Led Plant Growth Lamp Factory To Strengthen Roots, Encourage, Regulate Flowering, Color, Fruit Maturity, Color, Improve Taste And Quality Role!

- Aug 06, 2019-

LED plant growth lamp is a kind of artificial light source which takes LED (light-emitting diode) as the light source to meet the light conditions needed by plant photosynthesis. Classification by type, belong to the third generation of plant fill light lamps!

In the absence of sunlight, the lamps act as daylight, allowing plants to grow normally or better.

This kind of lamp has the function of strengthening roots, encouraging, regulating flowering period and color, promoting fruit ripening and coloring, improving taste and quality.

The principle of

Light environment is one of the most important physical environmental factors for plant growth and development. Controlling plant morphology by light quality regulation is an important technique in the field of facility cultivation. Plant growth lamp is more environmentally friendly and energy-saving. LED plant lamp provides photosynthesis to plants, promotes plant growth, reduces the time of flowering and fruit, and improves production. In the modernization construction, it is the crop indispensable product.

Characteristics 

The wavelength types are abundant and coincide with the spectral range of plant light synthesis and light morphogenesis. The spectrum wave width is half wide and narrow, which can be combined to obtain pure monochromatic light and composite spectrum according to needs. It can focus light at specific wavelengths on crops evenly; It can not only regulate the flowering and fruiting of crops, but also control plant height and plant nutrients. The system has low heat and small space, and can be used in the multi-layer cultivation three-dimensional combination system, realizing low heat load and miniaturization of production space.

application

As the fourth generation of new lighting source, LED has many different characteristics from other electric light sources, which makes it the first choice of energy-saving and environment-friendly light source. Leds applied in the field of plant culture also show the following characteristics: the wavelength types are abundant, and exactly coincide with the spectral range of plant light synthesis and light morphogenesis; The spectrum wave width is half wide and narrow, which can be combined to obtain pure monochromatic light and composite spectrum according to needs. It can focus light at specific wavelengths on crops evenly; It can not only regulate the flowering and fruiting of crops, but also control plant height and plant nutrients. The system has low heat and small space, which can be used in multi-layer cultivation stereoscopic combination system, realizing low heat load and miniaturization of production space. In addition, its exceptional durability also reduces operating costs. Due to these outstanding characteristics, LED is very suitable for plant cultivation in controllable facility environment, such as plant tissue culture, facility horticulture and factory seedling cultivation, and aerospace ecological life and protection system.

use

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 cultivation does not use fertilizers at all, but what can be used are organic fertilizers, such as farm manure, mineral fertilizer and biological fungus fertilizer after the high-temperature fermentation and harmless treatment. Due to the limitation of this kind of fertilization, the growth cycle of plants must be affected and the current market demand appears to be in short supply. Therefore, shortening the production cycle is one of the methods.

LED plant lamp helps shorten the growth cycle of plants, because the light source of this kind of lamp is mainly composed of red and blue light source, which adopts the most sensitive light band of plants. The wavelength of red light is 620-630nm and 640-660nm, while 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, the development of organic farming is an opportunity for more and more producers.

Lighting technology for facility horticulture is mainly applied in two aspects:

As a supplementary illumination for photosynthesis of plants when the amount of sunlight is low or the duration of sunlight is short;

Second, as the induction lighting of plant photoperiod and photophaptic formation.

1. Traditional artificial light source produces too much heat. For example, if LED supplementary lighting and hydroponic system are adopted, the air can be recycled, too much heat and water can be removed, and electric energy can be efficiently converted into effective photosynthetic radiation and finally converted into plant substances. Studies have shown that the growth rate and photosynthetic rate of lettuce can be increased by more than 20% by using LED lighting, and it is feasible to use LED in plant factories.

Compared with fluorescent lamps, LED light with mixed wavelength can significantly promote the growth and development of spinach, radish and lettuce, and improve morphological indicators. It can make the maximum bioaccumulation of beet, the most significant accumulation of betaine in hair root, and produce the highest accumulation of sugar and starch in hair root.

Compared with the metal halide lamp, the anatomical morphology of the stems and leaves of the pepper and Perilla plants growing under the wavelength LED changed significantly, and the photosynthetic rate of the plants increased with the increase of light density. The combined wavelength LED LED to an increase in stomata in both marigold and sage plants.

2. LED is used as the induction lighting for plant photoperiod and light morphogenesis

Specific wavelength LED can affect the flowering time, quality and flowering duration of plants. Certain wavelengths of LED can improve the number of flower buds and flowering plants; Certain wavelengths of LED can reduce the floral response, regulate the length of pedicel and flowering period, which is conducive to the production and marketing of cut flowers. Thus it can be seen that the flowering and subsequent growth of plants can be regulated by LED regulation.

3. LED application in space ecological health protection system research

The establishment of Controlled Ecological Life SupportSystem (CELSS) is the fundamental way to solve the problem of long-term manned space Life guarantee. Cultivation of higher plants is an important element of CELSS, and one of its keys is illumination.

Based on the special requirements of space environment, the light source used in space higher plant cultivation must have the characteristics of high luminous efficiency, output light wave suitable for plant photosynthesis and morphogenesis, small size, light weight, long life, high safety and reliability record and no environmental pollution. Compared with other light sources such as cold white fluorescent lamp, high pressure sodium lamp and metal halide lamp, LED can transform light energy into photosynthetic effective radiation more effectively. In addition, it has the characteristics of long life, small size, light weight and solid state, so in recent years, it has been paid more attention to in the ground and space plant cultivation. Studies have shown that LED lighting system can provide uniform spectral energy distribution, and its efficiency of converting electric energy into light required by plants is 520 times higher than that of metal halide lamp.
