| 摘 要： | 目的]研究周口主要植烟土壤养分状况,为烟田合理施肥提供依据。方法]2009年在周口烟区商水、鹿邑、郸城等植烟县市采集有代表性烟田土壤样品,分析其有机质、速效氮、速效磷、速效钾等养分含量。结果]全区土壤有机质和碱解氮含量相对偏高,速效磷总体含量集中在＂中低＂水平,速效钾含量较丰富,水溶性氯含量偏高,有效硼普遍缺乏。4个重点植烟县烟田土壤养分状况存在差异。结论]该区烤烟施肥应遵循＂控氮,增磷,稳钾,补硼、锰微肥＂的施肥原则。

| Abstract: | Objective] The research aimed to provide scientific reference for reasonable fertilizer application of flue-cured tobacco and study the nutrients of tobacco growing soils in Zhoukou.Method] From analyzing the soil of representative samplings in tobacco growing area of Shangshui,Luyi,Dancheng County,the content of organic matter,alkali-hydro nitrogen,available P and K were analyzed.Result] The results indicated that organic matter and available N was high,available P was low in most soil and available K was rich,contents of soluble chloride was high,while available boron was deficiency.Moreover,difference existed among nutrient element of four counties.Conclusion] The fertilization principle of of controlling nitrogen,increasing phosphorus,stabilizing potassium,increasing calcium boron and manganese in tobacco production was proposed. |
