摘要 2010-2011年,对豌豆与小麦在高寒阴湿区不同间作比例下的生育期、叶面积指数及综合产量等进行研究。结果表明:间作可明显延长豌豆的生育期,提高豌豆叶面积指数、综合产量及经济效益。其中处理M2D2即小麦与豌豆按2∶2行比例间作生育期最长,叶面积指数最高,土地当量比最大,具有明显的产量优势,2010和2011年间作综合产量分别较小麦单作(MT)提高58.11%和38.55%,较豌豆单作(DT)提高29.70%和50.87%;全年经济效益分别较小麦单作(MT)的提高112.66%和83.45%;较豌豆单作(DT)提高4.97%和22.08%。因此,豌豆小麦间作模式增产的关键在于行比的合理搭配。 The results of 2 years （2010--2011） field experiment indicated that intercropping had pro- longed the growing season, increased leaf area index, comprehensive yield and economic efficiency. The best planting pattern was intercropping of wheat and pea at 2 ： 2 （M2D2）. In 2010 and 2011 ,the com- prehensive yield in treatment M2D2 increased by 58.11% and 38.55% compared to wheat monocul- ture （MT） ,and 29.70% and 50.87% higher than pea monoculture （DT） ,respectively; the economic efficiency in treatment M2D2 increased by 112.66% and 83.45%, as compared to wheat monoculture （MT） and 4.97% and 22.08% respectively,as compared to pea monoculture （DT）. So,the yield gain might be related to reasonable arrangement of row proportion in the intercropping.
