摘要
重庆市黔江烟区为高海拔多雨烟区,烟苗移栽前后气温较低,不利于其生长发育,为改善这一现状,于2022年施加含腐植酸水溶肥料的生根剂。在烟苗移栽后分为4个浓度处理:CK(0 mg/L)、T1(60 mg/L)、T2(90 mg/L)、T3(120 mg/L),灌根喷施,每个小区按照T1、T2、T3处理的浓度施加50 L;并从农艺性状、初烤烟叶的外观质量、化学成分和经济性状等指标探究腐植酸对烤烟品种云烟87产量和质量的影响。T2和T3处理的各方面皆优于T1处理和对照,在农艺性状及田间生长势方面T2与T3处理基本相同,T3处理株高及叶面积稍高于T2处理;各部位烟叶干鲜比T2处理较好;烤后烟叶的化学成分中,C3F等级烟叶T2处理最佳,B2F等级烟叶T3处理烟碱及氮含量稍高于T2处理;T2与T3处理烟叶评吸质量相差不大,T2处理香气质及香气量稍多;经济价值方面,T2处理产量、产值均为最佳。经对比分析得出,T2处理为最佳浓度处理。
Qianjiang tobacco area is a high-altitude rainy tobacco area with low temperature before and after transplanting,which is not conducive to the growth and development of tobacco seedlings.To improve this situation,a rooting agent containing humic acid water-soluble fertilizer was applied in a concentration gradient in 2022.After transplanting the tobacco seedlings,it was divided into four concentration treatments,namely:CK(0 mg/L),T1(60 mg/L),T2(90 mg/L),T3(120 mg/L).Each plot was irrigated and sprayed with 50 L solution according to the concentration of T1,T2 and T3 treatments.The effects of humic acid on the yield and quality of flue-cured tobacco variety of Yunyan 87 were investigated from agronomic traits,appearance quality,chemical composition and economic traits of flue-cured tobacco leaves.T2 and T3 treatments were better than T1 treatment and CK in all aspects,while the agronomic traits and field growth potential of T2 and T3 treatments were basically the same,the plant height and leaf area of T3 treatment was slightly higher than those of T2 treatment;the dry fresh ratio of all parts of the tobacco of T2 treatment was better.In the chemical composition of flue-cured tobacco leaves,the C3F grade of tobacco leaves of T2 treatment was the best,and the nicotine and nitrogen contents of T3 treatment in B2F grade tobacco leaves were slightly higher than those of T2 treatment.The tobacco evaluation of smoking quality of T2 and T3 treatments was not much different,the aroma and aroma amount of T2 treatment were slightly more;In terms of economic value,the yield and output value of T2 treatment were the best.After comparative analysis,it was concluded that T2 treatment was the best concentration treatment.
