旨在研究强制通风系统中不同通风速率0.1、0.2、0.3和0.4m3·h^-1·m^-3堆体(处理A、B、C和D)对烟草废弃物好氧堆肥理化性质及种子发芽率的影响.A、B、C三处理堆肥温度超过55℃连续三天以上,D处理堆肥温度超过55℃只维持了一天.B处理的电导率(EC)在堆肥结束时均低于其他三个处理,而pH值则最高.四个处理的阳离子交换量(CEC)均呈持续增大趋势,至堆肥结束时分别为115.3、150.5、125.4和95.2 cmol·kg-1.堆肥结束时处理A、B、C和D的发芽指数(GI)分别为77.5%、113.2%、92.2%和62.5%.结果表明,处理B最适于烟草废弃物堆肥.
Aiming at studying effects of different aeration rates of 0. 1 0. 2 0. 3 and 0.4 ms 3 ·h^-1·m^-3 compostmg volume, corresponding to pile A, pile B, pile C and pile D on physicoehemical properties and seed germination in- dex of tobacco waste composting were researched. The temperature exceeding 55 ℃ in pile A, pile B and pile C re- mained more than three consecutive days, but only 1 day was above 55 ℃ in pile D. The final electrical conductivi- ty(EC) of pile B were lower than the other three piles, but pH value was higher. Exchange capacity (CEC) showed a growing trend in all piles, and the final CEC were 115. 3, 150.5, 125.4 and 95.2 cmol.kg, respective- ly. The final germination index (GI) for pile A, pile B, pile C and pile D was 77.5% , 113.2% , 92. 2% and 62.5%, respectively. The results showed that pile B was most suitable for tobacco waste compost.
