enlarged, the handle is short, the cover is thick, the color is bright, the taste and flavor are good, and the yield can be increased by 30% to 50%. It is an innovation of Pleurotus ostreatus cultivation technology without increasing cost.

Soil-covered cultivation of Pleurotus ostreatus

1. Theoretical basis:

The water management of Pleurotus ostreatus cultivation is one of the factors to obtain high yield, including regulating the moisture in the culture medium, the surrounding humidity and moisture, the moisture in the mushroom stage, and the moisture in the growing period. On the other hand, soil mulching cultivation is easy to regulate and control water flexibly, which can better solve the problem of too dry and wet Pleurotus ostreatus.

two。 Selection of soil covering materials:

It is better to use alkaline heavy loam with loose texture, many pores, good aggregate structure, wet and non-sticky, dry, strong water storage capacity and high content of organic matter. Avoid too many clods, sand and raw soil. The improved soil can also be prepared by taking the vegetable garden soil or gully river topsoil in the surface 20cm, and after crushing, remove crop residual roots, debris, add 10% plant ash, 10% cottonseed shell, 2% calcium superphosphate, 0.2% urea, 3% lime powder, 1% salt, mix well, spray 500 times chlorothalonil and 1500 times dichlorvos, and use the film after 2 days.

3. Soil covering method:

The method of covering soil on the plane of the bed is generally used. After full bag and post-ripening period, Pleurotus ostreatus was opened according to 1.2m in the cultivation site, the length of the bed was determined according to the site, the bed was deep 20cm, the bottom of the border was dug and crushed, a small amount of lime powder was sprinkled, dichlorvos and formaldehyde were sprayed, and the insecticides were disinfected. After the bacteria bag is removed, cut off from the middle. According to the inoculation face up, vertically arranged in the border bed, bag spacing 5cm. Sprinkle the soil over the gap until the soil layer is thick 2cm. Then flood irrigation is carried out to make the overlying soil layer absorb enough water and later make up the exposed or sunken parts. Finally, the bacteria were cultured with plastic film. Other management with the same rules. In this way, the bud can appear in about 7 days, the soil layer should be kept moist during the mushroom emergence period, and the water should be transferred to the Pleurotus ostreatus fruiting body according to the air temperature, ventilation and mushroom yield. when the water is transferred, the spray should be carried out, and it is best not to spray water before mushroom picking.
