摘要:

赤霉素发酵滤渣(GFRs)是赤霉素生产过程中产生的固体废物,有效利用这些废物具有显著的环境效益。本文以赤霉素发酵滤渣为原料,分别添加10%、20%、30%和40%的姜末作为辅料进行好氧堆肥,以探究最佳的姜末添加量。结果表明, 当添加30% 姜末作为辅料时, 发酵滤渣的好氧堆肥效果较好, 高温期持续时间较长且达到无害化标准。同时,堆肥结束时,该处理下的种子发芽指数最高,达到60%以上。此外,该处理下的全钾含量增加了2.97百分点,高温期内的水溶性碳含量降低了1.48百分点, 均有利于促进堆肥的腐熟。因此,本研究认为添加30%的姜末作为辅料更适合赤霉素发酵滤渣的好氧堆肥。结合赤霉素含量和种子发芽指数的变化情况,本研究建议可以适当延长堆肥时间以确保赤霉素完全降解,并使种子发芽指数达到NY/T525—2021《有机肥料》的要求。

Abstract:

Gibberellin fermentation residues (GFRs) are solid waste generated during the production of gibberellin. Effectively utilizing this waste has significant environmental benefits. In this paper, the GFRs were used as the raw material, and 10%, 20%, 30% and 40% of ginger powder were added as auxiliary materials respectively for aerobic composting to explore the optimal addition amount of ginger powder. The results indicated that when 30% ginger powder was added as an auxiliary material, the aerobic composting effect of the fermented residue was improved, with a prolonged high-temperature period that met the sanitization standard. Meanwhile, at the end of the composting process, the seed germination index under this treatment reached the highest value, exceeding 60%. Additionally, the total potassium content under this treatment increased by 2.97 percentage points, while the water-soluble carbon content during the high-temperature period decreased by 1.48 percentage points, both of which contributed to promoting the maturation of the compost. Therefore, adding 30% ginger powder as an auxiliary material was more suitable for aerobic composting of GFRs. Regarding the changes in gibberellin content and germination index, it is recommended to extend the composting period to ensure the complete degradation of gibberellin and compliance with the standard for germination index of NY 525—2021 Organic fertilizer.
