Grifola frondosa cultivation method

Abstract

The invention relates to a grifola frondosa cultivation method, which comprises steps of bottling, sterilization, cooling and grafting. The grifola frondosa cultivation method is characterized by also comprising the following steps of: culturing: a culture bottle lid for fixed-point primordium generation is arranged on the opening of a culture bottle in a covering way, mycelium culturing is then performed so that a sporocarp primordium is limited in an expansion space formed on the culture bottle lid, and the culture bottle lid is removed after the sporocarp primordium is formed; mycelium stimulation: mycelium stimulation is performed in a ring shape on the periphery of the primordium of culture materials, and a growth bottle lid made of opaque material is arranged in a covering way; bud inducement: the culture bottle is moved into a bud inducement room for continuous development after mycelium stimulation, and the bud inducement is completed; and growth: the culture bottle is moved into a growth room for continuous development after bud inducement, and the growth is completed; wherein the structure and parameters of a growth bottle lid are set and controlled specially. While the consistency of the appearance of mature grifola frondosa is improved, the leaf differentiation rate of the grifola frondosa in the growth stage can be improved greatly, and thus the quality of the grifola frondosa can be improved.

Description

technical field [0001] The invention relates to a technique for cultivating Grifola frondosa in bottles, more specifically, a method for cultivating Grifola frondosa. Background technique [0002] Grifola frondosa is a kind of edible and medicinal fungus, which belongs to Basidiomycotina, Phylobacteria, Septobasidiomycetes, Non-Pleatellales, Polyporaceae, Arboria fungi. Also known as Bayleaf polypore, chestnut mushroom, cloud mushroom and so on. The fruiting body consists of multiple branched stipe and overlapping spoon-shaped, fan-shaped or tongue-shaped caps, and the caps are 2-7 cm wide; the current domestic cultivars are mainly brown. Bacterial flesh white, 1-3 mm thick; tube pores elongated, orifice polygonal. The spores are colorless, oval to oval. [0003] Grifola frondosa has not been reported to be produced in factories in China at present, but some seasonal cultivations have appeared in Qianxi, Hebei, and Qingyuan, Zhejiang. After the first flush mushrooms are ...

Problems solved by technology

Due to the plastic bag cultivation mode, each bag can only be used once and cannot be reused; secondly, the bagging machine, bag inoculation machine, and handling machine associated with plastic bags are all mechanized because of the softness of plastic bags and other reasons. The difficulty of the cultivation is doubled, and the equipment is expensive, but the efficiency of the equipment is only 1/20 or lower of that of the bottle cultivation. At the same time, the plastic bags are often punctured by sharp objects during daily handling, causing potential pollution hazards.

When the original base of plastic bag cultivation occurs, a large amount of manual "herringbone" cutting process is required at the air-permeable filter membrane to promote the growth of Grifola frondosa from the bag, which causes a lot of labor costs and affects the skills of workers. have a greater dependence

The average output of Grifola frondosa produced by 2.5 kg bag cultivation ranges from 400-700 grams, while the packages that actually enter the market are 100 grams, 150 grams or 200 grams. dismantling and weighing work, which brings inconvenience to the quality management of Grifola frondosa

Generally, a small-diameter hole formed by the primordium of the fruiting body of Grifola frondosa is set in the center of the cover of the cultivation bottle. During the cultivation of mycelia, the primordium of the fruiting body grows in a raised shape from the small-diame
