Mushroom Cultivation in Pleurotus ostreatus Cultivation

Coprinus is an important limiting factor for the cultivation of oyster mushrooms in the early autumn and late spring. Effective prevention and control methods are the key to improving the success of Pleurotus ostreatus cultivation.

1. Choose high-quality culture materials, make full use of local materials for fermentation, use fresh, monotonous, mildew-free, no grease and sundries, physical properties, and suitable for cultivation of pleurotus ostreatus culture material, culture material before exposure 2 - 3 days. After the materials are piled, after the material temperature rises to 60°C, it must be maintained for more than 3 days. Every day, it is necessary to carry out the turning. When the pile is turned, the outer layer and the bottom layer of the bottom layer of the material should be turned to the center of the material pile to turn the inside of the pile. The culture materials were turned up and down and around the heap to facilitate uniform fermentation. Insufficient fermentation or excessive fermentation should be avoided.

2. When scientific ingredients are used, the amount of bran or corn flour added should be less than 15%, and the amount of urea added should be less than 1%. According to the production practice, the use of nitrophosphate fertilizer, binary compound fertilizer and phosphorus pentoxide content of 10-20% instead of urea can effectively avoid the occurrence of comatus, but the dosage should be controlled within 2%. The moisture content of culture materials is the key to the success or failure of cultivated oyster mushrooms. When using the corn cob fermentation material to cultivate Pleurotus ostreatus, the ratio of feed to water should be controlled to about 1:1.8, and when the cottonseed husk fermentation material is cultivated, it should be controlled at about 1:1.5. Raising the pH of the culture material is an effective way to suppress coprinus, and the amount of lime added is usually 3-5%.

3, the selection of high-quality strains to the regular manufacturers to buy the brand positive bacteria, the mother passed the generation of no more than 3 generations, cultivars from the original species transfer, do not transfer from the cultivar again for cultivation. The strains should be selected for age and adaptability; they should have strong anti-miscellaneous activity, high yield, and be suitable for the local cultivated species at that time. If you cultivate in early autumn and late spring, you should use medium and high temperature varieties; in late autumn and early spring, low and medium temperature varieties should be used. High-quality strains inoculate germinate quickly and grow faster; they can quickly fill the material surface and avoid the occurrence of comatus. Increasing the amount of inoculum is also an effective method.

4, make up the method when the bed planted, in the event of spooky umbrella seed entities, should be removed in time (before the open umbrella), so as not to spread after the formation of spores spores, and the spores in the spores of Health benefits lime powder, inhibit the ghost umbrella mycelium Grow. When the bag is planted, once the parachute occurs, it should be squeezed with fingers in the seed body for a few hours, so that it will not continue to grow after crushing. At the same time, the growth of Pleurotus ostreatus will be promoted after the growth of the mushroom mycelia. Grow. Pleurotus ostreatus can decompose the ghost mushroom seeds and does not affect the mushroom production. After the solution, it should be ventilated and cooled in time to increase the growth of mycelia of Pleurotus ostreatus and avoid the recurrence of ghost umbrellas.
