Abstract:: Short shoot ‘Fuji’ apple was taken as the test materials,the effect of different volume fraction of biogas slurry spraying on the leaf on apple production quality and sucrose metabolism related enzyme activity in the course of mature were studied.The results showed that,biogas slurry spraying volume fraction of 75%,increased the fruit vitamin C,soluble sugar and titratable acid content and fruit shape index,improved the apple fruit quality,improved the production of apple,and controlled neither spray water or spray fertilizer production rate was the highest,reached to 13.7%,which could increase 44.5 kg per 667 m2.During the later ripe,the spray fertilizer treatment of sucrose synthase and sucrose phosphate synthase were higher than CK,with the biogas slurry spraying volume fraction increasing,sucrose content increased；sucrose content and the activity of sucrose synthase and sucrose phosphate synthase were extremely significant positive correlated,the correlation coefficient was 0.648,0.530 (P<0.01),on the basis of that,the synthesis of sucrose in the process of mature of ‘Fuji’ apples might be mainly regulated by sucrose synthase and sucrose phosphate synthase.And spraying biogas slurry on the leaf could increase its activity in the late mature,thus improved the sucrose content in apple fruit.
