Problems solved by technology

TNN-12 has the advantages of good fruiting body shape, uniform mushroom cap size, uniform pattern, mushroom shape suitable for box packing and not bitter, but its long cultivation cycle affects the efficiency and cost of factory production. With the intensification of competition, the problems of long cultivation period and long cultivation period are becoming more and more prominent
In addition to the large-scale planting of the TNN-12 strain in Japan, there are also some small-scale planting strains, each of which has its own advantages and disadvantages. For example, the F-FG strain has the advantage of short cultivation period, but its mushroom cap is flat and Unsatisfactory type

Embodiment 1

[0028] Embodiment 1 A kind of method of cultivating the mushroom strain WZ-29

[0029] The present embodiment discloses a method for cultivating jitake mushroom strain WZ-29, the method comprising the following steps:

[0030] (1) Bacteria culture

[0031] Inoculate the mushroom strain WZ-29 in the culture medium for cultivation, and the cultivation conditions are as follows: the temperature is 20-25°C; the relative air humidity is 70-80%; CO 2 The concentration is 2000-3000ppm, cultivated for 30-38 days to obtain mycelia;

[0032] (2) Cultivation of mycelium

[0033] The mycelia obtained in the step (1) is inoculated in the fruit body medium for cultivation, and the cultivation conditions are: the temperature of the cultivation room is 20-28°C; the relative air humidity is 70-80%; CO 2 The concentration is 2500-4000ppm, cultivated for 70-78 days to obtain cultivated mycelium;

[0034] (3) Cultivate and produce fruiting bodies

[0035] The cultivated mycelium obtained in ...

Embodiment 2

[0040] Embodiment 2 A kind of true mushroom

[0041] Comprehensively considering aspects such as strain yield, stability and uniformity, the jiji mushroom produced according to the cultivation method of Example 1 is screened to obtain an optimal strain, which is named jiji mushroom strain WZ-29 . The mushroom strain WZ-29 has been preserved in the Guangdong Provincial Microbial Culture Collection Center on November 8, 2017. Its preservation number is GDMCCNO: 60276, and its biological classification is named Hypsizygus marmoreus WZ-29. The jitake mushroom produced by the jitake mushroom strain has the following characteristics:

[0042] The color of the spots in the center of the mushroom cap is light brown, and the color gradually fades towards the edge. The spots are evenly distributed in the center and regularly distributed, such as figure 1 As shown: the flesh is thick and crisp, without cracks; the hyphae are dense and the aerial hyphae are well developed; the gills are...

Embodiment 3

[0045] In this embodiment, the comparison between the jitake mushroom strain WZ-29 in the present invention and the jijitake mushroom strain Finc-W-227 in the prior art is carried out. These two bacterial strains are all cultivated according to the culture condition in embodiment 1, and experimental result is as follows:

[0046] Table 1

[0047]

[0048]Taking Finc-W-227 as the control, set 6 bacterial ages from 70d (that is, days, the same below) to 95d, each increment of 5d is a bacterial age, and each bacterial age is 80 bottles. The volume of the cultivation bottle is 850cc, and the diameter of the bottle mouth is 58mm.

[0049] The results of this experiment are shown in Table 1. The highest yield per bottle of Finc-W-227 is 228g / bottle, and the optimum bacterial age is 90d. The highest yield per unit of WZ-29 is 250g / bottle (that is, gram / bottle, the same below), and the optimal bacterial age is 90d. Through comparison, it can be seen that WZ-29 has obvious advant...

Abstract

The invention relates to the technical field of edible fungi, and in particular relates to a hypsizygus marmoreus strain and a culture method thereof. The hypsizygus marmoreus strain WZ-29 has a preservation number of GDMCC NO: 60276. Hypsizygus marmoreus grown from the hypsizygus marmoreus strain WZ-29 disclosed in the invention has extremely high homogeneity and excellent morphological characteristics, so that packaging and sale of the product and establishment of an edible fungus brand are facilitated. In addition, the strain has a short culture and cultivation period and stable biologicalcharacteristics, and greatly improves the production efficiency and stability of a plant; and yield per unit is high, every bottle is basically consistent when mass production is performed, and the strain has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of edible fungi, in particular to a strain of jijiji mushroom and a cultivation method thereof. Background technique [0002] Hypsizygus marmoreus (Latin Hypsizygus marmoreus) belongs to Basidiomycotina, Phyllomycetes, Agaricaceae, Agaricaceae, Liphyllum family, and Amygium genus. Because it has a unique crab flavor, it is also called crab-flavored mushroom. At present, there are mainly two types of Shiji mushrooms produced in factories: brown and pure white. Pure white Shiji mushrooms are also called white jade mushrooms or jade dragon mushrooms. [0003] True jiji mushrooms are rich in vitamins and 17 kinds of amino acids, among which the content of lysine and arginine is higher than that of common mushrooms, which can help teenagers improve intelligence, fight cancer and lower cholesterol. In particular, the extract of the fruiting body (the part above the culture medium) has various physiologically act...
