针对不同母质砖红壤中氨的挥发损失进行了研究。

Volatilization of ammonia from latosol soils with different matrixes was evaluated in the present study.

海南地处热带，地带性土壤有砖红壤、燥红土和山地赤红壤、山地黄壤等。

The zonal soils of Hainan province comprises with laterite, savanna soil, mountain lateritic red earth, mountain yellow earth, etc.

广泛分布于我国南方地区的砖红壤、红壤以及发育于红色粘土的水稻土，大多数属于高固磷土壤。

Most of the latosols, red soils, and paddy soils which derived from red earth in south China are high P-fixation soils.

通过土柱模拟氮、磷素养分淋溶试验，研究了不同施肥处理下砖红壤氮、磷素淋溶损失特点。

The leaching characteristics of nitrogen and phosphorus fertilizers and their effects on ground water quality were investigated through soil column nitrogen and phosphorus leaching experiments.
