选择亚热带北缘(32°N)的江苏沿江苏南地区作为建模研究区。1979年以来,研究了玉米-稻种植模式的温度和土壤适应性、光热资源利用效率、能量转换效率、农牧结合效率和轮作效应等生态特性;形成玉米-稻种植模式的省工高产配套技术;在生产实践中应用,取得较好的社会、经济、生态效益。研究结果显示,该种植模式在南方稻区具有广阔的应用前景。
The subtropical north margin (32 ° N) was chosen as the modeling study area along the southern Jiangsu coast of Jiangsu Province. Since 1979, the ecological characteristics of maize-rice cropping system such as temperature and soil adaptability, light and heat resource utilization efficiency, energy conversion efficiency, efficiency of combination of agriculture and animal husbandry and rotation effect have been studied. Technology; application in production practice, to obtain better social, economic and ecological benefits. The results show that the planting pattern has a broad application prospect in southern rice area.
