Method for controlling formation of invalid primordia of factory-like bag-cultivated oyster mushroom

Abstract

The invention discloses a method for controlling the formation of invalid primordia of factory-like bag-cultivated oyster mushrooms, and belongs to the technical field of oyster mushroom cultivation. The invention discloses a method for controlling the formation of the invalid primordia of factory-like bag-cultivated oyster mushrooms. The method comprises the steps of sterilization, cooling, inoculation and spawn running culture, lantern ring removal and fruiting. According to the method, the primordia can be only formed in lantern ring areas by strictly controlling the gaps between culture bags and culture materials and the gaps between bag shoulders of the fungus bags and the surfaces of the culture materials, so that the formation of invalid primordia of the bag-cultivated oyster mushrooms in the bags is avoided, the labor cost is not increased, and the method is very simple and easy to implement. By reducing the formation of the invalid primordia, the nutrient consumption can be reduced, the high commodity quality of oyster mushroom sporocarps is ensured, and the economic benefit is improved. The method is easy to master and popularize and suitable for factory-like bag-cultivated oyster mushroom production.

Description

technical field [0001] The invention relates to the technical field of Pleurotus ostreatus cultivation, and more specifically relates to a method for controlling the formation of invalid primordia of Pleurotus ostreatus planted in factory bags. Background technique [0002] my country is a major producer of edible fungi in the world, and the output of edible fungi accounts for more than 70% of the world's total output. According to statistics from the China Edible Fungi Association, the total output of edible fungi in the country in 2019 was 39.3387 million tons (fresh products), with an output value of 312.667 billion yuan. Pleurotus ostreatus is the third largest edible fungus species in my country. The national output in 2019 was 6.8647 million tons. Henan Province is a major province of Pleurotus ostreatus in my country. The output in 2019 was 1.1526 million tons, second only to Shandong (1.1578 million tons). It ranks second only to the output of shiitake mushrooms in Ch...

Problems solved by technology

For example, in the case of cutting bag fruiting or punching fruiting, due to the existence of gaps, many primordiums are often formed in the gaps, resulting in fewer primordia at the mouth of the bag and punching mushrooms, or after the ring cover is removed, It was planned to produce mushrooms at the ring seal, but due to the existence of gaps, many primordia appeared on the bag body or at the contact part between the lower part of the ring and the bag. Rare primordia are formed, resulting in fewer final primordia, extremely low yields, and poor commodity properties
