| 摘 要： | 为了加快园林绿化废弃物堆肥腐熟化进程、减少环境污染、实现资源的循环利用,于2011年5月在北京市香山公园,以春季园林绿化废弃物为主要原料,添加适当比例干鸡粪进行高温堆肥试验,主要研究了园林绿化废弃物堆肥体系中加入糠醛渣后温度、全氮、C/N比、植物抑制物质的动态变化及其对园林绿化废弃物堆肥产品品质的影响。结果表明,纯园林绿化废弃物堆肥的最高温度为46℃,GI值最高为71%,未达到堆肥腐熟要求;添加糠醛渣的园林绿化废弃物堆肥,在堆肥第3天后进入高温分解阶段,持续时间为14天,较仅添加鸡粪的处理2进入高温分解时间提前了2天,高温持续时间延长了4天。至堆肥结束,添加糠醛渣的处理3全氮含量较处理2增加了12.4%,较处理1增加了36%,3种处理的种子发芽指数分别为73%、87%、90%。添加糠醛渣的处理3可以显著增加园林绿化废弃物堆肥产品的N、P、K养分含量,降低产品容重,提高堆肥总孔隙度和持水孔隙度,改善堆肥产品的品质。

| Abstract: | In order to speed up maturity of the garden waste composting, moreover to reduce the pollution of environment and realize the resource recycling, the experiment was conducted by using mixtures of spring garden waste and dry chicken manure to study the effects of furfural residue on composting process in Xiangshan Park of Beijing in May 2011. The author researched on the dynamical changes of temperature, the contents of total-nitrogen, C/N ratio, plant inhibited material in the composting process and the compost qualities of the different composting treatments. The results showed that in the treatment of garden waste composting without furfural residue, the highest temperature was 46℃, GI was 73%, it did not reach the stage of maturity; In the treatment with furfural residue, the time of reaching the highest temperature was 3 days and the sustaining of high temperature decomposing was 14 days. Compared with the garden waste composting treatment, with proper ratio of dry chicken manure, the time of reaching the highest temperature shortened by 2 days and the sustaining of high temperature extended by 4 days. Compared with the treatment 1 and treatment 2, the content of total-N in the treatment 3 improved by 12.4% and 36%, respectively. The GI was 73%, 87% and 90%, respectively until the end of composting. At the maturity, it was found that the composting treatment with furfural residue, had higher contents of available nitrogen, available phosphorus, available potassium,higher total porosity and water-holding porosity, and lower the bulk density, compared with the garden waste treatment and the garden waste compost treatment with the prosper ratio of dry chicken manure, the treatment with furfural residue could improve the compost quality significantly. |
