Abstract: 【Objective】To disscus the effects of different cultivation technique measures on yield-related traits of red sprout clocasia escalenta in Longyan fujian to provide scientific basis for high-yield cultivation of red sprout clocasia escalenta in Longyan fujian .【Methods】Using red sprout clocasia escalenta in Longyan fujian as the materials to observe the trials of different fertilizer, planting density, covering ways, variety comparison and expansion period of clocasia escalenta.【Results】Basic fertilizer (organic fertilizer 500kg/667m2) add medium-term (organic fertilizer 500kg/667m2) facilitates favor to high-yield with the best conprehensive quality;density（40cm×60cm）with the highest yield; plastic mulching can significantly increase plant height, leaf width, leaf length, mature leaves, basal culm thickness, the first grade cormels weight and the second grade cormels weight; the first grade cormels of red sprout clocasia escalenta weight and yield had the obvious phenomenon of rapid growth in the medium expansion period of clocasia escalenta (July 14); an appropriate increase in plant height and stem yield was conducive to the increase in corn yield, the increase in corn yield favor to the first grade cormel numbers, the first grade cormel yield, the second grade cormel numbers, the second grade cormel yield, and thus obtain a higher yield.【Conclusion】Integrated cultivation techniques can significantly increase red sprout clocasia escalenta yield and quality in Longyan.
