摘  要：
为了解南阳市植烟土壤养分状况,从南阳市13个县、市、区的烤烟种植区采集182个土壤样品进行养分含量测定。结果表明,南阳市植烟土壤多呈中性,较适宜;有机质含量较适宜;速效氮含量适中或丰富;速效磷中等或缺乏;速效钾含量适中或丰富;铁、锰、铜3种微量元素含量较高;钼、锌、硼3种元素普遍缺乏;氯含量大部分适宜,少部分超标。由此提出了"控氮、增磷、降钾,普遍补钼、硼,适当增锌禁氯,重视有机肥"的施肥原则。

摘  要：
In order to understand the nutrient status of tobacco-growing soils in Nanyang city,182 soil samples from flue-cured tobacco planting area in 13 counties of Nanyang were determined.The results showed that the tobacco-growing soils in Nanyang were neutral;the contents of organic matter were more appropriate;the contents of available N were appropriate or rich;the contents of available P were appropriate or lack;the contents of available K were appropriate or rich;the contents of Fe,Mn and Cu were higher;the contents of Mo,Zn and B were generally lack;the contents of Cl in most regions were appropriate,but in small regions were beyond the standard.Therefore,a fertilization principle was pointed out"controlling N amount,increasing P amount,decreasing K amount,universally supplementing Mo and B amount,properly increasing Zn amount and inhibitting Cl amount,paying attention to application of the organic fertilizer".
