Experimental study on water movement of latosol under drip irrigation 滴灌条件下砖红壤水分运动试验研究
2.
This climate make latosol usually as acidic , low levels cation exchanges capacity and low lever base cations , high levels of exchange al , with a high potential for leaching of plant nutrients 这种气候条件使砖红壤成为强酸性土壤，阳离子交换量和盐基饱和度低，铝饱和度高，化肥通过淋溶损失过程就更为突出。

To increase the fertilizer utilization in the latosol , studying the fertilizer leaching and conversion characteristic , such as leaching velocity reaching amount , conversion path etc , seem to be extremely important . however , hitherto the study of fertilizer nutrient leaching characteristic are scanty , only some on the mineral nutrient derived from latosol 要提高化肥在砖红壤中的利用率，研究其淋溶及转化特征则显得极为重要，如淋失速度、淋失量、转化途径等，然而迄今为止，在砖红壤上这方面研究报道较少，且主要是针对砖红壤中矿化出来的营养元素，而缺乏对化肥在砖红壤上淋失特征的研究。
