摘  要:
为了解贵定县植烟土壤肥力状况,在4个主要种烟乡镇15个代表性种烟村(组)采集土壤,检测其理化性质。结果表明:贵定植烟土壤以酸性至微酸性土壤为主,土壤pH偏低;土壤有机质含量较丰富,20~40g/kg的土壤占93.4%;土壤全氮和碱解氮含量较丰富,主要在1.5g/kg和90mg/kg以上;土壤全磷和有效磷含量较丰富,主要在0.6g/kg和20mg/kg以上,但不同区域有效磷含量变化幅度大;土壤全钾含量偏低,主要在10g/kg以下。土壤速效钾含量丰富,主要在150mg/kg以上,但不同区域之间变化幅度较大;土壤氯离子含量适中,主要在30mg/kg以下。贵定县烟叶生产需加强土壤质量管理,增施有机肥,实行轮作,适当减少钾肥的施用,施用石灰中和改良酸性较严重的土壤。

摘  要:
In order to explore the soil fertility conditions in Guiding County,the physicochemical property was analyzed based on 15 main tobacco villages in four towns.Results:The tobacco-growing soil in Guiding was mainly acidic soil.The soil organic matter was rich,and the content in the range of 20~40g/kg accounted for 93.4%.Soil total nitrogen and available nitrogen were rich,and total nitrogen content was mainly above 1.5g/kg,and available nitrogen content was above 90mg/kg.Soil total phosphorus and available phosphorus were rich,and total phosphorus content was mainly above 0.6g/kg,and available phosphorus content was above 20 mg/kg.Soil total potassium content was mainly below 10g/kg.Soil available potassium was rich,and the content was above 150mg/kg.Soil chloride ion content was mainly below 30 mg/kg.In conclusion,it was needed to strengthen soil quality management,including application of organic fertilizer,rotation,and application of lime to improve acid soil.In addition,the use of potassium fertilizer should be reduced.
