直播稻栽培技术研究进展

Research progress of direct seeding rice cultivation techniques

[目的]了解我国直播稻栽培技术研究现状,为直播稻的研究和推广提供依据。[方法]通过文献检索,综述了直播稻的播种技术、施肥技术、杂草防治与抗倒伏栽培以及品种筛选等方面研究进展。[结果]直播稻的产量和抗性与水稻品种、播种期、播种量、播种方法、施肥及灌溉技术关系密切。[结论]应通过品种筛选、合理播种、科学灌溉和施肥、化学调控等措施争取高产和防止倒伏;应加大草害的防治研究,开发高效低毒除草剂;建议建立适应机械化直播的稻田耕种模式。

[Purpose]To understand the current research status of direct seeding rice cultivation,and to provide basis for the research and promotion of direct seeding rice.[Method]The research progress of direct seeding rice in sowing techniques,fertilization techniques,weed control,lodging resistant cultivation,and variety selection techniques was reviewed through literature search.[Result]The yield and resistance of direct seeding rice were closely related to rice variety,sowing time,sowing amount,sowing method,fertilization and irrigation technologies.[Conclusion]High yield and prevention of lodging should be achieved through variety selection,reasonable sowing,scientific irrigation and fertilization,chemical control,etc;increase research on weed prevention and control by conducting research on high efficiency and low toxicity herbicides;and establish a paddy field cultivation model suitable for mechanized direct seeding.
