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.

Energy-saving heat preservation method of Pleurotus ostreatus
When the temperature is low in winter, the cultivation of Pleurotus ostreatus often produces bacteria slowly or not, even if it can produce mushrooms, abnormal mushrooms will be produced, and the cultivation cost of heating with coal stove is high, and it is easy to cause poisoning. Take the following measures to make full use of biological energy to keep the bacteria bag at a higher temperature, which can save the planting cost. Pleurotus ostreatus is inoculated and cultivated in bags in autumn, and half a bag of hyphae can be sent out when the temperature is cold. When such bags are cultivated in heat preservation, the bags can be quickly filled with hyphae. If it is not bagged in advance, it can be added at one time.

High quality cultivation of Pleurotus ostreatus in winter and spring imitating wild
The Pleurotus ostreatus produced by imitating wild cultivation technology can not only taste like wild delicacy, but also achieve high ecological quality and high yield. Even in the cold winter and low temperature in early spring, the high quality Pleurotus ostreatus can be produced by making full use of the ground temperature in the relatively closed shade shed. The yield of this method is more than 60% higher than that of conventional cultivation, more than 40% higher than that of bacterial wall and other cultivation methods, and the biological conversion rate is more than 220%. 1. Mycelium culture. The hyphae were sterilized under high pressure or atmospheric pressure and inoculated routinely to cultivate the hyphae that reached physiological maturity.

The production of Pleurotus ostreatus in winter and spring greenhouse should pay attention to the bad weather
In winter and spring, snow, cold snap, strong wind, long-term fog, continuous low temperature and other bad weather often come unexpectedly, light ones will reduce the yield and quality of Pleurotus ostreatus, and serious ones will cause no harvest of Pleurotus ostreatus. Therefore, we should strengthen the prevention and response to bad weather. The main preventive measures are to wipe the greenhouse film to improve the light transmittance, check the greenhouse facilities to ensure the thermal insulation performance of the greenhouse, and prepare thermal insulation items such as grass and old greenhouse film. Management measures: cold snap and gale cooling weather: before the cold current and gale comes, close the vents, cover the greenhouse film, and add it to the grass.

Interplanting Pleurotus ostreatus in rice field
During the growth and development of rice, interplanting Pleurotus ostreatus under the special conditions of rice row space and shade can not only provide suitable temperature and humidity conditions for the growth and development of Pleurotus ostreatus (large temperature difference between day and night, good shading, sufficient scattered light, etc.), and make Pleurotus ostreatus obtain high yield. it can also fill the market off-season with few mushrooms in summer, enrich summer vegetable varieties and increase the income of rice farmers. 1. Stubble arrangement and field design: Rice varieties should choose varieties with strong lodging resistance, plant height, culm diameter and resistance to rice planthopper. The sowing time is in late May and transplanting in late June, and the density is only

At present, the management of Pleurotus ostreatus should pay special attention to cooling.
Pleurotus ostreatus is mainly produced in winter, and at present, most of them have entered the second or third stubble stage. at this time, attention should be paid to the cooling of Pleurotus ostreatus: first, the natural temperature in spring is suitable for the growth of Pleurotus ostreatus, and people are easy to ignore the control of the temperature in the greenhouse and bag; second, the decline of mycelium vitality, high temperature will aggravate the speed of mycelium aging. The third is that Pleurotus ostreatus produces mushrooms quickly and neatly in spring, and the respiratory heat produced will cause a sharp rise in the temperature of the bag in a short time; fourth, to prevent the occurrence of yellow mushroom disease, which is easy to occur when it is more than 20 ℃. According to our investigation, yellow mushroom disease has appeared recently.

Main Diseases and Control techniques of Pleurotus ostreatus in North China
1 symptoms of soft rot 1.1 the surface of the culture material or mushroom body is covered with a layer of white woolly fungus, slender but growing fast, and the gradually infected mushroom body spreads light brown morbid from the base of the fungus, and the mushroom body gradually soft rot; about a week after infection, the mushroom body loses automatically or falls down with a gentle touch, just like Chinese cabbage with soft rot, but the soft rot mushroom body has no smell. The growth rate of the mushroom body which is not yet soft rot is very slow, and the bacterial cap is gradually yellowish, lifeless and not bright, which is obviously different from the normal mushroom body; the infected material is no longer infected.

The yield of Pleurotus ostreatus is doubled with the combination of bag cultivation and wall cultivation.
According to the experiment, using soybean straw as raw material, planting Pleurotus ostreatus by bag planting and wall planting can stabilize the biological transformation rate at about 200%, and the highest can reach 300%. The specific methods are as follows: to prepare the culture material, the fresh, dry and mildew-free bean straw was exposed to the sun for 2 or 3 days and crushed by a grinder with a sieve aperture of 1 cm. The formula is: soybean straw powder 78%, wheat straw 10%, soybean cake 5%, gypsum 1%, calcium superphosphate 3.5%, urea 0.5%, corn meal 2%, water 130%. Will cultivate

Rapid growth of Pleurotus ostreatus in bags
The mycelium of Pleurotus ostreatus usually takes 25-30 days to fill the bag after inoculation. The longer the inoculation time, the more chances of infection of miscellaneous bacteria, and the longer the production cycle. A simple and rapid method of producing bacteria is introduced below, which can significantly shorten the time of producing bacteria, reduce the pollution of miscellaneous bacteria, speed up the emergence of mushrooms and shorten the production cycle. After the culture material (clinker) is bagged, it is inoculated at both ends. At both ends of the bag, use a sharp rod (2-3 cm in diameter and about 30 cm in length) to drill holes in the center of the bag head, with a depth of more than half of the bag, and then insert an appropriate amount of bacteria into the hole.

How to cultivate Pleurotus ostreatus in greenhouse
Pleurotus ostreatus has the advantages of fast growth, strong stress resistance, a wide range of culture materials, convenient cultivation and management, and can be cultivated in four seasons. The cultivation of Pleurotus ostreatus is mainly in greenhouse in our province. The author has sorted out the cultivation techniques of Pleurotus ostreatus in greenhouse, which can be used as a reference for farmers. The main results are as follows: 1. varieties should be used in early spring, medium and high temperature varieties in late spring and early summer, and high temperature varieties in summer and autumn. 2. the middle temperature type varieties in the production season produce the original seeds from November to December and from January to February; the high temperature type varieties
