湖北十堰烟区不同土壤类型的肥力状况分析

[目的]评价不同土壤类型的综合肥力,为优质烟叶生产提供理论依据。[方法]对十堰烟区不同类型的植烟土壤主要养分的含量状况进行分析。[结果]十堰烟区土壤大多呈微酸性或中性,有机质含量丰富;大量元素中,碱解氮含量较高,速效钾含量普遍缺乏;水溶性氯含量偏低;微量元素中,有效铁、有效锰含量丰富,有效铜、有效钼含量适宜,有效锌含量普遍偏低。[结论]该研究对该地区烟叶的生产具有一定的指导意义,并提出了"控氮与补氮相结合,增施磷肥和钾肥,普遍补施氯肥和锌肥"的原则,为优质烟叶生产提供了良好的土壤环境。

Analysis of the Fertility Status of Different Soil Types in Shiyan Tobacco-growing Areas of Hubei Province

[Objective] The study aimed to evaluate the comprehensive soil fertility at different soil types,and it provided theoretical basis for high quality tobacco production.[Method] The content status of main nutrient in tobacco soil at different types in tobacco producing area in Shiyan Tobacco-growing Areas of Hubei province werr analyzed.[Result] The results showed that most of the soil samples in Shiyan tobacco-growing areas were from neutral to slightly acid and rich in organic matter.Among the major fertilizer elements,the content of hydrolytic N was high and the content of available K was generally lack,the content of water-soluble Cl was very low.For microelements,the contents of available Fe and available Mn were rich,the contents of available Cu and available Mo were suitable,and the content of available Zn was generally low.[Conclusion] The research had some guiding significance for tobacco production of the area.In order to supply a good soil conditions for high quality tobacco production,the principles were put forward that was combining control N and supply N,increasing P and K fertilizers,and adding Cl and Zn fertilizers in general.
