摘要
对四种不同的水分管理条件下香根草生长研究发现:香根草最适宜在土壤水分饱和的湿润环境中生长,这时它的成活率最高,分蘖速度最快,植株高度生长也最快,定植后3个月,其对应的根体积、根干生物量、茎叶干生物量和根茎比也最高。
Vetiver（Vetiveria zizanioides） adapts to a wide ecological range and is very stress-tolerant, and can grow in rather wide range environment. It is a kind of amphibious plant, which can grows well in water and may survive in fairly drought environment. However, water management style has great effects on growth and development of vetiver. The results showed that vetiver grew the best in the soil with saturated water, generated tillers quickliest and produced the most tillers. Meanwhile, 3 months later after transplanting its height, volume of root, dry biomass of the root system, dry shoots biomass and the rate of root-shoot were the greatest of all.
