摘要
合理施肥是烤烟栽培和优质适产的重要技术环节。本研究针对广西土壤养分供应不平衡和施肥不合理的情况，通过对大量元素和微量元素的配合使用，探索氮、磷、钾、锌对烤烟产量和品质的影响，寻求供试条件下最佳施肥方案。研究表明，供试条件下优质烤烟最佳方案为：Ｎ９７．０５ｋｇ／ｈｍ２，Ｐ２Ｏ５２１５．８５ｋｇ／ｈｍ２，Ｋ２Ｏ３３５．７０ｋｇ／ｈｍ２，Ｚｎ４．７６ｋｇ／ｈｍ２，目标产量３１７３．８５ｋｇ／ｈｍ２，产值１０１６１．６０元／ｈｍ２，均价３．２５元／ｋｇ。
Rational manuring is an important link of the tobacco cultivation and to obtain high-quality, proper-yield tobacco. The study is to indicate the effects of different rations of nitrogen (N), phosphorus (P), potassium (K) and zinc (Zn) on yield and quality of tobacco.The best fertilizer scheme was: N 97. 05 kg/hm2, P2O5 215. 85 kg/hm2. K2O 335. 70 kg/hm2.Zn 4. 76 kg/hm2, objective yield was 3 173. 85 kg/hm2, output value was 10 161. 60 yuan/hm2. average price was 3. 25 yuan/kg.
