泸州市是四川省双季稻的主要产区,常年种植面积占全省50％以上,近年来种植面积大幅度下降。双季晚稻最大的问题是晚稻产量低而不稳。究其原因,除受人为因素影响外,很大程度上还受气候条件的制约。本文试图通过对气候条件与双季晚稻产量关系的分析,为制定双季晚稻的高产稳产栽培技术提供科学依据,以促进泸州市乃至全省双季稻的恢复和发展。 Luzhou is the main producing area of ​​double cropping rice in Sichuan Province. Its perennial planting area accounts for over 50% of the province’s total area. In recent years, its acreage has dropped dramatically. The biggest problem with double crop late rice is the low and unstable yield of late rice. The reason, in addition to being affected by human factors, but also to a large extent by the climatic conditions. This article attempts to provide a scientific basis for the development of double-cropping late-season high-yielding and stable cultivation techniques by analyzing the relationship between climatic conditions and the yield of double-season late rice so as to promote the recovery and development of double-cropped rice in Luzhou and even the whole province.
