| 摘 要： | 通过对县城绿地及农田土壤有效氮磷钾含量的对比分析,研究了绿地植被对县城土壤有效养分含量的影响。研究结果表明:(1)县城绿地土壤有效养分含量同农田相比有一定差异,表现出有效磷含量绿地土壤低于农田,速效钾含量绿地土壤高于农田,而碱解氮规律不明显。(2)县城绿地植被不同其有效养分含量存在较大差异,一般表现出有效磷含量乔木>草坪、灌木,速效钾含量乔木、草坪>灌木,碱解氮含量表现出乔木>草坪、灌木;(3)绿地土壤基本性质对有效养分含量有一定影响,表现出速效钾与CEC呈极显著的线性正相关关系,碱解氮与有机质呈极显著的线性正相关关系。

| Abstract: | Through analysis on the green county and farmland through the N、P、K content in soil,this paper studied the effects of vegetation on soil nutrient content.The results show that:(1)there are some differences between the green space and the farmland,and the nutrients of P in green county are lower than in the farmland,but it is contrary with the K;(2)There are some big differences in the green county;as to the P:The Arbor>The Lawn and The Bush,as to the K:The Arbor and The Lawn>The Bush,as to the N:The Arbor>The Lawn and The Bush.(3)The basic properties of the garden soil have some effects on the nutrients.It shows in the significant linear positive correlation between the K and the CEC,it’s similar with the N and the organic matter. |
