摘要
采用三因素四水平的正交试验设计,研究了纯N、P_(2)O_(5)和密度对高产高抗高油适宜机械化的甘蓝型半冬性细胞质不育三系杂交种汉油1428的经济性状和产量的影响。结果表明:N肥和密度对该品种的农艺性状和产量影响显著,汉油1428以纯N 14 kg/667m^(2)、P_(2)O_(5)4.83 kg/667 m^(2)、密度2.8万株/667 m^(2),可以获得较高的产量,可为油菜品种的推广提供参考。
A three-factor,four-level orthogonal experimental design was adopted to investigate the effects of pure nitrogen(N),phosphorus pentoxide(P_(2)O_(5)),and plant density on the agronomic traits and yield of Hanyou 1428,a semi-winter cytoplasmic male sterile three-line hybrid of Brassica napus characterized by high yield,strong resistance,high oil content,and suitability for mechanized production.The results showed that nitrogen fertilizer and plant density had significant effects on the agronomic traits and yield of this variety.Under the conditions of 14 kg/667 m^(2)of pure nitrogen,4.83 kg/667 m^(2)of P_(2)O_(5),and a density of 28,000 plants/667 m^(2),Hanyou 1428 achieved a relatively high yield,providing data support for its extension.
