沈阳东陵树莓种植区土壤养分状况调查与分析

Investigation and Analysis of Soil Nutrient in the Raspberry Planting Area in Dongling District of Shenyang

为了解沈阳东陵区树莓种植区域的土壤养分状况及分布情况,对该区域52个地点的土壤进行采样分析,并对测得数据分别进行了频率分析、描述性分析和聚类分析。结果表明:东陵树莓种植区域59.62%的土壤中有效铜含量在1.61～1.79mg/kg,36.54%的土壤中有效铁含量在15.34～24.08mg/kg,44.23%的土壤中有效锌含量在0.35～1.72mg/kg,51.92%的土壤中有效锰含量在27.33～35.39mg/kg。根据土壤主要养分在不同地区的含量和分级情况,将东陵区树莓种植区分为高氮中磷低钾区、高氮高磷高钾区、低氮低磷中钾区,其中,高氮中磷低钾区所占有的面积比例为19.2%;高氮高磷高钾区所占有的面积比例为32.7%;低氮低磷中钾区所占有的面积比例为40.4%。

In order to know the content and distribution of soil nutrient in the raspberry planting area in Dongling District of Shenyang,the soil samples from 52 regional locations in which covered the raspberry planting area were selected and analyzed. The measured data were carried out through the frequency analysis, descriptive analysis and cluster analysis. The results showed that the content of available Cu in Dongling raspberry planting area of 59. 62% was from 1.61 mg/kg to 1.79 mg/kg the content of available Fe in Dongling raspberry planting area of 36. 54% was from 15. 34 mg/kg to 24. 08 mg/kg; the content of available Zn in Dongling raspberry planting area of 44. 23% was from 0. 35 mg/kg to 1.72 mg/kg the content of available Mn in Dongling raspberry planting area of 51.92 was from 27. 33 mg/kg to 35. 39 mg/kg. According to the main nutrient content and grading of soil in different regions, the Dongling District raspberry planting area was divided into three zones.the area of high nitrogen, medium phosphorus and low potassium,the area of high nitrogen,high phosphorus and high potassium,tbe area of low nitrogen,low phosphorus and medium potassiurrL Among them, the ratio in the area of high nitrogen, medium phosphorus and low potassium was 19. 2% the ratio in the area of high nitrogen,high phosphorus and high potassium was 32. 7% the ratio in the area of low nitrogen,low phosphorus and medium potassium was 40. 4 %.
