When vegetable farmers grow vegetables, they need to choose suitable mesh materials according to the shading rate, so as to be conducive to the healthy growth of vegetables. Next, the shade net manufacturers choose the net material according to the shading rate to teach the vegetable farmers'friends.
Before choosing net material, vegetable growers need to know the shading rate of vegetables. When the sun shines directly in summer, the light intensity is about 60,000-100,000 lux, and the light saturation point of vegetables is 30,000-60,000 lux. Sunshade net manufacturers warn that if the light is too strong, the photosynthesis of vegetables will be affected, carbon dioxide absorption is blocked, respiratory intensity is too high, leading to photosynthesis noon break under natural conditions. Therefore, the appropriate shading rate of the net material for vegetable photosynthesis and growth has a very important role.
In order to ensure good photosynthesis of vegetables, vegetable farmers should choose the appropriate shading rate of mesh materials, not greedy for cheap and random selection. Sunshade net manufacturers warn that vegetables with lower light saturation point such as pepper can choose nets with higher shading rate, such as nets with shading rate of 50%-70%. For vegetables with higher light saturation point such as cucumber, nets with lower shading rate, such as nets with shading rate of 35%-50%, should be selected.
