- Nitrogen accumulation by non-nodulated soybean (Table 3) measures the amount of mineral N available in the soil. 不结瘤大豆积累的氮素(表3)可以测算出土壤中有效矿质氮的总量。
- The results showed that leaf nitrogen accumulation was exponentially related to leaf SPAD values and linearly related to canopy spectral reflectance. 结果表明,小麦抽穗后叶片氮积累量也叶片SPAD值、冠层反射光谱分别呈显著的指数和线性相关;
- Effects of KNO3 spray on nitrate reductase activity (NRA) and nitrogen accumulation were studied in Pyrus pyrifolia cv. Niitaka seedlings grown in pots. 在盆栽条件下,研究了喷施KNO3对新高梨实生苗硝酸还原酶活性(NRA)和氮素积累的影响。
- 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。
- soil inorganic nitrogen accumulation 土壤无机氮累积
- nitrogen accumulation and translocation 氮积累和运转
- As to the nitrogenous accumulation of above-ground in the two years, T2 is the highest, and T3 is the lowest. 在2003年晚稻不同生长阶段,硝酸还原酶活性以早稻不施氮、晚稻施氮处理(T4)最高,以早晚两季均不施氮的处理(T3)最低。
