玉米“四密21”高产栽培配套技术研究

Study about the Form a Complete Set Skill of the High Yield Culture on the Maize Simi 21

报告了在黑土平岗地上，３１米薯间作不计马铃薯产量的情况下，对玉米“四密２１”品种实现产量１３９７７．３０ｋｇ／ｈｍ２的生育期、生物学特性及产量构成等客观因素进行了分析，得出了玉米“四密２１”品种高产的原因在于群体优势强、单株生产力高，并提出了提高其单产的综合配套技术措施。

Through interplanting maize hybrid Simi 21 and potato with 31 in fertile plain This article analyzed aseries of objective factors including growing-period and biological character and yield, under the condition of 13977.30kg/hm2 maize was obtained excluding the potato yield.The reason of highyield was induced to powerful predominance of population and highyield of single plant, while the comprehensive cooperated technology for raising yield on maize hybrid Simi 21 was proposed.
