| Abstract: | The purpose of this paper is to study of applied effect on the new cultivate irrigation area as soils improvement agent. According to the experiment for soil restoration in the years, the results showed that all yield of Wheat, corn, oil-use Sunflower, Pease and Benne increased on soil of applied improvement agent. Increased achievement of output has marked difference (p<0.001) , augment extent between 12.83%~47.92%. All comparative crops economic character have been mended respectively, especially, spike length of grain and thousand-grain weight improved effect( p < 0.05) Soil physical and chemical properties also have been meliorated obviously. |
