Sexual reproduction technique for polyporus umbellatus and cultivation method thereof

Abstract

The invention discloses a polyporus sexual propagation technique and culture method thereof, comprising: 1, spore seedbed culture method: selecting suitable seedbed ground and hacking wood-blocks as fungus substrate, digging pits, scattering the shoestring fungus on wood-blocks and covering soil or rotten plants on the shoestring fungus, selecting good hypha to sow, timely collecting sporophore spores, shredding and broadcasting the sporophore on the fungus substrate, heeling the fungus substrate using rotten plant fine earth tree-leaves, artificial controlling temperature; 2, spore sexual propagation method, (1) wooden case and bamboo basket cultivation method, sawing the fungus substrate into short segments and planting the polyporus in the short segments using the same culture method with the pit culture method, artificial controlling temperature; (2) soiless culture method, culturing the polyporus using soiless pure sand in river using the same culture method with the pit culture method, the inoculation speed of mycelitha and the shoestring fungus is quick and the growth speed is fast; the sexual propagation organs-sporophore of polyporus is directly used, thus 'polyporus flower' is used as strain source, namely the spored on the polyporus flower is used for propagating with strong growing ability and higher yield.

Description

technical field [0001] The invention relates to a sexual reproduction technology of Polyporus chinensis and a culture method thereof. Background technique [0002] Polyporus is a basidiomycete in fungi of the genus Polyporus, belonging to Polyporaceae, Polyporaceae, Polyporus genus. It is the dried sclerotium of the fungus Polyporus; it has the functions of diuretic and dampness, immune function, and liver protection. It is a cherished variety of Chinese medicinal materials. , the market demand is large, and the supply gap is also large. At present, most of the cultivation techniques of Polyporus chinensis in China adopt asexual propagation method, namely sclerotia propagation method - Polyporus chinensis "mother nucleus" grows "daughter nucleus", and "child nucleus" grows "grandson nucleus" and is reborn from generation to generation; Asexual reproduction has been inherited for several generations, resulting in the degeneration of the Polyporus sclerotium, the reduction of...

Problems solved by technology

At present, most of the domestic cultivation techniques of Polyporus chinensis adopt the method of asexual reproduction, that is, the sclerotia method - the "mother nucleus" of Polyporus umbilicalus grows "daughter nucleus", and the "daughter nucleus" grows "grandchild nucleus" to reproduce successively from generation to generation; After several generations of asexual reproduction, the species of Polyporus umbilicalis degenerates, the reproduction coefficient decreases, the sclerotia becomes smaller, the germination decreases, the cultivation period is long, the yield decreases, and the commercial value rate is low; although there are also tissue separation of Polyporus sclerotia , made into first-, second-, and third-level species for breeding and production, but it is still in the experimental demonstration stage
