甘薯在高温高湿条件下,茎叶生长旺盛,而块根产量往往较低。在有些地区一年内均可栽种,但在另一些地区由于块根产量低而种植甘薯并不合算。不同地区有其各自的最适栽插期,尽管已知某一地区的最佳栽插期,但却缺乏决定最佳栽插期的有关资料。本研究以积温 Sweet potato under high temperature and humidity conditions, vigorous growth of stems and leaves, and tuber yield is often low. In some areas can be planted within a year, but in other parts of the sweet potato production due to low yield is not cost-effective. Different regions have their own optimal planting period, although the best planting period in a particular area is known, but there is a lack of relevant information to determine the optimal planting period. This study uses accumulated temperature
