Abstract:

In order to know the dissimilar result of using several straw and stalk substrates to plant oyster mushroom and to convenient for adjusting measures to local conditions in yielding mushroom, so the tests were set up especially. Twelve kinds of straw and stalk substrates were put up to plant oyster mushroom, observe and memorize in every period. Results showed that the growth speed, the way corp was growing, the yield for the first time of the oyster mushroom’s mycelial present remarkable difference. According as the ingredients of the different substrates, there were several aspect characteristics in the tests: First, when the range of C/N was from 20 to 50, and that the ratio between the disolubility glucide and the gross fibrin in the substrate was near the 1, the mycelial’s growth was the best, the yield for the first time was the highest; Second, when the range of C/N was from 20 to 50, but the ratio between the disolubility glucide and the gross fibrin in the substrate was higher than 1.5, the way corp was growing of the mycelial was worse, the mushroom in small was easy to die; Third, when the ratio between the disolubility glucide and the gross fibrin in the substrate was near the 1, but the range of C/N was more higher than 50, the growth of the mycelial was slow, the way corp was growing was worse, the yield for the first time was lower. Because the ingredients of straw bale work on the growth of oyster mushroom, the straw and stalk substrate must be adjusted before using it to plant oyster mushroom.
