为了探讨非石灰性潮土长期施肥对小麦-玉米氮素利用及产量品质的影响，基于连续进行36年的长期定位施肥试验，利用15 N 示踪法研究了长期施有机肥及其配施氮肥对小麦-玉米氮素吸收利用及产量品质的影响。结果表明：长期施用低量有机肥（M1）氮素利用率最高为53．15％，其次为低有机肥配施低氮（M1 N 1）处理51．52％，分别比对照（CK）增加了24．33％，20．51％；长期施用高量有机肥配施高量氮肥（M2 N 2）处理，氮素残留率最高为40．07％，其次为高量有机肥配施低量氮肥（M2 N 1）为37．07％，分别比 CK 增加了42．5％，31．83％；单施低量有机肥（M1）处理的氮素损失率最低为10．84％，比 CK 减少了69．56％；施用高量有机肥配施高量氮肥（M2 N 2）小麦-玉米蛋白质含量最高，分别为15．76％，10．88％，比 CK 增加了14．29％，10．52％；施用高量有机肥配施高量氮肥（M2 N 2）小麦-玉米产量最高，分别比 CK 增加了500％，428．44％。

Based on 36 years long-term locating fertilization,the research using the 1 5 N tracer tests,studied the effects of long-term application of organic fertilizers on nitrogen absorption and utilization of wheat-maize.The re-sults showed that under long-term application of organic fertilizer treatment,the nitrogen efficiency was the highest with 53.1 5%,and secondly,by the lower organic fertilizer with lower N fertilizer treatment with 51 .52%,respec-tively increased by 24.33% and 20.51 % more than CK.Under long-term single organic fertilizer treatment,the re-sidual N was the highest accounting for 40.07%,and secondly,by the high organic fertilizer with lower N fertilizer treatment with 37.07%,respectively increased by 42.5% and 31 .83% more than CK.Under long-term application of organic fertilizer treatment,the nitrogen loss rates was the lowest with 1 0.84%,reduced 69.56% more than CK. Under long-term single organic fertilizer treatment,the protein content was highest of wheat-maize,1 5.76% and 1 0.88%,respectively increased by 1 4.29% and 1 0.52% more than CK.Under long-term single organic fertilizer treatment,the yield of wheat and maize is the highest respectively increased by 500% and 428.44% more than CK.
