总结了湖南省衡东县2012—2014年实施“双季超级稻高产栽培技术研究应用”项目的试验情况及效果。通过3年的实践,衡东县摸索出了适合南方稻区双季超级稻高产栽培模式和技术路线图,筛选出适应性广、多抗、高产和质优的超级稻组合,合理搭配早、晚稻品种,综合组装、测土配方施肥、分段施肥、合理水浆管理,综合防治病、虫、草害等先进农艺技术措施的应用,使稻谷单产超过9 000 kg/hm2。
This paper summarizes the experimental conditions and effects of the project “Research and Application of Double-cropping Super-high Yielding Cultivation Techniques” in Hengdong County, Hunan Province from 2012 to 2014. Through 3 years of practice, Hengdong County worked out a high-yielding cultivation model and technology roadmap for double cropping rice in the southern rice region and screened a super rice combination with wide adaptability, multi-resistance, high yield and high quality, The application of advanced agronomic techniques such as late rice varieties, integrated assembly, soil testing and fertilizer application, segmented fertilization, reasonable water slurry management, integrated disease control, insect pests and grass weeds have resulted in a yield of more than 9 000 kg / hm2 of rice.
