Using science and technology to assist high cash crops is a new trend in agriculture, especially the application of LED light sources in plant growth is a major breakthrough in recent years. The Taiwan Institute of Industry Research found that replacing LED incandescent lamps with LED lights as night lighting for crops can solve the problem of yield caused by insufficient light, and can also achieve the benefits of energy conservation and power saving, and increase farmers’ income.
At present, the intelligent LED lighting control technology of the Taiwan Industrial Research Institute has been adopted in Nantou, Hsinchu, Changhua, Taiwan’s white bamboo shoots, asparagus, strawberries and grapes, and has shown good planting results.
The LED light source can select a specific wavelength to adjust the light quantity and light quality to meet the light waves required by the plant. As a regulation of crop production period, yield, and quality, the LED optoelectronic industry in Taiwan has a complete supply chain and customized design capabilities, and advanced agricultural planting technology. In particular, it is unique in the world. If the advantages of the two are combined, it will create high-value-added LED light source applications and high-quality agricultural products with world competitiveness. With the use of LED lights, the Taiwan Industrial Research Institute lights up the road of high-value economic crops for farmers, and also makes the organic agriculture in Taiwan more transparent and bright.
The LED lamp of the Taiwan Institute of Technology was first tested in the white bamboo field in Puli, Nantou. The LED light was introduced into the white bamboo shoots in Puli, Nantou. The light was controlled by a bulb type. The bulb was directly placed above the plant so that the crop could receive uniform light, Make the efficiency of photosynthesis better.
This kind of irradiation can greatly reduce power consumption by more than half and reduce farmers’ planting costs. LED lights have the advantages of uniform brightness and no light damage, and can achieve the purpose of increasing yield, high efficiency, disease resistance, and no light damage.
Not only white bamboo shoots but local organic asparagus in Taiwan. Even in winter when there is insufficient sunlight, LED light sources to help fill up the light, maintain good quality and stable output, and become the best materials for five-star restaurant cuisine. The juicy asparagus is the result of scientific and technological cooperation between Nantou Jiujiufeng Organic Farm and the Industrial Research Institute.
The Taiwan Institute of Industry and Technology Research Institute develops a “smart greenhouse”, uses intelligent LED lighting control technology to grow organic asparagus, and introduces an IoT planting environment automatic monitoring system, which can automatically measure indoor light, air and soil temperature, humidity, electrical conductivity, and other data Through the analysis of relevant data, the light output of LED lamps is adjusted to create the best light environment for asparagus cultivation.
It has been confirmed that the total quality and efficiency can be improved by 32% through LED lighting. In the future, the software and hardware technology and production management model of this demonstration site can be completely copied and expanded to other crop production, plant factories, simple greenhouses, and other fields.
At the same time, the Taiwan Institute of Industry and Technology also cooperates with the Hsinchu Xiangshan Strawberry Garden. The use of LED light can shorten the number of days required for planting to flowering. It has been shortened by at least 10 to 15 days. Growth form, yield, quality, and inhibition of the occurrence of pests and diseases, and the added value of LED lighting technology have also made strawberry cultivation one of the high-value agriculture.
With the assistance of the Taiwan Institute of Industry and Technology, Wang Lishen, a farmer who grows grapes in Xihu Town, Changhua County, also applied LED night lighting devices to the vineyards.
Because the vineyards in Taiwan are planted in a shed, the branch of the vine shed leaves, and bear fruit on the shed. Therefore, LED lights must be illuminated from bottom to top in order to maximize the economic benefits. After constantly modifying the design and placement of LED lights Finally, successfully developed a module that can replace incandescent lamps, saving considerable electricity bills for farmers.
