Abstract
Based on the lysimeter experimental data,the effect of irrigation and drainage coupling management on the variation of rice water requirement was analyzed. The results show that the irrigation and drainage coupling management has a significant influence on rice water requirement(p0.05). Compared the controlling irrigation patlerns with the conuentional sufficient irrgation pattern,the water clemand of the whole rice growth in the cares of suitable or contralled groundwater table were reduced 25.3% and 34.4%,respectively. The rice water requirement intensity also declined,obviously at shooting-booting and mid-tillering stage. The water requirement coefficients varied from small to large,then large to small in the whole rice growth. The contrast of water requirement between the irrigation and drainage coupling management modes shows little difference between different groundwater depth,and rice need less water under the controlled mode.
