The invention discloses a slope
greening method for the southwest region. The method comprises the following steps that soil replacement is conducted on slopes;
native plant seeds of the southwest region and introduced
plant seeds or naturalized
plant seeds which are suitable for growing in the southwest region are sowed in a spraying mode on the slopes, wherein the
native plant seeds comprise the
hypericum patulum seeds and
pyracantha fortuneana seeds,
hypericum patulum is a semi-
evergreen shrub and has the advantages that the
insect pest injury resistance and the
disease resistance are high, meanwhile, the
hypericum patulum grows in a branching mode, the
plant height is moderate, the emergence rate of the seeds is high, the flowering stage is long, the
growth speed is high, and the
hypericum patulum can bloom after one year the
hypericum patulum seeds are sowed in a spraying mode;
pyracantha fortuneana is an
evergreen shrub and has the advantages of being resistant to drought and barren, resistant to defoliation, dense in
branch and leaf and developed in
root system, flowers are blooming in spring, fruits are countless in autumn, and the
pyracantha fortuneana is a good
tree species for
landscaping and conservation of water and soil. The method is high in
operability, simple in maintenance, quick in green
recovery, long in flower viewing stage, resistant to water and
soil loss, high in slope protection ability of the
root system, good in landscape effect, good in phytocoenosium stability and capable of improving the landscapes on the road side slopes in winter.
