不同成土母质对浦江桃形李品质的影响

Impacts of Different Soil Parent Material on Quality of Pujiang Peach-Shaped Plum

[目的]研究不同成土母质对桃形李品质的影响,为浦江县更好的发展规划桃形李产业提供依据。[方法]通过对浦江县的岩-土-果实及其根系土等进行全面、系统的调查,对比研究不同成土母质区的桃形李品质和岩石、土壤及根系土地球化学元素特征。[结果]浦江桃形李的品质与Ca、B、Zn呈正相关,与Si呈负相关;晚更新世红土风化物中桃形李品质最好,其次为中更新世红土风化物,酸性火山岩类风化物最差。[结论]浦江桃形李适宜种植在中晚更新世红土风化物的土壤中。

[Objective] The effects of different soil parent materials on quality of peach-shaped plum were studied to provide a basis for better development and planning on peach-shaped plum industry in Pujiang County.[Method] The quality of peach-shaped plum and rock,soil and root soil geochemical element characteristics in different soil parent material areas were stuied by conducting a comprehensive and systematic investigation on rock,soil,fruit and root soil in Pujiang County.[Result] The quality of Pujiang peach-shaped plum had a positive relationship with Ca,B,Zn and a negative correlation with Si.The peach-shaped plum which was planted on weathered Late Pleistocene clay had the best quality,followed by which was planted on weathered Mid Pleistocene clay,and the worst was the one planted on the weathering products of acid volcanic rocks.[Conclusion] Peach-shaped plum in Pujiang County should be planted on soil with weathering products of Mid or Late Pleistocene clay.
