对济源市烤烟主产区(邵原,王屋,下冶和大峪)植烟土壤的肥力特征进行了分析,取样地点覆盖全市各主要植烟村土壤.结果表明,济源是河南潜在的优质烟区之一,其土壤肥力特征如下:烟区土壤总氮、碱解氮、速效磷、有机质含量较适宜;速效钾含量则比较丰富,在豫西乃至河南烟区都处于较高水平;水溶性氯含量均在合理范围.需要注意的问题,主要是个别烟区的微量元素有效锌、有效硼含量含量较低.根据济源烟区土壤肥力特征,提出了"稳氮、增磷、稳钾,普施硼肥和部分补锌肥"的烤烟施肥改进措施.

Soil fertility properties of the main tobacco growing area in Jiyuan (Shaoyuan, Wangwu, Xiaye and Daiyu) in west Henan Province were analyzed. Results showed that Jiyuan was one of the potential areas which could produce tobacco leaves with high quality. Its main properties of soli fertility were as follows: the content of total nitrogen, alkali-hydrolysable nitrogen, olsen-phosphorus and organic matters were suitable for high-quality tobacco production; especially, all the flue-cured tobacco growing areas in Henan Province were rich in available potassium; besides, the concentrate of water soluble chloride ion was at reasonable level. The problem was that the micro-elements such as Zn-DTPA and available boron content were at a low level in individual areas. Based on this survey, the recommendations for fertilization in Jiyuan such as stabilizing nitrogen rate, increasing phosphorus, stabilizing potassium, and applying boron commonly and supplementing zinc for the deficient soils were put forward.
