摘要
2007～2008年在湖北省房县、恩施市和利川市3个试验点进行了烤烟沼液适宜施用量研究,结果表明,施用沼液对烟株生长发育有一定的促进作用,可以增加团棵期的叶长、叶宽、株高,提高生物量,促进烟株对氮、磷、钾养分的吸收与积累,并且对烟株的生育期没有明显的影响;烟叶经济性状差异显著性分析表明,产量、产值方面在不同处理间的差异达到了5%显著水平或1%极显著水平,以施用7 500 kg/hm2沼液处理的烤烟产量、产值最好,相比对照而言,增产幅度为3.8%～17.0%,增值幅度为1.4%～17.5%;并且7 500 kg/hm2沼液处理可提高烟叶内在化学成分的协调性,改善烟叶的评吸品质。
The suitable content of biogas slurry for flue-cured tobacco in Fang county,Enshi city and Lichuan city of Hubei province were studied from 2007 to 2008.The results indicated that,application of biogas slurry accelerated the growth and development of the flue-cured tobacco,and added leaf length,width,height in resettling stage,and also increased the biomass and the content of N,P,and K nutrient in flue-cured tobacco leaf,but had no obvious effect on the growth of flue-cured tobacco.The results of Fang county,Enshi city and Lichuan city showed that： significant differences at the 0.05 level or highly significant differences at the 0.01 level were found among treatments with different content of biogas slurry,the treatment of the highest output and value was adding 7 500 kg/hm2 biogas slurry.The output was increased from 3.8% to 17.0% compared with the control,and the value from 1.4% to 17.5%.Adding 7 500 kg/hm2 of biogas slurry increased the coordination of inherent chemical composition,and improved the sensory quality of flue-cured tobacco.
