[目的]以沼渣农田安全利用为目标,确立宁夏引黄灌区以沼渣为主的水稻配方肥最佳配方.[方法]采用随机区组试验,对相关指标进行室内测定.[结果]相对常规施肥,3个配方肥处理穗粒数、产量均有不同程度提高,但对千粒重、SPAD值基本无影响.[结论]综合考虑经济效益和生态安全,以水稻配方肥2为当地以沼渣为主的水稻配方肥的最佳配方.%[Objective] The research aimed to use biogas residue in safe and establish the best formula of biogas residue on rice in Yellow River irrigation areas in Ningxia. [Method] Randomized trial was done,and related index was detected . [Result] The grain number per spike and rice yield of three kinds of formula fertilizer increased while 1 000-grain weight and SPAD value kept the same with CK. [ Conclusion ] Combining with economic benefit and ecological safety, formula fertilizer 2 of biogas residue on rice was the best.
