Effect of Organic Manure Application on Flue-cured Tobacco Root Development and Leaf Quality
-
摘要: 在同一施無機肥水平條件下,，研究了增施腐熟有機肥對烤煙根系發(fā)育及品質的影響,。結果表明，有機肥可促進烤煙一級,、二級側根的發(fā)生發(fā)育,；各處理一級、二級側根的體積,、干重隨烤煙生育期的延伸而增加,，但施有機肥的處理增加幅度明顯大于對照。同一時期,，一級與二級側根施有機肥處理的長度,、數量、體積及干重明顯大于對照,，根系活力也明顯大于對照,。施有機肥處理B2F 煙葉的總糖、還原糖含量低于對照,，總氮,、煙堿、蛋白質含量高于對照,；C2F 煙葉的總糖,、還原糖含量、評吸總分均高于對照,；X2F 煙葉的煙堿,、鉀含量均高于對照。Abstract: With the same inorganic fertilizer rates, effects of applying fully-fermented organic manure on flue-cured tobacco root development and leaf quality were studied. The results indicated that organic manure could enhance the development of the flue-cured tobacco's first and second order lateral roots. The volume and dry mass of the first and second order lateral root increased with the increase of growth period and the increasing range in organic manure treatments was bigger than that of control. Compared with the control, applying organic manure could improve the length, amount, volume and dry mass of the first and second order lateral root and root vigor. It could also reduce the contents of total sugar and reducing sugar, yet increase the contents of total nitrogen, nicotine and protein in B2F. It could increase the contents of total sugar and reducing sugar in C2F and nicotine and potassium in X2F. The scores of aroma volume, after taste, offensive odor, lingering odor scores and the total score of sensory quality of C2F were higher than that of control.
