摘　　要：通过对9个试点糜子不同保苗密度与产量的分析,确定了甘肃省四大生态区域适宜的糜子保苗密度为中部干旱区67.5万～112.5万株/hm2,高寒阴湿区45.0万株/hm2,陇东半湿润干旱区67.5万株/hm2,陇东半湿润偏旱区112.5万～135.0万株/hm2,河西灌区135.0万株/hm2。The different seedling density and yield of the nine pilot millet were analysis,and the seedling density of suitable for the millet planting were determined under the four major ecological regions of Gansu province which the central arid area was 675,000～1,125,000 plants/hm2,the alpine and humid region was 450,000 plants/hm2,semi-humid regions of Longdong was 675,000 plants/hm2,the semi-humid arid areas of Longdong was 1,125,000～1,350,000 plants/hm2,Hexi Irrigated areas was 1,350,000 plants/hm2
