LED fill in modern agriculture ecological difference

Spraying pesticides on vegetables, all kinds of crop pest diseases, endless food safety issues are worrying. Hunger breeds discontentment, "food basket" and the health of the people how to make people bound together in a common cause, eat more at ease, this has become the urgent problem of science and technology workers thinking.

Recently, the agricultural park of Shanghai semiconductor lighting engineering research center and Sunqiao Shanghai Municipal Science and Technology Commission subordinates to cooperate, the LED lighting system into vegetable greenhouses and conservatories, ecological fill the crops and kill pests research, to scientific and technological innovation to promote the healthy growth of crops.

LED is a new type of solid-state light source which has been developed rapidly in recent years. It has many advantages, such as environmental protection, energy saving, safety, long life, small size, maintenance free and so on. It has been widely used in many fields. In recent years, with the LED technology more and more mature, people began to introduce the LED lamp source in agricultural production. Compared to the currently used fluorescent lamp or HPS supplementary lighting system for artificial light source, LED light with adjustable light quality (red / Blue ratio or red / far red light ratio) can be adjusted, and the advantages of low cooling load allowed per unit area cultivation quantity, so the environmental control of agricultural production environment (such as in the closed plant tissue culture room, plant growth box) is a kind of artificial light is very suitable for the. And LED has begun to be used primarily for agricultural production, such as the U.S. space agency pioneered the use of LED in space agriculture.

The past dozen pesticide pest control of major hazards, and later switched to the black light trap, but not selective, all looking for light to catch insects to some extent destroyed the ecological balance. The test shows that LED monochromatic light of specific wavelengths for certain pests special attraction, Shanghai semiconductor lighting engineering research center and Sunqiao Park cooperative research, is to find more "perfect" combination. By adjusting the light to lure insects, pest control, agricultural products not only make more green, safe, energy-saving effect is quite obvious. According to estimates, LED light source is only about 20% of ordinary light source.

In the past, most of the seedlings of the factory were not afraid of the overcast and rainy sky, and the survival rate was low". Although by ordinary light source light "kaixiaozao" works, but high energy consumption and high cost. Now the application of LED light source light made of not only saving, but also about plant growth. Not long ago, Kuwait Sunqiao Agricultural Park princess to visit on the spot to buy LED ecological lights back.
