摘要:为建立湘南双季稻区节水灌溉栽培模式提供依据,设置了不同灌溉方式对水稻生长发育的影响试验。试验结果表明:不同灌溉方式在水稻生长、干物质积累、生理特性以及产量上都存在显著差异。4种灌溉方式下水稻生长与产量表现以浅水灌溉最优,受旱灌溉最差, 与受旱灌溉比,浅水灌溉株高、分蘖数、光合速率均有提高,%, g, g/盆;浅水灌溉下水稻产量、 g/ kg/m3。间歇灌溉产量与深水灌溉差异很小, kg/m3。因此,在湘南双季稻区,针对季节性干旱的特点,采用浅水灌溉方式有利于晚稻高产稳产,间歇灌溉有利于晚稻种植。

Abstracts: The rice growth and yields under four different irrigation methods were studied. The results showed that different irrigation method had significantly different impact on the rice growth, physiological characteristics, the dry matter accumulation and the production. The shallow irrigation was the optional method for rice growth and pared with other irrigation methods, and the dry irrigation method was the worst. Compared with the dry irrigation method, plant height, the tiller number and photos
