A New Technique for Anti-fouling of Mushroom in Bag Cultivation
In addition to the complicated technology, low production technology and simple conditions, the bag cultivation of mushroom is easy to cause pollution. It is also related to the quality of raw materials, strains and plastic bags, extensive production and management, single disinfection and control effect of pure chemicals for a long time, and drug resistance of miscellaneous bacteria. In order to effectively solve the pollution problem: 1. The preparation of culture medium can adopt conventional sawdust, bran, cottonseed hull, corncob and crop straw culture medium formula. The ratio of material to water is 1.0:(1.2~1.

Rapid budding technique of Lentinus edodes planted in bags
Bag cultivation of Lentinus edodes with water injection or bubble bag method will make the water content in the stick too high, and the mushroom farmers have been busy cutting the bag film to protect the mushroom buds for a long time. Some do not produce mushrooms for a long time, miss the cultivation season of flower mushrooms, and affect the yield, quality and efficiency. In this paper, a set of rapid bud induction method is introduced. Directional piercing hole: four iron nails with a length of 10cm are used, which are 1.5 cm thick, 45cm long and suitable for hand-held wood. All the nails should be inserted. Stab two rows of dough on the mushroom stick with nails, 2 rows and 8 eyes on one side. Vertical type

Common physiological diseases of Lentinus edodes with bag material
Physiological disease, also known as non-infectious disease, is a phenomenon of poor growth caused by unsuitable growth conditions or the influence of harmful substances in the environment. Although this disease has no pathogen and will not be transmitted to each other, it will cause heavy losses once it occurs. The most common physiological diseases of Lentinus edodes in Chunhua bag in Shaanxi Province are mycelium desalination, burning bacteria (stuffy pile), yellow water, decay and deformed mushroom and so on. 1 mycelium desalination 1.1 symptoms: mycelium growth was sparse and rods were soft and inelastic. 1.2Etiology: the culture material of ① has become moldy before sterilization.
