Abstract:: [Objective]The effects of applying two types of slow-release nitrogen fertilizers with different release modes on runoff nitrogen loss and silage maize growth in sloping land in central Yunnan was investigated to provide theoretical basis and support for soil and water conservation in sloping land in central Yunnan. [Methods] The runoff trough simulation experiment under natural rainfall conditions was studied, and ordinary urea was set under equal nitrogen conditions(CK), 40% instant Nortec ^21 with added nitrification inhibitor+60% ordinary urea(treatment I)and 40% coated slow-release nitrogen fertilizer polyglutamic acid synergistic 3 generations+60% ordinary urea(treatment Ⅱ)). [Results] The nitrogen loss of each treatment during the growth period showed a trend of increasing first and then decreasing, among which the nitrogen loss of CK was the highest, and the losses of total nitrogen decreased by 29.95% and 16.77% in treatments I and Ⅱ, respectively. Nitrogen decreased by 14.55% and 6.53%, respectively, and ammonium nitrogen decreased by 16.08% and 8.24%, respectively. Urea combined with slow-release nitrogen fertilizer could effectively increase soil total nitrogen and ammonium nitrogen contents and reduce nitrate nitrogen content. Compared with CK, treatments I and Ⅱ increased the soil total nitrogen contents by 3.25% and 0.87%, and the ammonium nitrogen content increased significantly by 30.57% and 25.70%, respectively; compared with CK, the nitrate nitrogen content of treatments I and Ⅱ decreased up 22.49% and 16.61%, respectively. [Conclusion] There is no significant difference in the yield of silage maize among the three treatments, but the application of slow-release fertilizer can reduce the runoff nutrient loss of slope farmland while ensuring soil fertility and meeting the normal growth requirements of silage maize Nortec ^21 works better.
