LED plant lighting applied to the future farm

Pink greenhouse is expected to make everyone eat

Crops are not just need LED grow light irradiation, we have to consider the LED grow light energy efficiency, efficient provision of crop growth in the process of light and temperature environment.

Different plants of different wavelengths, different colors of light, the reaction is not the same. For example, grapes need a longer sunshine time, LED lights in the red wavelength is a little more.

But strawberries need a large temperature difference, high heat, sunshine time is shorter, the proportion of Blu-ray is necessary to increase. According to the needs of different crops and growth environment to deploy the design, which also allows the technical threshold of light plants continue to increase.

The United States, Britain, the Netherlands and other countries of the rapid rise of the “pink greenhouse” is also an example.

Pink refers to the greenhouse pink light, is a combination of blue, red LED lights reflect each other after the two results.

Pink LED lights can not only improve the plant’s absorption of light, in the ideal lighting, temperature, humidity environment, plant growth rate can be increased by 20%, water consumption is also reduced by 90%.

But the price of pink greenhouse, but not too romantic. Although the next five years, LED prices may fall to 50%, but the overall cost of the greenhouse is still high.

Why should we actively create greenhouse farms?

FAO, the Food and Agriculture Organization of the United Nations, estimates that by 2050 the global population will reach 9.6 billion, an increase of more than 33 per cent.

But now there are still 2 billion people worldwide malnutrition. Want everyone to have food to eat, the global grain output must increase.

Unpredictable climate change, land, water supply is limited. Want to improve food production, you have to be prepared to go down the mountain to build a new farm.

We are entering agriculture 3.0 times. Through labor-intensive 1.0, machinery and fertilizer-led 2.0 times, agriculture 3.0 will be sensing, cloud, Internet of things such as technology-led stage. With the sensing technology, satellite images to monitor, data analysis of water, fertilizer consumption, are the future development trend of agriculture.

The emphasis is not on industrialization, but on improving productivity, sustainability and quality. The concept of vertical farms, which Dickson Despommier, a professor of public health at Columbia University put forward ten years ago, is also one of the solutions.

Vertical farms, is to use technology to create vertical overlap of agricultural greenhouse, save the crop production process need to consume land, water and fertilizer and other resources.

Ten years later, Japan has hundreds of vertical farms, the United States, Singapore, South Korea, Sweden and the Netherlands skyscrapers, you can also see the shadow of the vertical farm.
