我省江准之间及皖南宣郎广波状平原上的各种中低产土壤大多是由下属系黄土母质发育而成，面积较大，分布较广。土壤的最大特点是质地粘重，耕性不良，有机质和有效养分含量不高，肥力水平低下。在进行产业结构调整时，首先必须对中低产土壤进行改良。现结合我县江淮分水岭治理 Jiangzuo between our province and southern Guangxi Xuan Lang broad undulating plains on the soil in most of the low-yielding loess parentage is developed by the Department, larger, more widely distributed. The most prominent feature of the soil is sticky texture, poor tillage, organic matter and effective nutrient content is not high, fertility levels are low. In the adjustment of industrial structure, we must first of middle and low yield soil improvement. Now combined with the county JAC watershed management
