摘要
通过田间小区试验,研究了烤烟与甘薯套种对烟叶质量和经济效益的影响。结果表明,烤烟套种甘薯与烤烟单作相比较,原烟产量增加117.99 kg/hm^2,增幅为4.26%;上等烟、中等烟分别提高0.9～1.84个百分点和1.49～6.51个百分点,其增幅分别为3.24%～14.53%和4.54%～12.44%;下等烟降低2.39～8.85个百分点,减幅为10.08%～25.28%。原烟均价增加0.50～0.53元/kg,增加幅度为4.38%～4.56%。收薯块为3226～7856 kg/hm2,薯藤19351～36 520 kg/hm2,分别增收3871～9427元/hm2和5805～10 956元/hm2;综合增加经济收入16 368～18 133元/hm^2,增收幅度达48.82%～56.40%,差异达到显著水平。
Field experiment were conducted to investigate the effects of flue-cured tobacco and sweet potato intercropping on quality and economic benefits of flue-cured tobacco leaves.The results were as follow： compared with monocropping,flue-cured tobacco intercropping with sweet potato the yield of flue-cured tobacco leaves were increased 117.99 kg per hectare and increased by 4.26%,the proportion of superior and middle tobacco leaves were increased by 3.24 %-14.53 % and 4.54 %-12.44 %,respectively,meanwhile the proportion of low-grade leaves was decreased by 10.08% and 25.28%.The average price of flue-cured tobacco leaves were increased by 0.50-0.53 yuan per kilogram and the rise range was between 4.38 %-4.56 %.In addition,the sweet potato tube and bushrope yield were increased by 3226-7856 and 19 351-36 520 kilogram per hectare,respectively,income respectively increased by 3871-9427 and 5805-10956 yuan per hectare,the total economic income were increased 16 368-18 133 yuan per hectare and increased by 48.82 %-56.40 %,the different of producing value is significant at 5 % level.
