大豆-玉米带状复合种植株行距优化

Optimization of Plant and Row Spacing for Soybean-Maize Strip Compound Planting

合理的株行距配置可使大豆-玉米带状复合种植增产增收。为明确适宜界首市推广的大豆-玉米带状复合种植株行距,文章采用6∶4(大豆∶玉米)种植模式,研究4种不同株行距配置对大豆-玉米带状复合种植产量和产值的影响。结果表明,在大豆∶玉米6∶4种植模式下,品种组合1、2、3适宜株行距配置为大豆∶12 cm×30 cm,玉米∶12 cm×60 cm;品种组合4、5适宜株行距配置为大豆∶12 cm×30 cm,玉米∶14 cm×50 cm。在此株行距配置下,各品种组合的产量及产值最高,适宜在界首市推广应用。

Reasonable spacing between plants and rows could increase yield and income in soybean-maize strip intercropping.To clarify the suitable plant row spacing pattern for soybean-maize strip intercropping in Jieshou City,this article adopted 6:4(soybean:maize)planting pattern and studied the effects of four different plant row spacing configurations on the yield and output value of soybean-maize strip intercropping.The results showed that under the 6:4 planting mode of soybean and maize,the suitable spacing configuration for variety combinations 1,2,and 3 was soybean:12 cm×30 cm and maize:12 cm×60 cm;The suitable spacing configuration for variety combinations 4 and 5 was soybean:12 cm×30 cm and maize:14 cm×50 cm.Under this spacing configuration,the yield and output value were the highest,making it suitable for promotion and application in Jieshou City.
