Abstract: The effective collection and composting of garden waste can make it a good cultivating substrate and accelerate plant growth at the same time. The aim of this experiment was to study how the garden waste compost products influenced the growth and blooming of Tagetes erecta under the different conditions of matters, microbial inoculums and water contents. The results demonstrated that when using the mixture of pig manure and fallen leaves as the compost substrate, the water content of 65% and the ventilation time of 10 min/d constitute the most appropriate composting condition of the garden waste, under this condition, the highest morphological comprehensive evaluation index of Tagetes erecta plant was obtained regardless of any microbe additive. Therefore, compost with No. 3 microbial inoculum Aspergillus sp. was most beneficial for Tagetes erecta growth, and could be a possible choice for foliage plant cultivation. Compost with No. 2 microbial inoculum Streptomyces sp. benefited not only Tagetes erecta growth but also its flowering, and could be an appropriate additive microbial inoculum for flowering plant cultivation.
