采用田间试验的方法,研究了高碳基肥料对舞阳烟区土壤肥力、微生物特性、初烤烟叶化学性质以及香气物质含量的影响。结果表明:高碳基肥料在移栽后30 d,显著提高土壤碱解氮、速效磷含量,具体分别表现为:T_4>T_2>T_1>T_3>CK,T_2>T_1>T_4>T_3>CK;在移栽后45 d,高碳基肥料能够增加土壤中细菌和放线菌含量,分别以T_2和T_1处理最高;移栽后120 d施用高碳基肥料土壤中真菌数量均高于对照,以T_4处理最高;与对照相比,各处理烤后烟叶钾含量分别提高13.1%、15.9%、19.6%、9.3%,氯含量分别降低40.7%、42.6%、3.7%、14.8%;高碳基肥料可以增加烤烟中苯甲醇、苯乙醇、苯甲醛、苯乙醛、巨豆三烯酮等重要致香物质含量。
Field experiments were conducted to study the effects of high-carbon-based fertilizers on soil fertility, microbial characteristics, chemical properties of flue-cured tobacco leaf and the content of aroma components in Wuyang tobacco-growing areas. The results showed that high carbon - based fertilizers significantly increased soil available nitrogen and available phosphorus at 30 d after transplanting. The specific contents were as follows: T 4> T 2> T 1> T 3> CK, T 2> T 1> T 4> T 3> CK; At 45 days after transplanting, high-carbon based fertilizers could increase the contents of bacteria and actinomycetes in soil, which were the highest in T 2 and T 1, respectively. The numbers of fungi in high carbon-based fertilizers 120 days after transplanting were higher than those in control Compared with the control, the content of potassium increased by 13.1%, 15.9%, 19.6%, 9.3% and 40.7%, 42.6%, 3.7% and 14.8% Can increase the content of benzene, alcohol, phenylethyl alcohol, benzaldehyde, phenylacetaldehyde, megastigmatrienone and other important aroma components in flue-cured tobacco.
