Leaves return to roots

There are many leaves falling down the street in autumn,it is inconvenient for dustman to clean the leaves,because it is difficult to transport and dispose.Even some people take the way of buring them directly,which will cause the great pollution for environment.Why can not we recover the leaves and use them again?As the saying goes,Fallen leaves return to the roots-to revert to one's origin,so that we design the equipment.It can collect these leaves to change them into fertilizer,and then we can put into fertilizer to the root of tree by washing of rain.It is easy and economical and also can realize the aim of environmental protection.
