摘要/Abstract

摘要：

科学评价隆林植烟区土壤养分丰缺现状,为烟草科学种植、合理施肥提供参考依据。采用数学统计法描述隆林植烟土壤养分含量以及养分含量丰缺状况。结果表明,隆林植烟区土壤pH值、全氮适宜性较好,土壤有机质、有效硫、速效钾、有效磷,交换性镁适宜性较低,土壤活性氯、有效硼、交换性钙适宜性较高。对植烟区土壤进行养分含量丰缺评价,在生产中遵循控氮、控磷、控氯、控钙、提钾、增硫、补镁、增硼,减少碱性肥料的大量施用,多施重施有机肥的施肥策略,以实现烟叶绿色、优质、生态、特色、安全生产的目标。

Abstract:

The paper aims to evaluate the status of soil nutrient abundance in tobacco planting areas in Longlin, and provide reference for tobacco planting and rational fertilization. The Longlin tobacco-growing area was used as the evaluation unit, and the mathematical statistics were adopted to study the nutrient content and nutrient abundance status of the tobacco soil. The results showed that the soil pH value and total nitrogen were relatively good in the tobacco-growing area of Longlin, soil organic matter, available sulfur, available potassium, available phosphorus, exchangeable magnesium were less appropriate, soil active chlorine, available boron, exchangeable calcium had high suitability. The soil nutrient content in the tobacco-growing area was evaluated for abundance and deficiency, and the results indicated that in the process of tobacco planting, scientific fertilization should be carried out, to control nitrogen, phosphorus, chlorine and calcium, increase potassium, sulfur, magnesium and boron, and reduce the large-scale application of alkaline fertilizers, with more application of organic fertilizers, to achieve the goal of organic, high quality, ecological, characteristic and safe production of tobacco leaves.

Key words: Longlin, tobacco, soil nutrient, abundance evaluation, soil fertility evaluation
