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.
The gray relational analysis method of gray system theory was used to discuss the relationship between the main characters and yield of maize mulch and open field cultivation in Linzhi area of Tibet.The results showed that the grain weight of the two kinds of planting methods all showed the greatest impact on grain yield Under the conditions of maize mulching cultivation, the ears were heavier and the leaf area per plant had a greater influence on the yield, while the plant height and baldness had less effect on the yield. Under the open-field cultivation of corn, A greater impact, long bald, green leaf area per plant little impact on their production.
