摘要
文章以玉米单作和大豆单作为对照,设置了3个玉米种植密度,研究了玉米种植密度对玉米、大豆间作产量及产值的影响。结果表明:随着玉米种植密度的增加,玉米产量及产值逐渐提升,大豆产量及产值逐渐降低。玉米与大豆种植规格为2∶3型(即2行玉米,3行大豆),玉米种植密度为25 000~30 000株/hm^(2),大豆种植密度为210 000株/hm^(2)时,玉米及大豆产值为最高,是最适宜贵州省贵阳市的玉米、大豆间作模式。
In this paper,three maize planting densities were set with maize monoculture and soybean monoculture as the control,and the effects of maize planting density on maize and soybean intercropping yield and output value were studied.The results showed that with the increase of maize planting density,maize yield and output value increased gradually,while soybean yield and output value decreased gradually.Maize and soybean planting specifications are 2∶3 type(2 rows of maize,3 rows of soybean),maize planting density is 25000~30000 plants/hm^(2),soybean planting density is 210000 plants/hm^(2),maize and soybean production value is the highest,which is the most suitable maize and soybean intercropping mode in Guiyang City.
