| 摘 要： | 为探明免耕栽培对玉米根系性状及其产量的影响,用杂交玉米贵单8号进行了大田试验,比较了玉米在免耕栽培及常耕栽培条件下的根系性状及其产量表现.结果表明:免耕栽培玉米根系的表面积、根长、体积、根尖数均显著低于翻耕栽培,但根系直径差异不显著；相对于翻耕栽培,免耕栽培玉米穗位叶面积显著减小,穗位高显著降低,但株高和茎粗没有显著差...

| Abstract: | A field experiment was conducted to study root characters and yield of maize under no-tillage cultivation and common cultivation taking the hybrid maize Guidan 8 as the material.The results showed that the root surface area,root length,volumn,number of root tips under no-tillage cultivation were all significantly lower than under common cultivation,but root diameter had no significant difference.Compared with tillage cultivation,ear leaf area and ear height were significantly lower under no-tillage cultivat... |
