155元。Based on zone tillage theory, a paired-site design was adopted to qualitatively and quantitatively evaluate the effect of situ-vibration tillage on Leymus chinensis grassland, which would be applied to provide theoretical reference and technical support for restoring degraded Leymus chinensis grassland. Results showed that the soil bulk density decreased, soil water holding capacity and water content increased and the content of soil nutrient increase to some extent after the grassland scarified; the height, cover, density of grass vegetation, above and below-ground yield, proportion of excellent and good forges and grassland plant diversity all increased, the yearly average economic benefit from the grassland soil scarifying was 155 RMB/hm2 in next 3 year.
