近几年来,国内很多科研单位对农作物在一定产量水平下的技术指标及主要阶段的形态生理指标进行了研究。有些单位的研究已为生产提供了可靠依据;有些单位正集中进行研究。其目的在于通过这些指标可以主动指导农业生产,灵活运用农业技术的促控措施,对生产有预见性,以使逐步实现作物高产“长相”指标化,测定代表性,田间管理科学化,使栽培技术更好地为实现农业现代化服务。
In recent years, many domestic research institutes have studied the technical indexes and the morphological and physiological indexes of crops under certain output levels. Some units of research have provided a reliable basis for production; some units are focused on research. Its purpose is to guide agricultural production through these indicators, make flexible use of agricultural technology to promote control measures, and have predictability on production in order to gradually achieve the indexization of high-yielding crops, determine the representativeness, scientifically manage the fields, Technology to better serve the modernization of agriculture.
