【Objective】This paper aims to comprehensively and correctly understand the effects of different basal fertilizers on the growth and photosynthetic fluorescence effect on jujube,so that we can carry out scientific fertilization management.【Method】In 2016,jujube Huizao was picked as research object in the Gobi New Village.Four treatments were set up,such as the control( CK),fulvic acid( FA),decomposed sheep manure( O) and fulvic acid + manure( FA + O) to analyze he effects on photosynthetic characteristics and yield of different basal fertilizers.【Result】Compared with the control,( 1) the net photosynthetic rate and water use efficiency of Jujube leaves treated with three kinds of basal treatments increased;( 2) fulvic acid + manure was more favorable for the increase of juvenile electron transfer rate; The energy allocation strategy of red jujube leaves was mainly based on passive energy dissipation( 50%).( 3) The yield and jujube fruit number increased significantly treated by different basal fertilizers; The yield of jujube treated by fulvic acid,sheep manure,fulvic acid + sheep manure was increased by 13.4%,2.5% and 18.0% higher than the CK.In addition,fertilization of fulvic acid of sheep manure significantly increased the fruit weight of red jujube.【Conclusion】In summary,the application of fulvic acid and humic manure was more conducive to the growth,yield and photosynthesis accumulation of Jujube.
