Abstract:
With the speeding up of urbanization in our country，construction waste production is more and more increasing.In this experiment，the effects of the matrix of construction waste and commercial substrate on growth of tomato and lettuce transplants were studied to explore the possibility of construction waste as raw materials for the horticultural cultivation substrate.The results showed that with the increase in the volume ratio of construction waste to commercial substrate，pH and the bulk density significantly increased，and the organic matter content，water holding capacity，total porosity，NH4+-N and NO3--N content significantly decreased，and EC value increased and then decreased.Tomato and lettuce seedling fresh weight，dry weight，plant height and stem diameter increased and then decreased with the increase in the construction waste volume content in the compound substrate.The results suggested that construction waste volume content in compound substrate at 50% was more appropriate for the growth of tomato and lettuce transplants.
