| Abstract: | In order to resolve the problems such as lack of water resource and low utilization effi ciency of nutrients in the arid area, the effect of humic acid water-retaining slow-released fertilizer on corn growth was studied. The results showed that the application of this fertilizer could play an obvious role in anti-drought and water retention. In addition, it could improve the utilization efficiency of nutrients, accelerate the cron growth, enhance the activity of corn root, and increase chlorophyll content. Ultimately, corn yield was raised. |
