Edible fungi should be heated up and moisturized when overwintering.

December is the busiest time for the production of edible fungi, most of the cultivated varieties are producing mushrooms, some of them are emerging in spring, and some strains are being produced or in the process of producing fungi. In December, the temperature drops, which is a big test for the growth of edible fungi. Therefore, mushroom farmers must make reasonable arrangements and do a good job of management to ensure the normal growth of edible fungi.

Most of Pleurotus ostreatus are in the stage of mushroom emergence, and some of the cultivation in autumn has entered the end of mushroom production. The focus of management is heat preservation to solve the contradiction between heating and moisturizing and ventilation in the mushroom shed. For strains with wide temperature type, such as 8359, Agricultural 12, etc., the greenhouse temperature should be kept at about 15 ℃. Using low temperature strain such as 2006 and Tekang 1, although the fruiting body will not freeze to death under the condition of 0 ℃, the growth rate is too slow to catch up with the golden period on the market. Therefore, we should try to keep the greenhouse temperature at about 10 ℃. Ventilation is the biggest problem in this period, and it is a serious contradiction with heating and moisturizing, which should be coordinated according to the actual situation.

Most of Flammulina velutipes are in the stage of producing mushroom or about to produce mushroom. Due to the characteristics of Flammulina velutipes, the management of Flammulina velutipes is relatively simple, as long as the temperature is kept at 4 ℃ ~ 15 ℃ and the humidity is kept at suitable conditions, a good harvest can be obtained.

Lentinus edodes is the top grade of Lentinus edodes. To cultivate Lentinus edodes, keep dry and bright light in the shed, and the humidity should not exceed 70%. In particular, it should be noted that once the young mushrooms bloom, the humidity should never rebound, otherwise "camellia mushrooms" will be formed. reduce the commodity. If you encounter high wet weather such as rain, snow and fog, you can reduce the humidity by burning a coal stove in the shed, but pay attention to discharge the smoke outside the shed, otherwise, it will cause sulfur dioxide in the product to exceed the standard and become toxic food. When cultivating thick mushrooms, we should pay attention to ventilation, maintain humidity, according to the market and other conditions, can reduce the temperature, make it grow into thicker fresh mushrooms, and maximize its commercial value. In winter, the cultivation of water mushrooms is not recommended.

It is difficult for Pleurotus ostreatus to produce mushrooms below 10 ℃, and the key point of management is heating and moisturizing. Once the temperature is lower than 8 ℃, it is not possible to produce mushrooms. Due to the small number of fruiting bodies of Pleurotus ostreatus, the demand for oxygen is small, so the ventilation rate can be reduced.

Pleurotus ostreatus, hericium Erinaceus and other varieties, heat preservation should be the first focus of management, followed by ventilation. It should be managed according to the varieties and different stages of mushroom production, not across the board.

Some of the varieties listed by New Year's Day to the Spring Festival are in the late stage or post-ripening stage of mycelium, such as Pleurotus ostreatus, Flammulina velutipes, hericium Erinaceus, tea tree mushroom, etc., the focus of management is heat preservation, combined with appropriate ventilation measures, the bacteria can be successfully completed.

Lentinus edodes, Coprinus comatus and Pleurotus ostreatus, which produce mushrooms in spring, are in the initial stage of bacteria, heat preservation can be kept, and there is no need for too much management, but we should pay attention to the fact that the bacterial bags are covered with thermal insulation materials, not to be inspected for a long time, otherwise, once burning occurs, it will be too late to regret.
