How to grow Pleurotus ostreatus? Precautions?

High-yield techniques of cultivating Pleurotus ostreatus with corncob

With the continuous expansion of the cultivation area of Pleurotus ostreatus, cottonseed hull, the main raw material for cultivation, is increasingly tense and the price is rising. Using corncob instead of cottonseed hull as the main raw material to cultivate Pleurotus ostreatus has low cost and high benefit.

(1) Treatment of corncob. Crushing corncob to peanut grain size, then mixing it with 3% ~ 5% lime water until it is completely mixed, and then adding 2% calcium superphosphate, 2% gypsum and 0. 5% urea, 0. 1% chlormequat (or other) and 1% salt, and mix them evenly to keep the water supply at 65438.

(2) Heap fermentation. After mixing evenly, pile up into a long pile with a width of 1.5 ~ 1.8m and a height of 0.8m, drill two rows of holes on the pile shoulder with wooden sticks, with an interval of 0.6 ~ 1m, cover with a film for thermal insulation, and leave a gap at the bottom of the pile for ventilation. When the temperature in the reactor 15cm reaches above 65℃, keep it for one day and night, then rotate the reactor, turn it up and down, turn it inside out, and repeat this for three times, and then spread it out for heat dissipation.

(3) Inoculating fungi. Select the appropriate high-quality third-class species. The size of mushroom bag is generally 22 cm× 45 ~ 50 cm, and the layered sowing method with three layers of materials and four layers of seeds is adopted, and the strain is about 15%.

(4) Mushroom management. The cultivation method of vertical wall or covering soil can be adopted. Nutrient solution: 5% ~ 1 0% soybean extract should be supplemented in time when harvesting1moist mushrooms. Generally, 3 ~ 4 tides can be harvested. The biological efficiency can reach 100% ~ 150%.

In recent years, with the development of off-season cultivation of edible fungi in China and driven by economic benefits, the production of Pleurotus ostreatus in summer has become one of the ways for mushroom farmers to increase benefits. However, due to the high temperature and serious pests and diseases in summer, it is still difficult for growers who lack cultivation experience. The following summarizes several key links of cultivating Pleurotus ostreatus in summer:

(1) seed selection. This is the premise of growing mushrooms in summer. This strain requires varieties to be resistant to high temperature, drought, humidity and impurities. Such as Gaoping 1, Wang Xia 40, Jiangdu 7 1, Xiayou 1, etc.

(2) batching, fermentation and bagging fermentation. The auxiliary material in the formula should be less organic nitrogen, not urea. It is advisable to add 5% ~ 8% lime, 0. 1 carbendazim or carboxamide, but pay attention to adding lime powder first. The water content is less than other seasons. The fermentation period is shortened appropriately. Performing high alkali treatment, and keeping the PH value of the culture medium above 8 before bagging. Plastic bags for cultivation have smaller specifications. Increase the amount of sowing and increase the number of sowing layers. After bagging, punch holes with nails where there are strains, and punch holes from the middle of the strain bag with a wooden stick with a thick little finger to speed up the growth of bacteria. Strengthen shading and temperature control when fungi occur, and ventilate at night to cool down. Strengthen oviposition management and improve oviposition quality and success rate.

(3) Cultivation and fruiting management. Because the heat generated in the fungus bag is not easy to be lost when the soil is covered, and there are many pathogenic bacteria and insect mouths in the soil, this method is generally not adopted, and vertical wall cultivation is usually carried out by stacking. When the mushroom comes out, roll up the fungus bags at both ends, ventilate regularly at night, increase air humidity and spray water, and do a good job of shading and controlling temperature and light. Do a good job in pest control in advance, and choose low-toxic pesticides that do not cause phytotoxicity after occurrence. Otherwise, high temperature environment is prone to phytotoxicity. Harvest in time. Keep the mushroom growing place clean.

Or you can cultivate it with sawdust! Pleurotus ostreatus is generally cultivated indoors, not underground. Disinfection must be thorough before inoculation! !
