摘要
本文对杉木壮苗定向培育试验数据进一步分析,建立了以播种时间、定苗时间、定苗株数对地径影响的数学模型: Y=-9.0560-2.5061lnA-2.8586lnB +4.2272lnC+2.4904lnAB-0.0364（lnA）~2 +0.0490（lnB）~2-0.4343（lnC）~2文中提出应用改进的单纯形法,在变量允许值范围中对培育措施条件进行进一步优化的方法,为试验数据信息有效应用提供了科学方法。
This Paper analysed test data for the oriented cultivation of Chinese fir. Maths model of ground diameter is built as follows, which is about sowing time, final seedling time and final seedling number.
Y = 9.0560-2.50611nA-2.8586lnB + 4.2272lnC + 2.4904lnAB- 0.0364(lnA)2 +
0.0490(lnB)2-0.4343(lnC)2
In this paper,Modified Simplex Method (MSN) is introduced for the optimized condition for the oriented cultivation of Chinese fir.
