How to grow oyster mushrooms in summer? A full analysis of key cultivation techniques

I. Site selection

For summer cultivation of oyster mushrooms, the site should be chosen in a shady place. Indoor floor space can be used, or, adapting to local conditions, they can be interplanted in crop fields outdoors that have a favorable ecological microclimate, such as fields of chili peppers, eggplants, corn, and rice, and between rows of melons and beans. If under well-shaded tree shade or under a grape trellis, small plastic bed sheds can be made, covered outside with straw curtains, creating a small environment convenient for manual temperature regulation.

II. Variety selection

Varieties should be chosen that have strong resistance to contamination and resistance to insects and diseases, of the broad-temperature type or high-temperature type. Such as Jiangdu No. 71, Early-Maturing 5-1, Jinfeng 2-1 and other varieties, all of which perform well in summer.

III. Cultivation management

Culture medium formula: cottonseed hulls 30%, miscellaneous sawdust 30%, corncobs 25%, wheat bran 10%, lime 2%, superphosphate 1%, gypsum 2%, with a water content of 62%-65%. Use low-pressure polyethylene tube film with a specification of 20 x 43-45 cm for filling the material, sterilize at 100°C for 10 hours, and inoculate after cooling. Place the plastic bags in a cool indoor spot for mycelial growth; after the mycelium has fully grown, transfer them to a suitable site for fruiting management. Open both ends of the mushroom bags, and stack no more than 3 layers. If interplanted in rice fields, they can be removed from the bags and arranged in a single layer between the rice rows. Spray water more than 3 times a day, following the principle of frequent light spraying. In the morning, spray water on the plant stems or vines; at noon, in addition to spraying water on the plant stems and vines, also spray water on the mushroom wall and the ground; at dusk, spray water only on the mushroom wall. When cultivating for fruiting indoors or in a shed, in addition to spraying water on the mushroom wall and the ground, also spray water on the walls and the air space. After each flush of mushrooms is harvested, promptly clean the bag openings, and spray a mixed solution of 0.2% dichlorvos plus 0.2% carbendazim to reduce pest and disease damage. If during the fruiting period pests are found and pesticide use is unavoidable, cypermethrin, which is low-toxicity and highly effective, should be used, with very good results.
