摘要
利用甘肃甘谷县和四川盐亭县当地各4个对条锈病具不同抗性的小麦品种,按照抗感品种不同比例混(间)种研究各种植方式对小麦条锈病的防治作用和对小麦的增产效果,并以REM比较各混(间)种种植方式的效果。结果表明,混(间)种对本地菌源引起的病害有明显效果,混种对病害的减轻程度为29.6%-81.9%,对外来菌源引起的病害效果较差;混(间)种对于小麦的增产作用也表现不一,28个混间种处理中,仅8个处理(占28.6%)有增产效果。
Four wheat varieties, with different resistance to the wheat yellow rust in Gangu county of Gansu and Yanting county of Sichuan, were used to study the effects of mixed cropping or intercropping on the wheat yellow rust and the yield. The parameter REM was adopted to analyze the effects. The results showed that multiline cultivars or cultivar mixtures had stronger effects on the disease when the disease was caused by the local pathogen than by the exotic pathogen. They had different effects on the yield.
