摘要：根据１１ 年生毛白杨对比试验林的观测数据，对３ 种试验设计的效率作了分析．结果表明，在同一试验地里，当拉丁方数是３ ，随机区组和完全随机化试验的区组与重复数分别是８ 和７ 时，相对效率较高．当拉丁方数小于３ 时，完全随机化试验分析优于随机区组试验分析，又优于拉丁方分析；当拉丁方数大于３ 时则出现相反的趋势．在相似条件下，为了经济、可靠地获得试验结果，以拉丁方数在３ 左右、随机区组试验的区组数不小于５ 及完全随机化试验的处理重复数不小于４ 为宜．
Based on the investigation of the experimental plantations of 11 year old Populus tomentosa Carr.on Wenxian Forest Farm ,Henan Province,the analysis of variance (ANOVA) forthree designs were compared. The results showed that the experimental efficiencies reached the maximum when the numbers of Latin square design (LSD) ,blocks of randomized complete block design (RCBD) and replications ofcompletely random design (CRD) were 3 ,8 and 7 re spectively. When the number of LSD was less than 3 ,the ANOVAfor CRD was more precise than thatof LSDor RCBD,but when the number was morethan 3,the LSDwas more precise. In orderto getexperimentalresultseconomically and confidentlyforforesttree breedingin asimi lar condition,3 Latin square numbers,atleast 5 randomized complete blocks and 4 completely random replicationsarerecom mended .
