摘要
为达到减轻药害、降低损失的目的,研究了不同剂量的烟嘧磺隆在玉米绥玉7号苗期不同叶龄喷洒对玉米植株生长状态的影响,得出了其安全剂量和药害剂量及其施药时期。结果表明:烟嘧磺隆在叶期施药,剂量在1 500~2 000mL.hm-2时对玉米是安全的;在6~7叶期施药,剂量在2 500~3 000mL.hm-2时对玉米会产生药害。
For the purpose of relief phytotoxicity, reducing loss, the effect of different dosage of Nicosulfuron spraying at different leaf ages on the growth situation of Suiyu No. 7 was studied. It conclude the safety dose, phytotoxicity dose and their application stages. The results showed that 3-5 leaf age with safe to maize,spraying Nicosulfuron at 6-7 leaf age with 2 500-3 000 mL.hm^-2 could cause phytotoxieity,
