Abstract
The invention discloses a method for promoting plant growth through an LED lamp. The method is implemented by giving LED far-red light irradiation to the plant after the photophase of the plant growth is over; the used light intensity is 5 to 20 Mu mol/m<2>*s<-1>, and the lighting time is 5 to 30 minutes. The method for promoting plant growth through LED far-red light has the advantages that the elongation growth of a hypocotyl and an internode of the plant can be improved, the strong seeding can be cultivated, the output of the vegetable crop can be increased, the commodity of flowers and plants is enhanced, and the growth cycle is reduced.
Description
1 technical field
The invention belongs to illuminating product in the application of agriculture field, relate to a kind of method of coming Promoting plant growth by the LED far-red light.
2 background technologies
Only occurring in nature affects one of most important factor of growth and development of plants.It not only provides radiant energy for photosynthesis of plant, but also as many physiology courses of the whole life cycle of ambient signal regulating plant.Such as seed germination, plant strain growth, flower bud differentiation and organ senescence etc.This process by light coordinate plant growth, differentiation and growth is called the photomorphogenesis of plant or claims the PHOTOCONTROL OF DEVELOPMENT effect.The process of photocontrol plant growth, growth and differentiation is the low energy reactions of light.Light plays signal function at this, and the character of signal is relevant with light wavelength, and plant corpus is experienced optical signal of different nature by different light receptors, and light quality all has regulating and controlling effect to growth, morphogenesis, photosynthesis, metabolism and the gene expression of plant.
Under the background that Present Global energy starved worry raises once again, energy savings is the important problem that we shall face future, at lighting field, the application of LED luminous product is just attracting common people's sight, LED is as a kind of novel green light source product, must be the trend of future development, 21st century will enter the novel illumination light source epoch take LED as representative.LED be called as the 4th generation lighting source or green light source, have the characteristics such as energy-saving and environmental protection, the life-span is long, volume is little.Along with the raising of LED production technology and the continuous decline of price thereof, LED uses the extensive concern that is subject to countries in the world in agricultural production.
Modern science and technology can allow plant in the situation that do not have the sun or sunshine deficiency, artificially create light source (simulated solar irradiation), allow the plant such as vegetables and flowers finish photosynthesis, promote growth.At present, worldwide plant husbandry, aquaculture mostly promote vegeto-animal growth by means of chemical classes antibiotic, growth regulator, agricultural chemicals etc., although successful often causes the adverse consequencess such as farmingization residually exceeds standard, environmental pollution.
For above prior art, the invention provides the method for a kind of safe and effective, ecological, environmental protective, nonhazardous, noresidue, free of contamination Promoting plant growth.
3 summary of the invention
The problem that the present invention solves is to provide a kind of method of coming Promoting plant growth by the LED far-red light, and its application can make vegetable seedling stem or hypocotyl rapid elongation, obtains in a short time the consistent good seedling strain of a large amount of specifications, promotes the ahead of time listing of some vegetables; On flowers are used, can promote the growth of fresh-cut scape, shorten growth cycle, improve quality and the commodity of cut-flower.
This invention is to be achieved through the following technical solutions:
A kind of method of coming Promoting plant growth by the LED lamp, the method are to shine to realize by give the LED far-red light when photophase of plant growth finishes, and the use light intensity is 5～200umol/m
2S
-1, light application time is 5～30min.
Described LED lamp is panel light, is mainly made by LED far-red light chip and aluminium alloy extrusions, and LED far-red light wave-length coverage is at 700～800nm, and maximum absorption wavelength is near 730nm.
Compared with prior art, the present invention has following useful technique effect:
1, provided by the inventionly come the method for Promoting plant growth to overcome the drawback that conventional method uses plant growth regulator that plant had side effects by the LED lamp, using up the regulating plant morphological development, is the method for a kind of safe and effective, ecological, environmental protective, nonhazardous, noresidue, free of contamination Promoting plant growth.
2, this LED lamp plate light quality provided by the invention is pure, energy-saving and environmental protecting, and manufacture craft is simple.Can carry out modification according to concrete environment for use, as make portable lamp bar, in the greenhouse, use on a large scale.
3, the method for this Promoting plant growth provided by the invention can achieve the goal under lower light quantity, and is economical and practical.
4 description of drawings
Fig. 1 is the structural representation of LED lamp of the present invention, is comprised of 1-LED red light chips, 2-aluminium alloy extrusions and 3-control system etc.
5 embodiments
Below in conjunction with embodiment the present invention is done to describe in further detail, described is to introduction of the present invention, and non-limiting.
Embodiment 1
Come the method for Promoting plant growth by the LED lamp, the plant among this embodiment is for cultivating the pumpkin seedling in the greenhouse, and concrete application method is:
Seedling medium is packed in the 50 holes dishes, after planting water permeable.Emerge and select uniform seedling after cotyledon flattens, be divided into two groups, every group of 15 strains are made as control group and processed group.
Every day, 18:30 gave LED far-red light irradiation 10min with the processed group seedling, and intensity of illumination is 5umol/m
2S
-1, subsequently processed group being carried out dark processing, control group is not done the LED far-red light and is processed when 18:30, directly enter dark processing.The next morning, 7:00 saw light with two groups of seedling.
Water and fertilizer management: every morning is watered one time of nutrition liquid (mg/l): 62NO
3-N, 15NH
1-N, 22P, 112K, 12Mg, 62Ca, 49S and 13Cl.
Concrete Contrast on effect is as shown in the table:
Table 1 contrast is compared (unit: mm) with processed group pumpkin seedling hypocotyl length
Annotate: being illustrated in different lowercases behind the column data in the table has utmost point significant difference on 1% level.
Plant among this embodiment is for cultivating the tomato seedling in climatic cabinate, and tomato seeds is " No. one, Jinpeng ", and concrete application method is:
Seedling medium is packed in the 72 holes dishes, after planting water permeable.Emerge and select uniform seedling after two weeks, be divided into two groups, every group of 15 strains are made as control group and processed group.
