Abstract:
Taking the furrow irrigation pear trees at Aksu region in Xinjiang as the research object，the change laws of radiant energy interception and leaf area index at different growth stages,and their correlation were studied by HemiView canopy image analysis system under different growth period of pear.The results showed that the change of total radiant energy interception，direct radiant energy interception and scattered radiant energy interception were relatively stable，and the difference of them was not distinct.The order of radiant energy interception was total radiant energy interception＞direct radiant energy interception＞scattered radiant energy interception on the same day.LAI decreased during the pear growth period.Throughout the test period，radiant energy interception was mostly significant positive correlation with LAI under sunny conditions.But radiant energy interception had no significant correlation with LAI under overcast conditions.Scattered radiant energy interception had a great effect on LAI，nor did with direct radiant energy interception and LAI.There was no significant relationship between total radiant energy interception and LAI.
