摘　　要：探究聚谷氨酸施用对烤烟品种红花大金元(以下简称“红大”)烟叶品质的影响,以期为提高特色品种红花大金元烟叶产量和品质提供参考依据。采用大田试验,以烤烟品种红花大金元为供试材料,试验设置5个施肥梯度,即喷施清水(CK),喷施聚谷氨酸0.05 g·L^(-1)(T1)、0.1 g·L^(-1)(T2)、0.2 g·L^(-1)(T3)、0.4 g·L^(-1)(T4)以研究叶面喷施不同浓度的聚谷氨酸对烟叶外观及内在品质的影响。结果表明:与对照(CK)相比,施用聚谷氨酸提高烟叶单叶质量、叶面密度、拉力、平衡含水率,降低含梗率,且随聚谷氨酸施用浓度的增加呈降低趋势;聚谷氨酸对烟叶外观质量的影响与施用浓度有关,但规律不明显;低浓度和高浓度条件下聚谷氨酸施用烟叶化学成分协调性总体状况优于CK;随着聚谷氨酸喷施浓度的增加,感官质量综合指数值呈先升后降趋势,但均优于CK。总体来看,喷施聚谷氨酸改善烟叶外在质量和内在品质效应受施用浓度的影响,整体以叶面配施0.2 g·L^(-1)聚谷氨酸(T3)处理烟叶的整体品质较佳。The effects of polyglutamic acid application on tobacco leaf quality of flue-cured tobacco variety Honghua Dajinyuan(hereinafter referred to as“Hongda”)was studied in order to provide reference for improving the yield and quality of flue-cured tobacco.Using field tests,the flue-cured tobacco variety Hongda was used as the test material,and five fertilization gradients were set up in the experiment,that is,spraying water(CK),spraying polyglutamic acid 0.05 g·L^(-1)(T1),0.1 g·L^(-1)(T2),0.2 g·L^(-1)(T3),0.4 g·L^(-1)(T4)to study the effects of spraying different concentrations of polyglutamic acid on the appearance and internal quality of tobacco leaves.The results showed that compared with the control(CK),application of polyglutamic acid increased leaf weight,leaf surface density,tension and equilibrium water content,and decreased stem content,and showed a decreasing trend with the increase of application concentration of polyglutamic acid;The effect of polyglutamic acid on the appearance quality of tobacco leaf was related to the application concentration,but the rule was not obvious;The chemical composition coordination of tobacco leaves applied with polyglutamic acid was better than CK under low concentration and high concentration conditions;With the increase of polyglutamic acid concentration,the comprehensive index value of sensory quality increased first and then decreased,but it was better than CK treatment.In general,the effect of spraying polyglutamic acid on the external quality and internal quality of tobacco leaves is affected by the application concentration,and the overall quality of tobacco leaves treated with 0.2 g·L^(-1) polyglutamic acid(T3)is better.
