玉米大豆间混种植对大豆产量和品质的影响

Effects of Intercropping or Mixed Cropping with Corn on Yield and Quality of Soybean

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 with two corn cultivars,five soybean cultivars and intercropping or mixed cropping to study the change of yield traits,protein and fat content of soybean.The results showed that corn cultivars,soybean cultivars and planting methods affected soybean yield,but the differences were not significant.The combinations of corn cultivars and soybean cultivars or soybean cultivars and planting methods had a significant effect on soybean yield.The combinations of corn cultivars Denghai 11 and soybean cultivars Nandou 12 got the highest soybean yield.Soybean cultivars Liang 2032 mixed cropping with corn could get the highest soybean yield.Corn cultivars,soybean cultivars and planting methods had some effects on fat and protein content of soybean.Intercropping or mixed cropping with corn had different effects on yield and quality of soybean,and corresponding cultivars and planting methods should be selected and used based on production objective in practice.
