不同施肥方式对竹林土壤铜、锌、锰的影响

Effects of Different Fertilization Methods on Soil Copper,Zinc and Manganese of the Bamboo Forest

[目的]研究不同施肥方式对竹林土壤中铜、锌、锰含量的影响。[方法]设置施复合肥(F)、施有机肥(O)、有机肥复合肥混施(O+F)3个处理,以不施肥处理(CK)为对照进行比对。[结果]施肥处理会使土壤中有效锰的含量增加,有效锌含量降低;有效铜含量以F处理的最高,O+F处理最低。[结论]施肥处理有利于竹林土壤有机质、碱解氮、速效磷和速效钾的累积。施有机肥或有机肥复合肥混施会使有效锌、铜含量降低,但有助于土壤中有效锰的累积,能缓解土壤酸化问题。

[Objective] The research aimed to study the effects of different fertilization methods on the contents of copper,zinc and manganese in the soil of bamboo forest.[Method] Three treatments that were applying the compound fertilizer(F),applying the organic fertilizer(O) and applying the organic fertilizer and compound fertilizer(O +F)were set,and the non-fertilization treatment(CK) was used as the control.[Result] The fertilization treatment increased the content of available manganese in soil and decreased the content of available zinc.The available copper content was the highest in F treatment and the lowest in O +F treatment.[Conclusion] The fertilization treatment was beneficial to the accumulation of soil organic matter,alkali-hydrolyzable nitrogen,available phosphorus and available potassium in the bamboo forest.Application of organic fertilizer or mixed organic fertilizer and compound fertilizer would make the effective zinc and copper content decreased,but contribute to the accumulation of effective manganese in the soil,and it could alleviate the problem of soil acidification.
