【摘要】 为探索单位耕地面积产值最高的种植模式,以单作玉米和单作甘薯为对照,研究玉米与甘薯间套作不同的种植模式。分四大类型进行,分别为单作玉米、单作甘薯、间作和套作,其中间作又分三个模式,玉米与甘薯种植行比为2∶1,2∶2,2∶3,套作分4个模式,甘薯以不同方式和密度套种在玉米行间,共计9个模式。结果表明,各类型产值高低顺序为单作甘薯>间作>单作玉米>套作,在9个种植模式中,以模式3玉米间作甘薯,玉米与甘薯行比为2:3的种植模式产值最高,是值得推广的种植模式。更多还原

【Abstract】 In order to explore planting modes with highest production value per unit land,to take single-planted maize and sweet potato as CK,an intercropping experiment was conducted with four modes and nine sub-patterns,The result shows that the output value sequence is sweet potato single planting,interplanting,maize single planting and intercropping and pattern No.3 of maize interplanting has the highest value with 2 lines of maize and 3 lines of sweet potato,which is worthwhile to extend in production.更多还原
