有机无机肥配施对烤烟质体色素及降解产物的影响

Effects of Combined Application of Organic and Chemical Fertilizers on Plastid Pigment and its Degraded Products in Flue-cured Tobacco

通过田间试验研究了有机无机肥不同配施比例对烤烟质体色素及其降解产物的影响。结果表明,在同一部位中,施有机肥的4个处理,叶绿素、类胡萝卜素含量比不施有机肥的都显著提高,T6(100%芝麻饼肥)处理叶绿素含量最高,T4(50%无机肥+50%芝麻饼肥)类胡萝卜素含量最高,类胡萝卜素与叶绿素比值T4最高,T6最低。在新植二烯、类胡萝卜素降解产物含量和质体色素降解产物总量方面,除T5(25%无机肥+75%芝麻饼肥)的中部叶以外,所有施用有机肥的处理在各部位中三者均有不同程度的增加,其中下部叶分别是T3(75%无机肥+25%芝麻饼肥)、T4最高;中、上部叶中T4的最高。因此,50%无机肥+50%芝麻饼肥对烤烟质体色素及其降解产物含量的影响最大,尤其是上部叶。

Effects of combined application of organic and chemical fertilizers on plastid pigment and its degraded products in flue-cured tobacco was investigated with field experiments.The result shows that the contents of chlorophyll and carotenoid with the treatment of organic fertilizers were significantly（at 5% level） higher than those with no organic fertilizers treatment.Chlorophyll contents with T6 treatment（100% sesame seed cake fertilizer） and carotenoid contents with T4 treatment（50% chemical fertilizers and 50% sesame seed cake fertilizers） were the highest among all of the 6 treatments.But for the ratio between carotenoid and chlorophyll,T4 was the highest,T6 the lowest.The contents of aromatic components of the cartenoids,neophytadiene and the plastid pigment degraded products increased by varying degrees except for the cutters of T5（25% chemical fertilizers and 75% sesame seed cake fertilizers）,and the highest contents of them were T4,T3（75% chemical fertilizers and 25% sesame seed cake fertilizers）,T3 respectively in lower leaves,and always T4 among the cutters and upper leaves.Therefore,50% chemical fertilizers and 50% sesame seed cake fertilizers have the greatest effects on plastid pigment and its degraded products in flue-cured tobacco,especially in the upper leaves.
