中文摘要: |
为寻求最佳种植模式,实现春玉米高产稳产,以桂单162 为试材,4 种行距配置方式为主处理,4
种种植密度为副处理,裂区设计,研究不同行距与密度配置方式下的玉米产量变化规律。结果表明:密度、行
距× 密度互作的玉米产量差异达到极显著水平,在等行距60 cm、等行距75 cm、宽窄行80 cm×40 cm 配置
3 000 株/667m2 密度栽培时玉米穗粒数及产量表现较好,在宽窄行90 cm×40 cm 栽培时配置3 500 株/667m2
密度穗粒数及产量表现较好,获得最高产量的玉米种植模式为宽窄行80 cm×40 cm + 3 000 株/667m2。在实际
的生产中,应结合品种自身特性合理选择种植模式实现增产目标。 |
英文摘要: |
To obtain the best cultivation method of maize,and achieve high and stable yield of spring maize,
Split Plot Design with main treatments of 4 different row spacing and vice treatments of 4 different density was
used,taking Guidan 162 as materials,to study the yield of corn under different densities and row spacing. The
results showed that,density and the interaction of density and row spacing had very significant effects on corn
yield. The grains per ear and yield of maize showed well in the density of 3 000 plants/667m2 under the row spacing
of 60 cm,70 cm and 80 cm×40 cm,showed well in the density of 3 500 plants/667m2 under the row spacing of
90 cm×40 cm. The cultivation model of high yield was the row spacing of 80 cm×40 cm with the density of 3 000
plants/667m2. In the actual production,proper cultivation method in accordance with varietal characteristics may
improve the maize yield. |
