| 摘 要： | 作物的光强反应特性是确定复合群体中作物搭配以及栽培等措施上合理利用光能资源的基础,本试验研究了在华北地区常见的复合种植体系中玉米和大豆的受光特点和光反应特性以及如何评价一种作物光反应特性和适间套性。当带内株高一致和相近时可以用边行与中行产量比的方法鉴定作物光反应特性,在套作情况下以高秆作物与矮秆作物搭配能更好利用光能,在间作情况下则以高秆作物与矮秆作物搭配为好。鉴定作物的适间套性要考虑发育、光敏感期、种间竞争以及作物的其他特性。

| Abstract: | How to appraise the characteristic of a crop's response to light and the suit- ability to interplanting under the system in which the summer corn or summer soybean be in- terplanted with spring corn.which is popular in Northern China.The result show that if crop's height shows no difference between the belt of spring corn,the rate of crop yield on boundary line to central line can be used to appraise the characteristic of a crop's response to light,otherwise,not.Interplanting higher stalk summer crop betwee... |
