摘要 为了探究割苗在河南省夏玉米生产上的适用性,以登海605、豫单9932、金秋119为材料,在苗期5~6片可见叶时进行割苗处理,研究割苗对夏玉米生长及产量的影响。结果表明,割苗使3个玉米品种的生育时期均延迟,株高和穗位高降低,茎秆变细,叶面积指数、干物质积累量、根冠比等均显著降低;割苗使登海605和豫单9932虫害均加重;割苗使登海605和金秋119收获指数分别增加4.55%和4.46%,豫单9932收获指数降低2.25%;割苗使登海605和豫单9932百粒质量均显著增加,而穗粒数显著减少,金秋119百粒质量显著减少,而穗粒数显著增加;割苗使登海605增产3.52%,豫单9932和金秋119分别减产3.46%和2.18%;割苗对籽粒粗淀粉含量影响显著,但品种间存在差异。综上说明,割苗技术在河南省夏玉米区不具推广价值。 In order to explore the applicability of cutting seedlings in the production of summer maize in Henan province,the influence of cutting seedlings on the growth and yield of summer maize was studied with Denghai 605,Yudan 9932 and Jinqiu 119 as materials.Cutting seedlings was done when the number of visible leaves was 5-6 at the seedling stage.The results showed that cutting seedling delayed the growth period of the three maize varieties,reduced plant height and ear height,significantly decreased stem diameter,leaf area index,dry matter accumulation and root to shoot ratio.For cutting seedling treatment,the insect pest of Denghai 605 and Yudan 9932 aggravated;harvest indexes of Denghai 605 and Jinqiu 119 increased by 4.55% and 4.46% respectively,while harvest index of Yudan 9932 decreased by 2.25%;100-grain weight of Denghai 605 and Yudan 9932 significantly increased,but grains number per ear significantly decreased,while 100-grain weight of Jinqiu 119 significantly decreased,but grains number per ear increased significantly;the yield of Denghai 605 increased by 3.52%,the yields of Yudan 9932 and Jinqiu 119 decreased by 3.46% and 2.18% respectively.The effect of cutting seedlings on the content of coarse starch was significant,but there was difference among different varieties.To sum up,cutting seedlings did not have the promotion value in summer corn region of Henan province.
