Straw is a large amount of cheap resources, the current use value is not high. If we use the optimized techniques described in this article to cultivate Pleurotus ostreatus, we can increase its bioconversion rate and turn waste into treasure. The technology has the characteristics of simple process (no need for shredding and high-temperature cooking), low production cost (no need of investment equipment), short production cycle, high yield (bioconversion rate up to 200%). First, the choice of species. Such as grass Feng Yihao, Ping straw 126, rejuvenation 802 and so on. Cultivated species are best produced from nutritious food materials such as wheat, corn, grain, and cotton husks. Second, raw material preparation. The dry, mold-free straw material is put into a bubbler tank filled with water for 30 minutes, then removed and drained. During the process of stacking, 2 kg of warming starter (a kind of special fermentation agent for edible fungi) was uniformly thrown into every ton of material, and the stack height was 1 meter, width was 2 meters, and the length was not limited. Cover with straw or film. When the reactor temperature rises to 60°C, keep it for 2 days and turn it over. In the process of turning, 6-10 kilograms of urea are scattered evenly into each ton of material. When the temperature of the stack is raised again to 60°C, the pile is re-turned once and sprinkled with water to maintain the humidity. After 10-15 days of fermentation, the rice straw becomes tan and emits a clear scent. Cool the fermented straw pile. Third, the production of bacteria. Prepare the mold and the agricultural film first. Made of wood, 90 cm long, 60 cm wide, and 40 cm high, with no bottom and no cover molds, several more can be made when the production volume is large. The agricultural film is cut to a size of 200 cm and 170 cm, and one package is used. Put the mold into a clean culture room, place a piece of unfolded agricultural film in the mold, sprinkle a small amount of bacteria in the film, and then put it into a well-fermented culture material, squeeze it tightly, and spread the bacteria on top and around. Then use agricultural film to wrap the material, remove the film, and stack the bacteria in 3-5 layers. Fourth, bacteria culture. The prepared bacterial package is placed in a culture room to be shaded and cultivated, and ventilation and air cooling are performed. When the cover of the mycelium is covered, a part of the agricultural film can be pierced or torn on the bacterial package, and the package is checked and removed in time. Bacteria infected by bacteria, increase the amount of ventilation, until the bacteria bag full of hyphae. Fifth, base wall fruiting. When the bacterium bag grows well, the agricultural film is removed, and a ridge and a double row are used to form a bacterium wall. The lines are 30 centimeters apart and filled with soil. The earth-covering materials are mainly organic-rich paddy soil or vegetable garden soil. Add lime 1.5%, urea 0.5%, potassium dihydrogen phosphate solution 0.5%, add appropriate amount of water, mix and stack well, and use humidity to pick up the mixture. That is scattered degree. Between the layers filled with 3-5 cm thick soil, so that the line between the soil and fertilizer into a whole, generally stacked 5-7 layers as well. Then heat and moisturize, 10 days can buds mushroom. Cultivation sites can be indoor and outdoor, with outdoor shade as well. Six, fruiting management. After budding, keep the air relative humidity of mushroom house or mushroom shed more than 90%, and spray the water on the mushroom body when it is dry. After finishing a tidal mushroom, stop spraying for 2-3 days, and then the fungus and soil between rows of fungicides shall be fed with a nutrient solution of edible fungi or a mixture of 0.2% urea and 0.1% white sugar water. 10-15 days can be bud, a total of 4-5 tide mushroom.
Sterilization Container
The purpose of the sterilization box is to store the equipment in the process of packaging, sterilization, transfer, storage and so on. These orthopeadic instruments working mode is suitable for high pressure steam sterilization, not suitable for dry heat sterilization, ethylene oxide sterilization, ultraviolet sterilization, microwave sterilization and formaldehyde sterilization. The sterilization instrument box is divided into two parts,the cover and the body. The central area of the box cover is the filter system of the disinfection box, which is composed of quick filter system clasps and filter paper. The clasps need to be fixed by double keys, and the fixed sound can be heard during operation, which can effectively avoid the accidental loss of filter paper. Filter paper can be reused for 1 000 times, has chemical resistance, its chemical properties will not change with time, and its hardness exceeds steel. There is also a safety fit for the filtration system around the box cover, namely a silicone washer and a tension retaining ring. On both sides of the box there are handles, locks and sockets for indicating signs.
