摘  要:
通过大田试验研究了氮磷钾肥对南板蓝穿孔病危害程度的影响及该病的防治措施。结果表明,在南板蓝的栽培周期内,南板蓝穿孔病在7月15日前后的危害最严重。在尿素、碳铵、硝铵3种肥料中,使用尿素时南板蓝穿孔病的发生率最低,危害程度最轻。氮、钾肥的施用量及氮、磷肥的合理配施对南板蓝穿孔病的防治具有显著作用。

摘  要:
The effects of nitrogen,phosphor and kalium on the hazard index of holing illness and the prophylactic-therapeutic measures has been studied while the field experiment had been applied.The results indicated that,in strobilanthes cusia's whole life,the holing illness did it's best harm around july 15.Among all nitrogenous fertilizer(the carbamide,ammonium bicarbonate and ammonium nitrate),the carbamide played an activest role.The quantity of nitrogen fertilizer and potash fertilizer and the proportion of nitrogenousphosphatic fertilizer were very important to the prevention and cure.
