Description
Technical Field
The invention relates to the field of plant planting, in particular to an industrial hemp planting method and a plant planting lamp.
Background
Cannabis is a general term for cannabis flowers and contains various cannabinoids such as Tetrahydrocannabinol (THC), Cannabidiol (CBD), Tetrahydrocannabinoid (THCV) and Cannabigerol (CBG). The type of cannabis depends on the content of THC, and industrial cannabis (Hemp) is defined as a content of THC below 0.3%. CBD is currently the most widely used and legally recognized raw material on the market.
CBD is extracted from leaves of industrial hemp, and classified according to its use, into medical CBD and consumer CBD. The consumption type CBD can be added into food and beverage for eating, and the medical type CBD can be used for treating diseases such as epilepsy and Parkinson. At present, 80% of cannabis in China is used in the pharmaceutical industry, especially in the traditional Chinese medicine industry. Although mass production has been achieved, the CBD currently has severe capacity limitations, and the downstream market has not yet been fully opened. In addition, most of products circulated in the market are small in dosage, and g and mg are used as purchase units, so that a large number of buyer orders are rarely shown. The potential demand is strong, and according to the current research, the CBD cannabinoids extracted from industrial cannabis sativa have certain medical value, and can be used for preparing medicines for essentially improving a plurality of diseases, including anorexia, AIDS, epilepsy, Parkinson, brain tumor and the like. Meanwhile, CBD is often used in the medical field to treat and alleviate diseases such as neurological diseases, cardiovascular diseases, inflammation, neuropathic pain, etc., which are higher in the elderly population.
THC is extracted from the cannabis plant, mainly from the leaves and stems of cannabis, female flowers and seeds. Because THC is a mild hallucinogen, a person gets symptoms such as accelerated heartbeat, dizziness, paralysis, relaxation, sleepiness, hallucinations, auditory hallucinations, and cannabis with an excessive THC content is a raw material banned by many laws.
The existing industrial hemp is usually planted outdoors and naturally irradiated by sunlight, but the THC content of the industrial hemp in a natural planting state is increased when the CBD content is increased, and the THC content is too high and forbidden by law, so that the CBD content of the naturally planted industrial hemp is lower, and the medical value and the production benefit of the planted industrial hemp are reduced; in addition, because the climate change is large and day and night alternation exists, the illumination condition of the naturally planted industrial hemp is unstable, and the growth period is long.
Disclosure of Invention
The invention aims to provide an industrial hemp planting method and a plant planting lamp which are different from the traditional open type planting environment.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for planting industrial hemp in room or greenhouse (facility) comprises providing artificial light source and filling with CO2The sunshine cumulative quantity DLI is 40-60;
the light-emitting spectrum of the artificial light source is a continuous spectrum with the wavelength between 380nm and 780nm, and the wave bands are distributed as follows:
the artificial light source has four peak wavelengths, and the wavelengths of the four peak wavelengths are as follows:
| peak wavelength (nm) | 410±5 | 455±5 | 530±5 | 640±5 |
| Half wave width (nm) | 6-10 | 15-22 | 30-40 | 75-90 |
| Relative spectral power | 0.24-0.32 | 0.88-0.96 | 0.61-0.67 | 0.88-0.96 |
The CO is2The concentration of the gas was 750-14500 ppm.
Further, the bands of the artificial light source are distributed as follows:
the wavelengths of the four peak wavelengths are as follows:
further, said CO2The concentration of the gas is 1000-11000 ppm.
Furthermore, the intensity of the artificial light source is adjustable, so that the illumination intensity of the artificial light source on the crown surface of the industrial hemp leaf is kept at 600--2·s-1。
A plant growing lamp comprises an artificial light source, a heat dissipation module and a light-transmitting cover; the artificial light source adopts the artificial light source; the heat dissipation module comprises a heat dissipation bottom plate and a plurality of heat dissipation fins arranged at intervals; the radiating fins are detachably arranged at the upper end of the radiating bottom plate, and the radiating efficiency of the radiating module is adjusted by changing the number of the radiating fins; the artificial light source is arranged on the lower end face of the heat dissipation bottom plate; the light-transmitting cover is arranged at the lower end of the heat dissipation bottom plate and covers the artificial light source.
Furthermore, a plurality of radiating grooves are arranged on the upper end surface of the radiating bottom plate at intervals along the length direction of the radiating bottom plate; the lower end of the radiating fin is tightly inserted into the radiating groove from top to bottom, and the radiating fin is locked on the radiating bottom plate through a locking device.
Further, the locking device comprises a locking screw and a locking nut; the radiating bottom plate is transversely provided with a through hole communicated with the radiating groove, the lower end of the radiating fin is provided with a locking hole, and the locking screw penetrates through the through hole and the locking hole and is tightly matched with the locking nut to lock the radiating fin on the radiating bottom plate.
Furthermore, a plurality of clamping grooves are formed in the upper end of the light-transmitting cover; a plurality of connecting clamping heads are fixed at the position where the lower end of the heat dissipation bottom plate is connected with the light-transmitting cover; the connecting clamping heads are tightly clamped into the clamping grooves to tightly install the light-transmitting cover on the heat dissipation bottom plate.
Further, a hollow sealing ring is fixed at the position where the lower end face of the radiating bottom plate is contacted with the light-transmitting cover; the hollow sealing ring is positioned on the inner side of the connecting chuck; a sealing groove is formed in the upper end of the light-transmitting cover; the hollow sealing ring is tightly embedded into the sealing groove.
Further, the artificial light source is an LED module.
After adopting the technical scheme, compared with the background technology, the invention has the following advantages:
1. the invention adopts a specific light formula and is supplemented with high-concentration CO2The gas environment stimulates the growth of industrial cannabis sativa and the accumulation of active ingredients, the content of Cannabidiol (CBD) can be effectively increased under the condition of inhibiting the content of Tetrahydrocannabinol (THC), the finally planted industrial cannabis sativa not only meets relevant legal regulations, but also can obtain higher content of Cannabidiol (CBD), and the medical value and the production benefit are high.
2. The invention adopts indoor or greenhouse (facility) to plant industrial hemp, which can prevent the industrial hemp from insect pest and reduce the use of pesticide; meanwhile, the water vapor generated by plant transpiration can be condensed and recycled indoors or in a greenhouse (facility), so that a small amount of water is not needed or only needed to be supplemented in the whole planting period, and the plant cultivation method is easy to manage.
