摘要
基于基地生产实践,开展生物质炭、泥炭土等不同配比基质应用试验,观察三叶青块根、藤茎叶及植株长势,对生物质炭、泥炭土等基质生态改良效果开展评价,为三叶青品质提升提供技术支撑.试验发现,三叶青生产中,基质加入生物质炭能起到降低基质容重、增加基质总孔隙度、促进根系发育、提高基质 pH 值、促进三叶青叶片发育等作用.生物质炭的加入提高了三叶青根际细菌/真菌比值,使基质微生态环境偏向细菌型,对三叶青生长更为有利.
Abstract
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.
