氮平衡

However, in the simulation, we found that the equilibrium between growing radicals and nitroxyl radicals was a CPU-intensive and time-consuming process, therefore, a hybrid algorithm with an analytical expression for the exchange equilibrium and with a biased sampling technique for those elementary reactions of small probabilities was used to improve the stochastic algorithm.

对三七GAP基地的土壤质地、供肥特性和土壤肥力进行了调查和分析，结果表明，三七GAP基地土壤以壤质粘土为主，偏酸性，土壤肥力水平较高，但各养分因子分布不平衡，氮、磷元素基本满足三七生长的需求，而钾元素普遍不足，在栽培管理上，应根据三七的生长特点、不同生长期及具体的种植片区对养分的要求制定施肥方案，并注意多施钾肥。

在内源氨基酸的测定方法中，以传统方法(无氮日粮法、回归外延法和完全可消化蛋白源或静脉灌注平衡氨基酸法)最为常用，但存在种种缺陷。

Within a short time span of just over 40 years China has developed from an insignificant to the world's largest and still fastest growing producer and user of chemical nitrogen fertilizer. Unfortunately China is now also the country with the most unbalanced nutrient ratio. If continued into the future, the grave nutrient imbalance that prevails at present threatens the fertility of China's soils that has been maintained so well over the centuries, thereby also threatening, sustainable agriculture.

仅40多年时间里中国就从世界上微不足道的氮肥使用国发展成为最大的、而且增长速度最快的氮肥生产和使用国，令人遗憾的是中国是世界氮、磷、钾使用最不平衡的国家，如果任凭这种趋势继续下去，将势必对数千年来我们祖先一直维持良好的地力造成威胁，由此也对农业持续发展带来威胁。

The average level of the soil available potassium was 119.96 mg/kg, which decreased 18.94 mg/kg and 1.05 mg/kg one year averagely. But the decreasing trend alleviated in recent years. There were 39.5 kg/hm^2 nitrogen and 30.9 kg/hm^2 phosphorus (P2O5) more than needed averagely, and 150.0 kg/hm^2 potassium (K2O) in deficiency. Though the fertilizer application was high and the rate of fertilizer was 647.96 kg/hm^2 in nutrient, the ratio of organic to inorganic was still unreasonable. The ratio of the chemical fertilizer nitrogen phosphorus (P2O5) and potassium (K2O) was 1:0.42:0.14. The nitrogen application was enough and even higher than that was needed. The phosphorus was proper elementarily and potassium was in deficiency. The yield of wheat which was the main crop increased slightly and that of other autumn harvest crops was stable.

土壤速效钾7年平均值119.96 mg/kg，比第二次土壤普查时下降了18.94 mg/kg，平均每年以1.05 mg/kg的速度下降，但近年来下降趋势变缓；养分平衡中氮素平均盈余39.5 kg/hm^2，磷素(P2O5)盈余30.9 kg/hm^2，钾素(K2O)亏缺150.0 kg/hm2；全省施肥水平较高，每公顷总施肥量折纯养分647.96 kg，但有机无机比仍不合理，化肥氮、磷、钾投入比例1：0.42：0.17，氮肥充足，部分地区用量偏高，磷肥基本合理，钾肥不足；主要农作物小麦产量略有上升，其它主要秋收作物产量基本稳定。
