Located experiment in 3 years indicates that Humulus scandens is not only a kind of good forage grass resources

but also a soil and water conservation herb which has strong capacity to fix and protect soil.It is a kind of ideal grass vegetation to afforest barren mountain

slop and gully

to improve ecological environment of the loess plateau.The coverage could be 80% within the seeding year and more than 90% the next year.The result with synthetical calculation and analyzing indicates that the water conserving efficiency of Humulus scandens combined with simply soil and water conservation physical measures is 46%

and the sand reducing efficiency is 75.9%.
