摘要
利用生物因子镰刀菌菌株F1和F5,针对玉米青枯病主要致病菌禾生腐霉菌 (Pythiumgraminicola)和禾谷镰刀菌 (Fusarium graminearum )进行诱导玉米抗青枯病技术研究。研究结果表明 ,注射诱导接种法和土壤诱导接种法均能获得良好的免疫效果 ;以播前土壤诱导接种法为最佳 ,效果好 ,持效期长。当迟滞期为 16d时 ,挑战后 6 3d诱导效果仍为 10 0 %。土壤诱导接种法最佳迟滞期是 16d ,注射诱导接种法的最佳迟滞期是 10d。
Using biological factor fusarium strains F 1 and F 5, the induced techniques of resistance to corn stalk rot were studied respectively directed at the major pathogens Pythium graminicola and Fusarium graminearum. The result showed that two induced methods of injection and soil inoculation could get good immunity results. The effect of soil inoculation before sowing was the best and its protection period could be kept longer. When the lag period was 16 days, the induced effect after 63 days challenge inoculation remained 100%. The best lag period of soil inducing inoculation was 16 days, for injection inoculation it was 10 days.
