有机酸盐对土壤铝活性和杉木苗生长及矿质元素吸收的影响
|
摘要
为研究有机酸盐对土壤铝活性和杉木苗生长及矿质元素吸收的影响,采用一年生杉木苗为材料进行土壤盆栽试验,测定添加铝和4种有机酸盐后土壤酸度、土壤交换态铝含量、杉木苗生长指标、铝和矿质元素含量的变化。结果表明:加入有机酸盐土壤pH值升高,土壤交换态铝含量明显降低;有机酸盐对杉木苗高和地径生长均有抑制作用,铝在杉木苗的积累和叶中的分配呈增加趋势;有机酸盐对杉木矿质元素的吸收均有不同程度的影响,杉木苗镁、钾、磷、铜、锌、锰等元素的含量降低,而柠檬酸钠、草酸钠和酒石酸钠处理的杉木根和叶中钙和铁的含量增加。
In order to study the effect of organic acid salts on soil aluminum activity and the growth and mineral element absorption of Chinese fir seedlings,the annual Chinese fir seedlings were used as the materials of soil pot experiment to determine the changes of soil acidity,soil exchangeable aluminum content,the growth index and the contents of aluminum and mineral element of Chinese fir seedlings.The results showed that:When the organic acid salts were added,the pH value of soil increased and the content of soil exchangeable aluminum decreased significantly.The organic acid salts inhibited the height and basal diameter growth of Chinese fir seedlings,and the accumulation of aluminum in Chinese fir seedlings and the distribution of aluminum in the leaves showed an increasing trend.The organic acid salts had different effects on the absorption of mineral elements in Chinese fir.The content of magnesium,potassium,phosphorus,copper,zinc and manganese in Chinese fir seedlings decreased,while the content of calcium and iron in the roots and leaves of Chinese fir treated with sodium citrate,sodium oxalate and sodium tartrate increased.
