摘要
以速生小白菜品种"快菜30"为试材,对小白菜的株高、叶片数、最大叶长、最大叶宽、单株地上部干鲜重、单株地下部干鲜重等指标进行观测,并对结果进行Logistic生长曲线方程拟合。结果表明:小白菜的生长发育与定植时间之间可以用Logistic曲线方程表示,并且达到了显著水平。各个指标生长都呈现单S曲线,各个曲线的拐点出现时间是其生长的关键时期。
The dynamics changes of Chinese cabbage were studied in order to research the growth rhythm.The main agronomic characters（petiole length,leaf number,leaf length,leaf width,fresh weight and dry weight of ground part and underground part）of Chinese cabbage were conducted.The results showed that Logistic growth curve could be used to express the relationship between growth and planting time which reached significant levels.The growth curve were all single S type and it was very important time when reached the inflexion time.
