Empirical Study on the Suitability of Different Planting Methods of Eremochloa ophiuroides for Embankments in Poyang Lake Areas
The vegetation structure of river and lake embankments is complex,and there are many weeds and miscellaneous irrigation,which hinders the inspection of embankments.The research and development of new high-tech embankment planting technology has important practical needs and broad application prospects.Eremochloa ophiuroides,with low and dense grass has outstanding ad-vantages in reducing daily management costs of embankments and flood season inspection,is a very suitable species for levee plant slope protection.Taking Chengzhu Lianwei,a typical embankment in Poyang lake district,as the research area,an empirical study was conducted on the changes in cov-erage degree,lawn grass height,and inhibition of weed invasion on the embankment slope under three planting ways:intercropping of fake frugal grass,stem segment strip sowing,and grass stems spreading(Sprinkling-Soil cover-Rolling).The results showed that the coverage of turf could be increased from 20%to 65%within 3 months under both grass stem sowing and spreading methods.The control efficiency for three consecutive years from 2020 to 2022 reached 31.48%to 71.03%,and the vegetation community composition was significantly different from the control slope.The cost of intercropping was higher than that of stem sowing and spreading,and the coverage speed of so-wing was higher than that of spreading.However,there was no significant difference in height con-trol and weed suppression between the two stem planting,but the cost of sowing was lower than that of spreading.Eremochloa ophiuroides can be used for vegetation management of river and lake em-bankments,and stem sowing was suitable for large-scale promotion and application.
