本文从经济可行性和生态适应性角度分析了大蒜‖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。
This paper analyzes the suitability of the garlic ‖ faba bean planting in the local area from the perspective of economic feasibility and ecological adaptability. Field experiments were conducted in Zhaoyi Village, Shangguan Town, the edge of Erhai Lake in the northern part of Erhai Lake. After field test and laboratory analysis, the dry matter accumulation, rhizobial changes, root distribution, crop growth rate Land equivalent ratio and other conditions. The results showed that intercropping increased dry matter accumulation in the late stage, increased chlorophyll content in garlic and increased photosynthetic efficiency in the later stage. Intercropping can promote the root growth of garlic and broad bean. Intercropping efficiency than single, intercropping increase yield of 15%. This study provides reference for increasing the biodiversity of local farmland and arranging the local planting structure reasonably.
