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(NH+4)和硝态氮(NO-3)对烤烟的农艺性状、生理生化指标和产量品质的影响。
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% NH + 4-N+50% NO - 3-N under the soil and weather condition in Yunnan province.
