摘要:: 以复配调理剂（50%生物炭+25%牡蛎壳粉+25%鸟粪石）为试验材料，在土壤酸化茶园进行田间试验，探究复配调理剂对土壤和茶叶品质的改良效果。设置CK组和T1～T3处理组，分别施加土壤调理剂0，1 500，3 000，4 500 kg/hm2进行试验。结果表明：与对照组相比，施用调理剂可提高土壤pH值和有机质、有效磷、速效钾的含量，分别提高了0.68~1.55，26.80~37.00 g/kg，22.82~39.18 mg/kg，86.23~108.04 mg/kg。同时，施加调理剂后，茶叶水浸出物和游离氨基酸含量增加，茶多酚含量降低，酚氨比下降，Cd、Cr、As和Pb含量在残留限量规定范围内。可见，施加复配调理剂可增加土壤肥力，提高茶叶的品质。

Abstract:: By using a composite conditioner(50% biochar+25% oyster shell powder+25% struvite) as the testing material,a field experiment was carried out to improve the soil and tea quality in the acidic tea gardens.Four groups CK and T1-T3 were set,including 0,1 500,3 000,4 500 kg/hm2,respectively.The results showed that the application of composite conditioner enhanced the soil pH value,organic matter,available phosphorus and potassium content compared with the control group,with increased values of 0.68-1.55,26.80-37.00 g/kg,22.82-39.18 mg/kg and 86.23-108.04 mg/kg,respectively.Meanwhile,after applying the composite conditioner,the content of tea water extract and free amino acids increased,together with the decrease of polyphenols and the phenol-ammonia ratio.Moreover,heavy metal contents of tea such as Cd,Cr,As and Pb were within the limits of residues.Therefore,the application of composite conditioners can improve soil fertility and tea quality.
