- Total nitrogen accumulation amount of CMS lines was distinctly higher than their homotypic lines (P<0.05), with more nitrogen distributed to stalk and grain in CMS lines. CMS玉米氮素积累总量高于其同型可育系(P<0.;05)，成熟期氮素在茎秆和籽粒中分配较多；
- The results indicated that the rice model and nitrogen modules can predicted the actual rice growth and nitrogen accumulation and distribution dynamics in two rice varieties. 但总体来看，该模型不仅能较准确地模拟水稻生长动态，而且可以模拟水稻氮吸收和积累的行为动态。
- The relation of NRA (NRactivity) and nitrogen accumulation of leaves in each growth stage was studied on the two different protein content wheat varieties, Lumai 5 and Changle 5. 摘要以鲁麦5号和昌乐5号两种不同蛋白质含量小麦品种为材料，研究了各生育期叶片NRA与氮素积累的关系。
- Therefore, soil inorganic nitrogen accumulation was increased significantly by N application, but was significantly reduced by legume/cereal intercropping. 因此，施氮肥显著增加土壤无机氮的累积，而豆科/禾本科间作减少了土壤无机氮的残留。
- In the tiller stage, the nitrogen accumulation quantity of high nitrogen treatment was obviously higher than that of low nitrogen treatment, but it was reverce after the booting stage. 在同一施氮水平和施氮方式下，增施钾肥有利于提高生育后期对氮的吸收。
