Key points of cultivation techniques for High quality and High yield of Pleurotus ostreatus

White jade mushroom, also known as imperial mushroom in Japan, is as white as jade, delicate texture and excellent taste, which is favored by domestic and foreign markets. Today, the editor of Tuliu.com will talk about the cultivation techniques of high quality and high yield of white jade mushroom.

First, cultivation time

According to the biological characteristics of Pleurotus ostreatus 5C~20C at low temperature, it can be cultivated in autumn and winter. For winter planting, sowing from December to February, mushroom from February to April, sowing from August to October in autumn, and mushroom from October to December, the suitable cultivation time should be determined according to different climatic conditions.

II. Preparation of raw materials

The practice shows that with the following culture materials, the mycelium grows fast, the fruiting body is large and thick, the quality is good, the yield is high, and the high quality cultivation formula is ① sawdust 76%, wheat bran 15%, corn meal 5%, gypsum 2%, lime 2%.

② cottonseed hull 50%, sawdust 30%, wheat bran 16%, gypsum 2%, lime 2%

③ crop straw 40%, sawdust 35%, wheat bran 18%, corn meal 5%, gypsum 1%, lime 1%

3. Bagging and sterilization

Double-set method is adopted for bagging, that is, 15 × 30 × 0.05cm polyethylene plastic bags are used inside, the culture materials are mixed evenly, sufficient moisture is added according to the material-water ratio of 1Ru 1.3, and the water content is adjusted by 60% to 65%. The bagging height is 16cm~18cm, and the wet weight of each bag is 650g ~ 750g, which is equivalent to 300g ~ 350g. Abandon the tedious process of conventional ring cotton stopper, fold the upper end of the bag diagonally, then cover it with a 17 × 33 × 0.05cm polyolefin bag and tie the bag mouth with rope.

IV. Inoculation and cultivation

After sterilization, it was moved to the inoculation room while it was hot, and the inoculation space was sterilized by aerosol disinfectant or formaldehyde mixed with potassium permanganate. When the temperature of the material dropped below 30C, the inoculation process was strictly in accordance with the requirements of aseptic operation to prevent miscellaneous bacteria infection. After inoculation, the bacteria bag was moved into the culture room to avoid light. Three days after inoculation, the germination and colonization of miscellaneous bacteria and strains were examined. During the mycelial culture, the air was often ventilated, the air was kept fresh, and the indoor temperature was controlled at 15C.

5. Management of mushroom production

1. Generally, after 30 to 40 days of culture, the hyphae grow full of bags and then continue to raise bacteria for 7 to 10 days, so as to promote the physiological maturity of hyphae. The mature bacteria bag was removed from the mushroom room to induce mushroom production.

2, specific operation: adjust the temperature of the mushroom room 5C~20C, open the film at night, open the doors and windows to give cold stimulation; open the grass curtain during the day to give light stimulation; and spray water on the floor and walls to increase the relative humidity of the mushroom room space 85% 90%. After 5: 7 days of repeated budding management, the bag mouth found that the white primordium is the size of soybeans, remove the bag mouth and tie the rope; when the broad bean size, open the bag mouth film When growing to the size of a ping-pong ball, cut the bag opening film to promote the differentiation of the bacterial cap. Prevent the occurrence of deformed mushrooms with long stalk and small cover

Well, these are the high-quality and high-yield cultivation techniques of Pleurotus ostreatus brought by the editor of Tuliu.com. If you like it, welcome to follow Tuliu.com.
