Abstract
With summer maize as the experimental material,different water treatments were set up to study the effects of conventional furrow and wheat corn integration ridge tillage furrow on irrigation water quality and the summer maize yield.The results showed that:irrigation water efficiency under furrow irrigation with integration ridge tillage were higher than that under conventional furrow irrigation;Ea both decreased with the increase of soil moisture lower control limit,and Ea decreased more obviously under furrow irrigation with integration ridge tillage.Under two irrigation modes,irrigation uniformities were both higher,especially under conventional furrow irrigation.Under different furrow irrigation modes,the corn yield was improved significantly under furrow irrigation with integration ridge tillage and the average growth rate was 8.67%.Too low or too high moisture were both unfavourable to yield and its components.With suitable moisture lower control limit,the effects of water-saving and improving yield were more obvious under furrow irrigation with wheat corn integration ridge tillage.
