A new strain of Poria cocos and its high-efficiency cultivation technique

Abstract

The invention discloses a novel tuckahoe strain (china center for type culture collection (CCTCC) M2011072) and bag-material efficient cultivation technology. The novel tuckahoe stain is applied to cultivation by adopting the bag-material efficient cultivation technology. The novel tuckahoe stain is mainly characterized in that 1) a mycelium is strong, white, obvious in clamp connection; and hypha is spread quickly in a cultivation process; 2) the tuckahoe fruits earlier, the fruit body is even and strong, the color of pulp is white or light yellow, and the skin of tuckahoe is thin and presents purplish red color; 3)the novel tuckahoe strain has the advantages of being stable inheritable characteristics, strong in anti-bacteria infection capacity, high in biological efficiency and yield, good in quality and the like; and 4) the novel tuckahoe strain remarkably improves content of effective components of amino acid, pachymaran and the like in the tuckahoe.

Description

technical field [0001] The invention relates to strain selection and cultivation technology thereof, in particular to new strain selection and high-efficiency cultivation technology of poria cocos. Background technique [0002] Poria Cocos (schw) WOLF) is a polypore fungus (Basidiomycete), sweet, light, and flat in nature. , is also one of the prescriptions of "Four Gentlemen and Eight Treasures", and its market prospect is very broad. [0003] The main component of Poria cocos is β-pachyan (also known as "Poria cocos polysaccharide"), which accounts for about 93% of the dry weight. Poria polysaccharide is an immune enhancer, which has the functions of enhancing immunity, adjuvant chemotherapy, preventing and treating tumors, and anti-tumor. It has been widely used as a new anti-cancer drug, hepatitis rehabilitation drug, and used to treat bronchial asthma and chronic bronchitis. Existing Poria health products include Poria flat tablets, Poria rolls, Poria cubes, Poria pol...

AI Technical Summary

Problems solved by technology

[0005] However, domestic and foreign studies on the breeding of new strains of Poria cocos and their high-efficiency cultivation techniques are still insufficient.

The artificial cultivation technology of Poria cocos began in the 1960s, and the Poria cocos strain "5.78" was used for meat cultivation, and the section wood, round wood or tree stump after felling pine trees were mainly used as the cultivation substrate (also known as "fungus material"). The method exists that the cultivation technology is backward, and a large amount of pine resources need to be consumed, and the strains have been propagated for many years, and the vitality of the strains has declined, and the Ling body has become smaller, and natural variation occurs, and the variety is aging and degraded, and the biological efficiency is significantly reduced (from 30 %-40% down to 10%-20%), and there are defects such as inoculation survival rate, formation rate, Poria cocos yield, Poria cocos quality, resource utilization rate are all on the low side, production cost is too high, industrial benefit is not ideal
