基于江西进贤红壤性水稻土长期施肥定位试验,对不同施肥处理进行土壤肥力质量评价。结果表明:有机无机配施肥处理(NPKOM)的肥力质量等级为二级,其它施肥处理均为三级,其中对照和单施氮肥处理土壤肥力质量有明显降低的趋势。
Based on the long-term fertilization experiment of red paddy soil in Jinxian, Jiangxi, soil fertility evaluation was conducted on different fertilization treatments. The results showed that the fertility quality grade of NPKOM was Grade II, and the other fertilization treatments were Grade III. The fertility quality of NPKOM decreased obviously under the control and single application of N fertilizer.
