Rice grains are more suitable for the cultivation of edible mushrooms

The original species and cultivated species of edible fungi are commonly used as cotton hulls or sawdust, and a few of them use granules such as wheat granules or corn granules, and liquid strains are used for industrial production. In fact, the use of rice granules in the production of edible fungi is more effective. First, the production methods of rice granules rice soaked with water for 48-60 hours to suck enough water, with water or artificially prepared nutritional water, boil until rice cooked without flowering. Dry the filter and dry it, dry the surface moisture, add 1%-3% gypsum powder and mix well. Load saline or plastic bags, no more than half bottles or 1/3 bags. The brine bottle is sealed with a tampon and the plastic bag is folded and sealed. It was autoclaved at 121-125°C for 2 hours and then allowed to enter the bacteria after cooling. When the strains germinate and grow to about 10 grains of rice per group of bacteria, shake the bottles or pour the bags and shake the granules apart. Continue to culture and shake again when forming 10 or so lumps. Before each shaking or pouring the bags, pick out the bacteria with bacteria. Repeat this 4-5 times until all the rice is covered with hyphae. Second, the advantages of rice granules compared with wheat or corn granules Since rice has a husk, it is easy to master the degree of ripeness without flowering when boiled. Plastic bags of rice grains, even if the bag is not timely, the bacteria form a block, you can also squeeze smashing, and the damage of the mycelium in the stalk is not very large, but has become a group of wheat or corn particles are very Difficult to get into a single particle. Third, the advantages of rice grains compared with cotton hull or sawdust original species, cultivars 1. Cotton husks or sawdust original species are covered with hyphae and become lumpy. When used, they are not easily crushed, and the inoculation rate is slow. When the cultivar was crushed, the mycelium was seriously injured, the mycelium germinated slowly after inoculation, the feed was slow, and the contamination rate was high. Rice granules are often shaken when cultured, so that they are not easily caked and dumped directly when used. The inoculation rate is fast and the mycelia growing in the husks are not easy to be injured. After inoculation, the mycelium germinates quickly, eating fast, and the authenticity rate is high. 2, wood chips or species of cotton hull often due to bacteria in the inspection is not timely and cover the bacteria, and rice particles in the species were scattered at the same time, the bacteria have been scattered, is conducive to detection, improve the strains purity. 3, bottled cotton husk or woody species, up and down bacteria strains of bacteria vary greatly, such as mushroom strain up and down 40-60 days. Mycelial germination and inoculation rate were inconsistent after inoculation. The rice shake flasks have the same age, short culture time, and are not easy to age. After inoculation, the mycelium germination is good and uniform. 4, using two inoculation or hole inoculation cultivation method, bacteria bags must be cultivated in a non-sterile environment for 20-60 days, culture materials will usually be added to 10% -20% of corn flour, culture materials, nutrient-rich, easy Infectious bacteria. If rice is first cultivated into a strain, the strain is mixed with a culture material that has been sterilized without corn flour at a rate of 10% to 20%, and then bagged and cultured, and it is not easy to grow bacteria, and the culture time can be greatly shortened. . 5, conventional artificial production of edible mushrooms, such as oyster mushrooms, mushrooms, edible fungus, mushroom, mushrooms, etc. can be directly cooked with fresh water to make bacteria, special edible fungi such as coprinus comatus, lactarius separate artificially prepared iron nutrient solution dip Rice can also produce strains. The use of rice-producing strains to unify the seed production methods of edible fungi is conducive to the development of industrialization and mechanization of edible fungus production.
