| 摘 要： | 为探索氮肥施用量对辣椒农艺性状及产量的影响,设计6个氮肥施用处理,采用随机区组设计,测定农艺性状、果实性状和小区产量。结果表明,不同氮肥处理对辣椒株高、株幅、茎粗、果长、果肩宽、单果鲜重、单株果实鲜重、单株结果数、小区产量鲜重有显著影响,呈先增长后降低的趋势。在施氮量14.99kg/667m^2时,小区鲜椒产量达到最大值,为6913.80g,折合产量为1281.83kg/667m^2。

| Abstract: | In order to explore the effects of nitrogen fertilizer application on agronomic traits and yield of pepper,six nitrogen fertilizer application treatments were designed and random block designs were used to determine agronomic traits,fruit traits,and plot yield.The results showed that different nitrogen fertilizer treatments had significant effects on pepper plant height,plant width,stem thickness,fruit length,fruit shoulder width,fresh weight per fruit,fresh fruit weight per plant,fruit number per plant,and fresh weight of plot.By fitting the curve,taking the fresh weight of the plot as the target,the maximum value was 6913.80 g at the nitrogen application rate of 14.99 kg/667 m^2,which was converted to 1281.83 kg/667 m^2 fresh pepper. |
