为了探讨玉米不同株行距配置、玉米宽行双株种植方式对玉米产量和农艺性状的影响,于2015年开展了本试验。结果结果表明:同一个品种在同一试验点,等行单株种植、等行双株种植和不同种植量条件下,其各个生育时期和生育期的天数没有变化;不同种植量的株高、穗位、空秆率略有变化;随着种植密度的增加,有穗长变短、穗粗变细和秃尖增加的趋势;其穗行数、行粒数、穗粒数、千粒质量、出籽率和单穗粒质量均有减少趋势。宽行双株种植比当地大田常规种植方法667 m~2产量增长25%左右。
In order to investigate the effects of different row spacing of maize lines and the effect of planting double rows of maize wide lines on the yield and agronomic characters of maize, this experiment was carried out in 2015. The results showed that: the same species in the same test point, the same line of single plant planting, double line planted under different planting conditions and the number of days of each growth period and growth period did not change; different planting plant height, spike There was a slight change in the percentage of stalks and empty stalks. With the increase of planting densities, there was a tendency of shorter spike, thinner and thinner spikes, and more bald tip. The number of rows per plant, the number of rows and rows, the number of grains per spike, Seed yield and grain weight per panicle decreased. Wide double row plant than the local field conventional planting methods 667 m ~ 2 output increased by about 25%.
