摘要
作者于1982—1987年,研究了温度、光照和湿度对甘薯“高自1号”开花的影响.重庆地区以7—9月为盛花期.开花的最适温度为22—28℃;适合开花的土温为23—27℃;开花的最适相对湿度为80%—95%;适宜开花的土壤含水量为20%—25%,土壤含水量大于28%或小于19%,开花数减少.甘薯“高自1号”属光周期不敏感型,光照长短与开花数之间的规律性不明显.
This research has been carried on for five years from 1982 to 1987. The results are given bellow:1. In Chongqing region, Sichuan province, the luxuriant flowering season is from July to September. The optimum atmospheric temperature is 22-28C, the highest being 35C and the lowest being about 12C. The suitable soil temperature for flowering is 23-27C- As the soil temperature is more stable than the air temperature, it is a favorable condition for Sweet potatos to flower.2. The optimum air humidity for flowering is 80%-95%, if it is more or less, the flowering numbers and quality will be affected. The optimum water content in the soil flowering is 20%-25%; if it is more than 28% or less than 19%, the flowering numbers will decrease,3. The sweet potato cultigen, 'Gaozi No. l' used in the experiment is insensitive to the cycle of illumination, but it can naturally be in blossom each year in the region concerned.
