摘要

利用丛枝菌根真菌(AMF)提高土壤对磷的吸收是一种被认为可以治疗土壤缺磷的生物技术。本研究调查了肯尼亚的Aspilia pruliseta Schweif灌木和AMF的关系。该研究旨在分析一种具有多种生态效益的热带灌木,这种灌木可以减少向土壤中添加化学磷肥,并扭转富营养化的负面后果。采样的目的是让有或没有鸭嘴草植被的地区生长。少量(10 g) 来自27个复合样品的土壤中的一个用于孢子计数测定,并将类似数量用于下一代测序。孢子数在土壤质地类型、样品位置和土壤深度之间存在显著差异。沙壤土的孢子数最高,平均为404个孢子。孢子数显著下降(P < .05),根际土壤深度从平均514个孢子到185个孢子。孢子形态类型的强度在P < .05的土壤比没有覆盖的土壤。与沙壤土一起使用的鸭嘴草植被可以培养商业菌根真菌生产,用于农业系统。

Arbuscular Mycorrhizal Fungi Colonization in the Rhizosphere of Aspilia pruliseta Schweif. ext Schweif in the Semiarid Eastern Kenya
The use of arbuscular mycorrhizal fungi (AMF) to enhance soil phosphate uptake is a biological technique considered to cure phosphate deficiency in soils. This study investigated association of Aspilia pruliseta Schweif shrub with AMF in Kenya. The study aims at profiling a tropical shrub with multiple ecological benefits that could reduce addition of chemical phosphatic fertilizer into the soil and reverse negative consequences of eutrophication. Sampling was purposive to have areas with or without Aspilia pruliseta vegetation growing. A small amount (10 g) of the soil from 27 composite samples was used for spore count determination and a similar amount for next generation sequencing. Spore counts varied significantly among soil textural types, sample locations, and soil depth. Sandy loam had the highest spore counts with a mean average of 404 spores. The spore count decreased significantly (P < .05) with the depth of soil from a mean of 514 spores to 185 along the rhizosphere. The intensity of spore morphotypes was significantly higher at P < .05 for soils whose vegetation was covered with Aspilia pruliseta than those without. Aspilia pruliseta vegetation used together with sandy loam soil could culture commercial mycorrhiza fungi production for use in agrisystems.

期刊介绍: Air, Soil & Water Research is an open access, peer reviewed international journal covering all areas of research into soil, air and water. The journal looks at each aspect individually, as well as how they interact, with each other and different components of the environment. This includes properties (including physical, chemical, biochemical and biological), analysis, microbiology, chemicals and pollution, consequences for plants and crops, soil hydrology, changes and consequences of change, social issues, and more. The journal welcomes readerships from all fields, but hopes to be particularly profitable to analytical and water chemists and geologists as well as chemical, environmental, petrochemical, water treatment, geophysics and geological engineers. The journal has a multi-disciplinary approach and includes research, results, theory, models, analysis, applications and reviews. Work in lab or field is applicable. Of particular interest are manuscripts relating to environmental concerns. Other possible topics include, but are not limited to: Properties and analysis covering all areas of research into soil, air and water individually as well as how they interact with each other and different components of the environment Soil hydrology and microbiology Changes and consequences of environmental change, chemicals and pollution.
