硝化抑制剂对苹果园酸性土壤尿素氨挥发的影响
Effect of Nitrification Inhibitor on Ammonia Volatilization in Acid Soil of Apple Orchard
摘要
Abstract
The field experiment was conducted to investigate the effects of dicyandiamide (DCD) and combined application of dicyandiamide and sulphur ( DCD + S) on ammonia volatilization in apple orchard acid soil by the venting method. The results showed that within 40 days after fertilization, the NH4+ - N eontent in soil of N+DCD and N + DCD + S treatments were higher than that of the single nitrogen (N) treatment, among them, that of N + DCD treatment was very significantly (P ＜0. 01 ) higher than that of N treatment within 6 ～ 20 days after fertilization, while that of N + DCD + S treatment was still very significantly ( P ＜0. 01 ) higher until 30 days after fertilization. The NO3- - B content in soil of the two nitrification inhibitor treatments obviously decreased by 18.72％ ～58.91％ compared with that of N treatment. The peak value of ammonia volatilization rate was the largest under N treatment, but its duration was the shortest. The duration of N+ DCD treatment was 19 days and that of N + DCD + S treatment was the longest, which was 17 and 7 days longer than that of N treatment and N + DCD treatment respectively. The gross of ammonia volatilization with nitrification inhibitor was significantly ( P ＜ 0. 05 ) higher than that of N treatment, but the ratio of gross rate of ammonia volatilization to N application rate was lower in all treatments.关键词
