为研究绿化植物废弃物与不同调理剂混合堆肥的效果,设置空白对照(处理1)、添加尿素(处理2)、添加尿素和菌剂(处理3)、添加尿素、菌剂和烟气脱硫石膏(处理4)4个处理,进行为期197 d 的堆肥试验。结果表明:尿素和菌剂对堆体的 pH 和 EC 值影响不大,烟气脱硫石膏能调节堆体的 pH 并提高堆体 EC 值;堆肥结束时,处理1的有机质分解效果不明显,处理2—处理4的有机质分解率依次为4.7%、5.8%、14.8%;4个处理的总养分在整个堆肥期间均呈上升趋势,堆肥结束时4个处理的总养分含量依次为4.07%、4.85%、5.31%和6.06%,均符合有机肥或有机基质相关质量要求;4个处理的终点 C?N 依次为22、17、16和12。添加尿素、菌剂、烟气脱硫石膏均能促进有机物质的分解,加速堆体腐熟,提高堆肥产品的质量,以处理4的堆肥效果最好。
為研究綠化植物廢棄物與不同調理劑混閤堆肥的效果,設置空白對照(處理1)、添加尿素(處理2)、添加尿素和菌劑(處理3)、添加尿素、菌劑和煙氣脫硫石膏(處理4)4箇處理,進行為期197 d 的堆肥試驗。結果錶明:尿素和菌劑對堆體的 pH 和 EC 值影響不大,煙氣脫硫石膏能調節堆體的 pH 併提高堆體 EC 值;堆肥結束時,處理1的有機質分解效果不明顯,處理2—處理4的有機質分解率依次為4.7%、5.8%、14.8%;4箇處理的總養分在整箇堆肥期間均呈上升趨勢,堆肥結束時4箇處理的總養分含量依次為4.07%、4.85%、5.31%和6.06%,均符閤有機肥或有機基質相關質量要求;4箇處理的終點 C?N 依次為22、17、16和12。添加尿素、菌劑、煙氣脫硫石膏均能促進有機物質的分解,加速堆體腐熟,提高堆肥產品的質量,以處理4的堆肥效果最好。

To study the effect of different amendments on composting of greenery waste,treatment 1(green-ery waste only),treatment 2(greenery waste add urea),treatment 3(greenery waste add urea and bacterial rea-gent),treatment 4(greenery waste add urea,bacterial reagent and flue gas desulfurization gypsum)were carried out for 197 days.The results showed that,adding flue gas desulfurization gypsum could adjust pH and improve e-lectrical conductivity(EC)value,however,urea and bacterial reagent had no effect on pH and EC.During com-posting,the content of organic matter in treatment 1 did not change obviously,the decomposition rate of organic matter of treatment 2,3,4 was 4.7%,5.8%,14.8% respectively;The total nutrient increased in the whole composting period.when the experiment was finished,the content of total nutrient was 4.07%,4.85%,5.31%and 6.06%,final C?N in 4 treatments was 22,17,16 and 12 respectively.Therefore,above 3 individual amend-ments such as urea,bacterial reagent,flue gas desulfurization gypsum could promote the decomposition of organic matter,accelerate the composting maturity and improve the compost quality.Moreover the composting of treatment 4 had the most positive effect in 4 treatments.
