High-yield techniques of Pleurotus ostreatus cultivated with Rice Straw

High-yield techniques of Pleurotus ostreatus cultivated with Rice Straw

1. Select strains: experiments show that the ideal strains are: low temperature type 792118 Pleurotus ostreatus, medium temperature type Xinnong No. 1, 9400 Pleurotus ostreatus, Pleurotus ostreatus, high temperature type Hainan No. 2, etc. (this strain can be provided by Binhai County Edible Fungi Research Institute).

Second, the seasons are arranged: the areas along the middle and lower reaches of the Yangtze River can be sown from early August to mid-February of the following year, and the best sowing time is from mid-September to mid-November.

Third, straw selection: choose dry, mildew-free, golden straw, and glutinous straw, early straw and not next year straw is better.

(1) soak the straw in lime water and press the straw with stone, break the straw pipe, then tie it into a small bundle and put it into the soaking pool and press the weight on it. Soak in 3% lime water for 2 to 4 days, turning over the pool for 1 to 2 times to make it soak evenly. The soaking time depends on the temperature at that time. After soaking, the PH value of rice is between 8 and 9, and the water content is about 60%. After soaking the straw, it can be further stacked and fermented, so that the heap temperature can reach more than 60 degrees, and the heap can be turned once in the meantime.

Fourth, strain quality: the test shows that wheat grain bacteria and rice straw do not need to add organic auxiliary materials such as wheat bran and rice bran, which is of great benefit to prevent and reduce miscellaneous bacteria pollution. The bacterial age of cultivated species is 25-30 days for wheat seeds and 20-25 days for cottonseed hulls. Sowing rate: wheat seed 2025%, cottonseed shell seed 2530%.

Fifth, the production of bacterial materials: press materials and bacteria indoor bed frame cultivation, bed frame slightly tilted, in order to remove stagnant water in the material; after sowing, put boards on the film and press heavy objects. For outdoor cultivation, the bed should not be deep, and the depth of the bed with good drainage conditions is about 15 cm. If the drainage condition is poor, the bed can be made on the ground, and the inner circle of the border should be 15 cm high. After sowing, cover the film with a layer of straw, and then cover the grass with 5 centimeters of fine soil.

Sixth, replenish the nutrient solution: the stamina of rice straw is insufficient, and nutrition should be supplemented in the later stage to facilitate high yield. Specific methods: after harvesting a batch of mushrooms, you can spray mushroom Dazhuang, Zhuangzhuangsu, diammonium phosphate solution, or spray 0.2% urea plus 2% sucrose mixture, spray 3 kg per 100 kg of forage. Spraying nutrient solution can increase production by 15% to 20%.
