| 摘 要： | 用密闭室强制通气装置对冬小麦不同基肥施用方式 (表施、深施和表施结合灌溉 )下的土壤氨挥发损失进行了研究 ,结果表明 :肥料在土壤中的位置对氨挥发损失的影响非常显著。表施处理明显促进氨的挥发 ,该处理试验期间白天累积氨挥发损失达 4 6 0 8%。而深施和表施结合灌溉处理都能有效地抑制氨挥发损失 ,2种施肥方式下试验期间白天累积氨挥发损失均未超过10 % ,表施处理的土壤氨挥发时期达 12d ,而深施和表施结合灌溉的氨挥发时期仅为 6d。 |

| Abstract: | Effect of different basal dressing application methods on soil ammonia volatilization was studied by using forced draft enclosure in winter wheat fields.The results indicated that fertilizer placement considerably influenced ammonia volatilization.Surface fertilizer application favored ammonia volatilization.The daytime cumulative volatilization loss amounted to 46 08%,while fertilizer incorporation and surface fertilizer application followed by heavy irrigation both markedly reduced ammonia volatilization,the daytime cumulative loss hardly greater than 10%.The duration of ammonia volatilization with surface application lasted for twelve days,while that with the other two application methods did not exceed six days. |
