The most reasonable formula of Pleurotus ostreatus with corncob (fermentation material, high yield, high nutrition)

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

I. the formula of planting Pleurotus ostreatus with corncob

1. Formula 1: corncob 100kg, wheat bran 10-15kg, urea 0.3-0.5kg, potassium dihydrogen phosphate 0.1kg, quicklime 3-5kg, carbendazim 0.1%.

Formula 2: corncob 85%, wheat bran 10%, urea 0.4%, calcium superphosphate 1%, lime 4%, carbendazim 0.1%.

2. The method of planting Pleurotus ostreatus with corncob

1. Material selection

(1) the selected corncob should be relatively dry, yellow and white, fresh without mildew and deterioration, and can be crushed with ordinary feed grinder or sawdust slicing mill, and the sieve hole of the grinder needs to be expanded with a drill bit with a diameter of 2cm.

(2) if the crushed corncob is granular in the size of broad beans and soybeans, the general strains need to be selected according to the planting season. Low-temperature fungi are planted in late autumn, early winter, and medium-temperature fungi in early autumn, late winter and early spring.

2. Vaccination in bags

The main results are as follows: (1) first, take out the strain, then put it in a clean container, break it into a block the size of a jujube, send the bacteria with 50-55cm × 25cm polyethylene cylinder material, use a needle to tie 3 rows of microholes, first install 1 end, then put in the bacteria, fasten it with a rope, and then install one layer of bacteria and one layer of material, a total of 3 layers of materials and 4 layers of seeds, and the mouth of the bag needs to be tied up after filling.

(2) the amount of seed used is generally 10-15%, the temperature is 20-25 ℃, the relative humidity of the air is 50-65%, the light is darker, and attention should be paid to turning the bag and strengthening ventilation management at the same time. After about 15-20 days, the hyphae will grow into the mushroom management stage.

3. Mushroom production management

The main results are as follows: (1) Coral mushroom buds appear in the bacterial bag after about 7 days. at this time, the bag can be opened for mushroom production management, and it is necessary to grasp the time of bag opening. if the material surface is easy to dry too early, resulting in the death of mushroom buds, if it is too late, the quality of mushrooms will be affected. Generally, after opening the bag, it is necessary to increase light and strengthen ventilation and exhaust.

(2) when spraying water, do not spray water on the mushroom body. Wait for about 5-7 days before picking and listing Pleurotus ostreatus. Generally, growing Pleurotus ostreatus with corncob is not only economical and environmentally friendly, but also in line with the direction of green and sustainable development. but in the operation, to master the technology, in order to obtain better benefits.
