现代稻作生产主要依赖于化肥、农药等大量化学性物质的投入来获得高产稳产,这不仅破坏了生态环境,也使稻米品质受到危害。而稻鸭共作生态农业是以稻作水田为条件,以稻为中心,家鸭田间网养的自然与人工相配合的生态工程系统,是有效控制常规稻作生态污染的重要技术途径。(一)品种选择要专业鸭子必须首选体型小、适应性广、抗
Modern rice production relies mainly on the input of a large amount of chemical substances such as fertilizers and pesticides to achieve high and stable yield, which not only damages the ecological environment but also impairs the quality of rice. The cooperative ecological agriculture of rice-duck is an ecological engineering system which is based on rice paddy field and rice as the center. The natural and man-made matching of domestic duck farm is an important technical way to effectively control the ecological pollution of conventional rice. (A) choice of species to be a professional duck must be preferred body size, wide adaptability, resistance
