  1. 施蘑菇肥可增大土壤盐基饱和度,提高冬季草坪质量。

    Mushroom debris enhanced base saturate rate , and made a better quality of winter turf .

  2. 不论施用哪一种氮肥,土壤盐基饱和度都随着施氮量的增加而减小。

    No matter which sorts of nitrogenous fertilizer , the soil base saturation ( BS ) decreased with the increasing amount of nitrogenous fertilizer .

  3. 粘粒的矿物学鉴定和土壤盐基饱和度及腐殖质组分分析等,均证实了野外土壤勘察中对这些土类和亚类划分的确切性。

    Mineralogical study of clay fraction and analysis of humus fraction and base saturation confirmed the precision of the soil classification of these soils in our soil survey .

  4. 大多数土壤盐基饱和度50%,2个土壤剖面盐基饱和度30%,而且铝饱和度较高为60%~90%。

    Most of the soils studied are eutrophic with base saturation ( BS ) above 50 % , and two soil profiles have high aluminum saturation ( AS ) from 60 % to 90 % , with the BS lower than 30 % or even 20 % .

  5. 当外源镧浓度大于300mg/kg时,土壤盐基饱和度与有效阳离子交换量显著降低,而交换性酸和交换性铝显著增加。

    When the concentration of exogenous La 3 + was higher than 300 mg / kg , base saturation percentage ( BSP ) and effective cations exchange capacity ( ECEC ) decreased significantly , exchangeable acidity and exchangeable aluminum , however , increased significantly compared with the control .

  6. 土壤pH与盐基饱和度呈非线性正相关,且主要受占优势的交换性Ca2+制约。

    The soil pH is also significant positive correlation with Base Saturation , which is mainly restricted by Exchangeable Base Ca ~ ( 2 + ) .

  7. 结果表明,随模拟酸雨pH值下降,土壤pH值和盐基饱和度明显降低,而交换性酸度明显增加,污染土壤中交换性氢含量比未污染土壤高,而交换性铝含量比未污染土壤低。

    The results showed a decrease of pH and base saturation , and increase content of exchangeable acidity in both uncontaminated and contaminated red soil and yellow red soil within the pH decreasing of simulated acid rain , significantly .
