A New Formula of Pleurotus ostreatus with corncob

Formula 1: 100 kg corncob, 10-15 kg wheat bran, 0.3-0.5 kg urea, 0.1 kg potassium dihydrogen phosphate, 3-5 kg quicklime, 0.1% carbendazim. | | Formula 2: corncob 85%, wheat bran 10% urea 0.4%, calcium superphosphate 1%, lime 4%, carbendazim 0.1%.

The method of planting Pleurotus ostreatus with corncob:

1. Selection of materials

Corncob is required to be dry, yellow-white, fresh and mildew-free, and can be crushed by ordinary feed grinder or sawdust grinder. The sieve hole of the grinder needs to be expanded with a drill bit with a diameter of 2 cm, and it is appropriate for the crushed corncob to be granular in the size of broad beans and soybeans.

The strains were selected according to the cultivation season (low-temperature fungi were cultivated in late autumn and early winter, and medium-temperature fungi were planted in early autumn, late winter and early spring.

two。 Bagged inoculation

First, take out the strain, put it in a clean container, and break it into jujube-sized bacteria. 50-55 cm × 25 cm polyethylene cylinder material is used to send bacteria, three rows of microholes are pierced with needles, one end is installed first, the bacteria is put in, and the rope is used to tie it tightly. Then install a layer of bacteria and a layer of material, a total of three layers of material and four layers of species, and fasten the mouth of the bag after filling it, depending on the temperature of the bag, or pile it into a well-shaped stack, with a general seed amount of 10-15%. During the sterilization period, the temperature is 20-25 ℃, the maximum is not more than 35 ℃, the air relative humidity is 50-65%, and the light is required to be darker. Attention should be paid to turning the bag and strengthening the ventilation management during the sterilization period. After about 15-20 days, the hyphae can grow into the mushroom production management.

3. Mushroom production management

There are coral-shaped mushroom buds in the bacterial bag after about a week, and then the bag can be opened for mushroom management. To hold a good time to open the bag, the premature material is easy to dry, resulting in the death of the mushroom bud; too late will affect the quality of the mushroom. Increase the light after opening the bag. And strengthen ventilation and exhaust, pay attention to spray water can not be sprayed on the mushroom body. Pleurotus ostreatus can be picked and listed after about 5-7 days.

Growing Pleurotus ostreatus with corncob is economical and environmentally friendly, which is in line with the direction of green and sustainable development. But it is necessary to master the technology during the operation, so as to better ensure the benefit.
