河南省烤烟种植区土壤综合肥力评价
|
摘要
在分析河南省烤烟种植区各项肥力因子的基础上,对该区域内植烟田土壤肥力进行了综合评价。根据S型或抛物线型作物效应曲线建立了各项评价指标的隶属函数,采用主成分分析法确定了各评价因子权重,从而求得每个评价单元的综合指标值。使用MAPGIS地理信息系统软件,建立了该区域内植烟田土壤综合肥力适宜性评价图。研究表明:研究区内的信阳市全部和南阳市的西部由于土壤中有机质丰富,pH值适宜,全N含量高,因此土壤综合肥力为最适宜区,这部分面积为1.18万hm2,占河南省烟草种植总面积的13.69%;驻马店、许昌、平顶山和洛阳由于Cl-含量适中,有效P和有效K含量丰富,因此土壤综合肥力为适宜区,这部分面积为3.03万hm2,占河南省烟草种植总面积的35.01%,河南省北部和东部的一些烟草种植区由于pH值和Cl-含量太高,P的有效性偏低,因此土壤综合肥力为次适宜区,这部分面积为4.24万hm2,占河南省烟草种植总面积的48.86%。
Based on analysis of the physical and chemical properties of soil samples collected from He'nan tobacco planting regions,the index system of soil fertility suitability of tobacco was established.S-or parabola-type dependence functions were developed according to their effects on tobacco crop and the function value was also calculated.AHP was applied to judge the weight of each evaluation factor.Then the integrated index va1ues for every evaluation unit were obtained.Based on all the above,the fertility map of He'nan tobacco planting regions was drawn with MAPGIS.It is found that the whole Xinyang city and the west of Nanyang are the highly suitable regions,which is 1.18×104 hm2,accounting for 13.69% of He'nan tobacco planting regions.It is due to that there is rich in organic matter and total N,and there is suitable pH value in the soils in this regions.There are suitable areas for planting tobacco crops in Zhumadian,Xuchang,Pingdingshan and Luoyang city,because there are medium Cl-contents,and there is rich in available P and available K in these regions,which is 3.03×104 hm2,accounting for 35.01% of He'nan tobacco planting regions.There are less suitable regions in the northern and eastern parts of the investigated regions because of too higher contents of Cl-and pH,and too lower contents of available P,which is 4.24×104 hm2,accounting for 48.86% of He'nan tobacco planting regions.
