【摘要】 [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。更多还原

【Abstract】 [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.更多还原
