LED plant growth lamp application and application

- May 20, 2019-


As the fourth generation of new lighting source, LED has many characteristics different from other electric light sources, which makes it the first choice of energy saving and environmental protection light source. Leds used in the field of plant culture also exhibit the following characteristics: a variety of wavelength types, just as plants the spectrum range of light synthesis and light morphogenesis is consistent;The spectral wave width is half width and narrow, pure monochromatic light and compound spectrum can be obtained by combining according to needs. Crops can be equally irradiated by concentrated light of a particular wavelength; It can not only adjust the flowering and fruiting of crops, but also control plant height and plant nutrition. The system has less heat and occupies less space, so it can be used in multi-layer cultivation system, realizing low heat load and miniaturization of production space. In addition, its strong durability also reduces operating costs. Due to these remarkable characteristics, LED is very suitable for plant cultivation in controlled facility environment, such as plant tissue culture, facility horticulture and factory seedling cultivation, and space ecological health protection system.


In the production of organic farming is a do not use chemical fertilizers, pesticides, growth regulators, also not use genetic engineering technology and ion radiation, but follow the law of nature, farming, physical and biological methods to improving soil fertility, the prevention and control plant diseases and insect pests, in order to obtain a safe agricultural production system of organisms and their products.

In fact, organic farming is not completely without fertilizer, but what can be used is organic fertilizer: after the harmless treatment of high-temperature fermentation of farm manure, mineral fertilizer, biological fertilizer and so on. Due to the limitation of this kind of fertilization, the growth cycle of plants is bound to be affected, and the current large demand in the market appears to be in short supply. Therefore, shortening the production cycle is one of the solutions.

LED plant light helps shorten the growth cycle of plants, because the light source of this kind of light is mainly composed of red and blue light sources, using the most sensitive light band of plants, red light wavelength is  620-630nm and 640-660nm,The wavelength of blue light is 450-460nm and 460-470nm.

These light sources are let plant to produce the best photosynthesis, the growth of the plant to get the best condition, the experiment and practical application show that, in addition to the plant in the lack of light time fill light, also make plants grow in the process of promoting multiple lateral branch and bud differentiation, speed up the root growth, accelerate plant carbohydrate synthesis and the synthesis of vitamin, shorten the growth cycle.

With the global demand for organic food increasing rapidly, it is an opportunity for more and more producers to develop organic farming
