Poria cocos Soil-transfer Cultivation Experiment and Its Impact on Yield

Abstract. Poria cocos is a kind of valuable Chinese herbal medicine. It has great health care and medicinal value and is widely used in anti-fatigue, anti-tumor and immunity improvement fields. However, the planting of Poria cocos is limited by environment because it requires mountainous region and sandy soil. This paper creatively puts forward soil-transfer cultivation in flat land. The experiment shows there is no significant difference about yield per unit area between soil-transfer cultivation and traditional slope cultivation (about 31000 kg/ha). But the sclerotia forming ratio of soil-transfer cultivation is lower than the traditional (81.1% and 91.0% respectively). That means the Poria cocos in experimental land would grow better in size. The consequence indicates that the difference about yield of two cultivation methods could omit. But from environment protection aspects, soil-transfer cultivation has profound significance.
