摘　　要：为探索叶面喷施微生物肥"吉纳泰"对烤烟产质量的影响,2018年以喷施清水为对照,并设置原液及原液用清水稀释15,30,60倍等4个处理,开展小区比较试验.结果表明:1)"吉纳泰"以各种稀释倍数叶面喷施对改善烤烟农艺性状、生长势、抗病性及增加烟叶两糖比等均有一定的正向作用,其中以稀释30倍或60倍的叶面喷施对烟叶外观质量和经济性状的改善作用明显,特别是稀释60倍处理的烟叶产值、产指两项指标与其他处理差异有统计学意义.2)"吉纳泰"各种稀释倍数对提高上部烟叶钾质量分数具有一定的正向作用,但对改善烟叶氮碱比的效应则不同,其中以稀释30倍或60倍的叶面喷施对改善上部叶氮碱比有利,喷施原液或15倍稀释液对改善上部叶氮碱比不利.因此,在2016-2017年试验的基础上进一步探索了"吉纳泰"在烟草上的应用效果,并明确该肥料叶面喷施的最佳稀释倍数.In order to explore the effect of microbial fertilizer“Ji Natai”with foliage spraying on yield and quality of flue-cured tobacco,in 2018,spraying pure water as treatment CK,4 different concentration treatment was set,including the stock solution,15 times dilution,30 times dilution and 60 times dilution,a plot experiment was conducted.The results showed that:1)Various spraying concentration of this fertilizer has a certain positive effect on agronomic traits,growth potential,disease resistance and increase of ratio of reducing sugar to total sugar in tobacco leaf,and there exists obvious improvement on appearance quality and economic indicators of tobacco leaf with foliage spraying after 30 times or 60 times dilution,especially the differences of the value and price index of the spraying treatment after 60 times dilution show the statistic significance.2)Various spraying concentration of this fertilizer has a certain positive effect on the increase the quality of potassium content in upper leaf,however,it has different effect on improvement of ratio of total nitrogen to nicotine in tobacco leaf,and spraying after 30 times or 60 times dilution is beneficial to improve the ratio of total nitrogen to nicotine in upper leaf,but spraying stock solution or 15 times dilution is harmful to improve the ratio of total nitrogen to nicotine in upper leaf.Therefore,based on the experiment in 2016 and 2017,this research further explored the application effect of this fertilizer on tobacco,indicating the best concentration of this fertilizer for foliage spraying.
