烤烟高效栽培及套种免耕玉米关键技术初探

A primary discussion on key technologies of fluecured tobacco high-effect cultivation and interplanting in no-tillage maize field

夏烟、夏玉米同处于一个生长季节,烟粮争地矛盾突出。为解决烟粮争地的矛盾,探索出烟套玉米技术模式:烤烟套种玉米即当烤烟采收至中上部叶片时(时间规定在6月底至7月20日),在其行间或株间种植玉米,让烤烟与玉米共生一段时间,烤烟采收完后及时管护玉米。试验表明,该模式提高了复种指数,烤烟收入2000元以上,免耕玉米收入450㎏以上,达到钱粮双收的目的。

Summer tobacco and summer maize are growing at same season, which results in the farmland occupying conflict. In order to solve this problem, a tobacco interplanting with maize mode has been experimented. The interplanting period is from the end of June to 20th of July, which allow the maize co-growing with tobacco for a stage, and the maize will be managed timely after harvesting the tobacco leaves. The experiment results show that this mode can increase multiple cropping index, tobacco income by over 2000 Yuan and maize yield by over 450 kg so as to reach the objective of in- creasing income and grain yield.
