The results showed that the regulations of N and P were kernel leaf stem and sheath under the urea and many elements long-acting ammonium bicarbonate,whereas the regulation of K was stem and sheath leaf kernel. The utilization efficiency and harvest index of N,P and K were similar and did not have the significant difference between urea and ammonium bicarbonate. The group of wheat was 6. 68 × 107 and 6. 41 × 107/ hm2 in the urea and ammonium bicarbonate treatment,respectively,which significantly increased compared with the control. Under the urea and ammonium bicarbonate treatment,the ear length and actual spikelet were 11. 9 %,11. 6 % and 10. 9 %,10. 6 % higher than that of control,and the thousand kernel weight,kernels per spike and yield were 13. 8 %,15. 2 %,15. 2 % and 14. 5 %,10. 0 %,14. 2 % higher than that of control,respectively. However,there were no significant differences between urea and ammonium bicarbonate. So the ammonium bicarbonate had high fertilizer effect,meanwhile it could reduce the N loss compared with the urea. All the results suggested that many elements long-acting ammonium bicarbonate could be used as a new type N fertilizer with the high effectiveness and low input,and it had the good prospect in agricultural production application.Read More
