摘要
为了筛选适宜延安市大豆玉米带状复合种植模式的高产、优质、成熟期适中的大豆品种,选用齐黄34、中黄 30、陕豆 125 等 12 个具有一定耐阴性和抗倒性的大豆品种进行比较试验.结果表明,在大豆玉米带状复合种植模式(大豆与玉米行比为 4∶2)下,齐黄 34、秦豆 2018、宝豆 6 号和汾豆 93 植株较高,株型收敛,丰产性好,产量分别为 2 595.45、1 946.55、2 041.50、1 884.45 kg/hm2;效益较高,群体产值分别为 39 611.06、35 314.25、34 200.99、35 010.92 元/hm2,可扩大示范推广面积.
Abstract
In order to screen soybean varieties with high-yield,high-quality and moderate maturity suitable for the soybean-maize strip intercropping system in Yan′an City,a comparative test was conducted on 12 soybean varieties,including Qihuang 34,Zhonghuang 30,Shandou 125,and others,which have certain shade tolerance and lodging resistance.The results showed that under the soybean-maize strip intercropping system(soybean-maize row ratio of 4∶2),Qihuang 34,Qindou 2018,Baodou No.6,and Fendou 93 exhibited taller plant height,convergent plant type,good productivity,and the yield reached 2 595.45,1 946.55,2 041.50,and 1 884.45 kg/hm2,respectively.These varieties also showed higher economic benefits,with gross output values of 39 611.06,35 314.25,34 200.99,and 35 010.92 yuan/hm2,respectively.It was suggested that their demonstration and promotion areas could be expanded.
