摘　　要：以仁用杏为研究对象进行田间小区试验,设置仁用杏间作大豆、仁用杏间作花生、仁用杏间作谷子、仁用杏单作4个处理,考察不同间作模式对仁用杏新梢生长节律、叶片光合色素及叶绿素荧光参数的影响。结果表明:间作大豆、间作花生和间作谷子模式的仁用杏叶片叶绿素a、叶绿素b及叶绿素总量的年变化均呈上升—下降趋势,叶绿素a/b值年变化呈上升—下降—上升趋势;3种间作模式均提高了叶绿素a、叶绿素b及叶绿素总量,同时仁用杏间作花生和仁用杏间作谷子模式明显降低了叶绿素a/b值,而仁用杏间作大豆模式效果不明显;3种间作模式均不同程度降低了Fo,提高了Fm,Fv/Fm和Fv/Fo,其中以仁用杏间作花生和仁用杏间作谷子模式效果为好,仁用杏间作大豆模式次之。The effects of the model of fruit and grain intercropping on the growth and chlorophyll fluorescence parameters of kernel-apricot in western Liaoning were studied.Field experiments were carried out with kernel-apricot as the research object.Four treatments of interplanting kernel-apricot with soybean,kernel-apricot with peanut,kernel-apricot with millet and single kernel-apricot were set up to investigate the effects of different interplanting modes on the growth rhythm of new shoots,photosynthetic pigment and chlorophyll fluorescence parameters of kernel-apricot.The results show that the content of chlorophyll a,chlorophyll b and total chlorophyll under interplanting pattern of kernel-apricot with soybean,kernel-apricot with peanut and kernel-apricot with millet showed tendency to ascend and then descend,the annual variation of chlorophyll a/b was from increase to decrease,and then from decrease to increase;The three intercropping all improved the content of chlorophyll a,chlorophyll b and chlorophyll.Meanwhile,the intercropping of kernel pricot-peanut and kernel apricot-millet all made the chlorophyll a/b down significantly,but interplant of soybean had little effect;The three intercropping all reduced Fo of the three intercropping in different degrees,and increased Fm,Fv/Fm,Fv/Fo.Among them,the effects of intercropping kernel-apricot-peanut and intercropping kernel-apricot-millet were the best,followed as tintercropping kernelapricot-soybean.
