稻茬田不同模式蚕豆栽培技术研究

Study on Cultivation Techniques of Different Modes of Broad Bean in Rice Stubble Field

为探索稻茬田蚕豆高效栽培模式,在稻茬田中开展蚕豆4种不同栽培模式试验研究,对不同模式蚕豆主要性状及经济效益进行分析。试验结果表明,以浸种催芽后,对露白萌动期的蚕豆种子进行春化处理后直播为最宜。该模式比轮作直播蚕豆667 m^(2)增效1600.8元,比轮作小麦增效1734.8元。晚稻—蚕豆种子春化模式不仅可提高种粮农户的经济收入,还能有效缓解作物的连作障碍,减轻稻田杂草稻的发生,提升土壤肥力等。

In order to explore the efficient cultivation mode of broad bean in rice stubble field,four different cultivation modes of broad bean were studied in rice stubble field,and the main characters and economic benefits of different modes of broad bean were analyzed.The results showed that it was the most suitable for direct seeding after vernalization treatment of broad bean seeds at the stage of white germination after soaking and germination.This mode increased by 1600.8 yuan per 667 m^(2) than that of direct-seeded broad bean and 1734.8 yuan per 667 m^(2) than that of wheat.The late rice-broad bean seed vernalization mode could not only improve the economic income of grain farmers,but also effectively alleviate the continuous cropping obstacles of crops,reduce the occurrence of weedy in paddy fields and improve soil fertility.
