| 摘 要： | 麦棉多作套种循环农业模式是从麦棉多熟种植制度发展而来。本文采用实地调查、文献搜集和定位试验相结合的方法，总结了麦（小麦）棉（棉花）多作套种循环农业模式的发展演变进程以及典型模式和关键技术，分析了其生态、经济效应。结果表明，麦棉多作套种循环农业模式，可以利用生态位原理，发挥不同作物的优势和边际效应，在不降低棉花和小麦产量的基础上，增加土地收益和生产效率，同时具有保护地温、节水保墒、提高光能利用效率的功效。因此，构建麦棉多作套种循环模式，能够实现棉田生物多样性、维持棉田生态系统平衡、提高土地和资源利用效率，具有较高的生态经济价值和应用前景。

| Abstract: | The wheat/cotton circular agriculture model, which has a long history in China, was developed from wheat/cotton intercropping system. This research summarized the progress, typical model, and key technology involved in this system. The in-situ inspection and literature reviewing were employed in this research. The function of ecological system and inter-effects of multi-species in this intercropping system were analyzed as well through position experiment. The results indicated that the wheat/cotton circular agriculture model could perform the advantage of different crops and the border effect, and could keep biodiversity in the cotton field, maintain the balance of ecosystem, enhance land and natural resources usage efficiency without sacrificing the economic yield of cotton and wheat. Therefore, the wheat/cotton circular agriculture modelcan achieve higher ecological-economical values and has great potential in Chinese farming system. |
