Research on High Quality Flue-cured Tobacco Fertilization Model in Panzhihua City
摘要
Abstract
In this study,the "3414" fertilizer experiment was designed to study the ettects ot nitrogen,phosphorus and potassium fertilizers on the chemical components of flue-cured tobacco.In order to determine the high quality flue-cured tobacco fertilization model in the city of Panzhihua,the contents of nitrogen,phosphorus,potassium,chlorine,nicotine,total sugar,reducing sugar,protein,ash in middle leaves of flue-cured tobacco under different nitrogen,phosphorus and potassium fertilizer were comprehensively evaluated by analytic hierarchy process and fuzzy comprehensive evaluation.And then establish the model of fertilization.The results showed that:(1) The greatest influence of the chemical components on the flue-cured tobacco leaf quality was potassium and nicotine,the influence of total sugar and reducing sugar was the second,and chlorine,nitrogen,protein,phosphorus,ash has little influence.(2) The flue-cured chemical components in 14 different fertilization treatments were comprehensively evaluated by fuzzy comprehensive evaluation.The treatment 10 (N 120 kg/hm2,P2O5 180 kg/hm2,K2O 540 kg/hm2) got the highest score,it was the best quality.(3) By way of finding optimum solution of the fertilization models,showed that,in this experiment,when the fertilizer rates were N at (109 ± 27.36) kg/hm2,P at (202.5 ± 43.11) kg/hm2,K at (464.94±58.86) kg/hm2,the flue-cured tobacco leaf quality could be the best.关键词
