- 摘要:
- 以贵州山银花种植区为研究对象,通过野外实地考察、选点取样、指标测定、评价方法筛选及土壤综合肥力系数计算等一系列的分析和研究,对研究区域3个样地进行肥力评价。结果表明:样地Ⅰ(坡顶)、样地Ⅱ(坡腰)和样地Ⅲ(坡脚)土壤pH平均值分别为4.59、4.41、4.63;有机质平均含量分别为22.18、21.9、25.39 g/kg;全氮平均含量分别为0.99、0.89、1.00 g/kg;碱解氮平均含量分别为129.85、90.67、99.91 mg/kg;速效磷平均含量分别为13.44、15.41、18.35 mg/kg;速效钾平均含量分别为122.00、81.50、77.75 mg/kg。评价结果表明:样地Ⅰ、样地Ⅱ和样地Ⅲ的土壤肥力均属于肥沃水平,其中样地Ⅲ>样地Ⅰ>样地Ⅱ,土壤综合肥力系数(P综)分别为2.39、2.36和2.32。总体来看,山银花种植区土壤肥沃,其养分能满足山银花的生长。
- Abstract:
- Taking Lonicerae Flos as research object,the soil integrate fertility coefficient of Lonicerae Flos planting areas in Danzhai county of Guizhou province and evaluated the fertility of three sample plots were studied though the method of field investigation,sampling selection,index determination,evaluation screering and soil fertilizer calculation.The results showed that the average soil pH of plot Ⅰ(slope top),plot Ⅱ(mid slope),plot Ⅲ(basal slope) were 4.59,4.41,4.63;organic matter contents were 22.18 g/kg,21.9 g/kg,25.39 g/kg;total nitrogen contents were 0.99 g/kg,0.89 g/kg,1.00 g/kg;average alkaline hydrolytic nitrogen content was 129.85 mg/kg,90.67 mg/kg,99.91 mg/kg;average content of available phosphorus were 13.44 mg/kg,15.41 mg/kg,18.35 mg/kg;available K were 122.00 mg/kg,81.50 mg/kg,77.75 mg/kg.The evaluation results showed that:plot Ⅰ,plot Ⅱ and plot Ⅲ all belonged to fertile,in which plot Ⅲ was the largest and plot Ⅱ was the lowest,the soil integrate fertility coefficient were 2.39,2.36,2.32.Overall, Lonicerae Flos planting areas have such fertile soil which can satisfy the growth of it.
