Abstract
The pot experimental results showed that both available Zn content in soil and Zn concentration in plant of maize exhibited positive correlation with rate of applied Zn in salinized and non-salinized sierozem. In non-salinized sierozem, it had good function to all of Zn, N and P untrition of maize by the time of male-ear sprouting while rate of applied Zn was less than 37 mg/kg. Also the dry weight of plant was increased by 14. 8%-18. 5%, but the bad function was the activity's improvement of urease in soil. Meanwhile, it had good function to Zn and N nutrition of maize and decreasing the activity of urease when chemical Zn was applied at the rate of 75-240 mg/kg. And the dry weight of plant was increased by 11. 9%-10. 8%,but it had antagonistic function for maize to absorbing P nutrition. On the other hand, it was harmful to maize when the rate was increased to 720 mg/kg. The dry weight of plant and the activity of urease in soil were decreased by 8. 6% and 65. 4% respectively. It did seriously damage to maize when the rate was increased to 1440 mg/kg. The dry weight of plant and the activity of urease in soil were decreased by 62. 7% and 90. 3% respectively. In salinized sierozem, the optimum rate of applied Zn was 5-10 mg/kg. It would do harm to the shoot of maize while rate of applied Zn was more than 20 mg/kg.
