Breeding method and cultivation method for industrialized bottle cultivated oyster mushroom variety

Abstract

The invention discloses a breeding method for an industrialized bottle cultivated oyster mushroom variety. The breeding method comprises the following steps: by taking a high-yield strain P99 and a wild strain NY-2 as parent strains, creating a batch of new oyster mushroom varieties through a mono-spore hybridization technology; circularly planting by adopting an industrialized bottle cultivated mushroom producing manner; and screening a good strain suitable for industrialized production: P14Y6, wherein the strain is black, has no stems, a thick mushroom cap and good toughness and can be transported for a long distance. The mushroom producing temperature is 12 DEG C-15 DEG C, the mushroom producing uniformity is 95% or more, the average yield of a single bottle is 180g, the weight of culture materials of the single bottle is 250g and the maximum weight is 20 grams per bottle; the biological efficiency of one flush of the mushroom is 70% or more and the production period is 40 days; and no diseases and insect pests occur within a production period and year-round supply can be realized, so that the blank of special varieties of industrialized oyster mushrooms in China is made up.

Description

technical field [0001] The invention relates to the cultivation of Pleurotus ostreatus, in particular to a method for breeding varieties of Pleurotus ostreatus planted in industrial bottles, and also relates to an industrial cultivation method of the type of Pleurotus ostreatus. Background technique [0002] Pleurotus ostreatus has become a must-have dish on the public table because of its rich nutrition and moderate price. In 2015, the total output of Pleurotus ostreatus in China reached 5.9018 million tons, which is the third largest type of edible fungus that can be cultivated artificially. Henan Province is a major province of oyster mushroom production, and its total output accounts for 30% of the total amount of oyster mushrooms in the country. The most suitable temperature for fruiting of Pleurotus ostreatus is 12~18°C. Due to the influence of the environment and climate, the production of Pleurotus ostreatus in Henan Province is mostly concentrated in autumn, winter...

AI Technical Summary

Problems solved by technology

Since traditional Pleurotus ostreatus varieties require 3 to 4 crops of mushrooms in production, and industrial production requires one crop of mushrooms, the biological efficiency can reach more than 70%. Low yield, low yield and biological efficiency of a crop of mushrooms, intolerance to carbon dioxide, etc., cannot adapt to the existing bottle planting production mode, and there is an urgent need to cultivate new varieties of oyster mushrooms suitable for factory bottle planting
