马铃薯属茄科茄属,为一年生草本植物。马铃薯性喜冷凉,是喜欢低温的作物。其地下薯块形成和生长需要疏松透气、凉爽湿润的土壤环境。一般来说对温度的要求为:块茎生长的适温是16~18℃,当地温高于25℃时,块茎停止生长;茎叶生长的适温是15~25℃,超过39℃停止生长。基于此,从备种、切块、栽培地处理、施基肥、播种、田间管理和收获环节对南方马铃薯的高效栽培技术进行了说明。
Potato genus Solanaceae, an annual herb. Potato like hi cold, is like low-temperature crops. The formation and growth of underground tubers require a loose, breathable, cool, moist soil environment. In general, the temperature requirements are as follows: the suitable temperature for tuber growth is 16-18 ° C, and when the local temperature is higher than 25 ° C, the tubers stop growing; the suitable temperature for growing stems and leaves is 15-25 ° C, and the growth is stopped when the temperature exceeds 39 ° C. Based on this, efficient cultivation techniques of southern potatoes are described from the aspects of preparation, dicing, cultivation treatment, basal application, seeding, field management and harvesting.
