| Abstract: |
| With field and pot experiments, a research was carried out on the effect of different soil conditioners (sulfur, PAM, organic fert
ilizer) on water and other characteristics of alkali saline soil in Niaxia. The results were shown as the followings: (1) All of four soil conditioners decreased soil bulk density efficiency, and the improvement of soil physical structure in combination with water use promoted alkali soil commonly; (2) The best amount of sulfur was between 675～900 kg/hm2; (3) Among four soil conditioners, PAM showed the best effect. |
