Production method for morchella importuna cultivars

Abstract

The invention discloses a production method for morchella importuna cultivars. The production method comprises the following steps of: routinely inoculating morchella importuna stock seeds which are cultured at 18 to 20 DEG C for 3 to 5 days to a glass bottle containing a culture material which comprises 70 to 90 percent of wheat, 8 to 28 percent of soil, 1 to 1.5 percent of lime and 0.5 to 1 percent of calcium superphosphate, and culturing the morchella importuna stock seeds at 18 to 23 DEG C for 15 to 20 days under a dark condition to obtain the morchella importuna cultivars. According to the method, the activity of morchella importuna hyphae can be kept, and sclerotia can be quickly produced; and a production process is simple, and conidia are high in yield and easy to seed.

Description

Technical field

[0001] The present invention belongs to the field of biotechnology, and in particular relates to a method for preparing the cultivated species of Morchella edulis. Background technique

[0002] Morchella importuna M. Kuo, O’Donnell & T.J. Volk, Asomycotina, Discomycetes, Pezizales, Morchellaceae, Morchella, Morchella. Mainly distributed in my country's Yunnan, Sichuan, Shaanxi, California, Nevada, Northwest Oregon and British Columbia in Canada. The fruit body is rich in amino acids and vitamins, the meat is crisp and tender, and the flavor is unique. It is one of the treasures in edible and medicinal fungi.

[0003] Cultivation production is the main work in the early stage of edible fungus cultivation. Although the production process and technical requirements are basically the same, different culture material formulas play a key role in the quality of cultivars. At present, the fungus species of the genus Morchella has a long production cycle (the shortest 35 d...
