摘　　要：针对草坪草苗期腐霉枯萎病菌(Pythium spp.)可由土壤和种子携带的特点,以恶霉灵、甲霜灵杀菌剂和植物生长调节剂等为原料研究草坪种衣剂,并在黑龙江省进行了药效试验。研究结果表明,筛选出的药物型和药肥复合型草坪专用种衣剂对草坪草安全无害,不仅对草坪草苗期腐霉枯萎病防效在80%～97%,而且能促进草坪草生长,与对照相比,2号和5号种衣剂处理的植株增高了1.63～2.73 cm,根长增加1.5～2.5 cm,根质量增加了1.54～1.81 g,分蘖数增加了1.33～2.00个。Based on Pythium diseases caused by the soil borne and seed borne pathogens,an experiment was conducted to develop a seed coating formulations to control Pythium diseases in Poa pratensis at the seedling stage of turf grasses by combing hymexazol,metalaxy and plant growth regulator in Heilongjiang province.This study indicated that the seed coating formulations of drug type and special fertilizer compound type specialized for turf was safe and harmless to the turf grass.These two seed coating formulations not only reduced the incidence of Pythium diseases by 80%～97%,but also encouraged the turf grass growth.Seed coating of hymexazol＋thiram and hymexazol＋thiram＋root stimulate increased plant height with 1.63～2.73 cm,root length with 1.5～2.5 cm,root weight with 1.54～1.81 g,tiller with 1.33～2.00 number.
