A New Formula for Fast growth and High yield of Pleurotus ostreatus

Tea mushroom, also known as tea tree mushroom, is a rare delicious health food, which sells well in the market. at present, the price of fresh mushroom is up to 20 yuan / kg. At present, the yield of artificial cultivation of Pleurotus ostreatus is low, which is mainly controlled by the strain and the formula of cultivation materials. In this paper, several ideal new formulas of cultivation materials are introduced as follows:

1. Tea shell powder 70%, rice bran 20%, tea meal powder 5%, sucrose 2%, lime 1%, gypsum 1%, potassium dihydrogen phosphate 1%. Take the dry material according to the formula ratio, the ratio of material to water is 1 ∶ 1.25, mix well, pile up and pat tightly for one night, pack it into dry material bags, uniformly compacted, sterilize at 121℃ for 2 hours, and inoculate at both ends after cooling. After inoculation, the cultivation material was placed under the condition of temperature 22: 26 ℃ and air relative humidity 60%-70%. During the period of mushroom production, the air relative humidity is increased to 90%, which is managed according to the routine. Its yield is higher than that of cottonseed shell culture material, increasing by 47.4%. The tea mushroom cultivated by tea shell and tea cake has a more delicious taste and stronger flavor, and this formula is suitable for promotion in tea-producing areas of Shandong Province.

2. Dried rice straw meal 15%, wheat bran 15%, cottonseed husk 59%, corn meal 7.4%, lime 3%, potassium dihydrogen phosphate 0.3%, magnesium sulfate 0.3%. The raw materials are weighed according to the proportion of the formula, mixed evenly, and mixed while adding water, so that the water content of the culture material can reach 60% to 65%. Then put the culture material into a polypropylene plastic bag with a specification of 15cm × 30cm, put on the ring and plug it with cotton plug. Sterilized under atmospheric pressure for 12 hours and 14 hours at 100 ℃, then inoculated after cooling.

3. Sawdust 36%, cottonseed shell 36%, wheat bran 20%, corn meal 5%, tea cake 1%, lime 1%, sugar 1%. The culture material should be fresh and mildew-free. When crushing sawdust, add 20% to 30% bark to increase the nitrogen content of sawdust. The size of sawdust particles should be moderate, and the sifted particles should be less than 0.4 mm. The suitable ratio of material to water is 1 ∶ 1.2 to 1.25. A polypropylene plastic bag of 17cm × 33cm × 0.0085 cm was used and packed into two layers. The packing should be completed within 4 hours and inoculated below 100cm ℃. The bacteria bag was put into the culture room for culture. This formula is used to cultivate Pleurotus ostreatus, generally, the mushroom can be collected in 3-5 tide, the fresh mushroom is 0.2-0.25 kg per bag, and the bioconversion rate is 70%-80%.
