Technical Field

The invention relates to the technical field of edible mushroom planting, in particular to a planting method of lepista nuda.

Background

With the rapid development of the liquor industry in Renhuai city, 30 ten thousand mu of organic sorghum is planted in the whole city, and the annual yield of sorghum straws reaches 15 ten thousand tons. The growing up of the cattle raising industry in rural areas causes the cattle manure to rapidly increase in quantity and continuously accumulate, which brings serious harm to the ecological environment and the life of common people. The lilac mushroom is a wild rare medicinal edible mushroom used as medicine and food in Agaricales, Tricholomataceae and Tricholoma, is named together with matsutake and bolete, is delicious and fragrant, contains rich active substances such as vitamins, proteins, polysaccharides and the like, can enhance the immunity of the organism, has multiple effects of resisting cancer, resisting inflammation, inhibiting bacteria, resisting oxidation and the like after being eaten frequently, and has a good cultivation effect on a grass manure decomposed culture medium. The lepista nuda has high research and development values as rare edible and medicinal fungi, but the lepista nuda is mainly collected in the field so far, the natural resources are limited, the quality cannot be guaranteed, and although the lepista nuda strains are artificially cultured at present, the conventional culture method has long fruiting time and low yield and cannot be industrially popularized.
