1·Soils are most commonly deficient in nitrogen and phosphorus.
土壤最经常缺乏氮和磷。
2·Soil samples from these pens or corrals show ten times the concentration of phosphorus.
来自这些围栏或畜栏的土壤样本显示，磷的浓度是其10倍。
3·Carnivorous plants instead draw nitrogen, phosphorus, and other critical nutrients from their prey in order to build light-harvesting enzymes.
相反，食肉植物从它们的猎物那里吸收氮、磷和其他重要的营养物质，以制造聚光酶。
4·The phosphorus at the bottom of the ocean has to somehow make its way back to the surface, to complete the cycle, to begin the cycle all over again.
海底的磷必须找到某种方式回到表面，以完成这个循环，从而重新开始这个循环。
5·It can be washed out when it rains or it can be released to the atmosphere, whereas phosphorus combines with calcium and iron, and can be preserved in the soil for thousands of years.
它可以在下雨时被冲刷掉，也可以释放到大气中，而磷与钙和铁结合，可以在土壤中保存数千年。
1·Typically, older leaves are affected first as the phosphorus is mobilized to young growing tissue.
通常，当磷元素向新生组织转移时，较老的叶片首先受到了影响。
2·More immediately, fertilizers used in farming have injected vast amounts of nitrogen and phosphorus into regional environments.
比较直观的是，用于耕地的化肥输入大量的氮元素和磷元素到环境当中。
3·P is the only stable isotope of phosphorus.
是磷元素唯一稳定的同位素。
4·The segregation of phosphorus on steel grain boundaries can be divided into two categories, which are, equilibrium segregation and non-equilibrium segregation.
磷元素在钢中的晶界偏聚可以分为两类，即平衡偏聚和非平衡偏聚。
5·Phosphorus (p) is one of the main limiting nutrients to the plant growth and net primary productivity (NPP) in terrestrial ecosystem.
磷元素是陆地植物生长和生态系统净初级生产力的主要限制因子之一。
1·For the future we should attach importance to organic fertilizer on farmland, control the dosage of nitrogen fertilizer, increase the proportion of phosphorus and add kalium fertilizer properly.
今后农田施肥，应当重视施用有机肥，控制氮素化肥用量，增加磷素养分比例，适当补施钾肥。
2·The phosphorus transport and removal efficiency were analyzed on the basis of bank buffer strips model test in laboratory.
通过模拟试验分析改进后堤岸缓冲带对磷素运移规律及其去除效应的影响。
3·However, as the water stress increases, the phosphorus accumulation of root decreases at vegetative stage and reproductive stage.
在营养和生殖生长阶段旱稻茎含磷量和磷素累积量随水分胁迫程度加深而降低。
4·The results showed that straw application increased crop yield, soil organic carbon accumulation, soil total nitrogen and phosphorus content as well as phosphorus activation.
结果表明，秸秆还田提高了作物产量，增加了土壤有机碳积累和土壤氮磷含量，且能活化土壤磷素。
5·The releasing characteristic of soil phosphorus can be exactly depicted by parabolic diffusion equation.
抛物线扩散公式能很好地拟和土壤磷素释放特征。
