What are the key points for the management of Pleurotus ostreatus planted in winter
Pingru is cultivated in winter, the temperature is low, the mycelium grows slowly, once there is pollution, it is difficult to cultivate successfully.
The main points of winter management are:
The main results are as follows: (1) selecting good varieties: when the temperature is low in winter, we should choose low-temperature or wide-temperature varieties, such as mistakenly planted medium-temperature and high-temperature varieties, it is difficult to manage, and there are no mushrooms or abnormal mushrooms.
(2) suitable temperature bacteria: create suitable temperature conditions for bacteria generation. Due to the open cultivation of raw materials in winter, the content of miscellaneous bacteria in the materials is high, and there is a relationship of mutual inhibition (antagonism) between miscellaneous bacteria and Pleurotus ostreatus in the growth process. Only by ensuring the suitable growth temperature and exuberant growth of Pleurotus ostreatus can we effectively restrain the growth of miscellaneous bacteria and make use of our own advantages to control the pollution of miscellaneous bacteria.
(3) ventilation and moisturizing: if the climate is dry in winter, artificial water spraying should be strengthened to maintain the air relative humidity required by the fruiting body. However, due to the carbon dioxide produced by the respiration of bacteria and the carbon dioxide produced by heating by fire, the accumulation of carbon dioxide is formed, which affects the development of Pleurotus ostreatus. In order to solve the contradiction between heat preservation and ventilation, proper ventilation can be carried out by spraying water at noon every day, not only to ensure fresh air, but also to maintain a stable relative humidity.
(4) Scientific water spraying: it is strictly forbidden to spray water directly to the fruit body during the growth and development of the fruit body, and warm water can be sprayed 3 times a day. It is necessary to master "two more and two less", that is, most mushrooms are sprayed, less mushrooms are sprayed; spray more on sunny days and less on rainy days. In order to increase the relative humidity of the air, a water pot can be installed on the stove to satisfy the relative humidity with steam, or a wet cloth or strip of wet cloth can be hung indoors.

A simple heat preservation method for planting Pleurotus ostreatus in winter
The success rate of cultivating Pleurotus ostreatus in winter is high, and it is also a good opportunity for people to make use of their spare time to get rich. But how can Pleurotus ostreatus be cultivated in winter to create the right temperature? 1. Pleurotus ostreatus should be cultivated in late autumn. A Pleurotus ostreatus bag with half a bag of hyphae to keep warm when the climate is cold. two。 After the air temperature is very low, the bacterial bag is used to increase the temperature and keep warm. The method of stacking is: 4 rows into a section, each row of 7 bags, leaving a gap of about 5 cm between each row to facilitate air exchange. The distance between each segment is 67%.

How to prevent deformity of Pleurotus ostreatus
After the occurrence of the primordium of Pleurotus ostreatus, the differentiation and development rate of the cap was abnormal, which was characterized by small cap, long stalk, rough and hard stalk and low commercial value. The main reason is the adoption of closed heat preservation and cold protection measures, which leads to insufficient oxygen supply and loss of balance of nutrient transport in mushroom. Preventive measures: in case of continuous low temperature weather, when the mushroom shed adopts closed heat preservation and cold protection, we should pay attention to ventilation for a short time at noon, but do not blow the material surface directly in a strong wind to prevent the death of young mushrooms. When the blue mushroom body grows, the edge of the cap produces a blue halo.
