近年来,南繁甜菜种子发运到北方各站,经抽测在数量和质量上都与产地检测结果存在很大差异。特别是近年来,发运到北方的种子含杂高、减量大。为了弄清其产生的原因,减少损失,提高经济效益,我们于1992年进行了试验探讨,结果简报如下。材料与方法 In recent years, the South beet seeds shipped to the north of the station, the test by both the quantity and quality of the test results with the origin there is a big difference. In recent years, in particular, the seeds shipped to the north contain large and large losses. In order to clarify its causes, reduce losses and improve economic efficiency, we conducted a pilot study in 1992, the results briefed as follows. Materials and Methods
