The tetracycline Mushroom summer species is more difficult than the common Agaricus bisporus. If the planting technique is extensive and the temperature during the fruiting period is too high or too low, it will cause failure. Now the high yield of the four species of mushroom Mushroom summer is described as follows: First, timely early planting early, early low temperature unfavorable mushroom mycelial growth; late planting, timely feeding of autumn mushrooms will shorten the mushroom mushroom period. Therefore, after the spring mushroom mushroom house is cleaned in late April, the summer mushroom culture material can be pre-wet and built. Second, the culture material fermentation 1. Culture formula (according to 110 square meters). 2000 kg of straw, 75 kg of gypsum, 25 kg of urea, 20 kg of compound fertilizer, 75 kg of superphosphate, and 50 kg of quick lime. 2. Culture material fermentation. Urea and superphosphate were added during the pre-wetting of the culture materials. After 6 days, the first tumbling was carried out. Gypsum and quicklime were added. Water was added to make up the moisture content of the culture material up to 65%. After 11 days, the second tumbling was performed. After the 14th day, the 3rd tumbling was performed, 0.1% carbendazim solution was added, the culture material was shaken, and the plastic film was stuffed for 1 night. The next day, the mushroom rack was fed and the temperature was sterilized. seal). When the temperature in the mushroom room rises to 60°C-62°C, it is kept for 7 hours to kill the pests in the culture medium. After that, the secondary fermentation of the culture material was carried out at a temperature of 50° C. to 52° C. for 120 hours. The secondary fermentation resulted in the loss of the original fecal odor and further ripening. A large number of white actinomycetes appeared on the material surface. And Humicola. Afterwards, the culture material was overturned, and the bad gas was eliminated, and water was added to make up to 60% of the water content. Third, sowing culture materials after the end of the fermentation, sowing the next day, with a seed amount of 100 bottles per 100 square meters species. The specific approach is: first leveling the mushroom bed, according to the amount of 2/3 of the species will be spread on the cultivation of cultivars on the material, and then mix the strains into a thickness of about 3 cm in the culture material, smooth the material surface, and then broadcast the remaining One-third of the strains are covered on the culture medium and gently tapped to tightly bind the strains to the culture medium. Finally, a layer of disinfected newspapers is overlaid on the medium to maintain the humidity and promote mycelial growth. Fourth, the bacteria when the wet newspaper on the bed is dry and the material surface is a little dry, you can spray water in the newspaper, with a degree of wetting. Spray water 1 or 2 times a day. Open the newspaper before spraying and allow the layer to ventilate. Then cover it and spray it. Do not spray too much water to prevent excess moisture from leaking into the material and affecting germs. After 20 to 25 days, the hyphae can be stretched from the bed to the bottom of the bed. 5. When the soil covered with mycelium is covered with soil, the soil pH of the soil is required to be between 7 and 7.5. The soil is firstly piled with 10% formaldehyde solution and 0.5% enemies, and then stacked tightly with a thin film. Closed for more than 24 hours, you can receive the effect of sterilization insecticide. The sterilized soil is covered in a mushroom bed with a thickness of 2 to 2.5 cm. 6. The water spray should keep the material layer and the cover soil in a wet state. In different growth stages, the water requirement is different, the growth stage of the mycelia, and the water requirement is slightly less; to the mushrooming period, the water requirement increases, especially the mushrooming. During the peak period, more water is needed. 7. Harvest When the fruit body grows to 3 to 4 cm in diameter, it can be harvested when it has not been opened. In the whole fruiting process of fruiting bodies, 3 to 4 times can be harvested.
