Abstract:
Taking eight-year-old ‘Yali’ and ‘Xinli 7’ were used as the test materials,the combination of chemical reagents such as NAA，6-BA and ETH was used to design different chemical reagent treatment combinations.The ‘Yali’ and ‘Xinli 7’ were sprayed at different times after flowering，and the effects of different types and concentrations of chemical fruit thinning agents on the fruit setting rate and fruit quality of pears were studied,in order to provide reference for pear fruit management.The results showed that the best treatment effect was achieved by spraying 400 mg·L-1 ETH+100 mg·L-1 6-BA 7 days and 14 days after ‘Yali’ bloomed，with inflorescence fruit setting rates of 40.52% and 47.32% respectively，which were close to the 46.65% of manual thinning；while ‘Xinli 7’ was sprayed with 600 mg·L-1 ETH+10 mg·L-1 NAA.The treatment had the best effect，with inflorescence fruit setting rates of 32.33% and 35.30% respectively，which were close to 35.38% after manual thinning；and there was no significant difference in fruit quality after treatment with the two reagents and manual thinning.
