摘　　要：【目的】探讨东北地区谷田施用10％单嘧磺隆wP后对主要后茬作物的安全性。【方法】2010—2011年在黑龙江省采用田间小区试验方法进行了土壤残留12个月对后茬作物影响试验。【结果】按照30、45ga．i．／hm^2施用10％单嘧磺隆WP12个月后，马铃薯、大豆、向日葵、高粱、玉米的出苗不受影响，对作物的株高、鲜质量、产量的影响没有一定规律，与空白对照都差异不显著。【结论】10％单嘧磺隆wP按照推荐剂量15～30ga．i．／hm^2使m12个月后可以安全种植马铃薯、大豆、向日葵、高粱、玉米5种后茬作物。[Aims] The effect of monosulfuron 10% WP soil residues on succeeding crops 12 months after application on millets soil was studied. [Mothocls] Small pilot field experiments were conducted in 2010 and 2011 in Heilongjiangprovince. [Results] With monosulfuron 10% WP at the rate of 30 and 45 g a.i./ha, the emergence of potatoes, beans, sunflowers, sorghum and corns were not affected. The influence on plant height, fresh weight and yield of succeedingcrops had no certain law, and the comparison with blank control had no significant difference. [Conclusions] After 12 months application of monosulfuron on millets at recommended rate of 15-30 g a.i./ha, the following post-crops suchas potatoes, beans, sunflowers, sorghum, corns can be safely planted.
