摘要
本研究采用人工和机械两种方法对洋葱的贮藏性进行了研究。此外,我们还模拟了机械收获过程中洋葱对洋葱的冲击,并研究了对洋葱进行人工冲击处理后的贮藏性。洋葱采收方式包括手采+人工采收、挖掘机+人工采收、挖掘机+机械采收。机械采收过程中最大冲击高度为0.5 m。采收后即刻,不同采收方式的擦伤率和创面率无显著差异。由于机械采收而增加的挫伤或伤口率被认为是受土壤条件(如砾石的存在)和机器操作因素的影响。在8.5个月的贮藏期内,不同采收方式的贮藏性差异不显著。在模拟机械采收过程中冲击的处理中,冲击高度分别为0.0 m (0.0 J)、0.25 m (0.86 J)、0.5 m (1.72 J)和0.75 m (2.57 J),各冲击1次,同一位置(3.43 J)冲击4次,0.25 m位置不同位置(3.43 J)冲击4次。在8.5个月的贮藏期内,各处理的贮藏性无显著差异。
Effects of impact by mechanical harvesting on storability of onions (Allium cepa L.)
This study investigated the storability of onions according to manual and mechanical harvesting. Moreover, we simulated the onion-to-onion impact during the mechanical harvesting process and investigated the storability after artificially subjecting the onions to impact treatment. The onion harvesting methods included hand plucking + manual collection, digger + manual, and digger + mechanical collection. The maximum impact height during the mechanical harvesting process was 0.5 m. Immediately after harvesting, no significant difference in the bruise and wound rate among the harvesting methods was observed. Any increased bruise or wound rate because of mechanical harvesting was presumed to be influenced by soil conditions, such as the presence of gravel, and machine operation factors. Furthermore, the storability during the 8.5 months storage showed no significant difference according to the harvesting methods. In treatments by simulating the impacts during the mechanical harvesting process, the impact heights were 0.0 m (0.0 J), 0.25 m (0.86 J), 0.5 m (1.72 J), and 0.75 m (2.57 J), each performed once, and four times at the same position (3.43 J) and four times at different positions (3.43 J) at 0.25 m. Throughout all the treatments, there were no significant differences in the storability during the 8.5 months storage period.
