摘　　要：采用随机完全区组设计,研究不同浓度速收与肥料混用对谷子出苗率及株高的影响,以及对谷子田杂草的防除效果。结果表明,速收180g/hm2和肥料300kg/hm2混用对谷子出苗率及株高的抑制均未达显著水平,对谷子田阔叶杂草的防效可达90%以上,对禾本科杂草的防效稍差于阔叶杂草,但也可达到80%左右,说明该处理是谷子田最理想的除草施肥一次性作业方法,既对谷子安全又具有较好的除草效果。Randomized completely block design was employed to study the effect of different concentration of Sumisoya her- bicide-fertilizer on seedling emergence rate and plant height of millet, as well as the effect of which on weeds in millet fields. The effect of Sumisoya of 180 g/hm2 mixed with fertilizer of 300 kg/hm2 on seedling emergence rate and plant height were not signifi- cant, and control effect for broadleaf weeds above 90%. Control effect of this mixture on grass weeds was slightly poorer than on broadleaf weeds but could up to about 80%. The most ideal scheme of mixing herbicide and fertilizer in millet was a mixture with Sumisoya of 180 g/hm2 and fertilizer of 300 kg/hm2, which was safe to millet and had good control effect on weeds in millet fields.
