民国时期,受江南地区特定种植制度与耕作习惯的影响,频繁发生的螟虫灾害对当地水稻生产造成了严重破坏。只是相较之下,螟虫对晚稻的破坏性要远甚于早稻。于是,为应对螟灾之为害,许多农民便纷纷改种早稻,由此促进了早稻在江南地区的推广。只是这一过程并非是完全自发进行的,很大程度上是仿效“客民”经验的结果。 During the period of the Republic of China, the frequent occurrence of stem borers and disasters caused serious damage to the local rice production, which was affected by the specific planting system and farming habits in the southern part of the Yangtze River. In contrast, stem borers are much more damaging to late rice than early rice. Thus, in response to the curse of the borer disaster, many farmers switched to early rice in succession, thus promoting the promotion of early rice in the southern region. It is only that this process is not entirely spontaneous and is largely a result of the experience of the “guest”.
