摘　　要：为研究覆膜栽培技术对山东黄芩质量和土壤环境的影响,为黄芩的规范化栽培和质量提高提供理论依据,2013年对黄芩的生物学特性进行田间统计,利用土壤参数快速测定仪测定土壤理化性质,HPLC测定黄芩中黄芩苷的含量。结果表明,覆盖地膜能使黄芩在整个生育期内对铵态氮的吸收比露地栽培增加26.84%（0∽10cm）和9.00%（10∽20cm）;有机质分别增加了14.0%（0∽10cm）和6.7%（10∽20cm）。覆膜处理提高了土壤对速效钾和速效磷的供肥能力,覆膜处理0∽10cm和10∽20cm土层中速效钾的含量分别比露地处理增加了68.94%和13.60%;速效磷分别增加了40.92%和28.68%;覆盖地膜能够提高黄芩中黄芩苷的含量,较露地栽培提高了17.80%。覆膜栽培技术能够促进黄芩对铵态氮的吸收,增加土壤有机质含量,提高黄芩的产量和有效成分含量,并具有较好的保温保肥作用,对指导传统种植区域的生产具有重要意义。The objective of the research was to study the influence of coveting plastic mulch on the content of ac- tive components in Scutellaria Baicalensis Georgi and the environment of soil, providing the method to improve the cultivation and quality of this medicine plant. The biological characteristic was investigated in field, and the contents of baicalin was detected by HPLC. Soil multi-parameter analyzer was used to measure soil physical and chemical properties. The results showed that the plastic film covering cultivation mad Scutellaria Baicalensis Georgi absorb ammonium 26.84% （0 - 10era） and 9.00% （ 10 - 20em） and organic content was 14.0% （0 - 10cm） and 6.7% （10-20cm） more than the traditional cultivation during the all growing period. While,the content of available K and available P were increased in the plastic film covering cultivation at the depth of （0 - 10）cm and （ 10 -20） by 68.94% ,40.92% and 13.6% ,28.68% respectively. The content of baicalin was increased 17.80% in the plastic film covering cultivation. The plastic film coveting cultivation could increase ammonium absorption by plant and organic matter content in soil, improve yield and quality of Scutellaria Baicalensis Georgi, and keep soil temperature and fertility steady, implying that there is a good guidance effect on Scutellaria Baicalensis Georgi production in this area.
