Abstract: In order to study the spatial distribution characteristics of soil nutrients in Chuju planting areas, the villages and towns where Chuju was planted in Nanqiao District of Chuzhou and Quanjiao County were used as the research area. On the basis of ArcGIS and other software, the inverse distance weighting method was used to determine the soil Interpolation analysis of sampling data was carried out to study the spatial distribution of the four main nutrient elements of soil organic matter, total nitrogen, available phosphorus and available potassium in the Chuju planting area.
Key words:Chuju; organic matter; Total nitrogen; Available phosphorus; Available potassium; Inverse distance weigh;
滁菊主要產于安徽滁州,是菊花中花瓣最为紧密的一种。滁菊偏于平肝阳,常用于治疗肝阳上亢所致的头晕目眩等症,高血压中医辨证属肝阳上亢者可将滁菊、决明子代茶饮。《本草拾遗》记载菊花可“作枕明目”,头痛眩晕、目赤肿痛等属肝阳上亢者可使用滁菊做成药枕。
滁菊由于其优良的药用价值以及经济价值成为滁州的地理标志农产品,在极大程度上推动了农业发展,提高了农民收入。但滁州滁菊连续栽作20多年,在长期种植过程中产量品质有所下降,因此研究滁菊种植区域内的土壤养分空间分布有利于优质滁菊的扩大生产。
1 研究区概况
滁菊原产地地处江淮分水岭的丘陵地带,117°50′~118°30′E,32°05′~32°35′N,平均海拔60m。该区属北亚热带湿润季风气候,土壤为砂性土,呈酸性,富含麦饭石、绢云母等矿物质及锌、硒等多种微量元素。全年气候温和,四季分明,年平均气温15.2℃,年平均日照为2073.4h,年平均降雨量为1063mm[1]。原产地保护范围为滁州市南谯区大柳、珠龙、施集、章广4个镇和全椒县马厂、石沛、西王3个乡镇所辖行政区域。……
