- 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( Py thium graminicola )、肿囊腐霉菌( P ythium in f latum )、禾谷镰刀菌(Fucarium graminearum )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; 硅肥对禾生腐霉菌和肿囊腐霉菌有明显抑制作用。
- Abstract:
- The ex periment on the ef fect of selective nut rient agent, such as KCl, ZnSO4and Si, on the g row th of three pa thog ens of corn stalk ro t was carried out in bioa ssay. The resul ts showed that ZnSO4 stro ngly inhibited the g row th o f Py thium graminicola pathog en, KCl had no inhibi tio n on the g row th o f the three pa thog ens of co rn stalk rot , Si had sig ni ficant inhibi tio n on P ythium graminicola a nd Py thium inf latum .
