| 摘 要： | 以北京红红干椒为试材,研究了不同施氮量对轮作、连作红干椒生理特性及产量的影响。结果表明:施氮能明显提高红干椒的光合速率、蒸腾速率、气孔导度,提高幅度以高氮处理最大,同一施氮量下,以上3个指标均表现为轮作高于连作,但轮作与连作之间的差异不大。有效产量也随施氮量的增加而增大,中氮和低氮处理轮作和连作的差异分别达到极显著水平和显著水平,而高氮处理轮作和连作之间差异不显著。因此,加大施氮量是提高红干椒连作能力的有效途径。

| Abstract: | Effects of different nitrogen amount on physiological characteristics and yields of rotation and continuous cropping were studied using red chilliBei Jing Hongas experimental materials.The results showed that applying nitrogen could significantly increase photosynthetic rate,transpiration rate and stomatal conductance.The increasing range of high nitrogen treatment was the biggest.The three indexes of rotation were all higher than those of continuous cropping under the same nitrogen applying amount,however,... |
