晋南半夏与小麦玉米间套作模式研究

Intercropping Patterns of Wheat/Pinellia ternate/Corn in Southern Shanxi

对小麦、半夏和玉米的多种间套作模式进行了田间小区试验,分析不同种植模式的产量及效益差异。结果表明,以小麦窄-宽-窄行的方式套作半夏,虽然小麦减产0.45%,但套种的半夏生长健壮;夏玉米与半夏不同间作模式的产量存在显著或极显著差异,以半夏播量为480 kg/hm2,与玉米品种晋单63号、郑单958宽窄行间作的种植模式较佳,半夏及玉米产量较高,该模式纯收益比小麦、玉米轮作高出2.773万元/hm2。

Intercropping patterns of wheat/Pinellia ternate/corn in southern Shanxi were studied. The results showed as follows：the wheat yield only decreased by 0.45% when intercropping Pinellia ternate in the wide wheat-row, but Pinellia ternate intercropped grew well. The yield variance of Pinellia ternate and corn was significant or extremely significant between different intercropping patterns. The better intercropping patterns were replying Pinellia ternate in the wide wheat-row, intercropping Pinellia ternate with corn cropped by wide-narrow row pattern, with corn variety Jindan 63 and Zhengdan 958 and 480 kg/hm^2 planting quantity ofPinellia ternate. The net income of this pattern was 27.73 thousand yuarn/hm^2, which was higher than that of wheat/corn rotation.
