Method for improving yield of high-quality lentinus edodes by grafting of mushroom bricks and mushroom sticks

Abstract

The invention discloses a method for improving yield of high-quality Lentinus edodes by grafting mushroom bricks and mushroom sticks, which comprises the following steps of: (1) preparing the mushroomsticks, wherein main materials of the mushroom sticks are wood chips and wheat bran, and a ratio of the wood chips to the wheat bran is 8:2; and preparing lentinus edodes mushroom sticks by a conventional method and carrying out normal cultivation; (2) preparing the mushroom bricks, wherein the main materials of the mushroom bricks are the wood chips and the wheat bran, and the ratio of the woodchips to the wheat bran is 55-65:35-45; preparing Lentinus edodes mushroom bricks by the conventional method; preparing a cylindrical pit for grafting the mushroom sticks prepared by (1) above the mushroom bricks, wherein time of preparing the mushroom bricks is later than 30-35 days of the mushroom sticks prepared by (1); and (3) grafting: when the mushroom sticks change color and begin to produce mushrooms, and when the mushroom bricks just fill up, carrying out the grafting, removing plastic firm at one end of the mushroom sticks and the cylindrical pit of the mushroom bricks, inserting themushroom sticks into the pit of the mushroom bricks vertically; and after 3-5 days mycelium of the mushroom sticks and mushroom bricks are connected together, and nutrition and moisture of the mushroom bricks are transmitted to the mushroom sticks through a mycelial network. By the adoption of the method for improving the yield of the high-quality Lentinus edodes by grafting the mushroom bricks and the mushroom sticks, the yield of the high-quality Lentinus edodes is increased by more than 30%.

Description

Technical field [0001] The invention belongs to the technical field of edible mushroom cultivation, and particularly relates to a method for improving the yield of high-quality mushrooms by grafting mushroom bricks and mushroom sticks. Background technique [0002] Shiitake mushroom is one of the most cultivated edible mushroom varieties in my country. At present, the cultivation method of mushrooms in my country generally uses 80% wood chips and 20% wheat bran as the main raw materials, and uses plastic bags to make fungus sticks or molds to make fungus bricks for cultivation and production, which has not been available for decades. Big change. In the raw materials, sawdust is responsible for providing carbon source, and wheat bran provides nitrogen source, both of which maintain the carbon to nitrogen ratio required for the growth of mushrooms. At present, the problem is that in the traditional formula, the nitrogen source provider wheat bran has a soft structure, and the nutr...

AI Technical Summary

Problems solved by technology

At present, the problem is that in the traditional formula, wheat bran, the nitrogen source provider, has a soft structure, and the nutrient decomposition and release speed are fast, while the carbon source provider, wood chips, has large particles and is relatively hard, and the nutrient decomposition and release speed is slow.

However, after the third harvest, due to the fact that there is still a lot of carbon source in the fungus bag, and the nitrogen source is released more in the early stage and less in the later stage, the carbon-nitrogen ratio increases rapidly, which can no longer meet the normal development needs of mushroom fruiting bodies, resulting in The quality of the mushrooms has declined rapidly, manifested in the phenomenon that the bacteria become smaller, thinner, and easy to open umbrellas. A large number of defective shiitake mushrooms have seriously affected the economic benefits of shiitake mushroom cultivation.
