田菁(田菁属 SesbaniaPetSoon)原产亚热带,在我国最初栽培在南方广东、福建等省,晚近经引种、驯化,逐渐推移至北方。由于其耐盐、耐涝、高产,目前已成为我国栽培面积较大的绿肥作物。在工业上田菁亦有广泛的用途,如田菁胶粉可作为开采石油的压裂液。田菁在我地区引种种植初期,收不到成熟种子,给大面积推广应用带来了困难。为了解决生产留种问题,深入探索田菁生长发育与环境的关系,特别是对田菁光周期反应的研究,无论在理论和实践上均具有重要意义。 SesbaniaPetSoon (SesbaniaPetSoon) native to the subtropical, initially cultivated in southern China in Guangdong, Fujian and other provinces, recently introduced, domesticated, and gradually moved to the north. Due to its salt tolerance, waterlogging resistance and high yield, it has become a large green manure crop in China. In the industrial field of cyanine also has a wide range of uses, such as Sesbania powder can be used as a fracturing fluid oil exploration. Sesbania introduced in my area early planting, not mature seeds received, to promote the application of a large area has caused difficulties. In order to solve the problem of production retention, it is of great significance in theory and practice to deeply explore the relationship between the growth and development of Sesbania and the environment, especially the study on the response of Siping Jinguang.
