Abstract:

Taking the jujube which was direct seeding and orchard construction in Xinjiang Production and Construction Corps 14 group 224 company as materials,the four tree shapes were cylindrical shape,small canopy permanent line,small canopy permanent tree and middle trunk shape with three main branches were adopted,the relationship with four tree shapes,structural development,the fruit yield components and quality within four tree shapes were studied.The results showed that crown difference of 4 tree shapes was big,the maximum crown was small canopy shape.The main target yields were mother branch per plant,fruiting branch,No.of jujubes of fruiting branches,single fruit weight.Yield of 100¡«150 cm crown was significantly higher than that of 50¡«100 cm,yield per plant followed by small canopy permanent tree£¾small canopy permanent line£¾middle trunk shape with three main branches£¾cylindrical shape.Characteristics of fruit in 4 kinds of tree shape was related to layers,and increased with the fruit growth site,and no significant relationship with fruit growth orientation.The nutritional quality of different shapes and different layers had different fruit quality.Fruit sugar content,soluble solids content increased,organic acid decreased with fruit growth site increased.Fruit VC content of small crown shape was lower levels and that of cylindrical shape was high levels,and middle trunk shape with three main branches was higher.The nutritional quality of fruit in cylindrical shape was high£»quality of fruit in tree of small canopy permanent line was low.The fruit nutritional quality of north crown was low.ª¤
