Mushrooms appear on the side of the bag and there are many deformities
In the process of sterilization, the bacterial bags squeeze each other and the round bags are deformed, resulting in a gap between the cultivation material and the bag, which provides air and space for the twisting of hyphae. Coupled with low temperature, light stimulation and mechanical stimulation (such as inverted bag, etc.), the hyphae on the side of the bag were twisted to form primordia and developed into fruiting bodies. Due to the limitation of plastic bags, this kind of mushroom is all deformed. If this happens, the mushroom bud should be pinched in time to stop its growth, so as not to cause more waste of nutrition. The fruiting body is small and the commodity rate is low:

Common diseases of Pleurotus ostreatus and their control
Pleurotus ostreatus is a kind of rare mushroom product which is very popular in domestic and foreign markets in recent years, but due to the occurrence of many diseases and insect pests, the growers often fail to accurately identify symptoms and pathogens, and blindly use chemical pesticides to treat the mushroom body, resulting in the damage of mushroom body. the cultivation benefit is poor. The symptoms, pathogens and control measures of common infectious diseases are introduced as follows: first, the fruiting body of brown rot stops growing, the cap and stalk rot, and stinks. The pathogen is Alternaria verrucosa, which is mainly caused by the transmission of contaminated water or contact with hands and tools of diseased mushrooms.

Six key points for High yield and High quality cultivation of Pleurotus ostreatus
Golden Pleurotus ostreatus, also known as Lobayi mushroom, large white mushroom, known as white matsutake in Japan, is a rare edible fungus that leads the market in summer. Its fruiting body is clustered, thick, thick, fresh and white, crisp and tender meat, excellent flavor, rich nutrition, known as the outstanding among the mushrooms with excellent taste and quality. in addition, it is especially favored when it is on the market when there is a shortage of mushrooms in summer. In Shanghai, Guangzhou, Hangzhou and other places, the price per kilogram of fresh mushrooms is 14,18 yuan, the benefit is very considerable, is a very promising rare mushroom species. The following introduces the "six keys" for the cultivation of high yield and high quality of Pleurotus ostreatus

Harvest of Pleurotus ostreatus
Pleurotus ostreatus is larger than ordinary edible mushroom. The average edible mushroom weighs about 10 grams, while the mushroom weighs about 60 grams. The heaviest mushroom can reach 2500 grams, with a diameter of 540 centimeters. It should be harvested in time according to maturity and market demand. It takes about 10 days for the fruiting body to mature from budding, that is, from the white spot to maturity, and the performance varies with different temperature. The growth rate is slow at low temperature, but the mushroom body is thick and it is not easy to open the umbrella. On the contrary, in high temperature, the flower shape is small and easy to open the umbrella. Three tides can be collected during the whole growing period.

Four methods of trapping and killing Mushroom mites
1. Rapeseed cake trapping method: spread several pieces of wet cloth on the bed where mushroom mites are harmful, and put gauze on the wet cloth. Sprinkle the freshly fried rapeseed cake powder on the gauze, wait for the mushroom mites to gather the gauze, remove and scald to death with boiling water. 2. Sweet and sour trapping method: mix 1kg of vinegar with 1kg of water, add 10g of sucrose, drop dichlorvos, mix well, soak the gauze in the mixed sweet and sour solution, and then spread the gauze on the mushroom bed to trap and kill mushroom mites. 3. Pig bone trapping method: fresh pig bones are placed apart on the bed to trap mushroom mites.

Causes and control of dead mushrooms in the cultivation of Agaricus blazei Murrill
Agaricus blazei Murrill (Agaricusblazei-murrill), also known as Brazilian mushroom, has developed rapidly in artificial cultivation in the past two years. Agaricus blazei mushroom shrinks, turns yellow and finally dies in Agaricus blazei Murrill cultivation. The main reasons are as follows. In view of the reasons, timely measures can be taken to avoid causing greater losses. The main results are as follows: (1) the high temperature of the mushroom shed is more than 30 ℃ for several days, coupled with poor ventilation, it is easy to cause dead mushrooms. Prevention and control measures: pay close attention to the change of air temperature during the mushroom period

Pleurotus ostreatus on top of mud mushroom
Symptoms: it mainly appears in the early stage of mushroom emergence, the fruiting body is low, usually occurs in the culture material, the material surface or the lower part of the coarse soil layer, and breaks the top of the soil when it grows up. The causes are as follows: 1. When the temperature, humidity and air conditions in the culture material are suitable for fruiting body growth, the mycelium will kink around the soil to form a primordium. After the primordium differentiation, it grows upward and comes out of the top mud. If the upward conditions are not suitable, it will turn around and grow under the bed to form bed mushrooms. 2. The water transfer time of coarse soil is too long, and the mushroom house is ventilated after water transfer.

Production techniques of plane cultivation and subculture of Pleurotus ostreatus
Pleurotus ostreatus has a broad development prospect in Shandong Province because of its strong growth potential, good stress resistance, easy cultivation and popularization, high biological efficiency and so on. Shandong Province is a major cotton planting province, and the planting area of cotton has increased in a straight line in recent years, and the cottonseed shell is of high quality and low price. Now the cottonseed shell is used as the main material, the plane cultivation of fermentation material is adopted, and the production technology of subculture of Pleurotus ostreatus is introduced as follows. 1. Strain production 1. Select strains with strong growth potential, good stress resistance, high and stable yield and wide temperature range, such as Yuhuang.

Causes and Prevention of Pleurotus ostreatus
Pleurotus ostreatus grows between the bottle wall (culture bag) and the culture material, the mushroom body is generally small and has no commercial value, but the mushroom absorbs a large amount of nutrients and water in the process of growth, so that the fruiting body on the surface of the cultivation bag can not grow normally or grow slowly. in serious cases, the surface of the cultivation bag does not form a fruiting body primordium. The main reasons for the formation of attached mushrooms are as follows: the culture bag is too loose or uneven, there is a gap between the culture bag (bottle) and the culture material, the water content of the culture material is low, the bacteria tube shrinks, and the gap is formed between the culture bag (bottle) and the material.

Bag planting method in mushroom house (shed)
1. Cultivation site and setting. Bag cultivation adopts the layer shelf cultivation method of mushroom house (shed). Choose a clean and ventilated room with 4-5 beds with a distance of 50 cm and the ground floor 30 cm from the ground. The single layer of bacterial bag is vertically placed on the shelf, and 100 bags are discharged per square meter. two。 Cultivation raw materials and formulations. (1) 23% sawdust, 23% cottonseed hull, 28% bean stalk powder, 19% wheat bran, 5% corn meal, 1% sucrose, 1% calcium carbonate; (2) 36% sawdust, 25% cottonseed hull, beans
