通过对小麦、玉米周年连作宽垄沟灌试验,观测水流在灌水沟中的推进与消退过程,主要研究了不同垄宽规格对沟灌水流特性的影响。试验结果表明:水流的推进速度随着垄宽规格的增大而减小,幂函数可以较好的模拟水流推进过程,相关度都较高;水流的消退速度则随着垄宽规格的增大而增大,水流的消退过程也符合幂函数关系,而且水流消退较水流推进对垄宽规格更为敏感。WinSRFR软件能较好地模拟地面水流推进与消退过程,因此可以用其模拟周年连作宽垄沟灌不同沟灌技术要素下的地表水流运动。研究结果可为改进地面灌溉方法提供一定的技术参考。
通過對小麥、玉米週年連作寬壟溝灌試驗,觀測水流在灌水溝中的推進與消退過程,主要研究瞭不同壟寬規格對溝灌水流特性的影響。試驗結果錶明:水流的推進速度隨著壟寬規格的增大而減小,冪函數可以較好的模擬水流推進過程,相關度都較高;水流的消退速度則隨著壟寬規格的增大而增大,水流的消退過程也符閤冪函數關繫,而且水流消退較水流推進對壟寬規格更為敏感。WinSRFR軟件能較好地模擬地麵水流推進與消退過程,因此可以用其模擬週年連作寬壟溝灌不同溝灌技術要素下的地錶水流運動。研究結果可為改進地麵灌溉方法提供一定的技術參攷。

The process of the irrigation groove is observed whose water was advanced and subsided by the wide ridge furrow irrigation experiment of continuous and yearly cropping wheat‐corn .And this paper mainly does research on the effect of different ridge width specifications on the flow characteristics of furrow irrigation .The results show :The speed of water advance decreases as the ridge width specifications increases .Power function can fit the process of water advance well .While the speed of water subsided increases as the ridge width specifications increase .The flow of the subsiding process also accords with power function relationship ,and it is more sensitive to the ridge width specifications than the flow of advancing process .WinSRFR software can simulate the process of ground water advancing and subsiding well .Therefore ,it can be used to simulate the surface flow with different furrow irrigation fac‐tors ,under the condition of the wide ridge furrow irrigation experiment of continuous and yearly cropping wheat‐corn .The results can provide some technical reference values for improving surface irrigation methods .
