摘要
甘薯很可能在明末就从缅滇陆路传入四川。清中后期,此物从滇、黔、鄂、湘、赣、闽、粤等更多路径入川,在该省很多地方,特别是丘陵、低山区广泛传播。其动因在于四川盆地较好的自然与交通条件,快速增长的人口,尤其是农家对甘薯特性的科学认识、对其生产技术的系统把握。清代,甘薯在四川的传播促进了土地的开发利用,提高了粮食生产水平,引起种植结构与民食结构的变化,增强了救荒能力,丰富了农业文化;此外,它还推动了畜牧业发展,增加了商品粮供给,有助于保持水土,为后世奠定了栽培技术基础,而且四川一些甘薯品种还传播到外省。总之,其影响是多方面的,且主要是积极的。
It was much probably that sweet potato was introduced into Sichuan province from the land route of Burma and Yunnan during the late Ming dynasty. In the mid - late Qing dynasty, this kind of crop had spread widely from more channels as Yunnan, Guizhou, Hubei, Hunan, Jiangxi, Fujian and Guangdong, etc. to many places of this province, especially to the hilly land and low mountain areas. The causes lay in the relatively good conditions of nature and communications and the fast increasing population, particularly the farmers scientific recognition of sweet potato and their systematic knowledge of its production technology. In the Qing dynasty, sweet potato promoted Sichuan land reclamation and utili- zation, raised the grain production level, gave rise to the change of planting and food structures, strengthened the ability to relieve disasters and enriched the local agriculture; besides, it pushed forward husbandry development, raised the provision of commodity grain, helped soil maintenance and set up some planting technological bases for the coming generations. In addition, some kinds of sweet potato also spread from Sichuan to other provinces. Briefly speaking, its influence was many-sided and mainly positive.
