Recycling Technology of Golden Mushroom Cultivation Waste

First, the waste collection and Agaricus bisporus cultivation materials formula I in mid-April, Flammulina production is over, its cultivation waste bag drying, combined with the sun drying beat, broken to save concentrated rain. Bisporus sulphate cultivation material formula: calculate the dry weight of mushroom waste, add 3% superphosphate, 2.5% quicklime powder, 1.5% gypsum powder, 4% corn flour, 15% fresh cottonseed husk, then add 8% to 10% Euphorbia or rapeseed husk to improve the ventilation of the material.

Second, the reactor system for fermentation of Agaricus bisporus culture materials at the time of composting, according to the formula once the ingredients and mix well, the material's humidity is adjusted to 65% to 70%, composting fermentation for 15 to 20 days during the waiting heap temperature Natural rise to 60 ~ 70 °C, the first turn of the heap, turn over must pay attention to the material up and down, inside and outside the position to reverse, to ensure uniform fermentation, turning 2 to 3 times can be.

Third, the bagging sterilization After the completion of the composting fermentation, the diluted culture materials will exhaust the exhaust gas, and the water content of the adjustment material will be about 60%. The use of old bags longer than the needle mushroom bagging, the general bag size is 19 cm 33 cm low pressure polyethylene bags. When loading, press the fist with your hand, or use the machine to bag, reach the appropriate degree of tightness, and then conduct normal pressure steam sterilization for 8 to 10 hours.

Fourth, inoculation and germination management sterilization is complete, in the bag when the material temperature is less than 28 °C inoculation, each bottle of original species can be connected to 20 to 22 bags of culture materials. Inoculation boxes are generally used in summer and open vaccination can be performed in early spring and late autumn. Before the inoculation, the site was sprinkled with a mixture of lime powder and gemma net, in a ratio of 100:1, and 0.5% gemmyc was sprayed into the space or the air was purified. After inoculation, strains were cultured and cultured in sterile bags. In summer, the bacteria bags are discharged in a single layer and the roof of the greenhouse is covered with a shade net to cool the temperature; in early spring and late autumn, 3 to 4 layers can be stacked, and the double-membrane greenhouse plastic film + straw curtain + plastic film can be used for warming and heat preservation, timely ventilation, and protection from light. Under the promotion of hyphae germination is fast, after about 50 days, mycelium can be filled with bags.

V. Taking out bags and covering soil According to the climate and market price of fresh mushrooms, grasp the time of removing the bags and covering the soil. Tear the film of the bags and take them off. Place them flat on the ground or on the bed frame, cover the mixed soil of the large soil particles, and adjust the soil. The pH value of the pellets is 7.5. The soil particles are evenly sprayed with a 5% formaldehyde solution, and the membrane is sterilized for 24 hours to remove unpleasant odors. The treated pellets are transferred to the water content of the pellets. State, fill the gap when covering the soil, the thickness of the mixed material thickness of the material surface is suitable for 3 ~ 4 cm.

Sixth, diverting water from the mushroom When the mycelium extends to 2/3 of the covering layer, the general indoor temperature of the shed is controlled at 25°C in the late summer and early autumn; in the early winter, the temperature is above 10°C, and the mushroom water must be timely and accurately sprayed to promote mycelium growth. Kink, the amount of water spray is usually 2 to 3 times, to absorb enough water in the soil layer does not leak material prevail. When spraying mushroom water, ventilation must be increased more than usual. When the size of the bean sprouts appeared in the earth seam, mushroom water was sprayed in time to promote fruit body formation. During mushroom harvesting, indoor relative humidity is kept between 90% and 95%. The amount of water spray should be controlled flexibly according to the amount of mushrooms and weather conditions. Light spray, ground spray, and intermittent water spray are the main factors. Mushrooms are sprayed more and more. Multi-spray, less rainy days or not spray, avoid playing closed water, bogey in the indoor high temperature and before the mushroom spray, each wave mushroom appropriate increase in early ventilation, but need to maintain the mushroom shed relative humidity of about 90%, the latter mushroom Reduce the amount of ventilation properly, the entire cultivation and management process, and correctly handle the relationship between water spray, ventilation, and moisturizing, not only to increase the number of mushrooms, produce good mushrooms, but also to protect the hyphae, promote the vigorous growth of hyphae, vigorously in the middle period, and late Not premature aging.
