This invention belongs to the field of
plant cultivation technology, specifically relating to a
composite substrate for
Phalaenopsis orchid cultivation and its application, comprising:
sphagnum moss and fermented material, wherein the fermented material includes at least one of wolfberry
branch fermented material and
Caragana korshinskii
branch fermented material; the volume ratio of the
sphagnum moss to the fermented material is (5-7):(4-6). Experiments show that using the
composite substrate of this application to cultivate
Phalaenopsis orchids can promote healthy
plant growth. Compared with pure
sphagnum moss cultivation, the
plant height of
Phalaenopsis orchids increased by 15.03%,
leaf width increased by 25.42%, and the number of flowers increased by 64.7%; and there was no
significant difference in flower
diameter, internode length, stem thickness, leaf length,
leaf width,
pedicel length, and
pedicel thickness compared with sphagnum moss cultivation. At the same time, it greatly reduces the proportion of sphagnum moss used and the planting cost, and can realize the
resource utilization of regional agricultural and
forestry waste, promoting the development of ecological circular
agriculture.
