Winter planting mushroom should prevent deformity
Cultivation of Pleurotus ostreatus in winter, poor management is easy to produce a variety of abnormal mushrooms, reduce the commercial value, thus reducing the economic benefits.
The main results are as follows: 1. Bigfoot mushroom: after the occurrence of the primordium, the differentiation of the cap is not consistent with the rate of development, which is only long stalk, thick and thin at the bottom, but not long umbrella, and the diameter of the cap is smaller than the diameter of the stalk, which forms Bigfoot deformity.
Preventive measures: pay attention to ventilation and reasonable water spraying. Even if you encounter continuous low temperature weather, the mushroom production period should be controlled within the time of high temperature of the day, a short period of ventilation should be carried out, and water should be sprayed frequently, but not too heavy at one time.
2. Blue mushroom: during the growth of the mushroom body, a blue halo occurs on the edge of the mushroom cap, and even the whole mushroom body turns blue-black, which does not fade until harvest.
Preventive measures: it is better to use daylight, heating, electric heating and other methods to increase temperature. If firewood and coal are used to increase the temperature, closed heat transfer and smoke exhaust pipes should be installed, and it is not suitable to build the stove directly in the mushroom room.
3. Pleurotus ostreatus: tumor-like or granular protrusions appear on the surface of the cap, which is called blistering or wrinkling in the mushroom, and the growth of the bacteria is slow. In severe cases, the cap shrinks and the mushroom body stops growing.
Preventive measures: when planting Pleurotus ostreatus in winter, we must find out the lowest temperature that the cultivated varieties can withstand for normal growth and development, do a good job of heat preservation and temperature increase, and control the temperature of the mushroom bed. When adopting variable temperature stimulation measures, it should also be controlled within the suitable temperature range of mushroom body development, and the cooling process should not take too long. In general, the medium temperature type should be controlled above 8 ℃, and the low temperature type should be controlled above 0 ℃.

Measures to Prevent Deformity of Pleurotus ostreatus
In the production process of Pleurotus ostreatus, abnormal mushroom is easy to form due to inadequate management measures and inappropriate environmental conditions. In the production, we should find out the causes of abnormal mushroom formation and take effective control measures. 1. spherical or flasks: the stalk of Pleurotus ostreatus is spherical or flasks, the surface is uneven or twisted in waves, the cap cannot be formed, only a small point or obvious icicle stripes, which are caused by virus infection. Apply virus K, virus A, disinfectant spray or smear control. II. Cauliflower shape

Three precautions of planting Pleurotus ostreatus in winter
The ideal place for mushroom farm to be planted in winter is the mushroom farm with mild and heat preservation conditions, such as indoor mushroom room with warming conditions, underground mushroom farm with high temperature and Yangqi mushroom farm cultivated in plastic greenhouse, etc. The temperature of this kind of mushroom farm can be controlled above the normal temperature, so it is beneficial to the bacteria, and it can also set mushrooms earlier. Usually the outdoor mushroom farm can be chosen if the winter planting time is early, and the indoor mushroom house should be chosen if the winter planting time is late. According to the arrangement of mushroom production period, the strains of Pleurotus ostreatus can be divided into two types: winter planting in winter and spring planting in winter. The former chooses low temperature products.
