The application of science and technology to assist high-cash crops is a new trend in agriculture, especially the application of LED light source in plant growth, is a major breakthrough in recent years. Taiwan Institute of Industrial Research has found that replacing incandescent lights with LED lights for crop lighting at night can solve the yield problem caused by insufficient illumination, and can also achieve energy saving and electricity saving benefits, and increase farmers' income.
LED "Smart Greenhouse"
Taiwan industry institute development "greenhouse" wisdom, use wisdom of LED lighting control technology organic asparagus, and import the IoT environment automatic monitoring system, can automatically measure daily indoor light, air and soil temperature, humidity, conductivity, etc, and through the relevant data analysis, control the amount of light of LED lamps and lanterns to create the best asparagus plant light environment.
It has been proven that the total quality benefit can be increased by 32% through LED lighting. In the future, the software and hardware technology and production management mode of this demonstration field can be completely copied and expanded to other crop production, plant factories, simple greenhouse and other fields.
LED lighting shortens the number of days between planting and flowering
At the same time, Taiwan industry research institute and hsinchu xiangshan strawberry fields, using the LED light can reduces the number of days needed for planting to blossom, already can shorten at least 10 to 15 days, early harvest listed number increased perinatal, also can control the strawberry plant growth morphology, yield, quality, and suppress the occurrence of plant diseases and insect pests, the LED illumination technology value-added benefits, It also makes strawberry farming one of the high-value agriculture.
With the help of the institute, Wang Lishen, a grape farmer in Xihu Town, Changhua County, also applied LED night lighting devices to his vineyards. Because Taiwan area vineyards to shed planting, vines in shed branches, scattered leaves, the results, so the LED lamp must be from the bottom up irradiation, in order to play the maximum economic benefits; After constantly modifying the design and location of LED lamps, we have successfully developed modules that can replace incandescent lamps, saving considerable electricity costs for farmers.
LED customized filling light
At present, the intelligent LED lighting control technology of the institute has been used in the fields of bamboo shoots, asparagus, strawberries and grapes in Nantou, Hsinchu and Changhua in Taiwan, and has shown good planting results. LED light source can choose specific wavelength to adjust the amount of light and light quality, in line with the light wave required by plants, as a regulation of crop yield, yield and quality, and Taiwan's LED photoelectric industry has a complete supply chain and customized design ability, especially advanced agricultural planting technology is unique in the world, if combined with the two advantages, Will be able to create a world competitive high value added LED light applications and high quality agricultural products. Using the LED lights of Yizaizan, the Institute of Taiwan Engineering and Technology has lit up the path of high-value cash crops for farmers, and also made organic agriculture in Taiwan more transparent and bright.
Nantou Puli model
The first LED light from Taiwan Institute of Technology was used in the field of water bamboo shoots in Nantou Pu, so we put the LED light into the light control of water bamboo shoots in Nantou Pu, we take the light bulb way, we put the light bulb directly on top of the plants, so that the crops can get even light, so that the efficiency of photosynthesis is better.
This way of irradiation, power consumption significantly reduced by more than half, reduce the planting cost of farmers, LED lamps have the advantages of luminosity uniformity, no light harm, can achieve the purpose of increasing production, high efficiency, disease resistance and no light harm. It is not only bamboo shoots, but also the local organic asparagus from Taiwan. Even in the winter when the sunlight is not enough, the LED light source helps to make up the light, maintain the good quality and stable yield. The fresh, sweet and juicy asparagus is the result of the scientific and technological cooperation between the Jiujiufeng Organic Farm in Nantou and the Institute of Industrial Research.
Plant dedicated, as the fill light use of LED light source, a narrow spectrum of monochromatic light, such as red, yellow, orange can be any combination, in the growth of plants in different periods, to give scientific formula "spectrum", promote the growth of plant health, and solved the fluorescent lamp, incandescent lamp, halogen lamp and other traditional light source in the applications of plant high photosynthetic efficiency, low energy consumption, short life and so on.
Agricultural technology shows its power
Use LED semiconductor light source to do agricultural production, can also bring farmers great wealth? On September 1, the reporter interviewed in Nantaiqi Village, Shuangquan Town, Dali County, farmer Zhou Yizong gave a resounding answer: he sold five mu of greenhouse winter dates this year for 400,000 yuan, 80,000 yuan per mu of income, more than 4 times that of surrounding farmers. The secret is that he used LED semiconductor lighting, so that his Dongjujube half a month ahead of the market, sold such a good price.
"This time for the Zhou Yizong greenhouse winter jujube bud exhibition leaf period, flowering fruit set period and mature period of three key points, LED semiconductor lighting, so that the winter jujube mature period in advance half a month, the effect is very obvious." Zhao Duchuan, chief engineer of Yangling Shanhe Modern Agricultural Lighting Technology Development Co., Ltd., said the company made the LED semiconductor light, also known as "LED light fertilizer," used by Zhou Yizong.
"Don't underestimate the fact that it's only 15 days early." Zhou Yizong told reporters that his winter jujube in June in the latter half of maturity, preempted the market opportunity, per kilogram sold to 160 yuan is still in short supply, and other jujube farmers to now have not sold out. Zhou Yizong said he used 16 LED lights for his greenhouse, which cost a total of 30,000 yuan. "The yield is slightly increased, the taste is sweeter and crispy, and the market is half a month earlier. 30,000 yuan is a good deal!" At present, a lot of surrounding villagers have run to see true, ask curious, have to learn from him.
In Zhou Yizong's greenhouse, the reporter is really eye-opening, in addition to the "LED light fertilizer", he also bought the import of water and fertilizer integration, greenhouse heating, temperature and humidity adjustment display and other agricultural high-tech equipment. Zhou Yizong said with emotion: "only constantly charging learning, enrich the head, science and technology farming, is the modern farmers rich road!"
