摘要
本文阐述了包头城区草坪中的杂草种类,发生特点和规律,研究出适合包头城区草坪杂草的化学防除技术。结果表明:苯达松1 500ml/hm2-3 600ml/hm2是成坪草坪中阔叶杂草(4叶-15叶)的茎叶处理剂;除杂1号80ml/hm2-120ml/hm2是成坪草坪中1a生禾本科杂草的茎叶处理剂;除杂2号180ml/hm2-240ml/hm2作为土壤封闭剂;10%草甘磷水剂15kg/hm2加750g洗衣粉助剂是多年生恶性杂草白草的防除技术。在推荐药用量范围内,施药后未发现草坪出现任何药害症状,安全性较好。
The weed speciesis and infestation laws were studied in the garden lawn of Baotou.The results showed that： Bentazon 1 500ml/hm2-3 600ml/hm2 was herbicide on the stem and leaf of broad-leaved weeds in turf grass（4-15 leaves）;WeedicideⅠ80-120ml/hm2 was herbicide on the stem and leaf of annual grass weedsturf;WeedicideⅡ160ml/hm2-240ml/hm2 was a soil sealant;It was effective controlled Pennisetum flaecidum by 10% glyphosate aqueous 15kg/hm2 plus 750g washing powder.Within the recommended range of medicinal,lawn after application did not find any injury symptoms,and good safety.
