| Abstract: |
| This paper discussed the effect of inter-tillage on soil nutrients and corn yield by field experiment in dry-farming agricultural demonstration area of Fuxin in Liaoning Province. The results showed that, compared with traditional cultivation, deep loosening cultivation increased the content of soil organic in 0～30 cm soil layer and the content of total N, P and K in 0～20 cm soil layer, and it improved significantly the content of soil total N (P＜5%). It increased the content of alkaline hydrolytic nitrogen in 0～20
cm soil layer and the content of available potassium in 0～30 cm soil layer, and increased significantly the amount of available potassium in 0～10 cm soil layer P＜5%）. Deep loosening cultivation also increased significantly the content of available phosphorus in 10～30 cm layer（P＜5%）. Thus it increased t
he corn yield in this area, and the range of increase was 7.80%. |
