Answers to questions about the cultivation of Pleurotus eryngii

How to arrange the planting time of Pleurotus eryngii?

Answer: according to the temperature requirement of fruit body differentiation of Pleurotus eryngii at 14-18 ℃, the suitable bag-making time in low altitude areas of our city should be arranged from late September to mid-October, and from early September to the end of September in areas above 700m above sea level.

How to prepare the culture material of Pleurotus eryngii?

Answer: 42% sawdust, 36% cottonseed hull, 20% wheat husk, 1% sugar, 1% calcium carbonate; water content is controlled between 60% and 62%; pH6-6.5.

How to manage Pleurotus eryngii during the period of culture?

A: the temperature is controlled at about 24 ℃ and the air humidity is controlled at 60% Rue 65%. There is no need for light during bacteria removal, and ventilation is required for 1-2 times a day, 0.5-1 hour each time.

How to manage the production of Pleurotus eryngii?

When the bacterial bag has been cultured for 40-50 days and the temperature has stabilized below 18 ℃, the mushroom production management can be carried out. At this time, the temperature should be controlled at 16 ℃, the humidity should be increased to 85% Mui 90%, it is necessary to use 500 lux light to accelerate the bud, when the mushroom bud grows to about 2cm, then take off the bag, cut the mouth of the bag to level with the material surface, or fold it down by 1/3, and cover it with non-woven cloth to maintain the appropriate temperature and humidity of mushroom production, so that the fruiting body can grow normally.

How to control diseases and insect pests of Pleurotus eryngii?

Answer: the diseases and insect pests of Pleurotus eryngii should give priority to prevention and clean the environmental hygiene of the training room. During the period of growing mushrooms, proper alternating management of dry and wet should be carried out. When diseases occur, they can be sprayed with 500 times carbendazim and insect pests, and can be prevented by Mushroom Chongjing and dichlorvos when the tide changes.

At present, the production of secondary bacteria of Pleurotus eryngii in various places in autumn has been completed, and the production of cultivation bags is about to begin. The autumn mushroom production period had better be on the market before August Festival and National Day so that it can be sold at a good price. How to produce mushrooms early has become an issue of concern to every grower. After many cultivation practices, the author summed up the following methods to accelerate the growth of mycelium:

1. Less loading. The normal loading height of 17-33cm corner bag is 18-19cm, which can be adjusted to 14-15cm height.

2. Punch a big hole. The diameter of the punching rod in the bag is 2.5-3cm. After the vent is full of bacteria, there is a layer above it, so that it grows both inside and outside.

3. Loosen the cotton stopper. After the mycelium eats 1 stroke 3, loosen the cotton plug to enhance the oxygen supply capacity.

Through the above treatment, the mycelium can be shortened from about 40 days to 25-30 days.
