近几年来,国内学者对作物群体结构的研究已引起了广泛的注意。在小麦群体结构方面也进行了大量的工作,除对小麦群体发展动态与产量的关系进行研究外,并进而深入到群体光能利用、有机物质的积累与运转等小麦群体生理方面。但据以往报导,对不同密度情况下的群体结构的研究较多,偏重于高产麦田的群体发展规律的研究。小麦群体结构与生产条件密切 In recent years, domestic scholars have paid much attention to the research of crop population structure. Much work has also been done on the structure of the wheat population. In addition to the study on the relationship between the development of wheat population and its yield, it goes further to the physiological aspects of wheat population such as the utilization of light energy and the accumulation and operation of organic matter. However, it has been reported in the past that there are more researches on the population structure under different density conditions, and more emphasis is placed on the research on the law of population development in high-yielding wheat fields. Wheat population structure and production conditions are close
