南充地区秋季气候资源丰富,近几年由于推广良种良法,再生稻由零星试种到区域性种植获得成功,预示着新耕作制度的出现,这是开发秋季气候资源的一项重大突破。本文以大量数据阐述发展再生稻的生产潜力,分析了再生稻的生态气候适应性,指出伏旱高温和秋季低温冷害是发展再生稻的两个不利气象条件,并将全区划分为适宜、比较适宜和不适宜3个区,提出了相应的技术措施,为趋利避害发展再生稻提供了气象科学依据。
In autumn, Nanchong has abundant climate resources in autumn. In recent years, the successful cultivation of ratooning rice from sporadic planting to regional planting has shown the success of the new farming system. This is a major breakthrough in the development of climate resources in autumn. In this paper, a large amount of data is elaborated to develop the potential of ratoon rice. The ecological adaptability of ratoon rice is analyzed. It is pointed out that the two unfavorable meteorological conditions for developing ratoon rice are the hot summer drought and low temperature cold damage in autumn. And unsuitable for the three districts, put forward the corresponding technical measures to provide meteorological science basis for the development of the recuperation rice with the trend of avoiding disadvantages.
