摘  要：
在水稻秸秆全量还田条件下,研究不同化肥用量对土壤养分及后季莴苣产量的影响,结果表明:稻秆还田处理与单施100%化肥处理相比,土壤碱解氮、有效磷含量平均增幅分别为5.04%、6.32%;土壤速效钾含量平均增幅19.35%,差异达显著水平。稻秆还田、减量施肥有利于提高莴苣株高、增加茎直径,显著提高莴苣产量;NP肥各减10%,K肥减30%、40%与单施100%化肥处理的莴苣产量相当。

摘  要：
Effects of different fertilizer amounts on soil nutrients and the yield of lettuce were studied under the condition of total returning of rice straw to paddy field.Results showed that,comparing with the single applying of 100% fertilizer,under,the average increasing ranges of soil alkaline hydrolysis N,available P in the treatment of total returning of rice straw were 5.04% and 6.32% respectively,and the average increasing range of available potassium was 19.35%,reached significant difference level.In addition,the composition treatments of rice straw returning and reducing fertilizer application could improve the plant height of lettuce,increase the stem diameter and enhance the yield obviously.Besides,there were no significant differences among the treatments of reducing N,P and K by 10%,10% and 30%- 40% respectively.
