Eight Prevention measures of bag material Lentinus edodes safe over Summer
According to the investigation and analysis of the over-summer problem of bag material Lentinus edodes cultivation in Xixia for more than ten years, we summed up a set of bag material Lentinus edodes safe summer prevention measures, which are introduced below for reference. 1. There are many factors that prevent bacteria from containing miscellaneous bacteria, such as incomplete sterilization of culture materials, lax disinfection of inoculation links, introduction of bacteria in inoculation operations, air squeezing in cotton plugs, strain transport, respiration or injury, access to miscellaneous bacteria containing bacteria and other reasons for production, there will be latent and inestimable losses. 1.1

Control methods of competitive mixed bacteria of Edible Fungi
1. The harmfulness of competitive miscellaneous fungi in the production process of edible fungi, due to large-scale cultivation or production in the same place for many years, edible fungus diseases and insect pests and miscellaneous bacteria often occur, which spread quickly and lose a lot, which has become a major obstacle to the development of edible mushroom production. Among them, competitive miscellaneous bacteria, such as bacteria, Trichoderma, Mucor, Rhizopus, Aspergillus and Streptomyces, often occur, infect the mycelium of edible fungi, grow fast, compete for nutrients of culture materials, secrete toxins, and inhibit the normal growth of edible fungi mycelium.

Cultivation of Pleurotus ostreatus: how to do with miscellaneous bacteria pollution?
How does tea tree mushroom miscellaneous bacteria pollution do? Is there any way to prevent and cure the cause of miscellaneous bacteria pollution of Pleurotus ostreatus: the contamination rate of Pleurotus ostreatus bags is higher than that of other mushrooms, the main reason is that the cultivation quantity is larger, the average grower makes no less than 5000 bags at a time, more than 10, 000 bags, heavy workload, mixing, bagging, sterilization, receiving.

A simple and rapid method of producing bacteria in Pleurotus ostreatus production bag
Bag cultivation of Pleurotus ostreatus usually takes 25 to 30 days after inoculation before the mycelium can fill the bag. The longer the time of infection, the greater the probability of infection of miscellaneous bacteria, and the longer the production cycle. In order to shorten the time of collecting bacteria and improve the economic benefit, this paper introduces a simple method of rapid bacteria distribution in Pleurotus ostreatus production bag. In the center of the two ends of the Pleurotus ostreatus bag, the hole is punched with a sharp rod with a diameter of 2 cm to 3 cm and a length of 30 cm, and the depth of the hole is more than half of that of the bag. Then put an appropriate amount of bacteria into the rod hole, and put more than the conventional inoculation amount on the material surface at the end of the bag.

How to plant green head bacteria artificially? Can the green head fungus be eaten raw? how much is it per jin?
Green head bacteria and double positive bacteria are pure natural strains, because the growth of green head bacteria depends on the nutrients of termite nests and has high requirements on the environment, so it is not possible to cultivate individuals for the time being. The growth period of green head bacteria is in summer and autumn every year, and it generally produces more after rain. Green head

Cultivation of Lentinus edodes by artificial inoculation
If it is suitable for drying, Lentinus edodes should be inoculated in time. The inoculation time is generally more than 5 ℃, less than 20 ℃, and the monthly average temperature is about 10 ℃. In the south of the Yangtze River in China, Lentinus edodes was inoculated from late February to early April, and the most suitable period was from February to mid-March. There are sawdust bacteria, branch bacteria and wedge-shaped bacteria, and sawdust bacteria are used in most domestic wood cultivation. The high quality pure strain of Lentinus edodes, the mycelium is white and dense, has the unique fragrance of Lentinus edodes, the aerial mycelium has the ability to climb the wall, and the mycelium in the culture medium has no miscellaneous color and obvious inhibition line.
