Abstract:
The towel gourd of ‘Lyuzuan 88’ was used as test materials，maturity of peanut，corn and rice straw and perlite，vermiculite were mixed according to a certain proportion of compound substrate on towel gourd seedlings morphological indexes and photosynthetic pigment contents，photosynthetic characteristics，root activity，enzyme activity and other physiological indicators of the impact，in order to towel gourd seedling to explore the compound medium straw instead of peat and other conventional seedling substrate.The results showed that the different straw compound matrix in general increased towel gourd seedlings height and stem diameter，root length and leaf area and improve the towel gourd seedling index，and the index of corn straw mixed matrix under Y treatment，increased 32.60%，5.86%，7.92%，14.64% and 10% respectively.Compared with the control，corn straw compound substrate significantly increased (P<0.01)，and increased the chlorophyll content and photosynthetic rate of towel gourd seedlings.The combination of rice and peanut straw was better than that of control，but the difference was not significant (P<0.05).Root activity，SOD activity，soluble sugar content and soluble protein content were the best treated with corn straw compound substrate Y，followed by rice straw compound matrix，and root activity and soluble protein content were higher than those of peanut straw composite substrate.Considering the maturity of corn straw can replace peat and perlite，vermiculite was used as towel gourd seedling substrate.
