| 摘 要： | 试验采用分期取样、化验分析、模型拟合的方法对茎芥菜一代杂种JL92-3A×JL155钾积累规律进行了研究,结果表明:茎芥菜各器官钾积累规律符合Logistic方程,钾的旺盛积累期:根为11.9～16.1叶龄,叶为12.1～17.3叶龄,而茎为14.4～17.9叶龄,各器官在旺盛积累期积累的钾达65％以上。根据茎芥菜的钾素积累规律,提出了茎芥菜钾肥的施用建议。

| Abstract: | The pattern of potassium accumulation in stem mustard F_1 hybrid(JL92-3A×JL155)was studied. The result indicated that the potassium accumulation in various organs met Logistic growth curve. Peak period of potassium accumulation in root was at 11.9-16.1 leaf age, in leaf was at 12.1-17.3 leaf age, in stem was at 14.4-17.9 leaf age. During the peak period of potassium accumulation, plant accumulated amount of potassium which accounted for over 65 % of whole growth stage. |
