[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、45 g a.i./hm2施用10%单嘧磺隆WP 12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15~30 g a.i./hm2使用12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。
[Objective] The research aimed to discuss the safety of the main stubble crop after the application of 10% monosulfuron WP in Gutian, Northeast China. [Method] In 2010-2011, field experiment was conducted in Heilongjiang Province to test the effect of residual soil for 12 months on the crop. [Result] The emergence of potato, soybean, sunflower, sorghum and corn was not affected after applying 10% monosulfuron WP for 30 and 45 g ai / hm2 for 12 months. The plant height, fresh weight, There is no certain law of influence, and no significant difference with the blank control. [Conclusion] The 10% monosulfuron WP could safely plant five kinds of following crop of potato, soybean, sunflower, sorghum and corn after using 12 months at the recommended dose of 15-30 g a.i./hm2.
