摘要
为摸索玉米不同密度、品种及其不同组合对生产的影响,利用条区试验设计,研究品种和种植密度对玉米产量的影响。结果表明:不仅品种和密度是影响产量的重要因素,而且品种不同适宜密度也不同。密度以3 335株/667 m2产量最高;品种以新中玉801产量最高;新中玉801、帮豪108和Q玉7号三个品种的最适宜密度分别是3 668株/667 m2、3 335株/667 m2和3 001株/667 m2。
The effects of plantation densities and cultivars on yield of maize were investigated by strip - plot design. The results showed that optimal plantation density was 3 335 plants per 667 ㎡, and its best cultivar was Xinzhongyu 801, The suitable plantation densities of Xinzhongyu 801, Qyu 7 and Banghao 108 were 3 001, 3 335 and 3 668 plants per 667㎡, respectively.
