Effects of Cordyceps chanhua spent mushroom substrate on the growth of commom bean seedling
In order to investigate the effect of Cordyceps chanhua spent mushroom substrate on the growth of commom bean seedlings,a pot experiment was conducted in this study.The experimental group(sterile soil+C.chanhua spent mushroom)and the control group(sterile soil)were set up to determine the agronomic traits index,root index and chloro-phyll content of bean seedlings.The results showed that the C.chanhua spent mushroom increased the total root length,root volume and chlorophyll content of the commom bean seedlings,but decreased the total tip number,branch number and crossing number.At 15 d,the maximum leaf length and leaf width of bean were significantly increased by the applica-tion of C.chanhua spent mushroom.At 30 d,the plant height was significantly increased by adding C.chanhua spent mushroom.At 15 d,compared with the control group,the plant height,leaf number and stem diameter of the experimental group were increased by 36.36％,25.00％and 30.97％,respectively.At 30 d,the plant height of the experimental group was significantly increased by 40.83％compared with the control group,and the stem diameter,leaf number,maximum leaf length and maximum leaf width were increased compared with the control group.In addition,compared with the con-trol group,the fresh mass of the aboveground part,the fresh mass of the underground part,the dry mass of the aboveg-round part,the dry mass of the underground part and the root shoot of the experimental group were all increased.There-fore,adding the C.chanhua spent mushroom into seedling soil can effectively promote the growth of commom bean at seedling stage.
