LED as a new generation of light source, in addition to the characteristics of environmental protection and energy saving, compared to the agricultural sector is commonly used fluorescent or artificial light sources, such as high pressure sodium lamp has a light, light quality, and the adjustable, adjustable cooling load is low and allowed to improve cultivation quantity per unit area, etc, to the closed loop control of the environment of agricultural production, such as plant tissue were is a very suitable for artificial light.
At the same time in the cultivation, microalgae culture and other aspects of great application potential.
So what interesting changes will be made when LED lighting is applied to agriculture?
I. LED is used in greenhouse to supplement light
At present, the application of LED artificial light source in greenhouse production system is in the stage of development and promotion.
1. Pepper production (Netherlands)
1LED artificial light source 2LED artificial light source
2. Production of cut roses (Netherlands)
3LED plant light source 4LED plant lighting
3. LED combined with high-pressure sodium lamp for greenhouse lighting -- African chrysanthemum (Netherlands)
5LED with high pressure sodium lamp
4. Canopy lighting of greenhouse crops:
6 greenhouse crop canopy patching 7 greenhouse crop canopy patching
The necessity of canopy supplementation: improving the distribution of light in crop canopy and increasing canopy photosynthesis.
Irreplaceability of LED canopy light supplement: cold light source.
Such a supplement would increase tomato yield by about 15% (Holland)
2. Application of LED in microalgae production
Extracts can be used in cosmetics, food and health food industries.
1. Microalgae breeding (United States, energy)
Application of 8LED in microalgae production
2. Microalgae breeding (United States, functional food - health products)
Application of 9LED in microalgae production of 10LED in microalgae production
Application of LED in plant plant
Plants are not subject to regional restrictions;
Precise control of production;
Multi-layer planting, high space utilization;
High quality and other advantages.
Application of 11LED in plant plant and 12LED in plant plant
1. Plant factory and LED light source are integrated into the home
13 plant factories are integrated with LED light sources into homes
2. LED plant factory enters the hospital to assist in rehabilitation
14LED plant factory enters hospital to assist in rehabilitation
3. LED plant factories enter restaurants and supermarkets
15LED plant factory into restaurants, supermarkets
LED plant factory supermarket (direct harvest)
16LED plant factory supermarket
4. LED plant factory enters common areas such as reception room
18LED plant factory enters common areas such as reception room
5. LED plant cultivation enters the office
19LED plant cultivation into office
6. LED plant factory enters the school to popularize science education
20LED plant factory enters the school science popularization education 21LED plant factory into the school science popularization education
7. Combination of LED plant factories, shopping malls and urban buildings (vertical agriculture)
22LED plant factory is combined with shopping mall and city building
Iv. Application of LED in plant seedling plant
23LED is applied in plant seedling factory
LED has been applied in plant seedling plant.
V. application of LED in plant tissue culture
Application of 24LED in plant tissue culture application of 25LED in plant tissue culture application of 26LED in plant tissue culture
In the world, LED has been successfully applied in the field of plant tissue culture. In the early stage, LED has been applied in banana tissue culture, strawberry tissue culture and butterfly orchid tissue culture. At present, LED has been applied in many plant tissue culture.
6. Application of LED light source in livestock and poultry breeding field
Application of 27LED light source in livestock and poultry breeding field
Artificial light source plays an important role in large-scale breeding of livestock and poultry. In recent years, LED light source has been used to conduct experimental research on livestock and poultry breeding, and good results have been achieved.
The application of LED light source in aquaculture and fishery
Application of 28LED light source in aquaculture and fishery
Light catching fish became popular in the 8th century. For a long time, methods of fishing with fire or other forms of light have existed all over the world. Today these fishing methods are still a feature of modern fishing in many countries.
Application of 29LED light source in aquaculture and fishery
The factory production of aquaculture industry has become the future development trend.
Illumination is an important environmental factor affecting aquaculture.
8. Application of LED in pest control field -- light and insect lure
Application of 30LED in pest control field 31LED in pest control field
For many years, plant protection experts have been using light to trap insects, which has a good effect.
9. Application of LED light source in edible fungus field
Application of 33LED plant lamp in pest prevention
Edible fungus does not contain chlorophyll, does not carry on the photosynthesis;
However, the formation and development of edible fruiting body require artificial light source.
Application of 34LED light source in edible fungus field
Effects of light on the fruiting body: stimulating or inducing the formation of the primordium of the fruiting body;
Promoting differentiation of daughter entities;
To promote the formation and accumulation of daughter pigment;
Stimulate the cap thickening and stretching;
Inhibits extension of stalk;
The application of LED light source in other agricultural fields
Application of 35LED light source in other agricultural fields
11. Application of LED in aerospace agriculture
36LED is used in space agriculture
Xii. Skyscraper agriculture -- vision for future agricultural development
37 skyscraper agriculture
The combination of leds and solar power will play a big role.
