| 摘 要： | 盆栽试验表明：小麦蚕豆间作系统中,常规施肥（NP）水平下,蚕豆茎叶部分生物量在苗期、结荚期和成熟期间作条件下比单作条件下分别增加了11.29%,7.03%,5.90%。在成熟期时,增施钾肥水平条件下间作蚕豆的钾含量显著高于单作蚕豆。间作条件下,蚕豆赤斑病的发生与蚕豆钾含量呈负相关的关系,在结荚期,间作条件下增施钾肥的处理（NPK）与单作条件下增施钾肥的处理（NPK）的赤斑病病情指数相比降低了42.36%。

| Abstract: | Pot experiment were conducted to investigate the potassium uptake and its effect on leaf spots of broad beans in wheat and broad beans intercropping.Results showed that under the normal treatment,the dry weight of broad bean in intercropping increased by 11.29%,7.03%,5.90% compared to that in monocropping during the seedling,the grouting and the harvest stage.In the harvest stage,the K content of broad bean in intercropping was higher than monocropping system.In grouting stage,applying the potassium in intercropping,the disease index reduced by 42.36% compared to that in monocropping.The occurrence of the leaf spots and the K content was a correlation ship. |
