The invention relates to the technical field of environment protection and
greening of side slopes, and provides a spray
seedling matrix for regreening of bare side slope adapted to soil in
arid and semi-
arid zones and a preparation method of the spray seeding matrix. The spray
seedling matrix provided by the invention is prepared from the following raw materials in parts by weight: 25 to 40 parts of composted organic wastes, 30 to 40 parts of side slope
loess, 5 to 15 parts of kaolin, 0.5-0.8 part of
potassium fulvate, 5 to 15 parts of
bentonite clay, 3 to 4 parts of flour sticky glue and 5 to 10 parts of
plant fibers. According to the spray
seedling matrix, intensive aboveground parts and developed root systems of plants can be quickly formed on the long-term
arid and bare side slope, regreening of the side slope can be effectively carried out, the soil is consolidated, and
surface runoff and
soil washing can be prevented and controlled. The preparation method provided by the invention comprises the steps of mixing the composted organic wastes, the side slope
loess, the kaolin, the
potassium fulvate and the
bentonite clay and pulverizing into particles; then mixing the particles with the
plant fibers to obtain a mixture; successively, adding water and stirring the mixture to form a viscous state; then mixing the viscous product with the flour sticky glue. The preparation method has the advantages of simple technology, strong
operability and benefit to industrial production.
