除草剂对麻黄田间杂草防除及麻黄的安全性
|
摘要
[目的和方法]明确麻黄田间化学除草使用的除草剂和剂量,开展杂草调查和化学防除试验。[结果]麻黄田间杂草主要为阔叶杂草;10%草甘膦AS和72%2,4-滴丁酯因为对麻黄苗产生伤害,不能在麻黄田间使用;防除麻黄田间阔叶杂草,应使用600 mL/hm~2的24%乳氟禾草灵EC和500 mL/hm~2(制剂用量)的10%乙羧氟草醚EC;防除禾本科杂草时,使用6000 mL/hm~2(制剂用量)的20%烯禾定EC,效果最好;而60 g/hm~2(制剂用量)的75%苯磺隆DF既能防除禾本科杂草,又对阔叶草有效,是麻黄田间首选的除草药剂。
[Aims and Methods] To study the effective herbicides and application dosage, we investigated weeds in Ephedra sinica field and tested chemical weed control. [Results] The results showed that the weeds in Ephedra sinica field were mainly broadleaf weeds. Glyphosate 10% AS and 2,4-D butyl ester 72% EC can not be used because the damage to E. sinica seedling. Lactofen 24% EC and fluoroglycofen-ethyl 10% EC were better for controlling broadleaf weeds and the dosages were 600 and 500 mL/ha, respectively. The control effect of sethoxydim 20% EC on grassy weeds was the best and its dosage was 6000 m L/ha. Tribenuron 75% DF was the preferred herbicide in E. sinica field considering its good control on both grassy weeds and broadleaf weeds.
