Description
Technical field
The present invention relates to agriculturals, Material Field, and in particular to a kind of high light transmission difference mist degree greenhouse special glass and its system
Make method.
Background technique
The green plants that Modern Greenhouse of Agriculture is mainly planted includes vegetables, fruit, flowers etc..Green plants utilizes the sun
Luminous energy assimilates carbon dioxide and water manufacture organic substance and the process for discharging oxygen, referred to as photosynthesis.Produced by photosynthesis
Organic matter be mainly carbohydrate, and give off energy.It was found that the growth of green plants whole dry weight, 92%~
96% directly from photosynthesis, and promoting photosynthetic effect is one of the key means for promoting yield.
Photosynthetic effect is evaluated by photosynthetic rate, photosynthetic rate typically refer to the unit time, unit leaf area two
The burst size of carbonoxide uptake or oxygen, the external factor for influencing photosynthetic rate mainly have luminous intensity, Xanthophyll cycle and light quality.Light
Photosynthetic limiting factor can be become according to deficiency, luminous energy surplus can also have an adverse effect to photosynthesis.Work as Photosynthetic
When the light received is more than the amount that can be utilized, the phenomenon that also photosynthetic rate being caused to reduce.Under dark condition, blade without
The release of photosynthesis, only respiration.With the increase of luminous intensity, photosynthetic rate can also be correspondinglyd increase；As a certain spy of arrival
When determining luminous intensity, the photosynthetic rate of blade is equal to respiratory rate, i.e. carbon dioxide absorption amount is equal to carbon dioxide releasing amount: when super
Certain light intensity is crossed, the increase of photosynthetic rate will turn slow.When reaching a certain light intensity, photosynthetic rate is not further added by, i.e., light is full
And point.
The illumination condition in earth different latitude region is different.Low latitudes illumination condition is strong, sunshine is strong, if not right
Crop carries out illumination protection, and photosynthetic efficiency can reduce, so as to cause the reduction of crop-planting efficiency；Similarly, the light of high latitude area
Glass poor according to condition, strong using itself reflectivity at this time, refringence is poor so as to cause light transmittance, can reduce crop reception
Luminous intensity, inhibit plant growth.Therefore it needs that different garden glasses is arranged according to different latitudes, illumination condition；Separately
Outside, the working environment of garden glass is very easy to lead to the abrasion of glass and breakage in outdoor, can further result in greenhouse and make
Object photosynthetic efficiency reduces.It solves the problems, such as that this method is usually to repair or replace glass, does so and waste manpower and material resources wealth
Power improves production cost, and reduces service efficiency.
What agricultural greenhouse used in the prior art is all simple glass, and light transmittance is low, without scattering function, reduces crop
Yield；Part greenhouse improves light transmittance using the glass for pasting anti-reflection film, but anti-reflection film is easy aging, in routine use and
Breakage is easy in cleaning process, translucent effect is poor, and does not have scattering function.
It can be seen that by the analysis to the prior art, it is desirable to provide a kind of light transmittance is high, can be according to different latitude
Illumination condition uses different glass type, and the greenhouse special glass for being hardly damaged, improving service life.
Summary of the invention
