摘要
通过田间试验,研究了有机肥与无机肥不同比例配施对烤烟脂类代谢的影响。试验结果表明,配施有机肥提高了烤烟生长后期烟叶的脂氧合酶活性,增强了烟叶生长后期的脂类代谢。同时,配施适量有机肥提高了烟叶生长后期的饱和脂肪酸、类胡萝卜素、乙醚提取物含量和成熟期的腺毛密度、腺毛分泌物含量,并降低不饱和脂肪酸的含量。烘烤后以配施30%有机肥处理烟叶的总饱和脂肪酸含量最高,总不饱和脂肪酸含量最低,有利于烟叶品质的提高。
This experiment studied the effect of organic fertilizer combined with chemical fertilizer on flue-cured tobacco lipid metabolism by different ratio treatment with field Trial. The main results are showed, matching organic fertilizer increased lipoxygenase activity at later stage, which boosted up lipid metabolism. Meanwhile, matching the appropriate amounts of organic fertilizer in- creased the total content of saturated fatty acid, carotenoid, aether extract, secretion and the density of glandular trichome, and decreased the total content of unsaturated fatty acid. The treatment which matched 30% organic fertilizer contained the highest content of total saturated fatty acid and the lowest content of total ansaturated fatty acid, which was beneficial to qualities of tobacco leaves.
