Abstract: High quality and high yield of famous agricultural products are often related to the specific eco-geological environment and geochemical conditions of the producing area.This paper develops the eco-geological and geochemical adaptibility model of Myricarubra in Longhai City. Geological and geochemical survey for famous producing area of Fugong bayberry were conducted.Theresults show that the geological background of the high-quality bayberry producing area in Longhai is granitoid, and the values of Mn, P, S, Zn, Al₂O₃, Na₂O, K₂O and available Mn, P, S in soil are relatively high, whilethe values of heavy metal elements such as As, Cd, Cr and Hg are low. The terrain of this area is hilly and mountainous with low elevation and low slope, and soil types are mainly red and yellow soil.According to the eco-geological model and on the basis of the data of 1;50,000 soilquality geochemical survey, 1;50,000 geological map as well as topographic, geomorphic and soil type maps of Longhai City, the suitable planting area of Myricarubra in Longhai was delineated, which involve 259.89 km² optimum planting area and 70.62 km² suitable planting area,which is about 5 times the existing planting area. These results could give geological and geochemical basis for planting planningof Myricarubra in Longhai City.
