Soil-covering cultivation techniques of Pleurotus ostreatus

In the production of Pleurotus ostreatus, using the soil cultivation technology, 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 a technical innovation in the cultivation of Pleurotus ostreatus. 1. According to the theory, the water management in the cultivation of Pleurotus ostreatus is an essential factor for Pleurotus ostreatus to obtain high yield and high quality, including the water control of the culture medium, the moisture control of the surrounding humidity, the water control during the mushroom emergence period, and the water regulation during the growing period, and so on. On the other hand, soil-covering cultivation is easy to regulate and control water flexibly, which can better solve the problem of over-dry and wet. two。 The covering materials are relatively alkaline heavy loam with loose texture, many pores, good aggregate structure, wet and non-sticky, dry and 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 vegetable garden soil within 20 cm of the surface or topsoil in gullies and rivers. 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, spray 500x chlorothalonil and 1500 times dichlorvos after mixing well, and use after film sealing for 2 days. 3. The method of covering soil on the plane of border bed is generally adopted. After the full bag and post-ripening period of Pleurotus ostreatus, the cultivation site was opened according to 1.2 meters, the length of the bed was determined according to the site, the bed depth was 20 cm, the bottom of the border was dug and crushed, a small amount of lime powder was sprinkled, and dichlorvos and formaldehyde were sprayed to disinfect insects. Cut off the bacterial bag from the middle after taking off the bag. According to the inoculation face up in the border bed, the bag spacing is 5 cm. Sprinkle the prepared cover with space until the soil layer is 2 cm thick. Then flood irrigation is carried out to make the overlying soil layer absorb enough water and later make up the exposed or sunken area. 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, pay attention to keep the soil layer moist during the mushroom emergence period, transfer water to the fruiting body according to air temperature, ventilation and mushroom production, spray during water transfer, and it is best not to spray water before mushroom picking.
