Abstract:
Turf grass clippings and fallen leaves from Populus alba ‘Berolinensis’ L.& Hosta plantaginea Aschers.were used as the tested object,the indoor culture method was adopted in this article to study the effects of different ratios of turf grass clippings to fallen leaves from Populus alba ‘Berolinensis’ L.& Hosta plantaginea Aschers.4∶1,1∶1 and 1∶4 on the C contents of water-soluble organic carbon,humic-extracted acid,humic acid,fulvic acid and humin (WSOC,CHE,CHA,CFA and CHu) of mixed materials in their decomposition process in order to provide scientific basis for the resource utilization of garden solid waste.The results showed that no matter what the ratio of mixed materials was,the CHE and CHA could be accumulated after the culture,and the ratio of 1∶4 had the greatest promotion degree to CHE.In this process,the greater degrees of consumption and decomposition of WSOC and CHu components were showed by the microorganisms.The 4∶1 ratio of mixed materials was more conducive to the formation of CHA,and it had the greatest promotion degree to the CHA/CFA ratio,which was increased to 67.4%,followed by the 1∶1 ratio.The mass ratio of turf grass clippings to fallen leaves from Populus alba ‘Berolinensis’ L.& Hosta plantaginea Aschers.of 1∶1 had the promotion effect on the simplification of HA molecular structure after 60 days,on the contrary,the HA molecular structure of mixed materials was tended to the simple direction from the 4∶1 or 1∶4 ratio.To sum up,when the ratio of turf grass clippings to fallen leaves from Populus alba ‘Berolinensis’ L.& Hosta plantaginea Aschers.was 4∶1,the promotion effect on the maturity extent of the mixed materials was the most significant.
