The result indicated that suitable thickness of paddy soil is about 15cm,and for dry arable land it should not be lower than 20cm;The alluvial rivers parent material is the best one to influent the output,the rice fields is the worst with the parent material of slate ground,while the dry and plough land is the worst for its purple sand shale parent material;The paddy rice is best with the acid soil,and the dry crop is the best with the neutral soil;The obstacles horizon exist in 35.2%of the rice fields in research region,and many for middle or top digit obstacles.

结果表明，水稻土的适宜耕层厚度为15 cm左右，旱耕地适宜耕层厚度应不低于20cm；成土母质对产量的影响以河湖沉积物母质最好，稻田以板页岩母质最差，旱耕地以紫色砂页岩母质最差；水稻以酸性土最好，旱作以中性土最好；研究区稻田有35.2%的存在障碍层，且多为中、高位障碍，是影响水稻产量整体提高的主要因素；水稻和旱作都以壤土为最好，其中，稻作怕砂，旱作怕粘；水稻土适宜的容重为1.00—1.29 g/cm~3。
