氮磷钾配施对填充型烤烟还原糖含量的影响
Effect of N, P and K Fertilizer Combined Application on Reducing Sugar Content of Filling Flue-cured Tobacco
摘要
Abstract
Taking filled flue-cured tobacco ( Nicotiana tobacum L. ) variety of Northeast China Longjiang 911 as test material, the regression effect models on nitrogen, phosphorus and potassium (NPK) fertilizers and reducing sug ar content flue-cured tobacco was established by orthogonal regression experiment in field, and the various factors and interactions in models were analyzed. The NPK fertilization scheme to optimization of reducing sugar content was calculated. Results by the model analysis showed that reducing sugar contents flue-cured tobacco increased first and then decreased along with nitrogen increase;phosphorus increase,reducing sugar declined,and reducing sugar con tents showed a sharp decline with the increase of potassium. The two-factor effects of NKP were in order of PK > NK > NP. Value within a certain that phosphorus and potassium, nitrogen and potassium showed positive correlation with reducing sugar content, that exist promote effects; but antagonistic effects on reducing sugar content existed be tween nitrogen and phosphorus. By comprehensive analysis on fertilizer model of reducing sugar contents in the leav es of the flue-cured tobacco and NPK fertilizers, application rates of proposed fertilizers in tobacco production of warp soil was nitrogen fertilizer 24. 9 -65. 1 kg/ha,phosphorus fertilizerl3. 1 -61. 1 kg/ha and potassium fertilizer 62.1 - 194.4 kg/ha.关键词
