摘　　要：通过对全县6个土类,19 496.93 hm2耕地土壤pH值、有机质、碱解氮、有效磷、速效钾、有效硫、交换性镁、有效硼、有效锰、有效锌进行养分分析。结果表明,49.81%的土壤偏酸,37.84%的土壤有机质偏低,24.69%的土壤碱解氮缺乏,47.41%的土壤缺磷,37.25%的土壤缺钾,53.89%的土壤缺硫,25.95%的土壤缺镁,97.25%的土壤缺硼,41.77%的土壤缺锰,69.28%的土壤缺锌;根据丰缺情况,提出烤烟、甘蔗、玉米、水稻等主要栽培农作物的施肥建议,指导农户科学施肥,提高肥料利用率,确保农业增效、农民增收。Some analysis on six soils about the pH value, Organic matter, Nitrogen, available phosphorus, available potassium, effective sulfur,effective magnesium,effective boron,effective Mn, effective zinc of were conducted in the whole county with 19 496.93 hm2 farmland soils. The results showed that there were 49.81% soils with a little acid ,37.84 % soils with low organic matter, and 24.69 % soils were short of available nitrogen, 47.41% soils were short phosphorus,37.25 % soils were short of Potassium,53.89 % soils sulfur were deficiency, 25.95 % soils magnesium were deficiency, 97.25 % soils effective boron were deficiency,41.77 % soil manganese were defioiency,and 69.28 % soils zinc were deficiency. According to soil nutrient condition, we put forward to fertilize the flue-cured tobacco,sugar, maize, rice and other main crops as guiding farmers fertilization, improve the utilization rate of fertilizer to ensure agricultural efficiency and increase farmers income.
