摘要
应用正交试验对一串红盆栽生产基质进行了研究,对一串红的13个观测指标进行主成分分析,综合为3个主成分。计算主成分综合得分,作为分析指标进行方差分析。结果表明:泥炭∶珍珠岩∶蛭石为2∶2∶2(体积比)为最佳组合。
Medium of pot clutureing of scarlet sage was studied by Orthogonal Design L9(3^4)and Principal component analysis. The results showed that three principal components replace 14 agriculture indexes of scarlet sage in principal component analysis and the optimal combination was A2B3 C3. The most suitable matrix was peat : perlite : lennilite at the ration of 2 : 2 : 2(volume).
