摘 要：以貴州安顺蚕种场茶园土壤为研究对象，探讨了土壤调理粉剂不同用量对茶园土壤营养元素、C/N、C/P及N/P化学计量比的影响，以期寻找有机高效栽培手段，为茶产业裂变式的发展提供重要的指导意义。结果表明：（1）4个不同处理的土壤pH值、有机质及全氮平均含量均表现为A处理>C处理>B处理>CK;碱解氮平均含量表现为C处理>A处理>B处理>CK;全磷平均含量表现为B处理>A处理>C处理>CK;速效磷平均含量表现为A处理>B处理>C处理>CK。（2）研究区域的土壤肥力除了CK的速效磷为丰富水平外，其余指标均达到极丰富水平。（3）A、B、C三种处理对改善土壤酸化及增加土壤肥力均有着很大的影响，但随着调理粉剂用量的增加，影响较小。（4）土壤C/N表现为CK>A处理>C处理>B处理，土壤C/P表现为C处理>CK>A处理>B处理;土壤N/P表现为C处理>B处理>A处理>CK。综合4种处理方式对土壤肥力及土壤养分供给能力，贵州安顺蚕种场茶园的土壤调理粉剂用量优先考虑A处理，即40 kg/667m2。

Abstract：Taking the soil of ecological tea garden in Anshun silkworm seed farm of Guizhou province as the research object，the effects of soil conditioning powder at different dosage on nutrient elements and stoichiometric ratios of C/N，C/P and N/P in tea garden soils were explored，so as to find organic and efficient cultivation methods，which should provide important guiding significance for the fission-type development of tea industry.The results showed that：（1） The pH，organic matter and total nitrogen content of soils in the four different treatments were treated as A treatment>C treatment>B treatment>CK;the average content of alkali-hydrolyzed nitrogen showed as C treatment>A treatment>B treatment >CK;the average content of total phosphorus was B treatment>A treatment>C treatment>CK;the average content of available phosphorus showed as A treatment>B treatment>C treatment>CK.（2） The soil fertility in the study area reached the extremely abundant level except for the available phosphorus of CK treatment，which was abundant.（3） The three treatments A，B and C have a great effect on improving soil acidification and increasing soil fertility，but the effect was relatively small with the increase of the amount of conditioning powder，（4） Soil C/N ratio performed CK>A treatment>C treatment>B treatment，while soil C/P ratio was C treatment>CK>A treatment>B treatment;results of soil N / P ration was C treatment>B treatment>A Process>CK.Based on the fertility and nutrient supply capacity of soils at four treatments，the amount of soil conditioning powder used in Guizhou AnShun silkworm seed farm tea garden is prior to A treatment.
