采用三因素随机区组设计,通过2个玉米品种和5个大豆品种间行和同穴混种的方式,研究大豆产量性状、蛋白质含量和脂肪含量的变化。结果表明:玉米品种、大豆品种和种植方式影响大豆产量,但差异不显著。玉米品种和大豆品种的组合对大豆单株产量有显著影响,登海11玉米与南豆12大豆组合的大豆单株产量最高。大豆品种和种植方式的组合对单株产量有显著影响,凉2032大豆与玉米同穴种植的单株产量最高。玉米品种、大豆品种和种植方式对大豆的脂肪和蛋白质含量有一定程度的影响。玉米大豆间作和混作对大豆产量和品质有不同的影响,生产上应根据栽培目的选用相应的品种和种植方式。
A three-factor randomized block design was adopted to study the changes of soybean yield traits, protein content and fat content through the intercropping of two maize varieties and five soybean varieties. The results showed that: corn varieties, soybean varieties and planting methods affect soybean yield, but the difference was not significant. The combination of maize varieties and soybean varieties had a significant effect on the per plant yield of soybean, and the combination of Denghai 11 and Nantou 12 soybean had the highest yield per plant. The combination of soybean varieties and planting methods had a significant effect on the yield per plant, while the yield per plant of cold 2032 soybean and corn was the highest. Maize varieties, soybean varieties and planting methods have a certain impact on the fat and protein content of soybean. Intercropping and intercropping of corn and soybean have different effects on the yield and quality of soybean, and the corresponding varieties and planting methods should be selected according to the purpose of cultivation.
