First, arrange the production season reasonably. Pleurotus ostreatus is a kind of medium-low temperature mushroom. The growth stage of fruiting body is very short, the nutrient consumption is relatively small, and the whole cultivation cycle is long, about 240 days. In order to make full use of nutrients in the culture medium, in the seasonal arrangement, the original seed can be made in the middle and late June, the cultivated seed can be made in the middle and late July, and the cultivated bag can be made in August-September. 10 to April of the following year is the best fruiting period.

Second, the experimental selection of material formula. Broadleaf sawdust, cottonseed hull, corncob and wheat straw can be used as carbon sources, and bran, rice bran and corn flour can be added as nitrogen sources. The optimum ratio of carbon to nitrogen is 20: 1. According to this general requirement, the culture materials for cultivation can be adapted to local conditions, and various formulas can be selected by experiments.

Third, strengthen management of bag-making cultivation. In order to shorten the tidal period of Pleurotus ostreatus, it is best to choose the clinker bag cultivation method. Bagging and disinfection are the same as the cultivation method of Pleurotus ostreatus, and the disinfection time is not less than 10 hour. After taking out of the pot, the temperature of the feed is reduced to about 25℃ for aseptic inoculation. After inoculation, the mycelium can grow in the whole bag in 25-28 days at about 25℃ and air humidity of about 60%.

After the hyphae are full of bags, put them in the spawning room for about 7 days to reach physiological maturity, then move them into the mushroom room, and open the bag to produce mushrooms vertically. The general requirements of management are: in the early stage, we should widen the temperature difference, moderate astigmatism and promote a large number of differentiation of the original base; In the middle stage, the difference between temperature and humidity should be minimized to ensure the maturity of differentiation primordium. In the later stage, alternate temperature and humidity difference environment was created to promote fruit body hypertrophy. In case of pests and diseases, you can choose pollution-free Kemeiling and Mushroom Insect Net to kill them.

Fourth, timely harvesting and grading processing. When Agaricus blazei grows to maturity in June or July, the color turns gray or grayish brown, and the spores are not ejected before taking it. When harvesting, regardless of the size, it should be harvested at one time. After cleaning the material level, it should be sprayed with water again, and the water should be stopped for 2-3 days by covering the film, so as to turn the tide as soon as possible.
