The utilization rate of N fertilizer of the former was significantly lower than that of the later, and the contribution of soil mineralizable N was relatively higher in the former, compared with the later.

前者对肥料氮的利用率较后者显著地低，且土壤矿化氮在所吸收的氮中的贡献率也相对较高。

Soil N mineralizable capability and effect of mineralized N with or without SON on soil N-supplying capacity was studied.

结果表明，供试土样起始可溶性有机氮平均为N 23.9 mg/kg，是起始提取态总氮的28.8%，土壤全氮的2.4%。

Aquatic crustaceans are typical ammonotelic animals. They excrete nitrogenous wastes in the form of ammonia. However, under high salinity, the hemolymph of Penaeus Monodon was found to contain a large quantity of urea. The aim of this thesis was to investigate the mechanism of how nitrogenous metabolites change under different salinities.

水生甲壳类是典型的排氨型动物，体内含氮废物以氮的型式代谢，但草虾於高盐环境下，其血淋巴中却产生大量的尿素，本论文研究的目的即在探讨含氮代谢物在环境盐度变化下的转换机制。
