摘要：针对肯氏南洋杉苗期生长缓慢的问题,采用正交试验设计L9（3^4）,通过植物生长所需要的大量营养元素N、P、K 3因素3水平及其不同配比的施肥试验,分析了各元素及其水平对肯氏南洋杉苗高和地径生长的影响,确定了肯氏南洋杉苗期生长的最佳施肥方案。结果表明：18个月不同处理间都呈极显著差异,低水平的营养元素对促进肯氏南洋杉苗高和地径的生长好于高水平,以处理1即N1P1K1为施肥效果最好,且与其它处理呈极显著差异;对肯氏南洋杉苗高生长的影响为N〉P〉K,对肯氏南洋杉地径生长的影响为P〉K〉N。
In order to solve the problem of slowly growing of Araucaria cunninghamii at seedling stage,the trial was designed by orthogonal L9（34）of N,P,K nutrients and three levels respectively in this study.The effects of these nutrients and their levels on growth of seedling height and ground diameter of Araucaria cunninghamii were studied and the best fertilization method was determined.The results show that there were high significant differences among different fertilization treatments through 1～8 months,and the effects of low level N,P, K on seedling height and ground diameter of Araucaria cunninghamii were better than high levels,and the treatment N1P1K1 shows the best fertilization and highest significant among the treatments.The ordination of fertilization effects on growth of seedling height of Araucaria cunninghamii was N〉P〉K and on ground diameter was P〉K〉N.
