摘要
该研究采用普查法和"W"9点取样法对绍兴市区草坪绿地杂草发生危害进行调查,并采用国光卓尔、秀百净、金百秀、刹它隆、国光均合迪、坪阔净、国光壹变静和阔莎一次净8种除草剂对绍兴市马尼拉草坪上常见草坪杂草等进行药效试验。结果表明,绍兴市区草坪绿地杂草发生危害较为普遍。调查记录到草坪绿地害草种类71种,草害频率在60%以上的主要杂草种类有9种,分别为马唐、狗尾草、喜旱莲子草、铁苋菜、钻叶紫菀、小飞蓬、黄鹌菜、酢浆草、水蜈蚣等。对于夏季马尼拉草坪的禾本科杂草危害,可采用金百秀防治,除草效果可达90%以上。阔莎一次净对于阔叶杂草的防除比较彻底,除草效果达到90%以上,而对莎草的防除效果较差,可选择使用。刹它隆、坪阔净、国光壹变静等对阔叶杂草防除效果达100%,但对马尼拉草坪草有危害,可以选择在草坪建植前使用。总之,草坪草害群落中发生的杂草种类不同,在选择除草剂品种时也应有针对性,以提高除草效果。
The weed in turf was investigated by using general investigation and inverted W-pattern with 9 samplingpoints in Shaoxing City.And 8 kinds of herbicide were used to test the efficacy of weeds in the lawn of Zoysia turf inShaoxing.The results indicated that the weed did great harm to the turf in Shaoxing.71 species of weeds were identi-fied.There were 9 major kind of weed that the rate of calamity was over 60%,they were Digitaria sanguinalis,Setaria viridis,Alternanthera philoxeroides,Acalypha australis,Symphyotrichum subulatum,Erigeron Canadensis,Youngia japonica,Oxalis corniculata,Kyllinga polyphylla et al.Using Jinbaixiu can control the harm of Zoysia turf grasses insummer.It can control at least 90%of the grass weeds.Pingkuoyicijing can control at least 90% of the broad leavedweed,while the sedge control effect is poor.Shatalong,Pingkuojing,Guoguangyibianjing can control at least 100% ofthe broad leaved weed,but is harmful to the Zoysia turfgrass.So they can be chosen to use in before establishmentand management of turf grass.Different weed floras were observed in the lawns thus herbicides should be selected ac-cording to their spectrum of control.
