摘要
为了优化洞庭湖区温光等资源配置,提高轻简化生产水平,本研究探讨了洞庭湖区主要种植模式的限制因素和不足之处,从温光资源、用养结合、产品质量和种植效益4个方面系统分析了洞庭湖区油-稻两熟制种植模式的优势,并提出发掘油-稻种植模式潜力的问题和展望,建议湖区发展以免耕直播、机械化收脱、秸秆粉碎还田等技术为主的油-稻水旱轮作种植模式,为洞庭湖区资源优化配置和丰产高效种植模式创新提供参考依据。
In order to optimize the allocation of heat and light in Dongting Lake area, and improve the level of light and simplified production, we discuss the limiting factors and deficiencies of main planting patterns inthis area, and analyze the advantages of cropping pattern of rapeseed-rice rotation in the area from fouraspects: heat-light resource, combination of utilization and nurturing, product quality and planting benefits.Then, we point out the problems and prospects of the rapeseed-rice cropping system, and suggest a rapeseed-rice rotation system of no-tillage direct seeding, mechanized harvesting and threshing, and straw crushing andreturning, thus to provide references for the optimized configuration of resources and high-yield and high-efficiency planting mode in Dongting Lake Area.
