Keyword:  灰霉病棚菜灰霉病菌盐碱地利用控制发霉辽宁省防治效果稻草覆盖综合防治化学药剂;
Abstract: 灰霉病引起蔬莱果实、叶尖端腐烂生霉,成为限制棚菜产量和效益的主要病害,防治上可综合采取如下几项措施:1防止棚内湿度过大灰霉病菌在空气湿度达到80%以上时能够大量繁殖,防止棚内湿度过大是预防灰霉病的关键措施。要严格控制浇水,阴天和寒流降温之前一般不浇水。缺水时,选晴天上午浇灌不浇大水。要及时排放棚内湿气,特别是阴天更要坚持放风。地膜或稻草覆盖地面、棚下滴灌、电扇吹风、采用无滴棚膜等,都是减少棚内湿度,控制发霉病危害的有效措施。2摘除烂叶和腐果腐烂的果实和叶片是腐生性灰霉菌吸取营养、繁殖的理想场所,应及早发现并彻底摘除枯黄烂叶及腐果,铲除病菌滋生的温床。3调节温度灰霉病菌在16-22C的条件下繁殖
