Straw Cultivation of Coprinus comatus

First, straw selection: use golden color, dry, no mildew, fresh straw. Aged straw should be rid of rot or mildew or contaminated parts, and turn over 2-3 days. It is best to use straw that can feed cattle.

Second, softening treatment: straw stem wrapped with a thick wax, epidermal cell silicate content is high, the silicon content of about 15% of the total amount of straw. If the softening treatment is poor, it is not conducive to the decomposition of the mycelia of the coprinus comatus using the cellulose and hemicellulose of the straw substrate. The old method of using lime water, rinsing with tap water, and stacking fermentation before it can be used for cultivation should be changed. The disadvantage is that tap water causes the loss of nitrogen and other nutrients in the straw matrix. We use the “free soaking and softening technology”. The selected straw is not chopped, chopped, soaked, or steamed. The straw is scattered on the drying floor. The rice straw is first rolled with a stone roll or beaten with a spade to crack the straw stem. Then use the crochet fork to remove the dust from the rice straw, and then splash it with 3% lime water until the moisture content of the rice straw reaches 65-70%. Use it directly for cultivation. The bioconversion rate (yield) is doubled compared to the old method. many.

Third, species selection: Coprinus species due to different biological characteristics, the yield difference. Not all Coprinus comatus varieties are suitable for cultivation of rice straw straws. The vast majority of Coprinus comatus varieties are only suitable for “two-stage” cultivation, that is, the first stage is inoculated with a plastic bag to inoculate bacteria (straw must be chopped or crushed) and the second section of mycelium full of bags is used to unpack the soil and produce mushrooms. The output is low. We chose the new species of Coprinus comatus “EC05” cultivated by our company. The temperature of the mushroom was 8-32°C. The annual cultivation was conducted regardless of the season. The bioconversion rate (yield) was stable at 150-250%, and the quality was superior.

Fourth, strain quality: The quality of good strains is the prerequisite for high yield and high efficiency. We should choose good Coprinus comatus cultivated species (3 species) with robust mycelium growth, pure color, no contaminating bacteria, and no color patches. It is best to use the "EC05" Coprinus comatus cultivar planted and bred by the general nutrient-rich, high-nitrogen, strain-based general-purpose medium for planting and cultivation. Because of this variety has a good "fixed nitrogen" ability. The high-nitrogen type strains can be directly neutralized with the higher carbon elements of the straw substrate, and the hyphae can grow robustly to ensure stable production and high yield.

Fifth, the method of covering soil: The thickness of the straw-stuffed cochineal bedding straw shall be set at 25 cm for the raw material rake type soil covering, about 20 kg of dried straw per square meter, and 3 kg for broadcasting the bacteria species. After sowing, it is pressed and pressed tightly with a wooden board or a shovel, and then covered with a 3 cm thick wet vegetable garden soil, manure soil or mixed livestock and poultry soil after exposure. This operation can make the loose straw structure compact, which is conducive to the growth of mycelium. While eating, the hyphae also absorbs the transmission of soil moisture and the supply of nutrients and trace elements in the soil. It also plays a good role in heat preservation, moisture retention, filtration of airborne bacteria, and suppression of pollution.

Six, timely harvest: Coprinus comatus fruiting body matures faster, should be in the bud stage of the fungus ring just loose, anti-crimping scales on the bell-shaped mushroom cap when harvested. If it is not harvested in time, the cap will break free from the stipe, or become black and rotten, and will flow out of the black-brown spore fluid to completely lose its product value, resulting in reduced production and income.
