摘要
2022-2023 年以田间调查、电话访谈、文献查阅和专家座谈等方式对川渝地区再生稻生产情况进行了调研,统计分析了气候变化下川渝再生稻种植区生产格局变化和发展趋势,以富顺县为例,剖析了川渝地区再生稻产业发展的潜力和面临的挑战,并就如何提升再生稻气候韧性提出 5 条建议.调研显示,在气候变暖情况下,川渝地区秋季热量资源更加丰富,再生稻种植呈现适生区、优生区面积不断增加、产量稳步提高等有利变化;但气象灾害呈重发趋势,再生稻生产气候风险增高.富顺县为再生稻种植优生区,具有自然条件、技术、品种、历史、品牌、需求和政策等优势.随着再生稻产业的迅猛发展和极端天气频发重发,提高应对气候变化能力、加强再生稻气候韧性建设,对加快推进川渝地区再生稻产业发展和品牌建设具有重要的现实意义.
Abstract
A survey was conducted on the situation of the ratoon rice industry in the Sichuan-Chongqing region in 2022-2023 through field investigation,telephone interview,literature review,and expert discussion,and the change of production pattern and development trend of ratoon rice in Sichuan-Chongqing region under climate change were statistically analyzed.Taking Fushun County as an example,the development potential and challenges of ratoon rice industry in the Sichuan-Chongqing region were analyzed,and five suggestions were put forward on how to improve the climate resilience of ratoon rice.The survey showed that,the autumn heat resources in the Sichuan-Chongqing region are becoming more abundant with climate change,and the planting of ratoon rice showed favorable changes such as an increasing area of suitable and optimal growth areas,steady increase in yield.But meteorological disasters are showing a trend of recurrence,and the climate risk of ratoon rice production is increasing.Fushun County is an optimal area for planting ratoon rice,with advantages in natural conditions,technology,variety,history,brand,demand,policies,and more.With the rapid development of ratoon rice industry and frequent recurrence of extreme weather,improving the ability to respond to climate change and strengthening the construction of climate resilience of ratoon rice are of great practical significance for accelerating the development of ratoon rice industry and brand building in Sichuan-Chongqing region.
