不同生态区收获期甜菜库源关系及含糖率的调查研究

Investigation on the Relationship Between Source-sink and Sugar Content of Sugar Beet in Different Ecological Areas During Harvest

过去诸多研究主要是在小区试验精确控制条件下进行的收获期R/T比值与产量关系及含糖率的研究.本文试图通过田间大区调查研究的方法摸清收获期甜菜库源关系,不同生态区库源关系特点及含糖分布,为甜菜生产提供依据.

In the past,many studies mainly focused on the relationship between R/T ratio and yield at harvest stage as well as sugar content under the precise control of plot experiments.This paper attempts to find out the source-sink relationship of sugar beet in harvest period,the characteristics of source-sink relationship and the distribution of sugar content in dfferent ecological areas by means of field investigation and research,so as to provide a basis for sugar beet production.
