|
摘要
[目的]研究鲁西北地区夏玉米间作大豆适宜模式。[方法]研究在鲁西北地区夏玉米间作大豆不同种植模式(2行玉米2行大豆、2行玉米3行大豆,3行玉米3行大豆,行距均50 cm)的生物学性状、作物产量,对各种植模式的经济效益等进行比较。[结果]在现代农业机械化生产条件下鲁西北地区夏玉米间作大豆适宜模式以三三式即3行玉米间作3行大豆,行距均为50 cm为佳,该模式与常规夏玉米种植方式相比,少收夏玉米340 kg/hm~2左右,增产大豆近2 200 kg/hm~2,增收7 500元/hm~2左右。[结论]该模式能够实现机械化收割,达到以生产粮食为主要目的,兼收夏大豆的高产、高效、节能的效果。
[Objective]To sudy on summer maize/soybean intercropping in different cultivation patterns in Northwest Shandong Province.[Method]The biological characteristics and crop yields of different summer maize intercropping soybean planting patterns in Northwest of Shandong(2 rows of maize, 2 rows of maize, 3 rows of soybean, 3 rows of maize, 3 rows of soybean with average row spacing of 50 cm) were studied through experiments.The economic benefits of different planting modes were compared and analyzed.[Result]Under the condition of mechanized production, the optimum mode of summer maize/soybean intercropping in Northwest Shandong was three-three or three-row maize intercropping with three rows of soybeans, and the row spacing was 50 cm.Compared with the conventional planting mode, this mode could reduce the yield of summer maize by 340 kg/hm~2, increase the yield of soybean by nearly 2 200 kg/hm~2 and increase the income by 7 500 RMB/hm~2,and it could realize the machine.[Conclusion] Mechanized harvesting can achieve high-yield, high-efficiency and energy-saving effect of harvesting summer soybean with grain production as the main purpose.
