【摘要】 大花萱草(H em eroca llis hybrid a)移栽定植后,用不同浓度稀禾定、吡氟禾草灵进行了茎叶喷雾防除大花萱草田杂草试验,结果表明,稀禾定和吡氟禾草灵能有效防除禾本科杂草,对成株阔叶杂草防除效果很差;药后45 d,1 200~1 800 mL/hm212.5%稀禾定、1 050~1 575 mL/hm215%吡氟禾草灵对禾本科杂草的防除效果均较好,对大花萱草植株安全无害。更多还原

【Abstract】 Post-emergence herbicides were used to spray stems and leaves.The experiment results show the post emergence herbicides could control gramineous weeds in Hemerocallis hybrida,but had no effect on adult broad-leaved weeds.45 days after spraying,the control effects of 1 200-1 800 mL/hm~2 sethoxydim or 1 050-1 575 mL/hm~2 fluazifop were good.It was secure to use the above dosage of herbicides on Hemerocallis hybrida.更多还原
