摘要
为了确定酒泉地区紫花苜蓿适宜的播种量,本研究以BR4010品种为试验材料,设置450万、600万、750万、900万、1050万粒/hm^2共5个不同密度梯度进行试验,研究对紫花苜蓿产量和质量的影响。结果表明,产量以播种量在600万粒/hm^2~900万粒/hm^2时最高,经过综合筛选,600万粒/hm^2为该地区最佳播种量。
In order to determine the suitable planting density of Alfalfa in Hexi region,this research takes BR4010 varieties as material,the effect of 5 different planting densities on yield and quality of alfalfa was studied,which were 450×10^4、600×10^4、750×10^4、900×10^4、1050×10^4 plants per Hectare. The results show when the planting density was 400×10^4 to 600×10^4 per Hectare,the yield was higher,After a comprehensive analysis,the best planting density was 400×10^4 per Hectare.
