不同栽培措施对山东烟区KRK26生长发育及烟叶品质的影响OA
Effects of Various Cultivation Measures on Growth and Development of KRK26 and Tobacco Leaf Quality in the Shandong Tobacco Region
为系统探究施氮量、种植密度和留叶数对山东烟区烤烟生长发育及烟叶品质的影响,以烟草品种KRK26为试验材料,分别设置45(CK)、60(T1)、75 kg/hm²(T2)3个施氮水平;行距120 cm×株距60 cm(CK)、行距120 cm×株距50 cm(M1)、行距120 cm×株距40 cm(M2)3个种植密度;20(CK)、22(Y1)、24片/株(Y2)3种留叶数,对不同栽培措施下的烟株生长、产量、产值、外观质量、烤后烟叶化学及感官品质进行测定与分析.结果显示,不同施氮量下,与CK相比,T2处理烟株上部叶和中部叶的烟碱、总氮含量分别增加了 8%、7%和29%、5%,总糖、还原糖含量分别下降了14%、8%和10%、5%;T1处理烟株上部叶和中部叶的绿原酸和芸香苷含量最高,且其感官质量综合得分、产量及产值均最高.不同种植密度下,与CK相比,M2处理烟株上部叶和中部叶的总糖和还原糖含量分别增加了35%、5%和41%、12%,而烟碱和总氮含量分别下降22.7%、22.5%和17.0%、9.0%;M1处理烟株上部叶和中部叶的感官质量综合得分最高,分别为67.35、70.30,且产量和产值均最高.不同留叶数下,随着留叶数的增加,烟碱和总氮含量呈先降后升的趋势,而总糖、还原糖、绿原酸和芸香苷的含量呈先升高后降低的趋势,其中,Y1处理烟株上部叶和中部叶的感官质量综合得分最高.综上,施氮量60 kg/hm2、种植密度行距120 cm×株距50 cm、留叶数22片叶时,可促进KRK26烟草的生长,提高烟叶的产量和品质.
To systematically investigate the effects of nitrogen application rate,planting density,and leaf retention number on the growth and development of flue-cured tobacco and the quality of tobacco leaves in Shandong tobacco regions,in this study,tobacco variety KRK26 was used as the experimental material.Three nitrogen application rates were set:45(CK),60(T1),and 75 kg/hm²(T2),three planting densities were set:row spacing 120 cm,plant spacing 60(CK),50(M1),and 40 cm(M2),three leaf retention numbers were set:20(CK),22(Y1),and 24 leaves per plant(Y2).The growth,yield,output value,appearance quality,chemical and sensory quality of tobacco leaves after curing of tobacco plants under different cultivation measures were measured and analyzed.The results showed that under the different nitrogen application rates,compared with CK,the nicotine and total nitrogen contents of the upper and middle leaves of T2 treatment plants increased by 8%and 7%,29%and 5%,respectively,while the total sugar and reducing sugar contents decreased by 14%and 8%,10%and 5%,respectively.The chlorogenic acid and rutin contents of the upper and middle leaves of T1 treatment plants were the highest,and its comprehensive sensory quality score,yield,and output value were also the highest.Under the different planting densities,compared with CK,the total sugar and reducing sugar contents of the upper and middle leaves of M2 treatment plants increased by 35%and 5%,41%and 12%,respectively,while the nicotine and total nitrogen contents decreased by 22.7%and 22.5%,17%and 9%,respectively.The comprehensive sensory quality score of the upper and middle leaves of M1 treatment plants was the highest,being 67.35 and 70.3 points,respectively,and the yield and output value were also the highest.Under the different leaf retention numbers,with the increase of leaf retention number,the contents of nicotine and total nitrogen showed a trend of first decreasing and then increasing,while the contents of total sugar,reducing sugar,chlorogenic acid,and rutin showed a trend of first increasing and then decreasing.Among them,the comprehensive sensory quality score of the upper and middle leaves of Y1 treatment plants was the highest.In conclusion,when the nitrogen application rate was 60 kg/ha,the planting density was 120 cm×50 cm,and the leaf retention number was 22,the growth of KRK26 tobacco was promoted,the yield and quality of tobacco leaves were increased.
