我省玉米大豆间种始于60年代后期,70年代风行一时,至80年代的今天,不少市县仍广为采用.在玉米大豆间作中,有各种各样行比.有大豆行多,玉米行少的高窄矮宽间作方式,有玉米大豆行数相等(6:6、7:7)间作方式,但大量的是玉米行多,大豆行少的高宽矮窄间作方式,多用于上等地力以生产玉米为主的地块.由于行比不同,地力不同,生产目的不同,要全面而恰当地弄清各种间种方式的利弊是很困难的.下面仅就高宽矮窄间作方式作一些分析. The province of corn and soybean between the species began in the late 1960s, 70’s popular, to the 80’s today, many cities and counties are still widely used in intercropping corn, there are a variety of lines. , Corn lines less high and narrow short and wide intercropping methods, the same number of rows of corn and soybeans (6: 6, 7: 7) intercropping methods, but a large number of corn lines, Due to the different ratio, different ground force and different purpose of production, it is very difficult to fully and properly understand the advantages and disadvantages of various kinds of ways. Narrow intercropping for some analysis.
