在小麦不同基因型的混作群体中,基因型之间存在着不同的竞争效应,而一个竞争能力强的基因型能充分地利用光能及其他自然资源。但是,小麦不同基因型的混作群体能否提高产量,至今尚不明确。本试验的目的就是为了研究小麦基因型间竞争能力的差异和株高不同的基因型混作群体的叶面积垂直分布,并分析混作群体的产量优势,为生产上利用小麦混作群体提供依据。
In mixed populations of different genotypes of wheat, there is a different competitive effect between genotypes and a competing genotype can make full use of light energy and other natural resources. However, it remains unclear whether the mixed population of different wheat genotypes can increase the yield. The purpose of this experiment is to study the differences in the competition ability between wheat genotypes and the vertical distribution of leaf area of different mixed genotypes in different plant height, and to analyze the yield advantage of the mixed population, providing the basis for the production of wheat mixed population.
