Description
Technical field
The invention belongs to the technical field of LED light source and dendrobium candidum nursery intersection, be related specifically to a kind of method adopting LED light source to carry out dendrobium candidum nursery and plantation.
Background technology
Dendrobium candidum is the epiphytic important On behalf of plant of the orchid family, be listed in first of " Chinese nine immortal grass " from ancient times, there is high medical value, because it is nourishing Yin and clearing heat, moistening lung nourishing the stomach, protect liver improving eyesight, the pharmacological action such as antitumor, be called " medicine circle giant panda " by international medicinal plant circle.Again because the growth cycle of dendrobium candidum is slow, growing environment is severe, more make it have high scientific research value and economic worth.It grows in required condition, and " light " is wherein environmental factor the most rambunctious, is also the major way of energy source, serves crucial effect to the photosynthesis of plant to grow and metabolism etc.Further, different wave length and light of different nature for plant grow and quality component has different impacts.Such as: the impact of ultraviolet light on form and physiology course of 280-315nm is minimum; Though the ultraviolet light of 315-400nm is few by Chlorophyll absorption, affect photoinductive cycles, stop stem to extend; The blue light of 400-520nm: chlorophyll and carotenoid assimilation ratio maximum, photosynthesis is had the greatest impact; And the green glow of 520-610nm, the absorption ratio of pigment is not high, is usually wasted; The ruddiness of 610-720nm, Chlorophyll absorption rate is low, has remarkable impact to photosynthesis and photoinductive cycles; 720-1000nm far-red light and infrared light, absorption ratio is low, but irritation cell extends, and impact is bloomed and seed sprouting; And the light being greater than 1000nm is generally all converted into heat.
Traditional plant illumination many employings high-pressure mercury lamp is as lighting source, and light efficiency is high, but color is single, and surface temperature is higher, can not with plant close contact, be not therefore suitable for multilayer cultivation, universal along with along with fluorescent lamp since eighties of last century nineties, be eliminated use.The distinguishing feature of fluorescent lamp is that spectrum can change to a certain extent, lamp surface temperature decreases, efficiency is relatively high, and from the principal mode for plant illumination after the nineties in last century, particularly CCFL is wherein especially because slim pipe diameter is applied to all kinds of plant light compensation.Since 21 century, solid-state illumination starts the visual field entering the public, and white light LEDs is by proposing to carry out ordinary people family, and from initial high price, up till now inexpensive, performance constantly promotes, and price constantly declines, and therefore also applies to some extent in plant illumination field.Most researchers all adopts blue chip and red light chips combination to prepare the LED that can glow with blue light, or directly adopts blue-ray LED and red-light LED to be applied to different plant illumination according to different proportion collocation.Result shows, adopts the LED plant illumination precisely controlled more effectively can shorten the growth cycle of plant, improves the nutritive index of plant.But the price due to red light chips is more than 2-3 times of blue chip, and dual chip encapsulation mode itself has an increased the difficulty of technique, indirectly improves production cost, therefore constrains the application that chip adds the LED plant illumination device of chip mode simultaneously.
In order to overcome above deficiency, the present invention proposes a kind of employing fluorescent material and blue chip compound, manufacture equipment and the manufacture method of fluorescent material excitated type LED plant light source, red fluorescence powder is a kind of in aluminate substrate, vanadate matrix or nitride, more conventional high temperature solid-state method can be adopted to prepare, the price of every lamp pearl red fluorescence powder used is only 1/10th of red light chips, but can reach just the same, even better effect: adopt fluorescent material excitated type LED can provide wider spectrum, and more close between sunshine.And because the abundant species of fluorescent material, the adjustment of spectrum can be realized very easily, can be more prone to, accurately for different plant realizes spectrum customization.Final the present invention has also been applied in the middle of the tissue cultures of dendrobium candidum and the growth of dendrobium candidum.While not reducing dendrobium candidum functional component, shorten its growth cycle, increase its annual production.
Summary of the invention
The object of this invention is to provide a kind of method adopting LED light source to carry out dendrobium candidum nursery and plantation.
The present invention is by the following technical solutions:
Adopt LED light source to carry out a method for dendrobium candidum nursery and plantation, utilize red fluorescence powder and blue chip jointly to encapsulate the luminescent device obtaining LED, in order to provide light source when dendrobium candidum nursery and plantation.
The red fluorescence powder adopted is one or several in aluminate substrate, vanadate matrix or nitride substrate, and emission spectrum is between 600-660nm wave-length coverage, and excitation spectrum is in 440-470nm wave-length coverage.
When adopting fluorescent material and blue chip to be assembled into luminescent device, the quality proportioning of fluorescent material and organic silica gel is 1:(4-20) between.
In the spectrum of the LED light source made, the ratio of the integral area at the blue peak integral area of blue chip and the red peak of red fluorescence powder is 1:(5-10) between.
The present invention is when being packaged into LED plant growth light source, and light source is assembled into various light fixture as required, as one or several in LED flat lamp, LED straight lamp and LED flying saucer lamp.
During dendrobium candidum nursery of the present invention with fluorescent material excitated type LED for lighting source carries out tissue cultures to dendrobium candidum, periodicity of illumination is 12h/ days, and intensity of illumination photo-quantum efficiency represents, controls at 80-120 μm of ol/m
2between/s.Using banana 50-70g/L+ active carbon 0.1-1%+ glucose 10-100g/L as medium, under temperature 20-30 DEG C of condition, by cultivation cycle 40-45d, proliferating cycle 40-45d, strong sprout obtains dendrobium candidum seedling after 40-60d.
Be transplanted in culture matrix by cultivating the dendrobium candidum of emerging, adopt brandreth material to carry out adjustable assembling support for cultivating, long is 69cm, and wide is 23cm, and interlamellar spacing is 17cm.Install fluorescent material excitated type LED plant growth panel light of the present invention for every layer and carry out light filling irradiation to plant, periodicity of illumination is 12h/ days, and intensity of illumination photo-quantum efficiency represents, controls at 120-200 μm of ol/m
2between/s, cultivation temperature 20-35 DEG C.Every 120d observes and detects once, the change of record growing way and physical index change.
Experimental result shows, adopts LED plant growth lamp of the present invention can shorten the time 5-10 days of dendrobium candidum tissue cultivation; The result be applied in the growth of dendrobium candidum seedling shows: the plant leaf adopting the inventive method to obtain is greener, newborn root system is denser, rhizome part is obviously more sturdy, stem is up to arriving 15-28cm, stem external diameter reaches 1-2cm, effective raising intensity of illumination caters to the heliotropism of dendrobium candidum, adds active ingredient, can promote on a large scale.
