【摘要】 从紫山药生姜间作的平衡生产系统角度出发,研究了紫山药‖生姜种植模式的平衡生产力、物质生产效率及经济收益,并集成了相应的配套技术。结果表明:紫山药‖生姜模式H₄处理在平衡生产力上优势显著,与传统生姜单作、紫山药单作比较,其生姜、紫山药产量分别提高了42.5%和33.5%,其产投比分别提高了45.8%和30.4%,具有高产、高效种植的特点;在资源利用效率上也表现出较高的温热资源集约和节水利用效率。更多还原

【Abstract】 From the view point of balanced production system of purple yam-ginger intercropping, we studied and compared the balanced productivity, matter production efficiency and economic benefits of different purple yam ‖ ginger planting models, and integrated the corresponding matching technologies. The experimental results showed that purple yam ‖ ginger planting model H₄ had significant advantages in balanced productivity, it obtained 42.5% higher ginger yield and 33.5% higher purple yam yield than the traditional ginger monoculture and purple yam monoculture, respectively, and its output-input ratio increased by 45.8% and 30.4%, separately. So this intercropping model had the characteristics of high yield and high efficiency. Furthermore, this model also exhibited higher resources（heat and water） use efficiencies.更多还原
