小麦品种混播条件下条锈病发生、扩展研究

Six mono-cultivar planting treatments and nine mixed-cultivar planting treatments were designed to study the occurrence and expansion of wheat stripe rust (Puccinia striiformis f.sp.tritici) and control effect of mixed-cultivar planting.The results indicate that the number of foci at seedling stage obviously reduces under mixed-cultivar planting compared with mono-cultivar planting.Over-wintering rate of foci is 77.78% and a few single diseased leaves survive after winter.The spreading distance of stripe ru...
