摘  要：
为了了解曲靖烟区土壤养分状况,对采集的曲靖烟区3716个土样进行了养分状况分析,结果表明:土壤pH值平均为6.27,有机质含量3.7%,碱解氮、有效磷、速效钾含量分别为130.23、28.14、201.83 mg/kg,有效硼含量0.424 mg/kg,水溶性氯含量27.23 mg/kg。烟区有机质和碱解氮含量总体偏高;有效磷除富源县含量偏低外,其他县(市)都处于适宜或富余范围;陆良县速效钾含量偏低,建议补充钾肥;有效硼普遍缺乏。不同植烟县(市)间养分差异较大,各养分的变异程度大小顺序为水溶性氯>有效硼>速效钾>有效磷>有机质>碱解氮。因此,提出控氮、稳磷、保钾,合理增施硼肥的建议。

摘  要：
In order to know the nutrient status of tobacco-growing soils in Qujing,3 716 soil samples were collected and analyzed.The results showed that the average soil pH value was 6.27,the average contents of organic matter,available N,available P,available K,available B and available Cl were 3.7%,130.23 mg/kg,28.14 mg/kg,201.83 mg/kg,0.424 mg/kg and 27.23 mg/kg,respectively.The contents of organic matter and available N were generally high in tobacco-growing soils;except the available P in soils from Fuyuan country was low,the other counties were in the range of appropriate or rich;the available K in soils from Luliang county was low,therefore it should add K fertilizer to the soil;the available B was generally lacking in the tobacco-growing soils.Moreover,the content of soil nutrients shows significant variation at different locations,and the order of coefficient of variation(CV) was available Cl>available B> available K >available P >organic matter.Therefore,the suggestions that the tobacco-growing soils in Qujing should control N content,steady P content and K content,and add B fertilizer were proposed.
