Abstract
The invention discloses a method for carrying out lettuce indoor production by utilizing a light source of an LED (Light-emitting Diode) and belongs to the technical field of vegetables. The method comprises the following steps: after a lettuce seed is sprouted for 2-3 days, directly seeding on the substrate surface of square sponge, hydroponically culturing in nutrient solution till 2 main leaves are generated, then seeding into a planting hole in a foam board floating in a hydroponic tank after a lettuce young seedling is wrapped by the sponge, putting under the LED with a ratio of blue, red and yellow being 8:1:1 and hydroponically culturing for 40 days in the nutrient solution. The light source of the LED with the ratio of blue, red and yellow being 8:1:1 is most suitable for the growth of lettuce. The method has the advantages of simplicity in operation, rapid plant growth, strong plant, energy saving, environment protection and the like and can be applied to industrialized production of indoor rapid seedling nursery, cultivation and planting of the lettuce and other fields.
Description
Technical field
The present invention relates to a kind of method of utilizing LED light source to carry out romaine lettuce indoor production, belong to vegetables technical field.
Background technology
Water planting vegetables, refer to that most of root growth is in nutrient solution liquid layer layer, only by nutrient solution, for it, provide the vegetables of cultivating under traditional soil cultivation form that are different from of moisture, nutrient, oxygen.The water planting vegetable growth cycle is short, is rich in the necessary vitamin of multiple human body and mineral matter.Romaine lettuce another name lettuce, belongs to composite family Lactuca plant, is the main breed of water planting vegetables.Romaine lettuce nutritive value is higher, mainly take and eats raw as main, is cold and dressed with sauce salad, the indispensable vegetables of hamburger.Common Vegetables in becoming Common People again in recent years in China big city, can eat raw, also can quick-fried, and mutton cooked in a chafing pot.But at the light source of romaine lettuce indoor production, there is no the technology of mature and reliable aspect providing.
Only occurring in nature affects plant growth and grows one of most important envirment factor, and it not only provides energy for photosynthesis of plant, but also as the whole life cycle of ambient signal regulating plant.Fast development along with scientific and technical progress and agricultural and biological industry, plant has broken through the restriction of simple dependence sunshine to the utilization of efficient light, artificial light source replaces or the deficiency of supplementing lamp has become the important means that environment is controlled growth and development of plants.Artificial light source in agricultural and biological field use mainly contains fluorescent lamp, incandescent lamp, sodium vapor lamp and dysprosium lamp etc. for a long time, wherein high-pressure mercury lamp and dysprosium lamp are luminous efficiency and the higher light source of efficient light combined coefficient, but power consumption is large, emission spectrum can not match with the photosynthesis absorption spectrum of plant well, does light filling efficiency low; And produce a lot of thermal radiation, and can not plant be approached and be irradiated, not high to plant growth light stimulus efficiency, do artificial light source cost very high.Therefore, introduce that energy-conservation, good luminous performance, quantity of heat production are low, the new type light source of long service life, to improving utilization rate of electrical in plant factor and space availability ratio, reduction power consumption cost is significant.
Novel high-efficiency and energy-saving light source-light emitting diode (light-emitting diodes, LED), receives publicity day by day as a kind of semiconductor light sources that can be used for plant irradiation.Compared to the fluorescent lamp or the high-pressure mercury lamp that generally use at present, LED a kind ofly can be transformed into electric energy the device of electromagnetic radiation effectively, has the following advantages: use direct current, supply voltage is lower; Volume is little, compact conformation, stable performance; Wavelength is fixed; Cold light source, can irradiation at short distance plant, improves space availability ratio; Efficient energy-saving, high-photoelectric transformation efficiency, the low cooling load of generating heat is little, and power consumption is that power consumption is only 1/8th of incandescent lamp, 1/2nd of fluorescent lamp; Utility rate of luminous energy can reach 80%～90% also can realize control separately to different light medium and luminous intensity, and energy-saving effect is remarkable; Light quantity capable of regulating, can improve unit are cultivation amount; Allow to provide high frequency intermittently to optical mode; Light quality capable of regulating, can send the narrower monochromatic light of light wave, but also can need any combination according to difference; Shock-resistant, be difficult for fragmentation, not mercurous, pollution-free, discarded object recoverable, meets agricultural production reality; Life-span is long, and be the decades of times of ordinary light source its service life, and the durability of extra-heavy has reduced operating cost.Therefore, utilize the performance characteristics of LED to develop the required artificial light source of plant and will greatly improve its optical energy utilization efficiency.
This method has been explored and has been adopted LED light source to carry out the test of romaine lettuce indoor production, set up complete feasible test method, operating procedure is simple, and test effect is stable, clear, therefore no matter in actual production, scientific research, detection and student's test, can well be applied.
