摘要
通过田间小区试验的方法,研究了粘土施加量(0、150、300、600t hm-2)及施用方式(表施、底施)对风沙土保水性及玉米生长状况的影响。结果表明,与对照组相比,在施用方式一致时,粘土施加量在C3(600t hm-2)水平时可以明显提高沙土保水性及玉米的产量,并且施加量在C1(150t hm-2)水平时可以显著地提高玉米叶片的SPAD值以及促进叶枕株高的生长;在粘土施用量(<150t hm-2)较少时,底施的效果更好。
The research was to explore the amount（0, 150, 300, 600t 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 eompared with control, the aeolian sandy soil＇ s water retention and the yield of maize was improved significantly at level of C3 （600t hm-2）. Meanwhile, the leaf SPAD values and cushion height of maize increased significantly at level of C1 （ 150t hm -2 ）. The effect of subsoil application was better when applying a low amount of clay.
