摘要
利用三种植物主要营养制剂氯化钾、硫酸锌和硅肥对玉米茎基腐病三种主要病原菌禾生腐霉菌 ( Pythium graminicola)、肿囊腐霉菌 ( Pythium inf latum)、禾谷镰刀菌 ( Fucariumgraminearum )进行了室内生物测定。试验结果表明 ,硫酸锌对腐霉菌有较强的抑制作用 ;氯化钾对三种菌均无抑制作用 ;
The experiment on the effect of selective nutrient agent, such as KCl,ZnSO 4and Si, on the growth of three pathogens of corn stalk rot was carried out in bioassay. The results showed that ZnSO 4 strongly inhibited the growth of Pythium graminicola pathogen, KCl had no inhibition on the growth of the three pathogens of corn stalk rot, Si had significant inhibition on Pythium graminicola and Pythium inflatum.
