| 摘 要： | 通过对玉米(Zea mays L.)郑单958进行4种密度和3种留苗方式的组合试验,探讨其最佳种植密度及留苗方式.结果表明,不同密度及不同留苗方式间产量均存在显著差异,郑单958的适宜种植密度为7.5万～9.0万株/hm2;每穴单株三角留苗方式产量最高.郑单958在豫北地区的适宜种植密度和留苗方式组合是:密度9.0万株/hm2和每穴单株三角留苗,单产为9 750.49 kg/hm2.

| Abstract: | The combination tests of 4 levels of plant density and 3 kinds of seedling leaving mode were conducted to optimize the two cultivation conditions of Zhengdan 958.The results showed that the yield of Zhengdan 958 differed significantly according to different plant density and seedling leaving mode.The appropriate plant density for Zhengdan 958 was 75 000～90 000 ind./plant;while the highest yield could be obtained when single-strain per hole with triangular seedling leaving mode was applied.The optimum combination of cultivation conditions for Zhengdan 958 in north Henan was density at 90 000 ind./plant and single-strain per hole with triangular seedling leaving mode. |
