根据江苏沿海地区土壤特点和肥力状况 ,初步研究了氮、磷配施对皖油 14油菜产量构成的影响。结果表明 ,在密度一定的情况下 ,氮、磷的不同用量和配比与皖油 14的单株角果数、每角粒数、千粒重等因素有一定的相关性。边际分析结果显示 ,在江苏沿海地区皖油 14最佳施肥量为N 13.90kg/6 6 7m2 、P2 O56 .37kg/6 6 7m2 。
According to soil characteristics and fertility status in coastal areas of Jiangsu Province, the effects of nitrogen and phosphorus fertilizers on the yield components of Wanyou 14 were preliminary studied. The results showed that under certain density, the different amount and proportion of N and P were related to the number of pods, grains per horn, 1000-grain weight and other factors. The results of marginal analysis showed that the best fertilization rate of Wanyou14 was N 13.90kg / 667m2 and P2 O56.37kg / 667m2 in coastal area of Jiangsu Province.
