A kind of high-yield cultivation technique of Polyporus chinensis

Abstract

The invention provides a new high-yield cultivation technology for polyporus umbellatus. By using a special cultivation medium, spraying an armillaria nutrient solution after polyporus umbellatus is placed and erecting a small shed, a shade net and a micro-spray device, the germination time of polyporus umbellatus is shortened, the germination rate is increased, the annual optimum growth time is prolonged, the dependency of artificial cultivation of polyporus umbellatus on geographical conditions and climatic conditions is effectively reduced, and the cultivation period is shortened, so that the artificial cultivation technology for polyporus umbellatus is more suitable for large-area popularization.

Description

technical field [0001] The invention belongs to the technical field of artificial cultivation of fungi, and in particular relates to a high-efficiency cultivation technology of polyporus. Background technique [0002] Polyporus umbellatus (Pers.) Fr.] is the sclerotium of Polyporus umbellatus (Pers.) Fr., the sclerotium of Polyporus umbellatus, which is a rare and scarce fungal Chinese herbal medicine in my country. effect. Polyporus polyporus has been used as medicine for 2,500 years. Modern studies have shown that polyporus polysaccharides are contained in polyporus polysaccharides, and its compounds have significant therapeutic effects on tumors. Due to its unique curative effect, the demand for Polyporus in the medicine and health care products market has been increasing year by year, resulting in a sharp decrease in the number of wild resources of Polyporus, or even exhaustion. It is imperative to carry out the cultivation of wild Polyporus spp. At present, there are ...

Problems solved by technology

At present, there are many reports on the artificial cultivation of Polyporus. It is known that the growth of Polyporus must be symbiotic with Armillaria armillaria, but there are still at least the following three problems that seriously restrict the large-scale promotion of artificial cultivation of Polyporus and affect the artificial cultivation of Polyporus. Yield:

[0003] First, Polyporus likes a cool, gloomy, moist, loose soil environment. The cultivation substrate of artificially cultivated Polyporus in the prior art has paid close attention to the needs of nutrients such as nitrogen source, moisture, and trace elements of Polyporus. Pay attention to the germination of associated bacteria and the growth of Polyporus chinensis on the coldness, ventilation and drainage of the culture medium. Although the existing culture medium is rich in nutrients, the germination and growth of Polyporus chinensis are not ideal. For example, CN102219612A and CN102812854A emphasize Using humus soil as the culture medium or filler of Polyporus, without realizing that too much humus has high viscosity and poor air permeability in a humid environment, which is not conducive to the germination and growth of Polyporus and its associated bacteria

[0004] Second, in the process of artificially cultivating Polyporus, Armillaria is usually used as the symbiotic bacteria of Polyporus at the same time, but it is not enough to make the honey ring bacteria quickly create a microenvironment that meets the needs of the germination and growth of Polyporus, thus affecting the germination and growth speed of Polyporus

[0005] The 3rd, Polyporus is harsh to growth environment, and the artificial cultivation of Polyporus in the prior art is greatly influenced by topography and natural climate condition, and the area suitable for artificial cultivation of Polyporus is small, meets the best growth condition of Polyporus in a year The time is short, which prolongs the production cycle and affects the economic benefits of artificial cultivation of Polyporus chinensis. For example, CN105248151A, CN103120096A, etc. all need to be cultivated under specific geographical conditions for 4-5 years before they can be harvested to obtain commercially available finished products of Polyporus chinensis.

[0006] Because the above-mentioned factors in the prior art severely limit the popularization and application of Polyporus artificial cultivation technology, there is an urgent need for an efficient, high-yield, artificial Polyporus cultivation technology suitable for large-scale promotion, so as to shorten the cultivation period and realize high-efficiency cultivation of facilities
