In order to study the dust detaining capability Malus pumila,Juglans regia,Armeniaca vulgaris trees were chosen to measure and compare its content of dust retention,and the interrelation between leaf surface morphological structure and dust amount were explored.The results showed that the order from strong to weak in dust retaining capability in tested fruit tree leaves were Malus pumilaJuglans regiaArmeniaca vulgaris.The highest value of 5.295 mg·cm~(-2) was recorded in Malus pumila,and the lowest value of 2.697 mg·cm~(-2) was recorded in Armeniaca vulgaris.The dust amount increases with time prolonging(P0.01),the difference was extremely significant in the different heights dust retention amount(P0.01),the average leaf dust amount was 1 m[(1.716±0.800)mg·cm~(-2)]2 m[(1.217±0.355)mg·cm~(-2)]3 m[(0.950±0.362)mg·cm~(-2)].The electronic photos showed it′s significantly different in leaf surface micro-morphological structure.Malus pumila was coarse for villous feature,Armeniaca vulgaris was smooth,without villus,villous feature by observing the surface structure of the leaves.Due to different leaf surface micromorphological structures,the three fruit trees showed different dust detaining capability.The findings that the dust detaining capability was closely related with leaf surface features.
