玉米地膜与露地栽培主要性状的灰色关联分析

The Grey Related Analysis of the Main Properties of the Corn Plastic Membrane and Open Air Cultivation

运用灰色系统理论的灰色关联分析方法,分别对西藏林芝地区玉米地膜与露地栽培主要性状与产量之间的关系进行了探讨.分析结果表明,两种种植方式都表现为果穗粒重对产量影响最大.在玉米地膜栽培条件下,果穗重、单株绿叶面积对其产量影响较大,株高、秃顶长对其产量影响较小;在玉米露天栽培条件下,百粒重、果穗重对其产量影响较大,秃顶长、单株绿叶面积对其产量影响较小.

This text uses the grey related analytical method of the grey systematic theory,we has carried on network analysis to the relation between output and main properties of the corn plastic membrane and open air cultivation.We find that the weight of the spike grain affects yield most whichever the planting ways.The spike weight,individual plant greenery area of the plastic membrane planting corn have much more effect on yield,and individual plant height and bald head length affects yield little,while for the open air culture plating corn, hundred grain weight and spike grain weight have much more effect on the yield, and bald head length and individual plant greenery area affects yield small.
