不同剂量烟嘧磺隆对不同叶龄玉米幼苗的药害影响OA
Study on Effect of Different Doses of Nicosulfuron on Suiyu No .7 at Different Leaf Ages
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1500~2000 mL・hm-2时对玉米是安全的；在6~7叶期施药，剂量在2500~3000 mL・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 grow th 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 ,spra-ying Nicosulfuron at 6 ~ 7 leaf age with 2 500 ~ 3 000 mL・hm-2 could cause phytotoxicity .
