[目的]解决44％谷友WP在推广中的药效不佳或药害问题。[方法]采用四因素四水平和三因素二水平的正交试验和新复极差法统计分析，针对施药剂量、喷灌水量、整地质量、土壤墒情等影响因素进行了44％谷友（单嘧·扑灭）WP防控杂草及其对谷子产量影响的比较试验。f结果17个试验因素对44％谷友WP防控杂草效果均具有重要的影响，其中，施药剂量、灌溉水量、整地质量、土壤墒情还是影响谷子产量的最重要因素。根据符子产量和经济效益，确定了44％谷友WP经济、安全、高效防控谷田杂草技术的最优方案：44％符友WP的剂量为1800g／hm^2，在播种后出苗前进行土壤处理；耕耙地要坚实；土壤含水量要达到15％；药后不进行喷灌；在45天高药效持续期内能有效控制谷田杂草，尤其是双子叶杂草。[结论]该研究将为谷田杂草综合防控技术、确保谷子丰产丰收提供有益帮助。

[Objective] The paper was to resolve the poor efficacy or phytotoxicity problems in promotion of herbicide monosulfuron plus propazine 44% WP. [Method] Using orthogonal test and Duncan＇s new multiple range statistical analysis with four factors four levels and three factors two levels, the effects of factors such as herbi- cide dose, irrigation water volume, quality of soil preparation and soil moisture content on chemical control of monosulfuron plus propazine 44% WP against weeds and millet yield were compared in the test. [Result] Seven factors all had great impact on control effect of monosulfuron plus propazine 44% WP against weeds, of which her- bicide dose, irrigation water volume, quality of soil preparation and soil moisture content were the most important factors affecting millet yield. According to millet yield and economic benefit, the optimal scheme to ensure safe, efficient and economic control of monosulfuron plus propazine 44% WP against weeds was as follows： the dose of monosulfuron plus propazine 44% WP was 1 800 g/hm2, the soil was treat- ed after sowing and before seedling emergence; the soil should be smooth and sol- id; the soil moisture should reach 15%; the fields should not be irrigated after herbi- cide application, and the damage of weeds in millet fields could be effectively con- trolled within 45 d during high efficacy duration, especially the damage of dicotyledonous weeds. [Conclusion] The study provided useful information for comprehensive technology of weeds control and ensuring high yield and good harvest of millet.
