摘  要：
针对雷竹林有机氯农药六六六(HCH)残留普遍存在的现实问题,开展了雷竹林土壤HCH原位生物修复及修复菌剂(BHC-A)对雷竹新陈代谢及生理活性、竹林土壤养分活化影响的研究。结果表明,BHC-A原位降解HCH效果显著,降解率高达85.25%;BHC-A使用后,处理A、B较对照雷竹叶片叶绿素SPAD值分别提高12.82、11.36,根系活力分别提高了37.77%、24.25%,处理间差异显著,说明BHC-A可以提高雷竹新陈代谢及生理活性;BHC-A生物修复过程中,与对照相比,处理A、B土壤pH值分别下降了0.40、0.14个单位,土壤水解氮分别提高了80.33、62.67 mg.kg-1,差异达显著水平;处理A土壤有效磷、速效钾较处理B和对照分别提高了33.02、36.98 mg.kg-1和27.91、29.33 mg.kg-1,差异达显著水平;不同处理间土壤有机质及全效养分变化不明显,即BHC-A可以促进土壤养分释放,提高养分生物有效性。

摘  要：
The effect of bioremediation agent on metabolic and physiological activity of Phyllostachys praecox and soil chemical property was studied in this paper focusing on the approaching the residue of organochlorine pesticide in soils of bamboo plantation forested,as well its bioredimation by BCH-A.After applying bioremedation agent of BHC-A,it was found that HCH concentration in soils decreased significant-ly,and reduction rate reached above 85%.The SPAD value in leaf of P.praecox in treatment A and B increased by 37.77% and 24.25%,and root activity increased by 37.77% and 24.25% respectively.It also was found that SPAD value in leaf and root activity among treatments A,B and CK had very significant difference,which indicated that metabolic and physiological activity of P.praecox was enhanced greatly.After BCH-A was applied,soil pH value of treatment A,B decreased by 0.4 and 0.14,soil available nitrogen content increased to 80.33 mg.kg-1 and 62.67 mg.kg-1,respectively.While it was found soil pH value and available nitrogen content were significant different.Moreover the re-sults shown that soil available phosphorus and potassium in treatment A was higher 33.02,29.33 mg.kg-1 than that of treatment B,and that of treatment A was higher 27.91,36.98 mg.kg-1 than that of CK,respectively.However it discovered that applying BHC-A had little effect on soil total nutrition and organic matter content,which indicated that BHC-A might stimulate the release of soil nutrients and enhance the bioavailability of soil nutrients.
