Rock fill slope is a common slope type on mountain roads with surface layer consisting of different sizes of broken rocks but little soil

this poor site condition brings great difficulty to the vegetation restorat ion.To solve this problem

the tree(shrub)herb community was constructed using the nursery block and soil spray-sowing technique.Taking the 45b rock fill slope at the 11km of Baihuashan tourism road in Mentougou

Beijing City as an example

the coverage of her baceous plants was around 50%

and the average height was 40 cm four years later after the technique was use.Meanw hile

the woody plants grew well with sturdy taproots and strong lateral roots penetrating into rock cracks

and the survival rate of Prunus davidiana was 78% with the height of 82 cm and the ground diameter of 7.9 mm.The results showed that the tree(shrub)herb community could be successfully constructed on relatively steep rock fill slopes by using t his technique.
