摘要 运用均匀设计,以杂交水稻谷优明占为材料,分析不同秧龄、密度和纯N量对产量的影响,建立产量与3项栽培措施的回归模型。结果表明,3项措施均对谷优明占的产量有影响。经微机模拟筛选,秧龄25.4~29.7 d、插植密度30.1万~33.2万丛· hm -2、施纯 N量183.8~210.0 kg · hm -2是谷优明占产量达到8250 kg · hm -2以上的高产栽培技术措施。 Uniform design was used to analyze the cultivation of the high yield ,hybrid rice ,Guyoumingzhan ,based on three factors :seedling age (X1 ) ,planting density (X2 ) and quantity of nitrogen (X3 ) . The regression models for the three factors affecting the rice yield were established . The experimental results revealed that the three factors exerted significant influences on the yield , After a simulated screening and optimization by computer , seedling age in the range of 25.4-29.7 d for transplanting at the density of 301 000-332 000 hills · hm-2 with a nitrogen application of 183.8-210.0 kg · hm -2 was recommended for the cultivation on yield ≥ 8 250 kg · hm-2 .
