The latest course on planting techniques and methods of Pleurotus eryngii

Pleurotus eryngii, also known as Pleurotus eryngii, is a new rare edible mushroom variety successfully developed and cultivated in recent years, which integrates edible, medicinal and dietotherapy. Pleurotus eryngii belongs to low-temperature strains. It takes about 50~60 days from sowing to fruiting. The Yangtze River Basin can arrange cultivation bags from October to November, and fruiting from November to January of the following year. Other areas can be appropriately advanced or delayed. Let's take a look at the cultivation techniques of Pleurotus eryngii together.

planting material

There are many matrix raw materials suitable for the growth of Pleurotus eryngii, such as miscellaneous sawdust, cotton seed shell, waste cotton, bagasse, wheat straw, bean straw, etc. can be used as main materials, in order to prevent puncture cultivation bags and easy to mix materials bagging (bottle), sawdust must be sieved, straw must be crushed.

the adjuvant can be bran, rice bran, corn flour, cottonseed cake pow, calcium carbonate, white sugar, gypsum powder, etc.

cultivation methods

The cultivation of Pleurotus eryngii has different cultivation containers, such as bottle cultivation, box cultivation and bag cultivation, among which the most convenient and practical is bag cultivation.

The procedure of bag cultivation is: preparation of strains (including mother seeds, original seeds and cultivated seeds) → preparation of cultivation bags (including preparation, ingredients, bagging and sterilization) → fruiting management → harvesting and processing.

culture season

Under natural conditions, according to the suitable growth temperature of Pleurotus eryngii, it is generally suitable to cultivate in autumn and winter, but in the area with higher winter temperature, it is better to arrange the fruiting in December to February, because the temperature is too high or too low to form the primordium, which is not conducive to the growth and development of fruiting bodies. Pleurotus eryngii is different from other pleurotus ostreatus. If the first tide mushroom does not form normally, it will affect the occurrence of the second tide mushroom, which will inevitably affect the total yield.

Therefore, whether in the south or north, the appropriate cultivation period should be arranged according to the appropriate temperature for mushroom production. Generally, it is advisable to make cultivation bags 50 days in advance when the local temperature drops below 18 degrees.

Culture preparation

1. Mother species

Common media are PDA or PSA. MGYA medium (1000ml for example: peptone 1g, maltose 20g, yeast 2g, agar 20g), PDYA medium (1000ml for example: peptone or soybean peptone 1g, potato 300g, agar 20g, glucose 20g, yeast 2g), malt extract medium (1000ml for example: malt extract 20g, agar 15g, peptone 5 g) can also be used. According to the conventional method, it takes 8~10 days for hyphae to grow completely in tube. The growth speed of hyphae can be accelerated by using the last three media.

2. Original and cultivated species

The culture medium formula is the same, but sawdust bran culture medium can be adopted, and its formula is sawdust 73%, bran 25%, sugar 1%, and calcium carbonate 1%. Grain such as wheat, barley, corn and sorghum can also be used as culture medium. According to the conventional method, ingredients, treatment, bottling (bag), sterilization, inoculation, culture, the first medium generally takes 30-35 days to grow hyphae full bottle (bag), with the latter several grain media, hyphae full bag (bottle) faster, about 20 days.

cultivation site

Pleurotus eryngii is cultivated in the layer frame of mushroom house. The mushroom bag is arranged vertically in single layer. The bed frame is 50cm apart. The bottom layer is 30cm above the ground. The bed frame is usually 4~5 layers. The practical area of mushroom house is % 26 I uml. 60%%26Iuml。Bed frame layers, such as mushroom room 40m2%26Iuml. 60%%26Iuml。4-layer shelf =96m2, 100 bags can be discharged per 1m2, and the mushroom house can cultivate 9600 bags.

Mushroom to set ventilation windows, can open and close, there is a certain amount of scattered light and can avoid direct sunlight. Mushroom farm near water, convenient transportation, north-south, clean environment, no pollution sources.

Cultivation material formula

Cultivated material formula, local selection can be prepared according to local conditions, are listed several formulas for selection.

1. Mixed sawdust 36%, cottonseed hull 38%, bran 24%, white sugar 1%, calcium carbonate 1%.

2. Mixed sawdust 23%, cottonseed hull 23%, bran 19%, corn flour 5%, bean stalk powder 28%, calcium carbonate 1%, white sugar 1%.

3. Mixed sawdust 23%, cottonseed hull 38%, bean stalk powder 15%, bran 17%, corn flour 5%, calcium carbonate 1%, white sugar 1%.

4. Mixed sawdust 37%, cottonseed hull 38%, bean stalk powder 15%, bran 17%, corn flour 5%, calcium carbonate 1%, white sugar 1%, lime powder 0.05%.
