New intensive cultivation techniques of Pleurotus ostreatus in Korea
Pleurotus ostreatus belongs to basidiomycetes subphylum, Umbrella order, Pleurotus ostreatus family, Pleurotus ostreatus genus. Rich in protein, sugar, vitamins, iron, calcium and 8 essential amino acids. Its mushroom meat is fat and tender, tastes fresh and refreshing, has high edible and health care value, and is favored by consumers. It is a mushroom with large production and consumption in South Korea. Because Pleurotus ostreatus is not easy to transport and keep fresh over a long distance, fresh mushrooms are rarely imported from abroad and are mainly produced in South Korea. Compared with the conventional cultivation of Pleurotus ostreatus, the bioconversion rate of Pleurotus ostreatus is lower, only 50%-80%.

Summer Cultivation Technique of High Temperature Pleurotus ostreatus
With the coming of summer, the temperature rises gradually and the edible fungi on the market decrease day by day. At this time, the cultivation of high-temperature Pleurotus ostreatus can obtain considerable economic benefits. Variety selection. The main characteristic of high temperature type Pleurotus ostreatus is high temperature resistance. Generally, varieties with high temperature resistance of 36℃ can be selected. The high temperature varieties commonly used now include 831, Shuangkao No. 3, etc. Planting methods. Summer cultivation is generally suitable for indoor cultivation, so it is easy to control humidity. Bed width 80~100 cm, layer spacing 60 cm, can be set up 6~7 layers, bed room

How to cultivate Pleurotus ostreatus at high temperature
Late spring and early summer is a good time to cultivate Pleurotus ostreatus. The planting quantity of high temperature Pleurotus ostreatus is relatively less because of high temperature and more diseases, but its price is 2-3 times higher than that in autumn and winter. The cultivation technology of high temperature Pleurotus ostreatus is difficult and the success rate is very low, so how to obtain high quality and high yield is a problem that mushroom farmers are more concerned about. In variety selection, many mushroom farmers failed to cultivate high-temperature Pleurotus ostreatus, mostly due to mistakes in variety selection. Some mushroom farmers do not figure out the temperature type of the variety and plant it casually. As a result, they cannot produce mushrooms or fail to produce bacteria because of the wrong temperature type, so they must have a good reputation.

Mite control measures of Pleurotus ostreatus in high temperature season
1. The distribution and damage of acaroid mites: this mite is a worldwide widespread species. In the production of edible fungi, acaroid mites often occur in the environment polluted by miscellaneous bacteria. Because of their activities, the miscellaneous bacteria are enlarged and the healthy fruiting bodies rot. Acaroid mites can also directly feed on the mycelium of Pleurotus ostreatus, resulting in yield reduction or even loss of harvest. Morphological characteristics: the adult length of male mite is 240 rain 320 microns, and the adult length of female mite is 350 rain 650 microns, the body is colorless, the legs and feet are yellowish to reddish brown, and the back end is obtusely round. More than enough

High temperature No. 9 Pleurotus ostreatus
High temperature No. 9 Pleurotus ostreatus. Characteristics of ⑴: high temperature species, superimposed, gray cap, dark gray when the temperature is below 20 ℃, stipe, white pleat, compact and compact, high commercial quality. Without infection of yellow mushroom disease and brown rot, the biological efficiency of Pleurotus ostreatus is about 150%. The suitable temperature of ⑵ was 6-38 ℃ and 12-36 ℃ respectively.

Covering sediment can cure mixed bacteria of Pleurotus ostreatus
Miscellaneous bacteria pollution often occurs in the process of Pleurotus ostreatus cultivation, especially in the high temperature season. Most of these miscellaneous bacteria are aerobic, resistant to high temperature and high humidity, and can be prevented by covering silt. the specific techniques are introduced as follows: 1. Control of miscellaneous bacteria of Pleurotus ostreatus planted in bed. When Pleurotus ostreatus is contaminated by miscellaneous bacteria in big bed cultivation, the cause of pollution should be found out first. The common causes are sudden high temperature, water inflow into the material, unclean surrounding environment, insect pests and so on. According to the specific situation, remove the pollution source, and then treat the contaminated Pleurotus ostreatus as follows: sporadic miscellaneous bacteria on the material surface, use thick lime.

Control of miscellaneous bacteria of Pleurotus ostreatus by covering charred mud ash
Bed cultivation of Pleurotus ostreatus when Pleurotus ostreatus is cultivated in bed, if miscellaneous bacteria occur sporadically on the material surface, the miscellaneous bacteria can be removed by smearing or covering the affected area with thick raw lime mortar; if a large number of miscellaneous bacteria are produced on the material surface, the contaminated part can be covered with coke mortar 2m / 3cm thick, the coverage should be larger than the pollution surface, and the miscellaneous bacteria can be removed by tapping a little tightly. If the material surface is seriously contaminated by miscellaneous bacteria, cover the whole material surface with coke ash and clap tightly, the hyphae can return to normal growth after a few days. Bag cultivation of Pleurotus ostreatus first picked out the bags contaminated by miscellaneous bacteria, and then compared the terrain.

Control of soft rot of Pleurotus ostreatus
The disease is caused by Dactyliumdendroides infection in the subphylum Pleurotus ostreatus, also known as dendritic whorl mold, cobweb mold, etc., which is a harm to the soft rot of Pleurotus ostreatus fruiting body. (1) pathogenic characteristics and harmful symptoms: pathogenic hyphae are white, aerial hyphae grow exuberantly and densely, cotton-like; conidiophores grow directly from aerial hyphae, slender and sparse; conidiophores are verticillate and apical, solitary or clustered.

Control of soft rot of Pleurotus ostreatus
1. Fresh cottonseed hulls or corncob should be selected as raw materials for culture material treatment. Before mixing the material, you should expose it in the sun for 3 days, or use ultraviolet light to kill some of the miscellaneous bacteria in the culture material. When fermentation, the fermentation process should be strict, so as to be comprehensive, uniform and thorough. Products such as warming starter, Lixin fungus king or Cladosporium king can be added to improve the ability of resistance to miscellaneous bacteria. two。 When large bags of mushrooms are cultivated during the bacteriological period, they should be placed in a cool, ventilated and clean place. Try not to cultivate in the mushroom house (shed) to avoid breeding a large number of miscellaneous bacteria in the process of mycelium culture.

Measures to Prevent Deformity of Pleurotus ostreatus
In the production process of Pleurotus ostreatus, abnormal mushroom is easy to form due to inadequate management measures and inappropriate environmental conditions. In the production, we should find out the causes of abnormal mushroom formation and take effective control measures. 1. spherical or flasks: the stalk of Pleurotus ostreatus is spherical or flasks, the surface is uneven or twisted in waves, the cap cannot be formed, only a small point or obvious icicle stripes, which are caused by virus infection. Apply virus K, virus A, disinfectant spray or smear control. II. Cauliflower shape
