biogas residue has comprehensive nutrient, loose texture, good performance of preserving soil moisture and moderating PH Value. It is a kind of good compost for artificial cultivation of mushroom. Compost that is used in mushroom can be used again as the fodder of pig or cow. Pig manure and cow dung can be utilized as the fermenting material of biogas.
Oyster mushroom is one of mushrooms which has largest cultivation area and high yield. Utilizing biogas residue to cultivate Oyster mushroom can get high success rate, stable yield and considerable economical benefits.
1. Season arrangement: the cultivation period and growing period of Oyster mushroom that belongs to high temperature type is in between April and August, August is the suitable season to cultivate Oyster mushroom which belongs to medium and low temperature, picking can be realized in next June.
2. Selection of material: there are many varieties of raw material that can be used to cultivate Oyster mushroom such as crops, corncob, peanut hull, sawdust, straw, dried mushroom residue, bagasse, vegetable leaves, all kinds of manure, biogas residue and fungi residues, people should choose materials which are fresh, dry, free from mould and sundries.
3. Scientific dosing: agriculture straw such as corncob 53%, sawdust 53%, straw 53%, biogas residues or fungi residues 30%, rice bran or wheat bran 10%, peanut bran 2%, gypsum powder 1%, lime powder 2%, compound fertilizer 2%, the proportion of material and water is 1 to 1.25.
4. Bagging: mix all mentioned materials well in polyethylene plastic bag that is 22cm*45cm*10cm and sterilize under atmospheric pressure for 10 hours.
5. The management of spawn sunning: after conducting inoculation, people could realize spawn running both indoors and outdoors. People should remain the highest temperature in under 28 degrees and check the temperature of fungus sack frequently. When finding that the temperature is higher than 28 degrees, people should immediately turn heaps and avoid the damage to spawns. In normal conditions, spawns will become fully grown in between 25 and 30 days.
6. Fruiting management: during the period of fruiting, people should give frequent ventilation, leave no dead angles and give certain scattered light.
