摘要
为增加武陵山区烟农收入,探讨以烟为主,适宜武陵山区旱地烟区的套作方式,通过田间小区试验,总结出一套烟草与半夏套种栽培技术模式,并调查半夏与烟草的套作模式对经济效益和烟草生长的影响。结果表明,烟草与半夏套种,平均纯收入为116900元/hm2,与2种单独常规种植方法相比,分别提高了323%和24%。套种模式与烟草单独连续种植相比,烟草青枯病发病率平均降低72.38%,烟草黑胫病发病率平均降低87.01%,烟草立枯病发病率平均降低73.96%。该模式的推广和应用,可提高土地复种指数、降低烟草病害、减轻烟草连作障碍、促进烟农增收增效。
In order to increase the income of tobacco farmers in Wuling Mountain area,the interplanting pattern of tobacco and Pinellia ternata(Thunb.)Breit.was studied in tobacco area of Wuling Mountain area by plot test.The intercropping cultivation techniques of tobacco and Pinellia ternata were summarized,and its economic benefits were analyzed.The results showed that the average net income of tobacco interplanted with Pinellia ternate was 116900 yuan/hm2,which was 323%and 24%higher than that of the conventional planting methods alone.The incidence of tobacco bacterial wilt,tobacco black shank and tobacco damping-off decreased by 72.38%,87.01%and 73.96%,respectively.The extension and application of this model could improve the index of multiple cropping,reduce tobacco diseases,reduce tobacco continuous cropping obstacles,and promote the increase of farmers′income and efficiency.
