Abstract:In order to make up low-priced substrates that is suitable for vegetables seeding in hole tray and replace turf and other expensive materials,edible fungus slag,decay leaf,slag and other industrial and agricultural wastes were used as raw material in this experiment.A series of substrates were made up and they were investigated and screened from such aspects as the total porosity,ventilation porosity,hold water porosity,size porosity ratio,bulk density,pH,acid-base buffering capacity,N,P,K and organic matter content and seeding experiment,etc.Finally,three groups with excellent performance were selected.They were suitable for being popularized.This study provided certain reference for the development of industry of vegetable seeding.
