对辽西地区玉米高产品种和技术模式进行筛选研究,提高辽西地区玉米综合生产能力。研究结果表明:不同品种的株高间达到了极显著差异,不同品种之间的产量性状各异,产量以辽单565最高,为11980.50kg/hm2;中农4号最小,为5 692.50 kg/hm2。不同技术模式对辽单565株高和产量性状影响各异,以双层施肥处理最大,为11005.50kg/hm2;双珠定向处理最小,为7480.00kg/hm2。
The high-yielding varieties and technical patterns of corn in western Liaoning were screened to improve the comprehensive corn production capacity in western Liaoning. The results showed that there were extremely significant differences among the plant height of different cultivars, and the yield traits varied among different cultivars. The yield of Liaodong 565 was the highest, which was 11980.50kg / hm2 and that of Zhongnong 4 was 5 692.50 kg / hm2 . Different technical models had different effects on the plant height and yield traits of Liaodong 565, with the largest double-layer fertilization treatment being 11005.50 kg / hm2; the smallest double-bead directional treatment was 7480.00 kg / hm2.
