4种草坪草菌根发育状况及其主要土壤影响因子
Mycorrhizal Development Status of Four Turfgrass Plants and Their Main Soil Influence Factors
摘要
Abstract
To reveal the main controlling factors affecting the development of turfgrass mycorrhiza,the present study was conducted to analyze the arbuscular mycorrhiza(AM) colonization in roots of four turf-grass plants,including Festuca arundiacea,Ophiopogon japonicus,Reineckea carnea,and Zoysia japonica, and further evaluate the relationship between mycorrhizal infection rate and contents of root soluble sugar, soil available phosphorus,soil organic carbon,organic matter,root and soil glomalin.The results indicated that root mycorrhizal infection rate in four turfgrass plants varied from 12.14% to 35.25%,and the root colonization was ranked as the trend of F.arundiacea>Z.japonica>O.japonicus>R.carnea.Root solu-ble sugar content was the highest in R.carnea(53.58 mg/g) and the lowest in Z.japonica(21.05 mg/g). Soil available phosphorus level was the highest in Z.japonica (10.34 mg/kg),and soil organic carbon and soil organic matter contents were the highest in O.japonicus.Correlation analysis showed that root my-corrhizal infection rate and entry points in turfgrass plants were significantly negatively correlated with soil organic carbon,organic matter,and easily extractable glomalin-related soil protein contents,and were sig-nificantly positively correlated with root difficultly-extractable glomalin content. It concluded that the my-corrhizal status of the four turfgrass plants was good in the field and could be regulated mainly by soil nu-trients,root soluble sugar and glomalin.关键词
