| 摘 要： | 参考植物病害分级方法，进行春结球甘蓝栽培试验，并且对裂球甘蓝裂口的长、宽、深进行测量，计算裂口弧长与叶球的中部最大周长比、裂口宽与球高比、裂口深与1／2球宽比（0〈x〈t），并作为参数，以这3个参数的和（用∑来表示）将甘蓝裂球的严重程度划分为6个等级标准，0级为∑=0，1级为0〈∑≤20％，3级为20％〈∑≤50％，5级为50％〈∑≤100％，7级为100％〈∑≤180％，9级为∑〉180％。

| Abstract: | Referring to a large number of classification methods of plant diseases,the length,width and depth of cabbage cleft were measured through spring cabbage cultivation experiment.Six standard levels of cracking characteristics in spring cabbage were defined by summing the ratios of the length of cleft to the largest perimeter in the central leaves,the width of cleft to the height of leaves and the depth of cleft to half-width of leaves(0180%). |
