Some opinions and suggestions on Comprehensive use of waste from Edible Mushroom production

In the production of edible fungi, a large number of waste raw materials are produced every year, especially in the old producing areas and large-scale production areas. If these wastes are not disposed of properly and in time, it will bring great hidden trouble to the development of edible mushroom production. If it is light, it will cause environmental pollution, affect the output and quality of mushroom cultivation in the future, and seriously lead to the spread and harm of a large number of diseases and insect pests, resulting in serious production reduction and even no harvest. After planting mushrooms, many mushroom growers remove the waste from the mushroom house and field, and pile it around the mushroom farm for a long time to rot, while others are dumped in ponds, ditches, and lakes for a long time. These treatment methods are harmful but not beneficial. Here are some suggestions on how to deal with and utilize the waste of edible fungi:

1. Reuse and cultivate Coprinus comatus. The waste of straw mushroom, Pleurotus ostreatus, Lentinus edodes, fungus, mushroom and other varieties have been cultivated. As long as the mycelium grows well and the culture material is not contaminated by miscellaneous bacteria, it can be dried and crushed and added to the new raw material to cultivate Coprinus comatus, and the benefit is considerable. This method can not only reduce the production cost, but also further improve the utilization rate of raw materials.

2. Processed into bacterial bran feed. There are still a large number of hyphae in edible mushroom waste, while mycelial cattle contain a lot of protein and a variety of amino acids are not used. The raw materials with white mycelium growth and uncontaminated culture materials are dried and crushed in time, and about 10% are added to the feed to feed pigs, chickens and other livestock and poultry animals, which can also achieve the purpose of reducing breeding costs and improving efficiency.

3. Used as fertilizer for forest and fruit industry, crops and flowers. All kinds of raw materials after growing mushrooms are a kind of high-quality organic fertilizer. For example, if the circular grooves are carried out in orchards such as orchards, apples, pears and grapes, the grooves are 50 cm deep, and the waste of edible fungi is deeply applied and buried, which can improve orchard soil, improve fruit quality, and increase production and income. And the fertilizer effect is long-lasting and economical. It can also be used as cotton bud fertilizer, sweet potato and potato base fertilizer to significantly increase yield. In flower planting, the waste after mushroom planting is mixed with fertilizer soil and then accumulated and fermented naturally, which is used as the basic fertilizer for flower nursery and potted plants, which can improve the soil structure, ventilation, water retention and water holding capacity of flowers. The flowers grow luxuriantly, the flowers are gorgeous, and the cost is very low.

4. Used as sterilization fuel. For all kinds of mushrooms cultivated in bags, such as Pleurotus ostreatus, Lentinus edodes, Auricularia auricula, Flammulina velutipes, Populus edodes, Flammulina velutipes, Tremella fuciformis, Ganoderma lucidum, hericium Erinaceus, etc., the waste bacteria canister after mushroom production is dried and collected, and then used as sterilization fuel for the production of bacteria and clinker cultivation, which not only saves energy, but also saves production investment and prevents environmental pollution.

5. Used as heating fuel for mushroom shed. When the temperature is low in winter and spring, it is difficult to grow mushrooms in the plastic greenhouse without heating up. But most of the fuel used to heat up is coal. Heating with coal is not only a large investment and high cost, but also a waste of resources. Mushroom growers only need to change the structure of the heating stove slightly and change coal into edible mushroom waste, which can save a lot of fuel investment every year.
