土壤酸化

此外，土壤酸化与有效P之间的关系密切。

And there was a close relation between soil acidification and soil available phosphorus ( AP ) content .

对大气干湿沉降和化肥的研究表明，土壤酸化速度明显，pH值年均降低0.02。

The soil acidification is obviously rapid , with an annual decrease of 0.02 , due to both atmospheric deposition and fertilization .

由于多年来N肥持续大量施用以及不合理的农业耕种、施肥制度和管理措施，导致我国北方土壤酸化日趋严重。

Due to long-term excessive N fertilizer application , unreasonable farming system and management measures , the soil acidification in north China was getting more severely .

土壤酸化还将导致土壤中重金属元素（Fe、Mn、Cu、Zn、Pb和Al）的活化度增加，研究还表明。

Soil acidification will cause increasing heavy metal ( Fe , Mn , Cu , Pb Zn , and Al ) mobility in soil as well .

沸石能减轻土壤酸化程度，提高土壤pH值，降低EXC-Mn。

Zeolite could release soil acidity , increase soil pH and decrease exchangeable Mn .

N、P、K肥三种肥料的均衡施用对土壤酸化的影响较小，施猪粪及秸杆还田也能对土壤酸化进行缓解。

The balance utility of N , P , K fertilizer can cause little influence on soil acidification , and the use of manure and the returning of straw to field can relieve the soil acidification .

从生物地球化学循环的观点出发，研究了N循环的人为干扰与土壤酸化的关系，并探讨了N循环扰动下导致土壤酸化的机理。

The relation between soil acidification and nitrogen cycle disturbed by man made factors was studied from the viewpoint of biogeochemical cycle , and the mechanism of soil acidification induced by disturbed nitrogen cycle was probed .

土壤酸化是土壤退化的一个重要方面。土壤酸化伴随着土壤pH下降、盐基和养分损失、铝和重金属活性提高，从而导致森林衰退和农作物减产。

Soil acidification is one of the important process of soil degeneration , which lead to decrease of pH , lose of base and nutrient , enhancement of aluminum and heavy metals activation , consequently resulting of deforestations and desease of crops ' yield .

土壤酸化还造成K、Na、Ca、Mg等盐基离子大量淋失，有益元素有效态含量也急剧减少，土壤肥力下降，养分贫瘠，土壤质量下降。

Moreover , soil acidification causes big losses of electropositive ions such as K , Na , Ca , Mg by eluviation , and rapidly decreases the available beneficial elements , therefore resulting in a reduction in soil fertility , nutrient and quality .

因此在Cd污染菜地中，应选用以DCP、TCP为主要成分的磷酸二钙和钙镁磷肥，或尽量控制施用可促进土壤酸化的磷肥用量，如磷酸一铵、磷酸二铵和过磷酸钙。

Therefore in Cd contaminated vegetable field soils , dicalcium phosphate and calcium magnesium phosphate fertilizers mainly containing DCP or TCP should be preferably selected , while the overdose of DAP , MAP and SSP should be avoided .
