摘要:
为了研究蓝藻与农业废弃物无害化处理及资源化利用技术，开展蓝藻、菌渣、稻壳混合富硒堆肥试验，设置对照组（CK）、富硒枯草芽孢杆菌组（W）、亚硒酸钠组（Y）研究不同硒处理对蓝藻好氧堆肥的影响。结果表明，堆制48 d后，各处理的堆肥均已满足有机肥料国家标准（NY 525-2012《有机肥料》）的要求，pH值均维持在5.5～8.5，种子发芽指数均高于85.00%，W处理组的有机质含量分别较CK、Y处理组提高了8.72%、9.13%，总养分（N+P2O5+K2O）含量分别较CK、Y处理组提高了5.60%、4.70%，总硒含量分别较CK、Y处理组提高了1.92倍、0.21倍。盆栽试验结果表明，W、Y处理组的普通白菜株高、根长、单株鲜质量均显著高于对照组（P<0.05），与对照组相比，W、Y处理组的总硒含量分别提高了127.73%、112.53%，有机硒含量分别提高了135.45%、102.73%，此外，施加硒肥减少了普通白菜体内铅、镉的累积量。综合考虑2种硒处理对蓝藻堆肥的影响得出，富硒枯草芽孢杆菌处理的堆肥效果相对更好。
Abstract:
To study the technology of harmless treatment and resource utilization of cyanobacteria and agricultural wastes, experiment of selenium enriched composting using mixture of cyanobacteria, mushroom residue and rice husk was carried out. Groups of control (CK), selenium-enriched Bacillus subtilis (W) and sodium selenite (Y) were set up to study the effects of different selenium treatments on cyanobacteria aerobic composting. The results showed that, after 48 days of composting, the finished compost of each treatment met the requirements of the national standard for organic fertilizer (NY 525-2012 ). The pH was maintained at 5.5-8.5, and the seed germination index was higher than 85.00%. The organic matter content of W treatment group increased by 8.72% and 9.13% compared with CK and Y treatments respectively, the total nutrients (N+P2O5+K2O) content increased by 5.60% and 4.70% compared with CK and Y treatment groups respectively, and the total selenium content increased by 1.92 times and 0.21 time compared with CK and Y treatment groups respectively. The pot experiment results showed that the plant height, root length and fresh weight of single bok choy plant in W and Y treatment groups were significantly higher than those of the control group (P<0.05). Compared with the control group, the total selenium content of W and Y treatment groups increased by 127.73% and 112.53%, the organic selenium content also increased by 135.45% and 102.73% respectively, and the application of selenium fertilizer reduced the accumulation of lead and cadmium in the bok choy. Considering the effects of two selenium treatments on cyanobacteria composting, the composting effect of selenium-enriched B. subtilis treatment is relatively better.
