马铃薯由于受蛴螬的危害,严重地降低了产量和品质,造成加工困难,产品滞销。有关薯块受害程度应该如何表示,国内尚为空白。笔者认为,研究制定薯块受蛴螬危害的分级标准,对于客观地反映薯块的受害程度和损失率,统一调查资料的整理分析,以及确定防治指标和开展防治研究,均具有重要的学术价值。为此,作者于1984—1985年对各种受害标本进行了大量的收集整理,分类研究,初步拟定了马铃薯块受害分级标准,结果整理如下。
Due to the harm of potatoes, potatoes seriously reduce the yield and quality, resulting in processing difficulties, the products are unsalable. The extent of potato tuberculosis should be how to say that the country is still blank. The author believes that studying and formulating the grading standards for tuberous tubers affected by tuberculosis is of great academic value for objectively reflecting the extent and rate of damage suffered by tuberous tubers, arranging and analyzing unified survey data, and identifying prevention and control targets and carrying out prevention and control research. To this end, the author in 1984-1985 a variety of victim specimens collected a large number of sorting, classification studies, initially developed potato grading damage classification, the results are summarized below.
