| 摘 要： | 马铃薯-玉米间套种植是陕南山区粮食作物的主要种植模式，文章通过设置两个帯型、三个密度，研究结果表明，1.67 m双套双带型中马铃薯的适宜密度为667 m 3 500株时产量最高、效益较好。1.1 m双套单带型中马铃薯的适宜密度为667 m 4 500株时，产量最高、效益较好。在帯型选择上应结合市场行情，以效益为指导，选择合适帯型，提高收入。

| Abstract: | Potato-maize interplanting is the main planting pattern for grain crops in mountainous area of South Shaanxi, the two planting strips and three densities were set up in this paper.The results showed that the potato yield was highest and efficiency was better when the density was 3 500 plants ·667m-2 under 1.67 meter range of double intercroppings with two strips, the potato yield was highest and efficiency was better when the density was 4500 plants ·667m-2 under 1.1 meter range of double intercroppings with single strip.In selection of suitable planting strips, we should combine it with the market situation and take efficiency as orientation to choose different planting patterns for increasing income ; |
