| 摘 要： | 以郑单958为试验材料，设置两个种植密度(82500、97500株/hm2)、5个行距配置(60+60、70+50、80+40、90+30、100+20 cm)和4种不同留苗的株距配置(单株、单双、双株、三株)方式，研究高密度条件下株行距配置对玉米产量及灌浆特性的影响。结果表明，两个密度条件下均以80+40行距、双株留苗处理产量最高，密度增加，增产效果更好。宽窄行配置增加了穗行数和穗粗，减小秃尖长，双株留苗增加玉米穗粒数和千粒重；80+40行距配置、双株留苗处理改变了玉米后期的灌浆特性，增加渐增期持续时间和累积子粒量，增大了平均灌浆速率。因此，在豫西地区高密度种植条件下，采用80+40的种植行距，通过双株留苗扩大株距，有利于玉米高密度群体植株的生长和最终产量的提高。

| Abstract: | With Zhengdan958 as the experimental material, set two densities(82 500 plants/ha and 97 500 plants/ha), five row spacing(60+60, 70+50, 80+40, 90+30, 100+20 cm), and four kinds of different seedling plant spacing configurations(single, single & double, double plants, three plants), to study the effect of maize yield and grain filling characteristics of row & spacing under high density plant. The results showed that, two densities conditions with the highest yield were 80+40 processing rows spacing, double plant seedling. The breeding with the conditions could increase the number of rows per ear, increase ear diameter, reduce bald tip, and increase grain number per ear and weight. 80+40 rows spacing and 2 plants seedling will improve the plant space, change maize later grain filling characteristics, increase the cumulative duration and cumulative grain weight, increase the average filling rate. Therefore, high density planting condition, recommended using 80+40 plant densities and double plants in the western region of Henan province. |
