The invention discloses a space
moss and
haloxylon ammodendron co-culture
mutagenesis method, which relates to the field of space breeding and desert ecological restoration, and comprises the following steps: material pretreatment, co-culture
system construction, space carrying
mutagenesis, gradient
domestication culture after returning,
mutant screening and excellent strain propagation. The method comprises the following steps: selecting high-quality
moss spores and
haloxylon ammodendron seeds, constructing a co-culture
system, feeding the co-culture
system into a space carrying platform, carrying out co-culture
mutagenesis for 10-15 days in a composite environment with microgravity of 10 <-3 >-10 <-6 > g and cosmic
radiation of 0.5-2.0 Gy, returning the co-culture system to the ground, carrying out gradient
domestication, and screening excellent strains of which the
stress resistance, the sand stabilization capability and the symbiotic suitability reach the standard. According to the method, space synchronous mutagenesis of
moss and
haloxylon ammodendron is achieved, the symbiotic synergistic effect is enhanced, the symbiont
stress resistance index after mutagenesis is improved by 30% or above compared with a conventional strain, the sand stabilization and soil improvement efficiency is improved by 35% or above, the technical
operability is high, and the method can be applied to desert ecological restoration on a large scale.
