Abstract:
In order to study the influence of different water treatments on fruit commodity rate，the 20-year-old Korla fragrant pear trees with similar growth were selected as test objects，and were divided into three groups.During young fruit period，the test objects were irrigated as 60%(RDI-1)，80%(RDI-2) and 100%(CK) of conventional irrigation water amount respectively.The commodity fruit rate in 2012-2014 of each group was analyzed.The results showed that the average hardness of pear under water regulation was lower than that of control，and the content of soluble solids was higher than that of control.The comprehensive commodity fruit rate was lower than normal irrigation，and the treatment with irrigation quota of 80% conventional irrigation water amount in young fruit period could save 5% of total water consumption in growth period，and both satisfied the fruit commodity rate and water use efficiency，could be to be popularized and applied.
