Abstract: "In order to clear the effect of hail suppression net on the light and photosynthetic rate of grapevines,the effect of dark green polyethylene net,light green polyethylene net,light green polyethylene net and wire net with 0.5,0.6 and 0.7 mm thickness and 1.0 cm×1.0 cm,1.2 cm×1.2 cm and 1.5 cm×1.5 cm mesh size on light and grape photosynthetic rate were observed.The result showed that the more thick cable had better impact on light.The greatest impact rate is 15.40%.The smallest mesh had greatest effect than the other but all the light intensity were above 60 000 lx.The impact rate of different colors of polyethylene net and wire net were 11.31%,10.60%,10.32%,9.42%,net deeper the color the greater the impact on the light.All the treatments had no significant effect on grapevines photosynthetic rate.The 1.0 cm×1.0 cm,1.2 cm×1.2 cm and 1.5 cm×1.5 cm with 0.5 mm thickness mesh white polyethylene net would be used in the yield.
