摘要
通过不同栽培密度条件下小麦茎秆形态结构特征的观察,明确了小麦茎秆的生长状况与植株的抗倒性密切相关。基部节间的健壮程度与小麦抗倒伏相关性大小为:第二节间>第一节间>第三节间。茎秆健壮程度因素对茎秆倒伏指数的影响大小为:基部节间壁厚>基部节间长度>节间内径大小,而节间外径大小与植株抗倒关系不密切。
The architectural characteristics of wheat stalks are studied under the different cultural density and the results showed that the lodging resistance quality is closely related to stalk growing conditions.The correlation size of robust degree to resisted lodging:The second length >The first length >The third length?The effect size of robust degree element of stalk to the stalk lodging index number is:The foundation ministry wall thickness>Foundation ministry knot length> inside diameter size,But the relationship of the size of outside diameter size and the combats?
