摘  要:
为评价腐殖酸施用对香蕉土壤理化性状及抗逆酶活性的影响,分析了风化煤、 褐煤、 泥炭来源腐殖酸在4.5和3.6 t/hm2施用量水平下其香蕉园土壤理化性状及抗逆酶活性的差异,从而为香蕉园腐殖酸的合理施用及解决香蕉园连作障碍提供理论依据.结果表明,腐殖酸对土壤pH影响因品种和施肥量而异;3种来源腐殖酸均提升了土壤有机质、 速效磷含量和过氧化酶活性,且有机质和速效磷含量提升幅度随施用量增大而增大,而过氧化酶活性的提升则在HHA和NHA中随施用量提升而降低;FHA提升了土壤速效氮、 速效钾含量和过氧化氢酶活性,而HHA和NHA则相反.因此,在香蕉园中合理施用腐殖酸可有效预防连作障碍的发生.

摘  要:
In order to evaluating the influence of utilizing humic acid on soil physic-chemical properties and entienzyme activities,supplying the basis of reasonable humic acid usages and solving continuous cropping obstacles in banana plantation, the differences of soil physic-chemical properties and entienzyme activities under utilizing three derived humic acids in two usages of 4.5 and 3.6 t/hm~2 were analyzed. The results indicated different derived humic acids and doses differently affected soil p H, increasing contents and ranges of soil organic matter(OM)and available phosphorus(AP)accompanying increasing dosages of humic acid but increasing ranges of activities of peroxidase(POD) in treatment of HHA and NHA was inversing changed as OM and AP. FHA increased soil available nitrogen(AN), available potassium(AK) and activities of catalase(CAT), but changing inversely in treatment of HHA and NHA, so reasonable utilizing humic acid may efficiently prevent continuous cropping obstacles in banana plantation.
