为探索帚用高粱的经济性状、工艺性状与种植密度的关系,根据陇东南山区当地种植情况设置了6.5万株/hm2、7.5万株/hm2、8.0万株/hm2、8.5万株/hm2 4种植密度,通过试验证明,密度在7.5~8.0万株/hm2范围内,生长发育良好,倒伏率低,穗部工艺性状优良,是栽培的适宜密度。
To explore the economic characteristics of sorghum broom sorghum, the relationship between the traits and planting density, according to the local planting conditions of Nanshan in eastern Gansu set 6.5 million / hm 2, 75000 / hm 2, 80000 plants / hm 2, 85000 plants / hm 2 4 Planting density, proved by experiments, the density of 7.5 to 80,000 / hm2 range, good growth and development, lodging rate is low, the ear traits of good, is the appropriate cultivation density.
