Preventive measures: a. Greenhouse cultivation density should not be too large, should pay attention to regular ventilation and light transmission; b. Avoid watering plants and avoid splashing water droplets

Mushroom series food processing
Mushrooms are rich in nutrition, delicious in taste, have the laudatory name of "meat in vegetarian", and have high health care function. The annual output of mushrooms in China ranks second in the world, and the export volume of canned mushrooms reaches 140000 tons, ranking first among the exporters of mushroom products in the world. In the past, the processed products put on the market were limited to dried mushrooms, salted mushrooms and canned mushrooms, and the variety was monotonous, which affected the export rate. Therefore, it is necessary to develop new varieties of mushrooms and expand the market. Four new varieties of processing methods are introduced below. (1) processing methods of mushroom pickles

Mushroom soil fertilization can increase yield.
In order to increase the yield of mushrooms, fertilizer must be applied properly. According to the practice of mushroom farmers in many places over the past few years, it has been proved that the following nine soil methods of fertilization will have a good effect on increasing production. Mushroom soup. Wash the mushroom feet and chopped mushrooms in harvesting and processing, cut into thin slices, add 1.5 kg of water per kilogram of material, boil for 15 minutes, dilute the filtrate and water to 10 Mel 15 kg, spray the mushroom bed 30 Mel 40 square meters. Use during peak mushroom production

Prevention and control of dead mushroom
The reason for the death of mushroom (1) the growth of young mushroom is weak. After the mushroom bed is covered with soil, the mycelium grows too fast, the mushroom position is too high, and the young mushroom is too dense, which leads to the death of some young mushrooms with insufficient nutrition supply. (2) too high temperature. When the temperature is above 21 ℃ for several days during mushroom emergence, the young mushrooms will shrink and die due to heat injury. (3) excessive humidity. The relative humidity of the mushroom room is more than 95% at high temperature. if the doors and windows are closed after spraying water at this time, and the surface of the mushroom bed is waterlogged, the young mushrooms will suffocate to death. (4) poor ventilation. Oxygen in mushroom room

Prevention and Control techniques of Mushroom death Disease
Dead mushroom refers to the phenomenon that the small mushroom on the mushroom bed shrinks, yellowes and dies. Mushroom wilt appears in pieces or in batches, which will seriously affect the yield. 1. The cause of mushroom death: the temperature of ① at the end of autumn was too high (more than 23 ℃), and the temperature rose too high and too fast during the spring emergence period (21 ℃ for several days in a row), resulting in the shrinkage and death of young mushroom seedlings due to lack of nutrition. ② mushroom room is poorly ventilated, O2 is insufficient, the concentration of co2 is too high, and the heat generated by metabolism can not be released quickly, which will make the young mushroom seedlings die in batches due to insufficient oxygen supply or high temperature. three

Mushroom double "show"
The Horticultural Research Institute of the Provincial Academy of Agricultural Sciences adopted single spore hybridization, single spore system selection and molecular assisted breeding techniques to develop a new brown Agaricus bisporus variety with low temperature tolerance, high quality and high yield, "Nangxiu No.1" and a new white Agaricus bisporus variety "Yingxiu No.1". It has been recognized by the first batch of edible mushroom varieties in the whole country. "Nangxiu No.1" is a new variety of brown Agaricus bisporus, with natural brown cover surface and white mushroom stalk and flesh. The mushroom quality is excellent, the fruiting body is round, the mushroom cover is thick, strong, not concave; the taste is delicious and tender. Because the mushroom cover is naturally brown, there is no need to make
