民乐县黄芪耕地土壤肥力状况研究及评价

通过对民乐县药材黄芪28份耕地土壤进行pH、可溶性盐、有机质、全氮、全磷、有机磷、速效钾七个指标的研究测定和分析,得出民乐县黄芪耕地土壤肥力的基本状况,结论为:民乐县道地药材黄芪耕地土壤在不同等级间土壤肥力存在较大差异,全氮和速效钾部分地区呈缺乏状态,土壤酸碱度偏碱性,有机磷含量丰富,可溶性盐、有机质、全磷较丰富。针对该现状,文中提出合理的解决措施,为民乐县扩大化、规范化种植黄芪药材提供理论依据。

Study and evaluation of soil fertility of astragalusin cultivated land in minle county

Through the determination and analysis of the seven indexes of pH, soluble salt, organic matter, total nitrogen, total phosphorus, organic phosphorus and available potassium in 28 cultivated soils of Mind"s medicinal materials, the basics of soil fertility in the farmland of Minle County were obtained. The situation is as follows: the soil fertility of different soils in the soil of Astragalus membranaceus in Minle County is quite different. The areas of total nitrogen and available potassium are in a state of deficiency, the soil pH is alkaline, the content of organic phosphorus is rich, soluble salt and organic matter. It is rich in total phosphorus. In view of the current situation, it puts forward reasonable solutions to provide a theoretical basis for the expansion and standardization of the cultivation of Astragalus membranaceus.
