摘要
2008年4～9月在地处西辽河平原的内蒙古民族大学实验农场进行了不同施N水平对红干椒光合特性及产量影响的研究。结果表明：高氮水平下红干椒保持较高的光合速率,而蒸腾速率在14：00之前较高,之后各处理间差别不大。施氮对株高的影响不大,株展随施氮量的增加而增大,受有效椒率的影响,有效产量以N5最高,兼顾高产高效,红干椒高产栽培施氮量以187.5 kg/hm2最佳。
Effects of different nitrogen levels on yeild of red dry peper and physiological characters were studied on experimental farm of the Inner Mongolia University for Nationalities in Xiliaohe Plain from April to September in 2007.The results showed that： red dry peper had high photosynthetic rate under the high nitrogen level,however,transpiration rates were higher before 14：00 and then each treatment had no obvious differences.Nitrogen fertilizer had little influence on plant height. With the increasing of nitrogen fertilizer, plant exhibition increased and related with rates of effective peper. The effective yeild was highest under the N5 and the optium nitrogen fertilizer amount for red dry peper high yeild cultivation was 187.5 kg/hm^2.
