不同氮肥施用方式及硝化抑制剂对小豆生长发育及氮素利用的影响
Effects of Different N Fertilizer Application Patterns and Nitrification Inhibitor on Growth and N Utilization of Adzuki Beans
摘要
Abstract
In order to investigate the application method of nitrogen in the process of planting adzuki bean, field experiments were conducted to study the effects of N fertilizer application patterns and nitrification inhibitor( NI) on growth and N utilization of adzuki beans. The results showed that the dry and fresh weight of plant,N accumulation and yield of adzuki beans treated with topdressing fertilization increased by 2. 7%,3. 7%,5. 6%,1. 9% compared with those of the base-fertilizer treatment respectively. And the difference of fresh weight, yield and N accumulation were significant. The apparent utilization efficiency, agronomic efficiency, physiological efficiency, yield contribution rate increased by 7. 4%, 23. 6%,15. 6% and 17. 2% respectively. Compared to the treatment without NI,the combination of NI with urea as base fertilizer could increase the plant fresh and dry weight,yield and accumulation of N by 2. 8%,10. 1%,6. 8% and 6. 9% significantly. The apparent utilization efficiency,agronomic efficiency,physiological efficiency, yield contribution rate increased by 26. 6%, 28. 5%, 1. 9% and 20. 1%respectively( except the fresh weight) . But no obvious difference was observed between the two treatments of topdressing N fertilizer with NI and without NI. Therefore,the topdressing N fertilizer was recommended under the condition without NI,and the base fertilization was recommended under the condition with NI.关键词
