The invention provides a low-altitude cultivation method for polygonum viviparum. The problem that the polygonum viviparum cannot be cultivated under low-altitude condition is solved by adopting the means of formulated fat ball and shed house temperature control. Meanwhile, the polygonum viviparum cultivated by the method has the characteristics of high glucose, high ash content and high K, and also has the characteristics that arginine serves as a main component and glutamic acid, histidine and aspartic acid serve as auxiliary components on the basis of multiple amino acids.
