    Technical Field
    The present invention relates to the field of agricultural machines, in particular to a doublesided weeding machine specially for Chinese wolfberry plantation.
    Background Art
    The nutritional value of Chinese wolfberry is ven- high, and therefore Chinese wolfberry is planted in a large area. And in the large area plantation of Chinese wolfberry, mechanized field management is required to satisfy the requirements for the plantation efficiency and yield of Chinese wolfberry.
    The large area plantation of Chinese wolfberry' requires manual weeding and intertillage operations which waste time and labor, and the working efficiency is comparatively low . A Chinese wolfberry' plantation machine in the prior art can only intertill an area between two rows, but cannot simultaneously eradicate the weeds near Chinese wolfberry' trees. Therefore, human assistance is required to eradicate tire weeds near the Chinese wolfberry trees. Hence, the working efficiency of the mechanized field management of Chinese wolfberry is comparatively low.
