NOVELTY - Cultivating Pleurotus eryngii, comprises (i) pre-wetting the cultivation material; (ii) adding the mixed cultivation material into a packaging bag; (iii) carrying out high pressure sterilization; (iv) inoculating strain into cultivating bag, and culturing, removing the cover from the cultivation bag, and then opening-bundled plastic sleeve ring, and cultivating for 17-19 days, and carrying out Pleurotus eryngii growing management for 9-10 days under diffusion light of 500-1000 1x in the cultivation room; and (vii) recovering Pleurotus eryngii.    USE - The method is useful for cultivating Pleurotus eryngii (claimed).    ADVANTAGE - The method has simple process; increases labor productivity; has high quality product, and biological conversion rate; and is environmental friendly, and economical.    DETAILED DESCRIPTION - Cultivating Pleurotus eryngii, comprises (i) choosing mixed cultivation material, pre-wetting by adding water under stirring conditions, where the water content in the pre-wet material is 64-66%, and the pH is 6-7; (ii) adding the mixed cultivation material into a packaging bag to obtain a cultivation bag, punching holes on the cultivation bag by inserting a plastic rod, and opening the bundled plastic set with a ring, and plugging up a set of closely cultivation bag cover; (iii) carrying out high pressure sterilization of the cultivating bag under vacuum conditions, and cooling by transferring the sterilized cultivation bag into a first pre-sterilized cooling room to naturally cool at not greater than 40 degrees C, and transferring the sterilized cultivation bag into a second pre-sterilized cooling room to naturally cool at not greater than 25 degrees C; (iv) inoculating strain into cultivating bag by using an air purification pipeline liquid under cooling conditions, and inserting pulling rod into the plastic cultivation bag, transferring the cultivation bag at 24 degrees C under air relative humidity of not greater than 70% in a cultivation room, and then culturing for 28-32 days, where the cultivation room is placed in dark; (vi) loading cultivation into the bag at 14-16 degrees C, under air relative humidity of 90-95% in the cultivation room, and then removing the cover from the cultivation bag, and then opening-bundled plastic sleeve ring, and cultivating for 17-19 days, and carrying out Pleurotus eryngii growing management for 9-10 days under diffusion light of 500-1000 1x in the cultivation room; and (vii) recovering Pleurotus eryngii.
