| Abstract: |
| An experiment of leaching slightly saline-sodic soil with mildly saline water was conducted for analysis of change in corn growth character, such as plant height, leaf area index and root, etc. There were four treatments: CK; supplementary irrigation; low-rate leaching; and high-rate leaching．Results indicate that the average plant height in Treatment 3 increased by 13% compared to that in CK. Leaf area index in both Treatment 4 and 3 increased significantly compared to that in CK. Corn yield in Treatment 4, 3 and 2 increased respectively by 68.69%, 62.25% and 8.41% compared to that in CK. It is obvious that corn growth character and yield in leaching treatments was improved significantly, and water condition was an important effect. It is hence concluded that suitable prefer ential volume of leaching in slightly saline-sodic soil in western Jilin Province is 150 mm, providing sufficient condition for local corn growing healthily. |
