| Abstract: |
| Effect of different C/N manure on the content of soil NO-3 under different doses of N fertilizer was discussed.The results showed that there was no significant effect on soil NO-3 by applying the different manure mixed with low doses of nitrogen fertilizer.Soil NO-3 increased by applying the M1 accompanying with high doses of nitrogen fertilizer.But soil NO-3 decreased by applying the M2 and M3 mixed with high doses of nitrogen fertilizer.Soil NO-3 of N3M1 and N4M1 treatment increased by 11.6% and 14.4% respectively,compared with N3 and N4.Soil NO-3 of N3M2 and N3M3 treatment decreased by 15.9% and 37.9% respectively,compared with N3.There was no significant difference between the treatments of N4M2,N4M3 and N4 in effect on soil NO-3. |
