摘　　要：采用2个不同类型品种空育131和龙粳26为试验材料,研究33.3、25.0、20.0、16.7穴.m-24种不同插植密度对寒地水稻生长发育及产量性状的影响。结果表明：寒地优质水稻分蘖力强的品种其适宜插植密度为30 cm×（16.7~20.0）cm,分蘖力一般的品种其适宜插植密度为30 cm×（10.0~16.7）cm。The effect of different transplanting density（33.3、25、20、16.7 hill per m2）on growth and yield of rice in cold region was studied using two different types of varieties Kongyu131 and Longjing26 as testing materials.The results showed that the suitable transplanting density for high tillering ability of high quality rice varieties was 30 cm×（16.7~20.0） cm and the suitable transplanting density of general tillering ability of rice varieties was 30 cm×（10.0~16.7） cm.
