富铝化

相关性分析表明，红土化过程中，Au、As的富集与脱硅富铝化程度关系不大，而与铁的富集有明显的关系；

Results of correlation analysis showed that during laterization , the enrichment of Au and As has little bearing on desilicification and Al enrichment , but has a great bearing on Fe enrichment .

铁氧化物含量明显高于上陆壳平均值；SiO2与（Fe2O3＋Al2O3）线性负相关关系明显，显示红土化、强盐基淋失和脱硅富铝化特征。

Iron oxide is significantly higher than UCC ; there is a significantly negative linear correlation between SiO2 and ( Fe2O3 + Al2O3 ), which indicates strong base leaching and desilicification-allitization features .

综述了近年来网纹红土研究的事实成果，结果表明：网纹红土的强酸、富铝化特征明显；

The studies of vermiculated red soil in recent years are summarized , The results show that the strong acid and laterized characteristics of vermiculated red soil are obvious ;

土壤有机质含量提高，富铝化作用增强，而其它的土壤养分，不同树种之间差异较大，但从总体看，阔叶林在改良土壤理化性质方面优于针叶纯林。

For other soil nutrients , there existed significant difference among tree species , but overall , the broadleaved forest was better than coniferous forest in improving soil physical and chemical properties .

第四纪红粘土发育的低丘红壤茶园，由于土壤不断富铝化，酸度大，增强了钾的淋失，全钾含量趋向贫化。

The accumulation of aluminum and the serious acidification in the soil during its development from qua-ternary red clay stimulated the potassium leaching and decreased the total potassium content in the soil .

南方土壤由于长期脱硅富铝化过程，土壤中全硅和有效硅的含量均较低，研究硅对提高中国花生的产量对和品质有重要意义。

The content of total and available silicon in soil because of the forming process in south china are lower than that need to plant , study on silicon yield effect of peanut has great significance .

本文在该县土壤普查和室内土壤分析研究的基础上，认为该县大部分丘陵山地土壤应属于黄红壤&富铝化土壤中红壤土类的一个亚类。

On the basis of soil survey and study in laboratory of the representative soil profiles we found that most of the soils on hilly land should be classified as the Yellow-Red Earth , a subgroup of the Red Earth under alli-tic soil order .

铝毒是酸性土壤中植物生长受限制的主要因素，我国是拥有大面积以红壤为主的酸性富铝化土壤的农业大国，对植物耐铝毒机制的研究就显得非常重要。

Aluminum ( Al ) toxicity is one of the major factors limiting the growth of plants in acidic soils . China is an agricultural country with lots of red soils which contain Al . It is very important to explore the mechanism of plant to tolerance Al toxicity .
