In this paper, the field experiments were carried out to investigate the suitability of economic feasibility and ecological adaptability of Garlic ⅡVicia fava mode local suitability on Luoshijiang edge of the northern region of Erhai Lake in Zhaoyi village of Shangguan towns. Accumulation of dry matter, rhizobium change, root distribution, crop population growth rate and land equivalent ratio situation were studied with data obtained from the field experiment and the laboratory. The results showed that intercropping could increase the dry matter accumulation , enhance garlic chlorophyll content, and improve the efficiency of post-photosynthetic use. Intercropping model could promote the down growth of the roots of the garlic and beans. The efficiency of intercropping was higher than that of monocropping, intercropping yield and increased 15 %. The conclusion provided a reference to increase the local farmland biodiversity, reasonable arrangements for local planting structure.%本文从经济可行性和生态适应性角度分析了大蒜Ⅱ蚕豆模式在当地种植的适宜性.在洱海北部地区罗时江边上关镇兆邑村开展田间小区试验,经田间测定和样品经室内分析化验后,依据所得数据分析干物质累积规律、根瘤菌变化、根系分布、作物群体生长率土地当量比等状况.结果表明,间作能增加后期干物质累积量,能提高大蒜叶绿素含量,提高后期光合利用效率.间作模式可以促使大蒜和蚕豆的根系向下生长.间作比单作效率高,间作的增产率为15％.本研究为增加当地农田生物多样性,合理安排当地种植结构提供参考.
