    摘要:

    为探究西南地区茶园土壤养分特征及其影响因素,以文献计量法对西南地区4 省(区)茶园土壤进行研究,从整体和局部尺度分析了茶园土壤养分在不同空间、海拔、降水、土壤类型差异下的分布状况及特征。结果表明,西南茶区整体表现为有机质、全氮、碱解氮丰富,磷素不足;海拔及降水是西南茶区土壤养分的控制和驱动因子。从典则判别的土壤养分空间分异程度来看,贵州和四川较为相似,西藏和云南分异明显。不同土壤类型中,棕壤养分指标均达到优质高效高产茶园标准;黄棕壤总磷含量偏低;黄壤有效磷、全磷缺乏;砖红壤及红壤土壤酸化明显,有效磷、速效钾、全磷缺乏。不同地区间优质高效高产茶园养分达标率:西藏> 贵州> 云南> 四川。西南地区茶园土壤磷素的缺乏,已成为西南茶区发展的限制性养分因子。

    Abstract:

    To explore the characteristics and influencing factors of soil nutrient in tea gardens,literature measurement method is used to study tea garden soil in 4 provinces in southwest China,and the distribution and characteristics of soil nutrient under the different space,altitude,precipitation and soil type are analyzed. The results showed that the overall performance of the soil in southwest tea area is rich in organic matter,total nitrogen,and alkali-hydrolyzable nitrogen,but insufficient in phosphorus,and elevation and precipitation are the controlling and driving factors of soil nutrients. From the perspective of the degree of spatial differentiation of soil nutrients discriminated by the code,Guizhou and Sichuan are relatively similar,and Tibet and Yunnan have obvious differences. In different soil types,the nutrient indexes of brown soil reached the standard of high-quality and high-yield tea garden,the total phosphorus content of yellow brown soil is low,the available phosphorus and total phosphorus of yellow soil are deficient,the latosol soil and red soil are acidified obviously,and the available phosphorus,available potassium and total phosphorus are deficient. The rate of reaching the standard of high-quality and high-yield tea garden in different areas: Tibet>Guizhou>Yunnan>Sichuan. The deficiency of phosphorus in tea garden soil has become a limiting nutrient factor for the development of tea garden in southwest China.
