Abstract

Controlled alternate furrow irrigation is one of the new irrigation methods. In order to research the adaptation of soybean, soil water movement and water utilization efficiency under controlled alternate furrow irrigation in the north China, the experiment was done with Lysimeter in Kaifeng. The results show that compared with conventional furrow irrigation (CFI), the controlled alternate furrow irrigation has suitable irrigation quantity that is not only helpful for enhancing water use efficiency, increasing yield, but also helpful for reducing deep percolation. Therefore, the controlled alternate irrigation is a feasible irrigation method in Kaifeng. However, the quantity of controlled alternate furrow irrigation can be too low to enhance the yield of soybean and economic benefit.
