摘　　要：通过大田随机区组试验设计,对栽培密度与糜子产量性状的关系进行研究。试验结果表明:在整个生育期内(氮、钾、磷肥正常施用情况下)。随着种植密度的增加,穗长、穗粒数、千粒重、茎粗及单产都表现出降低趋势,密度18万株/hm2的产量较密度26万株/hm2增产在5%左右,得出了糜子的最适宜栽培密度。The experiment was conducted with the random-blocks design in field. The relatio ically studied between different density of proso millet. The results showed that during the nship is systematperiod stage to the booting stage （ in the case of N, P, K fertilizer is used as usual） With the increase of de of jointing nsity at the same time, ear grains, the number of grains, thousand grain weight, stem thick, ear length reduced ear grain. The yield 180 000 every hectare are higher 5% than that of the 260 000 every hectare. Then, the suitable density was concluded.
