| 中文摘要: |
| 以‘中甘15’甘蓝品种和25个不同辣椒品种为试材，采用辣椒-甘蓝间作模式，研究间作对甘蓝根肿病的缓解效果。结果表明，与辣椒间作，甘蓝长势更好，与CK相比，其株高平均增加6 cm，株幅平均增加8 cm，叶球纵径、横径平均增大4 cm；且间作甘蓝的根肿病发病率平均降低约65%，其中甘蓝根肿病缓解效果较好的间作辣椒品种为TL5、TL8、TL12、TL17、TL20、TL21、TL23、TL29，其发病率和病情指数都为0；间作甘蓝平均单球质量1.67 kg，与CK平均单球质量0.71 kg相比，显著提高一倍左右；间作效果综合评价排名前5位的辣椒品种分别是TL18、TL28、TL25、TL29、TL8。因此，辣椒-甘蓝间作模式能明显缓解甘蓝根肿病，促进甘蓝生长，增加产量，与牛角椒TL8、线椒TL18、灯笼椒TL28间作是缓解甘蓝根肿病发生效果较好的品种，可供种植户选择使用。 |
| 英文摘要: |
| This study investigated the effects of intercropping Brassica oleracea cv. 'Zhonggan 15' with 25 different pepper (Capsicum annuum) varieties on the incidence of clubroot in cabbage. The results showed that intercropping with pepper varieties significantly promoted cabbage growth. Compared with the monoculture control (CK), average plant height and canopy width increased by 6 cm and 8 cm, respectively, while both the longitudinal and transverse diameters of the leafy head increased by an average of 4 cm. Intercropping reduced the average incidence of clubroot by approximately 65%. Among the tested pepper varieties, TL5, TL8, TL12, TL17, TL20, TL21, TL23, and TL29 were the most effective in suppressing clubroot, with both incidence and disease index recorded as 0. The average head weight of cabbage in the intercropped plots reached 1.67 kg, more than twice that of the control (0.71 kg). A comprehensive evaluation identified TL18, TL28, TL25, TL29, and TL8 as the top five pepper varieties for intercropping. In conclusion, the pepper–cabbage intercropping system effectively reduces the incidence of clubroot in cabbage, promotes growth, and increases yield. TL8 (horn pepper), TL18 (thread pepper) and TL28 (bell pepper) are especially recommended for disease mitigation and yield improvement in cabbage cultivation. |
