摘要
采取田间定点定株调查和定期取样的万法,测定了高产模式田不同生育时期的株高、叶片数、叶面积、鲜重、含糖率、净光合生产率等生态指标.为各时期所应采取的促保高产措施提供了有力的科学理论依据.图6,参2.
In this study,the authors measured many ecological indexes such as plant height,leaf number,leaf area,fresh weight,Sugar concentration.net photosynthesis. Producfivity etc. at different growth stages of sugar beet in high yield model field through the method of investigafing specially designated plants and sampling at specially designated growth stage of sugar beet, It provide scientific basis for taking measures of high yield at every growth stage.
