羊草草地4种群落活根生物量与土壤理化性质的关系
The Relationship between Live Root Biomass and Phyviscal and Chemical Properties of Soil of 4 Communities in the Leymus chinensis Grassland
摘要
Abstract
Leymus chinensis grassland in Western Jilin Province as the study of natural samples,the choice often grazing in restoration succession process of the four kinds of plant communities as the research object,underground biomass,soil properties and their mutual relations between the two,the results show that 4 communities underground biomass of live roots with depth and the decreasing trend,and the total living root biomnss of L chinensis community ( shorthand com. ) ＞ L -Inula com. ＞ L -Puccinellia com. ＞ degraded com.; soil basicity, pH, soluble salts, electrical conductivity and water content in the four communities have shown with basic with the increase of soil depth trend, with the live root biomass mostly negative; and soil organic matter,hydrolysable N, available K,available P showed more soil depth with the downward trend,with the underground bio-consistent with the trend of volume,and with the live root biomass mostly positive.关键词
