一、塑料遮阳网在蔬菜生产上应用的原理是什么? 因为遮阳网能防止强光、高温、暴雨、大风、霜冻以及鸟类等自然灾害,可以为蔬菜的生长发育改善环境条件。二、塑料遮阳网为什么能防止强光? 蔬菜生长需要光照进行光合作用,而对光照的要求是有一定范围的,在范围之内,光合作用强度随光照的增加而加大,超过这个范围,光合作用强度随光照的增加而下降。这个范围的起点叫光的补 First, the plastic shade net in the vegetable production is the application of the principle? Because the shade net to prevent glare, heat, rain, wind, frost and birds and other natural disasters, for the growth and development of vegetables to improve environmental conditions. Second, the plastic shade net Why prevent glare? Vegetable growth requires light for photosynthesis, and the requirements of the light is a certain range, within the scope of the photosynthesis intensity increases with the increase of light beyond this range, The photosynthesis intensity decreased with the increase of light. The starting point of this range is called light fill
