以肉桂幼苗为试材,研究了N、P、K不同配比对肉桂容器苗苗高、地径、叶片数以及叶面积、主根长、根尖数、根生物量等指标的影响。结果表明:不同施肥处理均对肉桂容器苗早期生长具有一定的促进作用,施用NP肥对苗高、地径、叶数、叶面积及根生物量等影响较显著,分别是对照的126.0%、128.3%、138.6%、210.2%、147.4%;K肥对根系有较明显的促进作用,主根长、根尖数分别比对照高34.9%、47.4%。
Cinnamon seedlings were used as experimental materials to study the effect of N, P and K on the seedling height, diameter, leaf number, leaf area, main root length, root tip number and root biomass of Cinnamon. The results showed that all the fertilization treatments promoted the growth of Cinnamomum cassia seedlings at early growth stage. The NP fertilizer application had significant effects on seedling height, diameter, leaf number, leaf area and root biomass, which were 126.0% 128.3%, 138.6%, 210.2% and 147.4% respectively. K fertilizers promoted the root system significantly. The main root length and root tip number were 34.9% and 47.4% higher than the control respectively.
