摘要
为明确鲁西北地区适宜间作的大豆/玉米组合品种,以9个不同间作大豆/玉米品种组合为研究对象,采用灰色关联度分析法对不同间作组合中的大豆和玉米农艺性状、产量及效益进行综合分析与评价。研究结果表明:(大豆)齐黄34×(玉米)登海605、(大豆)冀豆12×(玉米)登海605组合中参试大豆品种与理想参考品种加权关联度分别为0.938 1和0.937 8,大豆产量分别为2 155.17和2 119.54 kg·hm^-2;参试玉米品种与理想参考品种加权关联度分别为0.987 5和0.939 2,玉米产量分别为5 700.69和5 592.18 kg·hm^-2,这两个间作组合中大豆、玉米综合性状表现最为优良,且综合产量较高,综合经济效益较好,适宜在鲁西北间作大豆/玉米种植模式中大面积推广种植。
Aiming to identify the suitable combination varieties in the northwest of Shandong province, we took nine different intercropping soybean/maize varieties combinations as research objects, and adopted the grey correlation analysis method to comprehensively analyze and evaluate the agronomic characters, yield and economic benefit of soybean and maize. The results showed that:(soybean) Qihuang 34×(maize) Denghai 605,(soybean)Jidou 12×(maize) Denghai 605 combination of the tested soybean varieties and the ideal reference varieties of the weighted correlation degree were 0.938 1 and 0.937 8, respectively, the soybean yield were 2 155.17 and 2 119.54 kg·ha^-1. The weighted correlation between the tested maize varieties and the ideal reference varieties was 0.987 5 and 0.939 2 respectively, and the maize yield was 5 700.69 and 5 592.18 kg·ha^-1, respectively. The comprehensive traits of soybean and maize of the two intercropping combinations were the best, and the yield, economic benefit were both higher, which were suitable for large-scale extension and planting in the intercropping mode of soybean/maize in northwest Shandong.
