The invention discloses a dioscorea zingiberensis cultivation method in a high attitude area, and belongs to the technical field of traditional Chinese medicinal material cultivation. In order to solve the problems that when dioscorea zingiberensis is cultivated in the high attitude area, the adversity resistance is poor, the seed germination rate is low, the yield is low, and the diosgenin content is low, the dioscorea zingiberensis cultivation method in the high attitude area is provided, and various needed nutrient substances are provided for growth of the dioscorea zingiberensis in the high attitude area through the steps of seed pretreatment, sufficient application of base fertilizer and reasonable topdressing; the adversity resistance of the dioscorea zingiberensis in the high attitude area is enhanced, the seed germination rate of the dioscorea zingiberensis is increased, and the yield of the dioscorea zingiberensis and the diosgenin content are significantly increased.

The invention discloses a method for improving saponin yield by low-acid pretreatment of dioscorea composita. The method comprises the steps of pretreating dioscorea composita with low-concentration sulfuric acid, carrying out solid-liquid separation, and hydrolyzing diosgenin in a solid phase part. The problems of long pretreatment period of natural fermentation and potential risk of generating impurities are avoided; meanwhile, in a process of direct hydrolysis of the diosgenin, because starch and lignocellulose are hydrolyzed and further dehydrated, the content of organic matters in the hydrolyzed waste acid water is sharply increased, and serious environmental pollution problems are caused; and in addition, the hydrolysis yield of the diosgenin is obviously improved. The method has obvious advantages and good popularization and application values.
