摘要
设置玉米-大豆不同带距行距间作,研究高秆强势作物玉米对矮秆弱势作物大豆的生长及产量等的影响,旨在为玉米-大豆间作共生体系的高产复合作物群体提供合理的田间配置技术参数。结果表明:玉米-大豆带距或行距越小,大豆株高和底荚高越高,但分枝数、有效荚数、单株粒数、单株粒重则越少;带距或行距越小,玉米株高、穗位高越高,但穗长、单穗重、穗行数、秃顶长和行粒数越少。带距或行距越大,玉米和大豆产量越高。在0.65 m带宽下,玉米和大豆产量均在行距0.5 m时表现最高,为玉米-大豆间作的最佳配置方式。
The effects of different band and row spacing on growth and yield of intercropping maize and soybean were studied,aiming to provide rational field arrangement theoretical parameters for high-yield community of maize and soybean intercropping symbiosis.The results showed that the lower the band or row spacing of maize and soybean,the higher the plant height and bottom pod height of soybean were,but the fewer of branches,effective pods,grain numbers and grain weight of single plant.And the lower the band or row spacing of maize and soybean,the higher the plant and ear height of maize,but the smaller of ear length,single ear weight,ear line number,balding length and row grain number.Meanwhile,the yields of maize and soybean increased with the increasing of band or row spacing,and reached the largest with 0.65 m bandwidth and 0.5 m row width,which was the optimal allocation for intercropping maize and soybean.
