摘要
总结和归纳已有的研究成果,阐明了饲养动物在稻田生态系统中的生态经济效应、现有生态种养技术急需克服的关键技术及其发展动态;展望了饲养动物在水稻生产过程中的应用前景。稻田饲养动物有利于改善稻田生态系统的水体和土壤环境和提高生物多样性,使整个系统所受的人为干扰减少,自然属性提高。未来稻田种养系统需要加强高位虫害防治和减少生态种养技术的需水量,进一步促进种养技术的发展最重要的是推广和传播问题。
Previous research results were summarized and concluded, ecological economic effects of raising animal in the paddy field were illuminated, and the paper pointed out that we need badly to overcome key technologies and developments in the existing ecological planting and breeding technology. Further, the paper stated that its application prospect of raising animals in rice production. The paper suggested that their activities metabolism of raising animals was improved water and soil environment, increase its biological diversity,which make the whole system's human intervention decreased and natural quality increase. Meanwhile, it points out future complex ecosystems need to strengthen the upper of pest control and reduced water demand of ecological farming technology. Consequently, to further promote the development of planting & breeding technology, the paper suggests that it was not a problem of economic benefits, what's more, was the problem of promotion, propagation and excitation.
