Abstract:

To improve the fertility of saline-alkali soil and set up the best system of saline-alkali for fertilizing, the located text studied the effects of different fertilizers (chemical fertilizers, manure, organic-chemical compound fertilizer, organic fertilizer and bio-fertilizer) on the organic matter, total N, available N, total P, available P, pH and available K. The results showed that, all tested fertilizers improved the fertility, comparing the control, and manure increased organic matter, total N, available nitrogen, total P, available P, and available K at the times of 1.47, 1.3, 1.28, 2.97, 3.24, and 1.62, respectively. All tested fertilizers could reduce the pH. The organic fertilizer was effective relatively at the times of 0.95. The results showed that, organic matters had the best function to improve the aline-alkali soil.
