Table 4:
as can be seen from Table 4: the yield of the dichroa febrifuga is the highest, the average yield of the first three tides reaches 276.19 g/bag, the biological conversion rate reaches 69.05%, and the yield is obviously different from the yields of other strains on the levels of 0.05 and 0.01 except that the difference is not obvious compared with the BJ. The average yield of the first three tides is 245.10 g/bag, the biological conversion rate is 61.28 percent, and the yield is obviously different from that of the large hericium erinaceus at the levels of 0.05 and 0.01. The lowest yield is wild hericium erinaceus, the average yield of the first three tides is only 150.04 g/bag, and the biological conversion rate is only 37.51%.
In summary, the following steps: the results of comparative tests on the growth condition of hyphae on a fungus bag, biological efficiency and the like show that the 10 test strains have obvious difference. Under the same culture medium and culture conditions, the hyphae of different hericium erinaceus strains have different growth vigor and growth speed. On the fungus bag culture medium, the growth speed of hypha of wild hericium erinaceus is the fastest, and the hypha of the wild hericium erinaceus is dichroa febrifuga, and the growth speed of the hypha of the wild hericium erinaceus is 4903. The biological efficiency of 10 hericium erinaceus is also obviously different, the biological efficiency of the dichroa febrifuga is highest, and the average weight of the hericium erinaceus is also highest; the second is the hedgehog hydnum BJ, and the single equal weight is also inferior to the dichroa febrifuga. The biological efficiency of the two strains is obviously different from that of other strains at the level of 0.05 and 0.01, but the difference between the two strains is not obvious. The lowest biological efficiency is wild hericium erinaceus.
The experimental result shows that the dichroa febrifuga has the best single average weight and biological efficiency except that the growth speed of hypha is second to that of the wild hericium erinaceus, has the advantages of pure white color, short thorn, fresh and delicious taste and low pollution rate, and is very suitable for cultivating eucalyptus wood chips serving as the main raw material in Guangxi regions. The subsequent research can be carried out with regional test, and the method is popularized to become a main cultivated variety after further verifying the growth condition, the biological efficiency and the commodity characters.
