摘要
为了综合评价平和县典型琯溪蜜柚果园土壤肥力状况,根据琯溪蜜柚种植面积采集42个福建省漳州市平和县琯溪蜜柚果园内具有代表性的基础土壤样品,以土壤pH、全氮、全磷、全钾、有机质等13个指标建立肥力指标体系,利用SPSS统计软件,结合主成分分析和聚类分析,对各琯溪蜜柚果园单元土壤综合肥力进行评价。结果显示,平和县琯溪蜜柚果园土壤pH以强酸性和酸性为主,全氮、全磷、全钾中等偏多,处于丰富或一般水平;碱解氮含量稍高于中等速度水平,速效磷和速效钾含量稍低于中等水平,主要处于丰富或缺乏水平;有机质含量、交换性钙、交换性镁、速效硼含量普遍不足;土壤速效锰、速效锌含量大部分适宜;各区域土壤养分指标均存在中等程度的变异,其中,速效钾、速效锌和速效硼的变异范围较大;按累计贡献率达87%以上提取了5个主成分,根据5个主成分计算综合得分,将13个琯溪蜜柚果园土壤分为Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ5个等级,各等级分别所占的比例为7.14%、14.29%、16.67%、45.24%和16.67%;第Ⅰ级主要为小溪镇蜜柚果园,第Ⅱ级主要为文峰镇和坂仔镇蜜柚果园,第Ⅲ级主要为南胜镇蜜柚果园,第Ⅳ和Ⅴ级主要为霞寨镇、国强乡、大溪镇、安厚镇、五寨乡、九峰镇、崎岭乡、芦溪镇、山格镇和秀峰镇蜜柚果园,该区域土壤养分比较缺乏。
Thirteen indices of soil samples were collected to evaluate the nutrient and fertility suitability of Guanxi honey pomelo soil in 42 Pinghe base units Zhangzhou City of Fujian Province, which were pH, total N, total P, total K,organic matter, etc. To use of SPSS statistical software, combined with principal component analysis and cluster analysis to evaluate the pomelo unit soil fertility. The results indicated that Guanxi honey pomelo of Pinghe with strong acidic and acidic soil pH, total nitrogen, total phosphorus, total potassium medium, mainly in the rich or the general level. The available nitrogen was much more moderate, available phosphorus and available potassium of content was moderate, which was mainly in abundance or lack of level;The content of organic matter, exchangeable calcium, magnesium, the content of available boron was generally insufficient;the soil available manganese and zinc content were most suitable, the soil nutrient indexes in different regions had moderate variation in Chengdu, among which available potassium, available zinc and available boron had a wide range of variation;Five principal components were obtained which accounted for 87%, the total information reflected by original 13 indexes. The systemic cluster graph was gained based on the general scores of 42 soil samples. According to the cluster graph modulus, the soil samples were divided into Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ grades, the proportion of each grade was 7.14%, 14.29%, 16.67%, 45.24% and 16.67% respectively. The general score of honey pomelo garden in Pinghe reached Ⅰ grade, followed by Wenfeng, Banzai counties which reached Ⅱ grade and Nansheng reached Ⅲ grade, Xiazhai, Guoqiang, Daxi, Anhou, Wuzhai, Jiufeng, Qiling, Luxi and Shange counties reached Ⅳ,Ⅴ grade which soil in low fertility.
