The invention discloses a method of
calotropis gigantea L. mycorrhization container
seedling breeding. The method comprises the following processes: treating seeds, preparing a substrate, carrying outmatrix
inoculation,
sowing the seeds, carrying out management in a
seedling stage and taking seedlings out of a nursery. Qualified seeds are selected for disinfection treatment; then carrying out
germination acceleration; after white is exposed on the seeds, the seeds are sowed into the pre-prepared matrix inoculated with a strain; and high-quality
calotropis gigantea L. container seedlings are obtained through management and
nursing in the
seedling stage. According to the method provided by the invention, in order to solve the characteristics of
slow growth, less developed
root system, and easy infection of
root rot and
stem rot of the
calotropis gigantea L. in a young seedling stage, the effects of root enrichment,
growth promotion, seedling strengthening, and
disease prevention of
mycorrhiza are fully utilized, the quality of the calotropis
gigantea L. seedlings is improved, the resistance of the seedlings is enhanced, the
survival rate of the seedlings is improved and reaches 90%or above, the
mycorrhiza has the capacity of self-fertilization, and the supplement of external fertilizers can be reduced in the seedling stage, so that the seedling breeding cost is reduced.
