Description
Technical field
The present invention relates to field of agricultural cultivation, more particularly to a kind of LED suitable for agricultural automation plantation.
Background technology
Modern proportion of crop planting has used the means such as substantial amounts of agricultural chemicals, chemical fertilizer, hormone medicine and transgenosis, therefore
Also many diseases are brought for the mankind, there is data to show that agricultural chemicals and chemical substance trigger the possibility of cancer very big, steroids
Human developmental may also be triggered precocious for medicine and transgenosis and some destabilizing factors, while agricultural chemicals and chemical fertilizer are also to other
Biology brings destructive strike.
Existing organic healthy food plantation with common plastic house plastic sheeting and applies the implantation methods such as organic fertilizer substantially
Based on, early investment fund is big, and plant maintenance cost is high, and volume increase is general, so existing organic healthy food yields poorly, price
It is expensive, large-scale promotion can not be realized substantially.
Conversion film be it is a kind of by add light conversion agent realize light change film, it can will to plant growth be harmful to purple
Outer light is converted into the blue violet light useful to crop and blood orange light, or the non-absorbent green glow of plant and green-yellow light are converted into feux rouges.
I.e. by changing the light quality through conversion film, promote absorption of the plant to nutrients such as nitrogen, phosphorus, potassium, zinc, improve in blade
Photosynthate content raises, and promotes plant growth, while plays a part of reducing pest and disease damage.
The content of the invention
It is an object of the invention to provide a kind of LED, the present invention according to needed for clover shoot vegetable in growth course most
Good feux rouges and blue light ratio, help peasant to improve working condition, quality, the yield of plant can be improved, while growth period can be shortened,
Make its increase income, produce significant economic benefit and social benefit.
In order to realize first above-mentioned purpose, present invention employs following technical scheme：
A kind of LED, the LED include semiconductor wafer, and described semiconductor wafer is by epoxy encapsulation, described epoxy
