摘要
为研究硒对花生不同品种在不同地区的光合特性、经济性状、籽仁硒含量及产量的影响,以郑农花25 号、郑农花28 号、郑农花29 号、郑农花33 号为材料,分别在郑州、焦作、南阳三地区在花生盛花期后进行叶面喷施硒肥.结果表明:叶面喷施硒肥可以提高花生叶片的叶绿素含量、光合速率、蒸腾速率,可以提高花生主茎高、侧枝长、单株饱果数、百果重、百仁重、出米率,也可以提高花生籽仁中硒含量,提高花生荚果及籽仁的产量.
Abstract
In order to investigate the effects of selenium on the photosynthetic characteristics,economic traits,selenium content in seed kernels,and yield of different peanut varieties in different regions,the varieties'Zhenonghua 25','Zhenonghua 28','Zhenonghua 29',and'Zhenonghua 33'were used as materials.Se-lenium fertilizer was foliar-applied after the peak flowering stage in Zhengzhou,Jiaozuo and Nanyang.The re-sults showed that foliar application of selenium fertilizer increased the chlorophyll content,photosynthetic rate,and transpiration rate of peanut leaves.It enhanced the main stem height,lateral branch length,number of full pods per plant,weight of 100 pods,weight of 100 kernels,kernel yield percentage,selenium content in the ker-nels,and the yield of both pods and kernels.
