The effect of soil ameliorative measures on water retention of aeolian sandy soil and the maize growth in Keerqin

The research was to explore the amount( 0,150,300,600 t hm- 2) of clay and its applied methods( surface application and subsoil application) in the aeolian sandy soil improvement. The effect of aeolian sandy soil measures on water retention and maize growth was studied through field plot test. The results showed that compared with control,the aeolian sandy soilu0027s water retention and the yield of maize was improved significantly at level of C3( 600 t hm- 2). Meanwhile,the leaf SPAD values and cushion height of maize increased significantly at level of C1( 150 t hm- 2). The effect of subsoil application was better when applying a low amount of clay.
