Planting techniques of Pleurotus eryngii cultivation time and method of Pleurotus eryngii

Pleurotus eryngii is a kind of food which likes temperature and dampness. at present, it is distributed in many parts of our country. For many people who want to grow Pleurotus eryngii, the first thing is to know the best time to grow it, and then the planting method. Only after in-depth understanding, it will be possible to grow Pleurotus eryngii with high yield.

Planting techniques of Pleurotus eryngii

1. The formula of cultivating materials. ⑴ sawdust 37%, cottonseed hull 37%, wheat bran 18.5%, corn meal 5%, gypsum 1%, white sugar 1%, lime powder 0.5%, pH 9-11. ⑵ cottonseed hull 78%, wheat bran 18%, sugar 1%, corn meal 2%, gypsum 1%, pH 9-11. ⑶ sawdust 23%, cottonseed hull 23%, wheat bran 18%, sugar 1%, gypsum 1%, corn meal 4%, bean stalk powder 30%, pH 9-11.

2. Make bags with ingredients. The above-mentioned culture materials are weighed in proportion, the ground of the mixing yard is turned and mixed evenly, and the water content is adjusted by 60% Mel 65%. Fill the material with 17 × 33 × 0.004 cm folded polyethylene bag or polypropylene bag, each bag contains 500g dry material, wet weight about 1100 g, diagonal reverse folding straight plug seal. After loading, put it into a large empty sterilization bag (self-made about 30 yuan, can hold 500 Mel 800 bags) for 4 hours and 5 hours, cool to room temperature and take out. For the aseptic inoculator of edible fungi for inoculation, two people cooperate with the full-open bag opening on the inoculation operation platform to access the bacteria, and each 750 g bottle of Pleurotus eryngii cultivation species can receive 40-60 bags. Keep the temperature between 20 ℃ and 25 ℃ and the air relative humidity above 70% after inoculation. Air is ventilated twice a day to keep the air fresh and the mycelium is full for about 30 days.

Planting time of Pleurotus eryngii

Under natural conditions, according to the suitable growth temperature of Pleurotus eryngii, it is generally suitable to be cultivated in autumn, winter and spring, but in areas with high winter temperature, it is better to arrange to produce mushrooms from December to February, because the temperature is too high or too low to form primordium. it is not conducive to the growth and development of fruiting bodies. Pleurotus eryngii is different from other Pleurotus ostreatus, if the head tide mushroom is not formed normally, it will affect the occurrence of the second tide mushroom and will inevitably affect the total yield. Therefore, the appropriate cultivation period should be arranged according to the suitable temperature for mushroom production in both the south and the north, and it is generally appropriate to make cultivation bags 50 days in advance when the local temperature drops below 18 degrees.

Planting method of Pleurotus eryngii

The method of burying bacteria bags. After the mycelium grows full of bacteria bags, it is moved into the vegetable greenhouse to bury the soil. The soil in the greenhouse is required to be loose and fertile. The most important feature of Pleurotus eryngii soil-covered cultivation is that the fruiting body is large, fresh and tender, and the yield is high. First of all, take off the bag, select the bag with no miscellaneous bacteria and good mycelium growth, break the bag with a knife, take out the bacterial mass completely, and then neatly lay it horizontally into the border bed, leaving a 2~3cm gap between the bags. Then fill the gap with sterilized clean fine soil, cover the whole bed with fine soil, spray clean water once, then cover the plastic film, and then cover the plastic film with straw. After the bacteria continued to grow for 15 days, when the soil was covered with Pleurotus eryngii hyphae, the film was ventilated and the temperature was maintained, which was beneficial to the formation of Pleurotus eryngii fruiting body. At the same time, certain light conditions are needed in the stage of mushroom emergence, so that after the fruiting body of Pleurotus eryngii is formed, there is no need to spray water within 7 days, strengthen ventilation and keep the air in the mushroom shed clean. Pleurotus eryngii usually takes 13 ~ 15 days from primordium formation to fruiting body maturity. The young mushroom grows slowly. When the mushroom body grows above 6cm, it is necessary to increase the humidity in the greenhouse and let the mushroom body be irradiated by scattered light. The relative humidity is 85%-90%, which promotes the mushroom body to form a normal fruiting body.

Management of mushroom emergence of Pleurotus eryngii

1. Humidity control: during the occurrence and growth stage of the fruiting body, the relative humidity in the mushroom room should be maintained at about 90% at the initial stage, and the humidity can be controlled at about 85% during the development of the fruiting body and when it is close to harvest, which is beneficial to prolong the shelf life of the fruiting body. At the same time, we should pay attention not to spray water on the mushroom body, especially when the temperature rises, spray water directly on the mushroom body, it is easy to make the fruiting body yellowing, and in serious cases, it will be infected with bacteria and cause decay.

2. Air conditioning: it is difficult for the fruiting body to develop normally with poor ventilation, and if it meets with high temperature and high humidity, it will cause the fruiting body to rot. Therefore, the mushroom room must maintain good ventilation conditions.

3. Control the light source: light is needed for the occurrence and development of the fruiting body, and it is appropriate to use 500 lux to 1000 lux. When the temperature rises, we should pay attention not to let the light shine directly.

There are two cultivation times for Pleurotus eryngii, that is, in autumn and winter every year, so friends who want to plant should make good use of these two periods. The planting technology of Pleurotus eryngii is relatively tedious, but every step can not be lacking, it needs to be cultivated carefully, so there will be a high-yield return.
