摘要/Abstract

摘要：

采用野外调查和室内分析相结合的方法,研究不同植茶年限茶园土壤微团聚体的组成及其分形特征。结果表明: 茶园土壤微团聚体组成以0.25~0.05 mm粒级为主,占微团聚体总量的41.95%~55.44%,0.05~0.01 mm粒级次之,占23.54%~25.66%,<0.001 mm粒级所占比例最小,为5.80%~8.71%, 随植茶年限增加,0.25~0.05 mm粒级土壤微团聚体含量显著升高,0.05~0.01 mm和0.01~0.005 mm粒级含量变化不明显,而0.005~0.001 mm和<0.001 mm粒级含量则显著降低；随植茶年限增加,土壤微团聚体平均质量比表面积值、分形维数值和土壤特征微团聚体组成比例(<0.005 mm)/(0.25~0.05 mm)值均逐渐减小,而土壤微团聚体平均质量直径值则逐渐增大；不同植茶年限土壤微团聚体分形维数值和土壤特征微团聚体组成比例值均与土壤有机质含量、全氮含量、碱解氮含量、全磷含量和有效磷含量极显著负相关。长期植茶可促进土壤较小粒级微团聚体向较大粒级微团聚体转化,从而提高土壤微团聚体稳定性,土壤微团聚体分形维数值和土壤特征微团聚体组成比例值均可作为定量化描述茶园土壤肥力状况的指标。

Abstract:

Through a field survey and laboratory analysis, the composition and fractal features of soil micro-aggregates in different Camellia sinensis plantations with different ages were studied. Results showed that 0.25~0.05 mm fraction made up the largest proportion and accounted for 41.95%~55.44% of total micro-aggregates, followed by 0.05~0.01 mm fraction that accounted for 23.54%~25.66%, and <0.001 mm fraction accounted for the smallest proportion of 5.80%~8.71%. The percentage of 0.25~0.05 mm fraction presented an increasing trend as the increase in tea plantation age, however, the percentages of 0.005~0.001 mm and <0.001 mm fractions showed an inverse trend. Moreover, the values of mean weight soil surface area (MWSSA) and fractal dimension (D) of soil micro-aggregates and compositional proportion of characteristic soil micro-aggregates PCM (<0.005 mm)/(0.25~0.05 mm) presented a decreasing trend as the increase of tea plantation age, however, the value of mean weight diameter (MWD) of soil micro-aggregates displayed an increasing trend. The values of soil micro-aggregates D and soil PCM had negative correlation with contents of soil organic matter, total N and P and available N and P. Long-term tea planting was beneficial to promoting transformation from smaller soil micro-aggregates to larger micro-aggregates, thereby improving soil micro-aggregates stability. Thus, values of soil micro-aggregates D and soil PCM can be used as the quantitative evaluation indicators of soil fertility in tea plantations.

Key words: tea plantation age, soil micro-aggregates, composition feature, fractal feature
