摘要:

中国稻茬油菜种植区域主要在长江流域冬油菜区,近些年来稻茬油菜的单产不断提高,种植面积也稳中有升,为中国的油料安全做出了重要贡献。然而,随着长江流域冬油菜区水稻中晚熟品种轻简化栽培技术的推广应用,水稻成熟期大幅度推迟,导致油菜冬前生长时间进一步压缩,油菜晚播与过晚播面积逐年增大,严重制约了油菜的生产潜力。在长江流域稻油两熟区,油菜晚播现象尤为突出,已成为诸多学者广泛关注的热点问题。通过对油菜晚播现状以及相关高产限制因素的分析,致力于找出晚播油菜生产中的重要问题。通过对油菜晚播现状的分析,提高稻油轮作区油菜籽粒质量和产量。提倡运用先进的栽培技术减轻油菜晚播的影响,为促进未来油菜产业的蓬勃发展提供理论参考。

Abstract:

The planting area of rice stubble rapeseed in China is mainly in the winter rapeseed area of the Yangtze River Basin. In recent years, the yield of rice stubble rapeseed has been continuously increasing, and the planting area has also steadily improved, making important contributions to the safety of oil crops in China. However, with the promotion and application of light and simplified cultivation techniques for mid to late maturing rice varieties in the winter rapeseed area of the Yangtze River Basin, the maturity period of rice has been significantly delayed, leading to further compression of the pre winter growth time of rapeseed. The area of late sowing and over late sowing of rapeseed has been increasing year by year, which seriously restricted the production potential of rapeseed. The phenomenon of late sowing of rapeseed in the rice oil dual cropping areas of the Yangtze River Basin is particularly prominent, and has become a widespread concern for many scholars. This article aims to identify important issues in late sowing rapeseed production by analyzing the current situation of late sowing rapeseed and related high-yield limiting factors. Through the analysis of the current situation of late sowing, we aim to improve the quality and yield of rapeseed in rice oil rotation areas. The use of advanced cultivation techniques can reduce the impact of late sowing of rapeseed, and provide theoretical reference for promoting the vigorous development of the future rapeseed industry.
