甜菜经济价值的高低取决于产量和含糖率,而准确地测定其含糖率又是育种工作中必不可少的一个环节。无论是确定一个群体的含糖率还是确定一个单株的含糖率,都存在着一个取样代表性的问题。由于甜菜块根的不同部位含糖不同,因此,要准确地测出一株甜菜的含糖率就有个取样部位的问题。本试验进行了对单株取样部位代表性的研究,以确定能够代表整株含糖率的取样部位。
The economic value of sugar beet depends on the yield and sugar content, and the accurate determination of its sugar content is an integral part of breeding work. Whether it is to determine the sugar content of a population or to determine the sugar content of a single plant, there is a sampling representative problem. Because different parts of sugar beet root sugars are different, therefore, to accurately measure the sugar content of a beet have a sampling site problems. This experiment conducted a representative study of the sampling site of the plant to determine the sampling site that can represent the whole plant sugar content.
