- N application rate 施氮量
- The N application of later-date-emphasized increased amylose and amylopectin accumulating rate. 侧重后期施氮处理有利于提高直、支链淀粉积累速率。
- The results showed that the N application of later-date-emphasized could promote grain filling rate, increase grain weight and amylopectin content. 结果表明，侧重后期施氮可以促进籽粒灌浆、增加粒重，同时还可适当提高稻米支链淀粉含量。
- Incorporating Chinese Milk Vetch into soil can reduce the chemical N fertilizer application rate by 44%, and also diminish the environmental risk of N runoff. 利用豆科紫云英轮作还田,可降低44%25的无机N肥用量,溶解性N浓度显著降低,是减小稻季N肥流失环境风险的有效途径。

- Results showed that increasing nitrogen application rate increased total N uptake,but decreased the percentage of nitrogen exported(PNE)from vegetative organs,nitrogen harvest index(NHI)and nitrogen efficiency for grain production(NEGP). 结果表明 ,施氮量增加 ,水稻吸氮量增多 ,但营养器官的氮转运率、氮收获指数和产谷效率显著下降 ;
- Furthermore, N and P fertilizer application rate could be decreased accordingly to optimize fertilizer management when contributions from eutrophied irrigation water were taken into consideration. 在利用当地富营养化河水进行稻田土壤灌溉时可适量减少肥料施用量、优化氮磷肥料管理。
- N application rates 施氮量
- Calibrate pesticide sprayers in order to assure that the desired application rate is being applied. 校准农药喷雾器的目的，是为了保证按所需的量予以喷洒。
- Besides the N application, another possible factor which might contribute to the difference was the practice used in controlling of late tillering. 除氮肥用量外，另一个造成差别的可能影响因素是控制迟到的分蘖措施。
- VAT is also payable by you at the applicable rate as shown on your invoice. 大桶以出现在你的发票上的适用的率由你也是应付的。
- Brassica rapa was selected as research object to study the effect of fertilizer application rate in high altitude zone of Qinghai Province. 在青海省高海拔农业区,以当地主要种植的白菜型油菜作为试验对象,进行增施不同用量钾肥的大田试验,研究其对油菜产量的影响及肥料效应。
- Silicon application promote N uptake by plant, while increasing N application could increase Si uptake by plant but Si addition probably inhibit K uptake. 施硅促进植株吸氮，而提高吸氮量可以提高植株吸硅量，但施硅可能抑制吸钾。
