中江县丹参产区的生态环境与土壤条件

摘要

对中江县丹参产区生态环境和土壤条件的调查研究结果表明：丹参主要栽培在该县西北部低山区海拔600～900m的坡地，气候温暖湿润，主产土壤为中壤质的石灰性和中性紫色土。一般土壤有机质和氮、钾属于中低水平，速效磷丰富；在微量营养元素中，有效铁、锰、铜充足，有效锌、硼普遍较缺乏。%Investigation of ecological environment and soil condition of Salvia miltiorrhiza Bge productive area in Zhongjiang County, Sichuan Province, shows that Salvia miltiorrhiza Bge is mostly planted in sloping fields on the north-western part of low mountain area with altitude of 600～900 meters in that county. It is of warm and moist weather whose main productive soil is of mid-soil-quality of calcareous and neutral purple soil. In general, soil organic matter and nitrogen-potassium content are in the range of middle or low level, but rich in phosphorour, iron, manganese copper. While zince and boron are extremely short.
