Winter planting mushroom should prevent deformity

Last Updated: 2024/11/06, In winter, cultivation of Pleurotus ostreatus, poor management is easy to produce a variety of abnormal mushrooms, reduce commodity value, thereby reducing economic benefits. 1. Bigfoot mushroom: After the primordium occurs, the differentiation of the cap is inconsistent with the development speed, showing that only the mushroom stalk is long, the lower part is thick and the upper part is thin, and the mushroom umbrella is not long. The diameter of the cap is smaller than the diameter of the stalk and forms bigfoot deformity. The stalk of this mushroom is hard and the commodity value is low. Preventive measures: do a good job of ventilation and reasonable water spray. Even in the case of continuous low temperature weather, the mushroom production period should also be mastered in a day when the temperature is relatively high, and ventilation for a short time should be carried out.

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 ℃.
