Determination of lime requirement in forest soil
森林土壤石灰施用量的测定
Laboratory culture experiment with the same treatments as pot experiment but without plant was carried out synchronously under constant temperature ( 25 ? ? ) and 20 % soil moisture . to study the influence of inhibitors on the dynamic process of transformation and variation of availability of cd in soil , laboratory cultured soil was sampled in certain interval during the 128 - day cultured period for the analysis of cd availability and speciation . in adsorption - desorption experiment , the tested soil had fistly been cultured under constant temperature ( 25 1 ) and 20 % soil moisture for two months after the treatment according to the designed plan , then isothermal adsorption - desorption experiment was proceeded when the reaction between inhibitor and soil tended to be stable
石灰施用量对植株吸收锅有显著影响，植株各部位锅含量k ）与石灰添加量… ，）的关系可以很好地用方程y叫（ ax斗bx化）描述，石灰对植株锅累积的调控存在一个最佳抑制效应剂量，低于或高于这一剂量均不能达到最佳抑制效果，但对于不同植株部位和不同污染水平，最佳抑制效应剂量不同；低用量下，单位石灰添加量对植株吸收锅的抑制作用比高用量时大，因此若综合考虑调控剂的施用成本及其对生物量的影响效应，则在本试验条件下以施用石灰0
