烟叶出片率的预测及其与其他物理特性的关系
为研究烤烟叶片物理特性与出片率的关系,建立烤烟出片率的预测模型,应用逐步回归分析、偏相关分析和通径分析等方法对35个烟叶样品进行了分析。结果表明:叶长(X1)、厚度(X3)、抗张力(X6)、平衡含水率(X8)和含梗率(X9)是影响烟叶出片率(Y^)的主要物理指标,叶长、抗张力、平衡含水率与烟叶出片率呈显著正相关,厚度、含梗率与烟叶出片率呈显著负相关;叶长是影响叶片出片率的最主要决策因素;厚度是影响烤烟叶片出片率的最主要限制因素;5个因子以及它们之间的相互影响决定了烟叶出片率的99.97%,并建立了烟叶出片率的预测模型:Y^=51.173 8+0.679 9X1-0.569 2X3+8.009...
