【 摘 要 】

In the process of land consolidation in the hilly regions, the water shortage is the main factor that restricts the Agricultural development in the hilly regions, and the fly ash and organic fertilizers are often used as the main field materials to improve the quality of soil. In order to investigate effects of fly ash and organic fertilizers on water use efficiency, related experiments were carried out at Fuping Pilot-base. The results showed as follows: (1) Different field materials had significant effect on oil temperature, with the values as TFC (fly ash and organic fertilizers) > TC (fly ash) > TF (organic fertilizers) > T0(control). (2) Different experimental treatments significantly affected crop yield and water use efficiency. The variation order between crop yield and water use efficiency among different treatments was TFC > TF > TC > T0. After considering the increase of soil temperature, yield and water use efficiency, fly ash and organic fertilizers should be compound use in the process of land consolidation in the Hilly Regions, which will greatly contribute to the yield and water use efficiency.
