A preliminary report on the effect of different ratio of substrate on the growth of Tetrastigma hemsleyanum
Based on the production practice of the base,this study carried out the application experiments of different ratios of biochar and peat soil,observed the growth of roots,cane leaves and plants of Tetrastigma hemsleyanum,and evaluated the ecological improvement effect of biochar and peat soil,so as to provide technical support for the improvement of the quality of Tetrastigma hemsleyanum.Adding biochar to the substrate in the production of Tetrastigma hemsleyanum can reduce the substrate bulk density,increase the total porosity of the substrate,promote root development,increase substrate pH value,and promote the development of leaves.Moreover,due to the increase in the ratio of bacteria and fungi in the rhizosphere of Tetrastigma hemsleyanum by adding biochar,the substrate micro-environment tends to be bacterial,which is more favorable for its growth.
