为探明生物活性肥对烤烟生长发育和烟叶品质的影响效果 ,于 2 0 0 0年 (大田试验 )和 2 0 0 1年 (盆栽试验 ) ,对 AA,BA两种不同生物活性肥的施用效果进行了研究 .盆栽试验的结果表明 :对照 (不施活性肥 )处理旺长前期促进烤烟地上部分生长发育的作用优于 BA和 AA处理 ;AA处理则在中、后期对增大烤烟最大叶叶面积的作用最明显 ;AA处理叶绿素含量、根系活力分别较对照提高 14.1%～ 2 3 .8% ,8.1%～ 2 8.4% ;成熟后期烟株地上部分干物质量、烟叶含钾量分别提高 8.3 % ,17.0 % ,而含氮量降低 5 .3 % ;烟叶腹面腺毛数 AA处理比 CK提高 3 1.5 % .大田试验的结果表明 :施用生物活性肥能提高烟叶产量和品质
In order to find out the effect of bioactive fertilizer on the growth and development of flue-cured tobacco and the quality of tobacco leaves, the application of two different biologically active fertilizers, AA and BA, in 2000 (field trial) and 2001 (pot experiment) The results of pot experiment showed that: the control (non-applied fertilizer) to deal with Mongolian and long before the promotion of aerial parts of flue-cured tobacco growth and development better than the BA and AA treatment; AA treatment in the mid and late to increase the largest leaf of tobacco Leaf area had the most obvious effect. The chlorophyll content and root vigor of AA treatment increased by 14.1% ~ 23.8% and 8.1% ~2 8.4%, respectively. The dry matter content of tobacco shoots and the content of potassium in tobacco leaves increased by 8.3% % And 17.0%, respectively, while the nitrogen content decreased by 5.3% .The number of glandular trichomes in the ventral surface of the tobacco increased by 31.5% compared with CK.The results of the field trial showed that the application of bioactive fertilizer could improve the yield and quality of tobacco
