| 摘 要： | 选用吉单27、吉单505、江单1号三个品种为试验材料对偏垄栽培、垄距50 cm、垄距65 cm、垄距130 cm、Ⅱ1465五个玉米种植模式进行产量分析。结果表明：栽培模式产量依次为垄距50 cm（10 306.2 kg.hm-2）、垄距130 cm（9182.6kg.hm-2）、垄距65 cm（9 021.1 kg.hm-2）、Ⅱ1465（8 809.7 kg.hm-2）、偏垄（8 047.2 kg.hm-2）,综合生产成本和与当前农机具相配套建议推广垄距130 cm大垄为宜。

| Abstract: | Three varieties Jidan 27,Jidan 505,Jiangdan No.1 were used to analyze the yield of five cultivation mode followed by partial ridge,ridge distance 50 cm,ridge distance 65 cm,ridge distance 130 cm and Ⅱ1465.The results showed that：The yield of mode of ridge distance 50 cm was 10 306.2 kg·hm-2,the yield of mode of ridge distance 130 cm was 9 182.6 kg·hm-2,the yield of mode of ridge distance 65 cm was 9 021.1 kg·hm-2,the yield of modeⅡ1465 was 8 809.7 kg·hm-2 and the mode of partial ridge was 8 047.2 kg·hm-2.The mode of ridge distance 130 cm was recommended the most suitable mode after comprehensive analysis of production cost and agricultural implements. |
