- 摘要:
- 对元谋干热河谷区4种旱坡地生态农业模式进行连续2a的定位监测，研究各种模式的生态、经济和社会效益。结果表明：与对照模式罗望子+自然草被相比，建立的4种模式均有一定的培肥、改土效果，其中，以豆科牧草为主的罗望子+木豆、罗望子+木豆+柱花草、罗望子+木豆+绿肥3种模式的效果明显优于以禾本科牧草为主的罗望子+象草模式；4种模式均能在旱季提高土壤含水量，明显改善局地小气候；同时，产生良好的经济和社会效益。
- Abstract:
- Long-term stationary monitoring for 2 years in a row was conducted with 4 different models of compound eco-agriculture on dry slope land, and studies of the 4 models’s ecological benefit, economic benefit and social benefit were carried out.The results showed that the models’s effects of soil fertile and soil improvement were better than the compared model which was Tamarindus indica+natural grass.Among them, the effects of 3 models, Tamarindus indica+pigeon pea, Tamarindus indica+pigeon pea+Stylosanthes gracilis and Tamarindus indica+pigeon pea+green manure in which the main herbage was the pea family were clearly better than Tamarindus indica+Percisetum purpureum in which the main herbage was the grass family; all of 4 models could increase the soil moisture contents, improve partial weather conditions obviously in the dry season; and meanwhile produce good economic benefit and social benefit.
