氮磷钾配施对烤烟农艺性状和主要化学成分的影响
EFFECT OF COMBINED APPLICATION N,P AND K FERTILIZER ON AGRONOMIC CHARACTERS AND THE MAIN CHEMICAL COMPONENTS OF FLUE-CURED TOBACCO
摘要
Abstract
Field experiments were conducted to investigate the secondary influence relationships of the effects of nitrogen, phosphorus and potassium （NPK） fertilizers on the agronomic characters and the main chemical composition, using the gray correlation analysis method, during growth and development of flue cured tobacco leaves. Results showed that agronomic characters nitrogen fertilizer with the association order of single - leaf weight 〉 leaf length 〉 leaf width 〉 plant height 〉 remained leaves; with phosphorus fertilizer, the order is the single -leaf weight 〉 plant height 〉 leaf length 〉 leaf width 〉 remained leaves; for potassium fertilizer, it followed the order of the single leaf weight 〉 leaf length 〉 plant height 〉 leaf width 〉 remained leaves. Leaf nitrogen content was closely related to phosphorus fertilizers, and leaf potassium content was closely related to potassium fertilizer. The impact of nitrogen and phosphorus were also more significant than potassium. The main factor affecting starch was phosphorus fertilizer and the main factors affection total sugar and reducing sugar content were potassium and phosphorus fertilizers, respectively. Potassium fertilizer was the main factors affecting free amino acids. Therefore, in flue - cured tobacco cultivation, a reasonable proportion of N, P and K fertilizer can effectively coordinate flue - cured tobacco agronomic characters and the content of main chemical components, which in turn provide basis for high yield and quality of flue - cured tobacco.关键词
