摘 要: | 对小麦、玉米一年三收多熟种植模式与小麦复播玉米、小麦套种玉米两熟模式比较分析得出 :采用适宜的一年三收种植模式 ,小麦产量可以少减产或不减产 ,而玉米产量大幅度提高 ,全年增产 1 2 %~ 1 4%。一年三收种植模式在新疆光热资源最丰富的 6~ 8月 ,作物田间群体生长率 (CGR)、光能利用率较好 ,实现全年增产。

The Analysis of the Production Effect and the Crop Group Growth of Multiple Cropping in Talimu Basin |
| |
Abstract: | The comparative analysis results about the wheat-corn three harvests per year with the wheat multiple cropping corn and wheat interplant corn two harvests per year showed: Adopting suitable wheat-corn three harvests per year cultivation method could make the wheat yield decreasing little or not decreasing. Meanwhile, the corn yield increased by a big margin. The all year yield increased 12%~14%. Using the three harvests per year cultivation method in Xinjiang in the 6~8 months with the best light and heat natural resource, the crop growth rate(CGR) and the light utilization rate( Eu (%)) were comparatively better. So the all year yield of the wheat-corn three harvests per year increased. |
