- 摘要:
- 秸秆储存是确保秸秆沼气工程原料稳定供应的有效手段，预处理是提高秸秆沼气化利用效率的有效方法。为促进秸秆沼气化利用，以玉米秸秆为研究对象，在短期浸泡、长期厌氧两种湿法储存过程中，分别添加沼液、牛粪、菌剂进行生物预处理，对比分析玉米秸秆成分和沼气产气性能的变化。结果表明，生物预处理耦合湿法储存，能有效提高玉米秸秆产沼气性能。当短期浸泡预处理储存时，随储存时间推移，各试验组纤维素、半纤维素含量逐渐降低，TS产气率逐渐提升；其中菌剂组产沼气性能最佳，储存20 d后 TS产气率最高，达492.6 m3·t-1，比对照组高18.78%。当长期厌氧预处理储存时，各试验组纤维素、半纤维素在储存前60 d降解较快、后期降解缓慢，TS产气率呈现先升后降的趋势，其中菌剂组产沼气性能最佳，TS产气率在第60天达到最高值522.1 m3·t-1，较对照组增长60.89%；而沼液组、牛粪组TS产气率分别从第50天、第180天后低于对照组。因此，在秸秆沼气工程运行过程中，可结合实际情况选择合适的预处理储存方式，提高秸秆TS产气率。
- Abstract:
- In order to regulate the flowering period of Platycodon grandiflorum, two-year-old purple flower P. grandiflorum was used as experimental material to study the effects of pruning period and height on delayed flowering of P. grandiflorum. The results showed that after pruning at the final flowering stage, the P. grandiflorum no longer blooms. After pruning at other stages, the flowering period of P. grandiflorum was prolonged, and after pruning at the peak flowering stage, the flowering period was prolonged by up to 36 days; P. grandiflorum was no longer flowering after pruning at the end flowering stage, while the other pruning period prolonged ornamental days and the most extended days observed at pruning of florescence stage, reaching 36 days; The total flowering period of pruning at pre-bud stage and bud stage was the longest, which was 41 days; flowering for pruning height of 1/4 was first and flowering for pruning height of 1/2 was relatively late under the same pruning period. The pedicel length of pruning at pre-bud stage was significantly higher than that of control, the total number of flowers of pruning was smaller than that of control, the corolla diameter and petal length of pruning at bud, initial flowering and florescence stage were significantly higher than those of control, the petal width of pruning at initial flowering and florescence stage was significantly higher than that of control and there was no significant difference in floral traits between different pruning heights under the same pruning period.Compared to the pruning height, the pruning period is more conducive to extending the flowering period and increasing the size of the flowers.
