Effect of the addition amount of ginger powder on the aerobic composting of gibberellin fermentation residues ZHAO Tinglei, QIU Yongwei, ZHOU Ying, YAO Yanlai, HONG Chunlai, ZHU Weijing, HONG Leidong, ZHANG Tao, GUO Rui, ZHU Fengxiang Journal of Zhejiang Agricultural Sciences    2025, 66 (12): 3086-3092.   DOI: 10.16178/j.issn.0528-9017.20240909 Abstract （701）   HTML （7）    PDF （1993KB）（315）       Knowledge map    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.

In this paper, the germplasm of rootstocks, which were widely used in the watermelon and melon industry in Zhejiang Province, were used as the experimental materials. Germination indexes, seedling quality and relative values of each rootstock germplasm were measured by setting low temperature treatment at 15 ℃ and high temperature at 35 ℃, while 25 ℃ was set as a control. The results showed that low temperature treatment at 15 ℃ reduced the germination index and seedling quality of each rootstock germplasm, but there were significant differences among different germplasms. The low temperature tolerant watermelon and melon rootstock germplasm were screened out as Sizhuang 9 and Sizhuang 8, respectively. High temperature treatment at 35 ℃ reduced the germination index and seedling quality of melon rootstock germplasm, but the relative germination potential, relative germination rate and relative germination index of Sizhuang 8 were high, showing high temperature tolerance, so Sizhuang 8 was also a high temperature tolerant melon rootstock germplasm. High temperature stress only had a great effect on the germination index of watermelon rootstock Lvzhuangshi, and high temperature tolerant watermelon rootstock germplasm was selected as Sizhuang 9 and Sizhuang 10 based on the actual germination index, seedling quality and relative values.
