Perforated aeration is not difficult to cultivate Pleurotus ostreatus in summer
Summer temperature is higher, plastic bag three-dimensional cultivation of Pleurotus ostreatus often produces serious pollution, and even causes cultivation failure. Whether it can pass through the fungus barrier is the key to the cultivation of Pleurotus ostreatus in summer, and it is also the most worrying problem for mushroom farmers. Practice proves that perforating and aerating is an effective method to cultivate Pleurotus ostreatus in summer. 1. Perforation time is generally 3-5 days after sowing, when the mycelium turns white and germinates and begins to extend to the culture medium. If the hole is drilled too early, the hyphae have not germinated yet, and it is easy to contaminate miscellaneous bacteria; if the hole is drilled too late, the hyphae are lacking in the development period.

High-yield techniques of Pleurotus ostreatus cultivated in coarse sawdust fermentation material bag
At present, with the development of edible mushroom industry, the demand for raw materials is increasing. The price of fine sawdust in three northeastern provinces has soared in recent years, but coarse sawdust has become waste (such as coarse sawdust leaked from electric sieves on chippers and coarse sawdust crushed by branch shredders). The author uses the local rich coarse sawdust as the main material for fermentation to cultivate Pleurotus ostreatus, which is summarized as follows: 1 the tested strain Pleurotus ostreatus 2026 was introduced from Shijiazhuang High-tech Edible Mushroom Station in Hebei Province to provide mother species. The original seed is corn kernel medium, 99% corn kernels and 1% gypsum. Put the corn kernels

Summer Management of Pleurotus ostreatus planted in Spring
Pleurotus ostreatus sown in early spring, after entering summer, due to the increase of temperature and humidity, not only inhibit the formation of mushroom buds, but also conducive to the breeding and spread of diseases and insect pests, it is necessary to carry out summer management. First, choose a place with high terrain and convenient drainage, dig a ditch with a depth of 60 cm to 80 cm and a width of 50 cm, pat the four walls, sprinkle the ditch with lime powder, or spray 800 times the carbendazim solution with lime milk. If there are diseases and insect pests in the culture material, it should be treated first. For those who have been infected with miscellaneous bacteria, scrape off the contaminated area and use lime milk or 800

Preventive measures for deformity of Pleurotus ostreatus in winter
1. 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. 2. Pleurotus ostreatus: after the occurrence of primordium, the differentiation of cap is not consistent with the rate of development, which is characterized by long stalk, thick and thin bottom, no umbrella and bacteria.

Wild and High-yielding cultivation of Pleurotus ostreatus in Winter and Spring
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 cold winter and low temperature in early spring, we can make full use of ground temperature to produce thick, fresh and tender Pleurotus ostreatus in the relatively airtight 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 can reach more than 220%. The specific cultivation techniques of Pleurotus ostreatus in winter and spring imitating wild high yield and high quality are as follows: first, mycelia are cultured under high pressure or atmospheric pressure.

Storage and fresh-keeping Technology of Pleurotus ostreatus
Fresh Pleurotus ostreatus has high water content and crisp and tender tissue, which is easy to cause damage. If it is not preserved properly, it is easy to rot and deteriorate, causing losses to producers. The following are several storage methods of Pleurotus ostreatus: 1. Fresh storage: the storage time of fresh Pleurotus ostreatus at room temperature is greatly affected by temperature and air humidity. When the room temperature is 3 ℃-5 ℃ and the relative air temperature is about 80%, the fresh mushrooms can be stored for a week. As the temperature increases, so does the humidity. When the amount of mushrooms is small, Pleurotus ostreatus can be put in a jar with a small amount of cold water, and the cylinder mouth is tightly sealed.

Cultivation of Pleurotus ostreatus
Plastic bag cultivation is not only labor-saving and easy to manage, but also can make full use of mushroom room space, reduce diseases and insect pests, and is easy to be cultivated successfully. It is not only suitable for indoor cultivation, but also suitable for cultivation in plastic greenhouses, civil air defense fortifications and other places, but also can be put into rice fields, corn fields, vegetable fields and intercropping with rice, corn and vegetables. This is a new cultivation method widely used in recent years. 1. Specification requirements for plastic bags: choose plastic cylinders with thickness of 0.03-0.04 cm, width of 24-30 cm and length of 40-50 cm (double openings).

Salinization processing Technology of Pleurotus ostreatus
According to the results of previous studies, the physiological indexes of banana packaging during sealed storage are respiratory intensity less than 80 mg carbon dioxide / kg / hour, starch content not less than 9%, soluble sugar content less than 2%; carbon dioxide concentration in the bag is 5-7%, oxygen is not less than 1%, ethylene 1ppm is less than. Bananas are treated with antistaling agent and then sealed in a thin film bag, which can be preserved for a long time at room temperature. After storage, the banana ripens normally and has the unique flavor of the banana. Preservative and fresh-keeping of bananas are mainly related to pathology

Brine processing of Pleurotus ostreatus
Pleurotus ostreatus, also known as abalone mushroom, is a kind of edible mushroom, fresh food can also be processed into canned export, extremely rich in nutrition. The salt water processing of Pleurotus ostreatus has the advantages of simple operation, easy transportation and high economic benefit. The grade standard of Pleurotus ostreatus (divided into 2 grades) Grade 1 mushroom: grey in color, 3-12 cm in diameter, without stalk, individual with stalk not more than 1 cm. Delicate tissue, complete shape, no serious shrinkage and cracks on the edge of the mushroom umbrella, no sediment or other impurities, no diseases and insect pests, no atrophy and deterioration, no peculiar smell, no soaking water. Second level

Processing Technology of Pleurotus ostreatus
In addition to some fresh sales, Pleurotus ostreatus can also be processed and stored, which can be processed by many methods, including drying and salinization, which are briefly described as follows: 1. The drying method generally adopts shade drying, sun drying, drying and so on. Insolation is an economical and equipment-free method. It can also be dried in the shade or dried by the wind. However, this method is limited by weather conditions. The drying method is commonly used in production, build a drying room, the heat source can be charcoal fire or coal cake, drying with reference to the form of the drying building. The room is non-smoking and should be equipped with exhaust equipment. The initial temperature is controlled at about 35 ℃.
