水稻间歇灌溉试验研究

Experimental Study on Intermittent Irrigation for Paddy

稻田间歇灌溉和其它水分管理模式的对比试验研究指出 ,相对而言 ,水稻间歇灌溉水分管理模式最节水 ,且灌水次数及田间排水量最少 ;其节水的机理在于提高降雨利用率。

The compare test of rice intermittent irrigation to other water management model shows that the rice intermittent irrigation is the most water saving, and the less times irrigation and drainage. The reason of water saving is to full use precipitation and to reduce seepage and evapotranspiration.
