In 2006-2007, a field trial was conducted to study the effects of applying three kinds of organic-inorganic compound fertilizers [rapeseed cake compost plus inorganic fertilizers (RCC), pig manure compost plus inorganic fertilizers (PMC), and Chinese medicine residues plus inorganic fertilizers (CMC)] on the crop growth and nitrogen (N) use efficiency of rice-wheat rotation system in South Jiangsu. Grain yield of wheat and rice in the different fertilization treatments was significantly higher than the control (no fertilization). In treatments RCC, PMC and CMC, the wheat yield was 13.1%, 32.2% and 39.3% lower than that of the NPK compound fertilizer (CF, 6760 kg x hm(-2)), respectively, but the rice yield (8504-9449 kg x hm(-2)) was significantly higher than that (7919 kg x hm(-2)) of CF, with an increment of 7.4%-19.3%. In wheat season, the aboveground dry mass, N accumulation, and N use efficiency in treatments RCC, PMC, and CMC were lower than those of CF, but in rice season, these parameters were significantly higher than or as the same as CF. In sum, all the test three compound fertilizers had positive effects on the rice yield and its nitrogen use efficiency in the rice-wheat rotation system, being most significant for RCC.
2006 - 2007年，开展了一项田间试验，研究施用三种有机 - 无机复合肥[菜籽饼堆肥加无机肥（RCC）、猪粪堆肥加无机肥（PMC）和中药残渣加无机肥（CMC）]对苏南稻麦轮作系统作物生长及氮（N）利用效率的影响。不同施肥处理下小麦和水稻的籽粒产量均显著高于对照（不施肥）。在RCC、PMC和CMC处理中，小麦产量分别比NPK复合肥（CF，6760 kg·hm⁻²）低13.1%、32.2%和39.3%，但水稻产量（8504 - 9449 kg·hm⁻²）显著高于CF（7919 kg·hm⁻²），增幅为7.4% - 19.3%。在小麦季，RCC、PMC和CMC处理的地上部干质量、氮积累量和氮利用效率均低于CF，但在水稻季，这些参数显著高于CF或与CF相当。总之，所有三种试验复合肥对稻麦轮作系统中的水稻产量及其氮利用效率均有积极影响，其中RCC的影响最为显著。
