The invention discloses a
vegetation fiber composite earth and its process for preparing. The said composite earth is prepared by adopting the following materials according to a proportion by weight: 10-30 parts of fabric serum, 5-15 parts of
plant ash or
charcoal, 50-70 parts of soil, 0.8-1.2 parts of active
calcium, 0.5-1 parts of water-loss
reducer and 5-20 parts of water. The soil pore space of the composite earth obtained by this invention is filled with fabric serum,
plant ash and
moisture and the structure is more compact. The surface of the composite earth can produce shell because of the existence of the water, and the inside also contains water and
fertilizer which is suitable for the growth of the seed, which can guarantee the growth of the
vegetation and can prevent the dispersion of the rain, therefore, the invention has advantages that the thickness of the growth soil is proper, the water-retention effectiveness is good, and the product is of stable integrality, can prevent scouring and solarization, can reduce maintenance, and is no need of
precipitation. The product can be used in
vegetation greening on mountain rockslope, artificial slope and desert oralkali land.
