不同氮素形态对烤烟品质影响的研究

Effects of Applied Different Forms of N Fertilizer on Quality of Flue-cured Tobacco

摘要: 1993~1995年连续3年在云南省中等肥力的砂壤土上进行盆栽和大田小区试验,研究不同比例的铵态氮(NH₄⁺)和硝态氮(NO₃^-)对烤烟的农艺性状、生理生化指标和产量品质的影响。研究结果表明:在云南省的土壤气候条件下50% NH₄⁺-N+50% NO₃^--N是烤烟最佳的氮素形态配比。

Abstract: A field plot and pot experiments on sandy loam of middle fertility soil were conducted from 1993 to 1995.The different forms of N fertilizer effect on agronomic, physiological and biochemical characteristics, yield and quality of flue-cured tobacco were observed.The results showed that the best forms of N fertilizer is 50% NH₄⁺-N +50% NO₃^--N under the soil and weather condition in Yunnan province.
