摘　　要：以蒙啤麦3号大麦为供试材料,在通辽市进行播种期、密度处理栽培试验。结果表明,通辽地区蒙啤麦3号以3月29—4月19日播种、密度以30万~40万株/667 m^2为宜;在4月4日播种,且密度为40万株/667 m^2条件下,蒙啤麦3号在通辽地区可实现理论产量422.9 kg/667 m^2。In order to provide a theoretical basis for malting barley cultivation in Tongliao region of Inner Mongolia,a field trial was conducted to assess the effects of planting density and sowing date on the yield of the malting barley variety Mengpimai 3 in Tongliao City. The results showed that the optimum sowing date for Mengpimai 3 was from March 29 to April 19 and that the suitable planting density was（ 30- 40） × 10^4 /667 m^2 plants. According to the data of the fitting test,when the sowing date was April 4 and planting density was 40 × 10^4 /667 m^2 plants,the theoretical yield of Mengpimai3 was 422. 9 kg /667 m^2 in Tongliao region.
