摘要:

利用现有的数据,分析蚯蚓密度与土壤物理肥力主要参数之间的关系,定量评价蚯蚓对土壤物理性状的影响。通过中国知网和Web of Science,输入关键词(蚯蚓、土壤容重、土壤含水量、土壤质地、土壤孔隙度、土壤水稳定性团聚体)搜索,提取其中相关的数据,将文献提取的数据与调研获得的数据结合,进行Pearson相关性分析。研究发现,蚯蚓密度与砂粒相对含量呈极显著的负指数关系(P<0.001),与粉粒相对含量呈显著的正指数关系(P<0.05),而与黏粒相对含量呈极显著的幂函数关系(P<0.001);与土壤容重呈微弱的负相关关系(P<0.20),但与土壤孔隙度呈显著的正相关关系(P<0.05);与水稳定性团聚体含量呈微弱的正相关关系(P<0.5),但与水分含量呈极显著的正相关关系(P<0.001)。基于蚯蚓密度与砂粒、粉粒、黏粒相对含量,土壤容重、孔隙度,水稳定性团聚体、水分含量关系,可以将蚯蚓密度与土壤物理肥力主要参数之间的定量关系分为5个等级,以用于评价蚯蚓对土壤物理肥力指标的影响。

Abstract:

This study was aimed to analyze the relationship between earthworm density and the main parameters of soil physical fertility, and quantitatively evaluate the impact of earthworms on soil physical properties through field samples and data collection from literatures. Relevant data was extracted by inputting keywords such as earthworm, soil bulk density, soil water content, soil texture, soil porosity, and soil water-stable aggregates in the China Knowledge Infrastructure and Web of Science. The data extracted from the literature was combined with the data we obtained to perform Pearson correlation analysis. It was found that earthworm density was significantly, negatively and exponentially related with sand percentage (P<0.001), and significantly, positively and exponentially related with silt percentage (P<0.05) while significantly related with clay percentage in power function (P<0.001). There was a weak negative correlation with soil bulk density (P<0.20), and a significant positive correlation with soil porosity (P<0.05). There was a weak positive correlation with water stable aggregate content (P<0.5), but a very significant positive correlation with water content (P<0.001). The quantitative relationship between earthworm density and the main parameters of soil physical fertility can be divided into five classes according to the relationships between earthworm density and the relative content of sand, silt and clay, soil bulk density, porosity, water stability aggregate and water content, which may be valuable for estimating the impacts of earthworm on soil physical fertility.

Key words: earthworm density, clay, silt, sand, bulk density, porosity, water-stable aggregates, soil moisture
