中文摘要	为研究干旱雨养旱作农业区降雨量对糜子产量的影响,20122017年在忻州市河曲县测定6年期间的降雨数据和糜子产量数据。结果表明:7月份是糜子生育期需水量最关键的月份,当月降雨量约占生育期总降雨量的38.03%~39.92%,降雨量与糜子产量呈极显著正相关,直接决定糜子能否高产;6月份决定糜子出苗率,当月降雨量约占生育期总降雨量的22.49%~22.65%,降雨量与糜子产量呈不显著正相关;8和9月份的降雨量与糜子产量显著负相关。结果表明,在6和7月份降雨量满足的情况下,当地糜子获得较好产量的生育期适宜降雨量为409.3~472.2 mm。
英文摘要	The objective was to study the impact of variation of rainfall on broomcorn millet yield in arid region, measured the date of rainfall and broomcorn millet yield of Hequ County from 2012 to 2017.The results showed that:July was the most critical month of water demand during the growth period of broomcorn millet,and extremely significant positive correlation with the yield of broomcorn millet,directly determined the broomcorn millet whether could achieve high yield,and the rainfall proportion accounted for about 38.03%-39.92% of the total rainfall during the growth period;The rainfall of June was no significant positive correlation to the yield of broomcorn millet,which determined the seedling emergence rate of broomcorn millet,and the rainfall proportion accounted for about 22.49%-22.65%of the total rainfall during the growth period.The rainfall of August and September was significantly negatively correlated with the yield of broomcorn millet.Therefore,under satisfying rainfall condition of June and July,the suitable rainfall during the growth period of broomcorn millet was 409.3-472.2 mm.
