水稻半耕节水高效栽培技术研究与应用

根据广东省潮安县灌溉科学试验站1998－2000年开展的专项试验，研究了不同耕作方法，用水技术、节水措施、栽培管理对水稻的生长发育，产量及其构成因素，水分生产率和生产成本，经济效益等的影响情况。试验结果与示范应用表明，与传统的全耕作和用水方式相比，并耕栽培技术可提高水分生产率，节支节水，增产增效，是目前本地最优的一种节水高效的稻田栽培管理模式。

Research on the Water-Saving and High-Efficiency Technique of Semi-Plough of Paddy Rice and Its Application

Impacts of different plough methods, water use technique, water-saving technique, cultivation management on the growth, yield, components, water productivity, production cost, economic benefit, and other aspects are researched according to the special experiment of 1998-2000 in the Irrigation Experiment Station of Chaoan County, Guangdong Province. The experiment results and demonstration application show that the semi-plough technique can increase water productivity, save water and expenses, increase yield and efficiency compared with traditional plough and water use techniques, so it is an optimal paddy field management mode of water-saving and high-efficiency.
