摘要
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%。
Taking the seedling of Cinnamomum cassia Presl as material, the effect of different fertilizer treatments on seedling height,diameter, leaf number, leaf area, primary root length, root number and root biomass were studied. The results showed that the growth of seedling of Cinnamomum cassia Presl under different fertilizer treatments increased, seedling height, diameter, leaf number, leaf area and root biornass were the best under NP fertilizer treatment, were 126.0%, 128. 3 %, 138. 6% , 210. 2 %, 147. 4% compared with the control respectively; there were the longest primary root length and the most tip of root under NP fertilizer treatment,were 34. 9% ,47. 4% higher than control respectively.
