Qinghai plateau indigenous morchella strain separation technology

Abstract

According to the technical scheme, a Qinghai plateau indigenous morchella strain separation technology comprises the specific separation steps of preparing a culture medium, selecting seed mushrooms,separating mother strains, culturing and purifying hyphae and the like. Wild morchella esculenta in Qinghai is collected, a morchella esculenta variety which is most suitable for Qinghai alpine regions and is high in yield, high in stability and optimal in quality is screened out through many years of separation, purification and cultivation research, an optimal cultivation technology is summarized in combination with local special weather conditions, and yield per mu of cultivated morchella esculenta reaches 150 kg or above. The produced morchella esculenta is strong in mushroom flavor, largein size, thick in texture and richer in nutrition.

Description

[0001] 1. Technical field [0002] The invention relates to a separation technology of morel strains native to the Qinghai plateau, and belongs to a separation method of morel strains. [0003] 2. Background technology [0004] Morel (Morchella deliciosa Fr.) is a rare and valuable edible and medicinal fungus, which is the king of fungi. It has the functions of strengthening the body, preventing and curing diseases, prolonging life and improving human immunity. It is not only a treasure on the banquet, but also a well-known good medicine in medicine. It used to be a nourishing tribute to the royal family. Morchella traditionally mainly relies on collecting wild species. In recent years, the area of ​​artificial cultivation has been expanding, but the cultivation technology is not perfect, especially the strain separation technology, the success rate is less than 10%.

Problems solved by technology

Morchella traditionally mainly relies on collecting wild species. In recent years, the area of ​​artificial cultivation has been expanding, but the cultivation technology is not perfect, especially the strain separation technology, the success rate is less than 10%. Affected by the environment, climate and other conditions, it only grows once a year, and it is difficult to collect, so the output is very small and the price is quite expensive

[0006] The existing Qinghai plateau morel cultivation mainly faces three major problems: one is the strain degradation, which affects the output of morel; Thirdly, the introduced Morchella fungus has a high infection rate, which makes Morchella hyphae lose their growth advantage compared with miscellaneous fungus hyphae and cannot be effectively purified.

This technical shortcoming in the separation of local morel strains in Qinghai has increased the risk and cost of morel planting, making the separation technology of morel strains a major bottleneck in the development of the morel industry in Qinghai
