Dongqianling Village is located in the northwest corner of Heya Town, about 2 kilometers away. The soil behind the village is excellent, and there has long been a saying that "the front ridge is behind, the back ridge is before, and the front and back are golden plates". The upper soil is about 30 cm yellow fertile soil, and the lower soil is sandy soil, which is rich in various trace elements beneficial to human body and is very suitable for yam growth. Therefore, the produced yam is rich in nutrition and pleasant in taste. Regular consumption also has the effects of nourishing yin and tonifying kidney, moistening lung and caring skin. It is not only a precious vegetable on the table, but also a high-quality natural tonic.
In the past, some large households in Jiaodong area sold out in advance before Qianlingshan medicine went on the market. They are also very particular about eating. One is to put yam in a pot, add appropriate amount of water, boil it with slow fire first, and then cook it with slow fire for a while. After boiling, there is little water left. The boiled yam skin is slightly cracked (that is, people often say "opening sand"). The peeled yam meat is white, huge, soft and delicate, and then dipped in white sugar, which is sweet and delicious and refreshing. Sometimes made into balls and dried, they can be preserved for a long time. Occasionally take out a few pieces and brew them in a cup, which has a special taste. The second is to make yam. Drawn yam made from Qianling Mountain medicine has a unique taste and taste. Nowadays, as a kind of home cooking, yam is eaten in many ways, all because of its high nutritional value, which makes people never tire of eating it. Until now, some elderly people in Qingdao market must name Gaomi as "Qianling Mountain Medicine" when buying yam.
Since the reform and opening up, the value of drugs in Qianling Mountain has doubled, the planting scale has been expanding and the quality has been getting better and better. Heya Town Government established "Heya Town Yam Wholesale Market", which made Qianling Mountain medicine form a brand advantage, which not only expanded the sales of yam, but also increased the income of growers. In this way, Ganling Yam evolved into "Heya Yam". Now, the town government is also preparing to set up a "Yam Planting Development Research Association" in Dongqianling Village, so as to deeply study yam planting techniques, improve yam quality, make suggestions for expanding market scale and increasing farmers' income, and make the brand of Heya Qianling Yam more resounding.
