| 摘 要： | 以吉林省西部地区的甘草播种苗为研究对象,对一年生甘草的叶生物量、茎生物量、根生物量、总生物量增长速率及其分配模式,植株的生长速率等进行了研究。结果表明:甘草生物量的动态曲线表现为典型的单峰式,可用五次曲线拟合,生物量的增长速率与植株的生长速率均有明显的季节变化。不同时期甘草各生物组分生物量的分配比例均为根>叶>茎,最终平均单株根、茎、叶的生物量分配比例为48.61%、19.85%、31.54%。地下部分与地上部分生物量之比(R/T)为0.95。

| Abstract: | The research is about Glycyrrhiaz uralensis seedings in the western region of Jinlin Province.Un- ripe G.urahnsis on the annual leaf biomass,stem biomass,root biomass and the total biomass' growth rate,dis- tribution pattern and plant growth rate have been studied.The results showed that:the dynamic curve of biomass of G.uralensis performs a typical single-peak,the curve can be used five times.The equation is,of biomass and plant growth rates have significant seasonal variations.Different periods of each bi... |
