- Moreover, Total protein content, Gliadin, Glutenin, and Glisdin to Glutenin ratio could arise with the increase of nitrogen fertilizer rate under the same SWC. 在同一土壤含水量下，总蛋白质、醇溶蛋白、麦谷蛋白含量及谷/醇比随着施氮量的增加而增加。
- The results showed that: the content of essential and total Aa. and etc. were increased significantly by applying N fertilizer in Tumochuan. 结果表明，在土默川地区，施氮肥后，必需氨基酸含量、酸性和碱性氨基酸含量及氨基酸总量极显著增加；
- Nugent says statistics on the fertility rate were also revealing. 认为生育率的统计书数也是很有启迪意义的。
- Because accumulation of photosynthate decreased, the increase in the N fertilizer made soluble sugar content in flag leaves reduce. 由于光合产物积累减少，增施氮肥使旗叶可溶性糖含量降低。
- Under the same nitrogen fertilizer rate, Both total protein and its component content decreased with the increase of SWC, meanwhile, Glisdin to Glutenin ratio was reduced. 在同一施氮量条件下，总蛋白质及各组分均随着土壤含水量的增加而降低，同时谷/醇比也降低。
- N fertilization induced a decrease of the infection rate, and the decrement varied with soil depth and season. 在不同季节和土层之间，施N肥导致菌根真菌侵染率下降。
- For example, farmers must make choices about managing N in legume production systems.These choices are complicated by the negative interaction between N fertilizer and BNF. 例如农户在豆类作物的氮管理上做出选择，由于氮肥和生物固氮之间的负相关而使选择变得复杂。
- N fertilizer application in wheat significantly increased total N, ammonium N and nitrate-N contents in paddy field, resulting in high indigenous N supply of soil (INS). 结果表明，麦季氮肥的施用明显提高了稻季土壤全氮、铵态氮和硝态氮的含量，造成土壤背景氮偏高。
- The results showed that the model of n fertilizer for Hard Wheat, higher in jointing than in seedtime and spike-time, was beneficial for high yield as well as quality. 研究结果表明，氮肥运筹以“前轻中重后补充”模式的产量品质俱佳；
