摘要 名特优农产品的高品高产往往与产地特定的生态地质环境、地球化学条件有关。以龙海市浮宫杨梅优质产区为主要研究对象,通过实地调查与调研,建立了龙海市优质杨梅产区的生态地质、地球化学适生模型。研究表明:龙海市优质杨梅产区成土母岩为花岗岩类岩石,风化形成的土壤中Mn、P、S、Zn、Al_(2)O_(3)、Na_(2)O、K_(2)O等指标含量及Mn、P、S等有效量较高,As、Cd、Cr、Hg等重金属元素含量低;地形地貌为低海拔、低坡度的丘陵山区;土壤类型为红壤、黄壤。根据建立的模型,以龙海市1:5万土地质量地球化学调查成果、1:5万地质图、地形地貌图及土壤类型图等资料为基础,对龙海市杨梅适宜种植区进行了划定,圈出龙海市杨梅最适种植区330.51km^(2)和适宜种植区70.62 km^(2),是现有杨梅种植面积的5倍左右,为龙海市杨梅种植规划提供了地质地球化学依据。 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,Al_(2)O_(3),Na_(2)O,K_(2)O 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 km^(2)optimum planting area and 70.62 km^(2)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.
