摘要： 为了明确架设防雹网对葡萄光合的影响,选用网线粗度为0.5,0.6,0.7 mm,网眼规格为1.0 cm×1.0 cm、1.2 cm×1.2 cm、1.5 cm×1.5 cm的深绿、浅绿、白色聚乙烯网和铁丝网为研究对象,以无网葡萄园为对照,观测其对光照和葡萄光合速率的影响。结果表明:网线越粗对光照强度的影响越大,最大影响率为15.40%;网眼越小影响越大,但不同处理的平均光照强度仍在6万lx以上,不同颜色的聚乙烯网和铁丝网的影响率分别为11.31%,10.60%,10.32%,9.42%;网色越深对光照影响越大。不同规格防雹网对葡萄光合速率均无显著影响。综合分析,生产中可选用网线粗细为0.5 mm、网眼规格为1.0 cm×1.0 cm、1.2 cm×1.2 cm、1.5 cm×1.5 cm白色聚乙烯网。

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.
