摘要
采用田间试验方法,以微生物菌剂为研究对象,设置4个处理:对照(T_1,CK)、蘸根处理(T_2)、蘸根处理+团棵期喷施(T_3)、蘸根处理+团课期喷施+旺长期喷施(T_4),研究了微生物菌剂对烤烟生长发育、光合特性及产质量的影响,结果表明:与T_1相比,T_3、T_4处理显著提高了烟株株高、茎围、叶片数和最大叶片值;增加了叶片光合色素的含量,改善了叶片光合性能;降低了烤后烟叶中烟碱和氯离子含量,提高了钾离子含量;提高了烟叶的产量、产值和中上等烟比例,显著增加了烟农的经济效益。
The effects of microbial agent on the growth,development,photosynthetic characteristics,yield and quality of flue-cured tobacco were studied through field experiments by setting up the following 4 treatments： the control（ T1,CK）,dipping roots（ T2）,dipping roots＋ spraying at resettling stage（ T3）,dipping roots＋ spraying at resettling stage＋ spraying at vigorous growth stage（ T4）. The results showed that： as compared with the control T1,the treatments T3 and T4 could significantly improve the plant height,stem circumference,leaf number and maximum blade value of tobacco plants; could increase the content of photosynthetic pigments in leaves,and improve their photosynthetic performance; could reduce the contents of nicotine and chloride ion in the cured tobacco leaves,and increase their potassium ion content; could enhance the yield and output value of tobacco leaves,as well as the proportion of medium and first-class tobacco leaves,and significantly increase the economic benefits of tobacco-planting farmers.
