- 摘要:
- 随着我国城市化进程的加快，建筑垃圾产生量越来越多。该研究通过建筑垃圾和商业基质进行复配，研究了其对番茄和生菜移植苗生长的影响，探讨建筑垃圾作为园艺栽培基质原料的可能性。结果表明：随着建筑垃圾体积含量的增加，复配基质中pH、容重随之升高，而有机质含量、持水量、总孔隙度、NH4+-N和NO3--N含量随之降低，EC值呈先升高后降低的趋势。番茄和生菜移植苗鲜质量、干质量、株高和茎粗均随着复配基质中建筑垃圾体积含量的增加呈先增加后减少的趋势。该研究结果表明，复配基质中建筑垃圾体积含量为50%时，番茄和生菜移植苗的生长最好。
- 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.
