不同饼肥配施对烤烟干物质积累及质体色素含量的影响

Combined Application of Cake Fertilizers Affects Dry Matter Accumulation and Plastid Pigment Content of Flue-cured Tobacco

选用豆粕、菜粕、芝麻粕3种饼肥组合发酵作为试验材料,采用盆栽试验的方法探讨不同饼肥组合处理对烟株生长、干物质积累及质体色素含量影响。结果表明,施用饼肥处理的各项指标均优于施用纯化肥处理,显著增强了烟株生长势,提高了烟叶干物质量积累、叶绿素、类胡萝卜素含量;有机肥施用可明显提高烤烟香气前提物质,增加烤烟香气物质含量。不同饼肥配施处理对烤烟的农艺性状、干物质量、氮磷钾积累及叶绿素总量、类胡萝卜素含量影响差异显著,饼肥组合4的烤烟香气物效果最优,建议在烤烟栽培施肥中推广应用该饼肥组合。

The experiment aims to identify the application effects of cake fertilizers on growth, dry matteraccumulation, plastid pigment of flue-cured tobacco. The results showed that all indexes of tobacco in differentcake fertilizer treatments were better than those of CK, and cake fertilizer application significantly enhancedthe growth potential of flue-cured tobacco, increased dry matter accumulation and plastid pigment content intobacco leaves in pot experiments. The application of organic fertilizer could significantly improve the aromapremise material of flue-cured tobacco to increase the content of aroma substance. In addition, different cakefertilizer treatments showed different influences on the agronomic traits, dry matter accumulation, contents ofnitrogen, phosphorus, and potassium, total chlorophyll and carotenoid content of flue-cured tobacco, and thebest effects was found in combination 4 which could significantly increase the content of aroma material and beapplied the cultivation and fertilization of flue-cured tobacco.
