Description

Induction method of hemp bud for CBD extraction {Hemp Hydroponics Method for CBD Extraction}

The present invention relates to a hydroponic cultivation method, and more particularly, to a method for inducing hemp buds, which is a hydroponic cultivation method for extracting hemp in a plant factory.

A plant factory is a technology that produces crops in a closed space in which the internal environment is controlled.

These plant factories theoretically have a stable supply, are not affected by weather changes such as cooling or riots, typhoons, and are not damaged by pathogens or pests. In addition, it is mentioned as an advantage that crops can be supplied at a stable price. In addition, since the plant factory has high stability and no invasion of pathogens or pests, it is not necessary to spray pesticides for their prevention and control, and it is expected that safe production without pesticides will be possible.

However, these plant factories tend to be limited to vegetable cultivation of leafy vegetables until now. Accordingly, it is expected that diversification of crop types is necessary to ensure the sustainability of plant factories. In particular, if the cultivation of high-quality crops is successful, it is expected that the popularization of plant factories will be accelerated.

Among these high-quality crops, hemp (hemp) can be cited as an example. In the case of hemp seed (seed), it contains a lot of vegetable protein that is good for our body and contains 20 kinds of amino acids, including essential amino acids that are not produced in the body, as well as gamma linolenic acid that helps balance hormones and improves cardiovascular function. Inorganic nutrients such as good omega 3·6 (fatty acid), vitamins A·B1·B2·B3·B6·D·E, folic acid, calcium, and iron, and fiber-rich hemp seeds are used as snacks for children and snacks for the elderly in the United States and Canada. It is used in a variety of ways, such as adding to The US <Time> selected hemp seeds as one of the six super grains.

Furthermore, Cannabidiol (CBD), which is extracted from hemp, is expected to affect the brain by preventing the breakdown of chemicals in the brain that affect pain, mood and mental function. Cannabidiol can also block some of the psychoactive (psychedelic) effects of delta-9-tetrahydrocannabinol (THC).

Currently, there is no domestically approved product containing cannabidiol, but for the purpose of self-treatment for rare and intractable treatment for which there is no alternative treatment in Korea, hemp-based medicines approved overseas can be imported and used. there is. In Korea, cannabidiol-containing medicines are orphan prescription medicines and cannot be obtained like general medicines. Individuals submit an application for handling approval, diagnosis, medical record, medical opinion, etc. Available through the center.

However, since the 1960s in many countries, including Korea, related regulations and punishments have been strict due to the hallucinogenic component (THC, intoxicating component) of hemp, so the method of cultivating hemp has not been officially studied. Accordingly, Prior Art Document 1 also discloses a processing technique for extracting high-concentration cannabidiol (CBD) compounds from hemp, and Prior Art Document 2 also discloses a method and apparatus for collecting parent bodies from hemp, but all of them Assuming that hemp has been cultivated, the study is limited to later stages.

By the way, in order to increase the yield of cannabidiol (CBD), which is the most issue, it is very important to induce buds. This is because the altitude of the extraction method and the induction of sufficient buds beforehand must be preceded. Accordingly, a specific cultivation method is required, but related research has been almost non-existent to date.

First, referring to FIGS. 1 to 3, the hemp bud induction method according to an embodiment of the present invention includes a seeding step of sowing hemp (S100), a seedling step of raising the seeded hemp (S200), and It includes a moving step of moving to redistribution (S300) and a growing step of growing the moved hemp in the cultivation unit 400 (S400).

In order to maximize the amount of CBD extraction, in the seeding step (S100), it is preferable to form a high humidity while warming the bottom of the cultivation tray, and the seedling step (S200) is a planting step (S210), 1st training step (S220), and 2 It consists of a chart training step (S230), and it is preferable to perform the training step of removing branches in this way a plurality of times.

In addition, in the seeding step (S100) and the seedling raising step (S200), seeding and seedling can be performed by a known conventional method. Due to the nature of hemp, the seeding step is performed for 12 to 16 days, and the seedling raising step is the seeding 5 It should be performed from week to week 7 to be in the most desirable state to enter the growth stage.

Then, through the movement step (S300), the growth step (S400) consists of a vegetative growth step (S210), a reproductive growth step (S220), and a bud browning step (S230). The reproductive growth step (S230) refers to a growth step in which vegetative growth is converted into reproductive growth. That is, the hemp bud induction method according to an embodiment of the present invention is characterized by maximizing bud induction by artificially converting vegetative growth into reproductive growth by optimizing environmental conditions. Then, when the set period has elapsed in the bud browning step (S230) in which the bud is browned, it is harvested.

Induction of hemp buds as described above is blocked from the external atmosphere and external light inside a place such as a container, and the internal hemp growth conditions are separately controlled. The hemp bird induction system 1000 for this purpose includes a sensor unit 100, a control unit 200, a device unit 300, a cultivation unit 400 in which hemp H is grown and grown, and a server 500, as shown in FIG. ), including

At this time, referring to FIG. 5, the sensor unit 100 detects the internal environmental conditions, and in more detail, the temperature sensor 110 for detecting the internal temperature, the humidity sensor 120 for detecting the internal humidity, and the internal It includes a CO2 sensor 130 that measures the CO2 concentration, and an illuminance sensor 160 that measures the internal illuminance applied to the light source and the hemp, and as shown, the flow sensor 140 that detects water supply and the nutrient solution An EC sensor 150 for determining the component may be further included.

At this time, it is preferable that the temperature sensor 110, humidity sensor 120, CO2 sensor 130, and illuminance sensor 160 are disposed in the gas atmosphere inside, and a plurality of them are arranged for each zone to obtain an average value. do. This is because when cultivation is performed in the form of a large-area container-type plant factory, a gradient may occur in the gas atmosphere of the internal space.

Meanwhile, the control unit 200 controls the device unit 300 according to the sensed value of the sensor unit 100 to optimize internal environmental conditions and growth conditions. In more detail, the control unit 200 includes an air conditioner 310, a light source 320, a dehumidifying unit 330, a ventilation unit 340, a local fan 350, a CO2 valve 360, and a water bottle. (370). The water pump 380 is controlled to control the overall temperature, air circulation, light source, and nutrient solution.

First, the air conditioner controls the ambient temperature in the growth step (S400). By the way, it is preferable that the air conditioner 310 forms the temperature of the vegetative growth step (S410) lower than the temperature of the reproductive growth step (S420). Furthermore, the temperature of the bud browning step (S430) is preferably formed smaller than that of the vegetative growth step (S410). This causes an artificial decrease in temperature to stop vegetative growth and cause the buds to initiate induced reproductive growth, rapidly browning the buds for harvest.

More specifically, the temperature of the vegetative growth step (S410) is formed at 25 to 29 ° C, and the temperature of the reproductive growth step (S420) is preferably formed at 26 to 30 ° C. In addition, the temperature of the vegetative growth step (S410) and the reproductive growth step (S420) is preferably formed higher than that of the dark season.

On the other hand, since a large-capacity plant factory needs to remove a wide range of moisture, the dehumidifying unit 330 serves to remove moisture generated by transpiration of crops. However, in the method of inducing hemp buds according to the present invention, since rapid seasonal changes must be suggested to hemp along with temperature control, it is preferable that the humidity in the vegetative growth step (S410) is smaller than that in the reproductive growth step (S420). .

More specifically, the humidity of the vegetative growth step (S410) is formed at 60 to 80%, and the humidity of the reproductive growth step (S420) is preferably formed at 65 to 85%. In addition, it is preferable that the humidity of the vegetative growth step (S410) and the reproductive growth step (S420), such as temperature control, is higher than that of the dark season.

Meanwhile, the light source 320 may include a plurality of LEDs that apply light. At this time, the LED is preferably used by mixing red-based light to compensate for red-based light, which is a wavelength peak lacking in normal white light and normal white light.

In addition, at this time, when the light emitted by using the blue-based bare chip is excited by the phosphor and expresses white, the blue-based wavelength peak is struck and can be used to supplement the blue-based light required for photosynthesis. In the case where the wavelength peak of the bare chip itself is light separated from the blue series, it is also desirable to add another LED separately emitting blue light. Accordingly, the growth rate can be increased by allowing the chlorophyll of crops to mainly absorb blue-violet light (430-460 nm) and red light (630-680 nm).

At this time, the light source 320 applies different values of the photosynthetic photon flux density (PPDF, µmol·s-1·m-2) in the vegetative growth step (S410) and the reproductive growth step (S420). In more detail, the light source 320 applies light so that the value of the photosynthetic photon flux density in the reproductive growth step (S420) increases by 35 to 60% compared to the vegetative growth step (S410). If it is less than 35%, this is because the time at which the bud is induced is not remarkably fast despite the above changes in temperature and humidity, and if it exceeds 60%, it is because power is wasted due to light saturation.

On the other hand, the ventilation unit 340 is disposed on the upper side to guide the air discharged from the air conditioner 310 to the other side. As shown in FIG. 7 , the first ventilation unit 340 serves to induce air from one side to the other (right direction in FIG. 7 ). The local fan 350 is preferably installed on the cultivation unit 400 to assist in inducing air. The temperature and humidity gradients are minimized by the action of the ventilation unit 340 and the local fan 350 as described above.

On the other hand, in order to further maximize the bird induction beyond the above temperature and humidity control, CO2 control must be performed together. The CO2 valve 360 makes the CO2 concentration in the atmosphere different from each other in the vegetative growth step (S410) and the reproductive growth step (S420). In more detail, the CO2 concentration in the vegetative growth step (S410) is formed smaller than the CO2 concentration in the reproductive growth step (S420). More specifically, in the reproductive growth stage, it is preferable to increase the CO2 concentration by 25 to 70%. As the net photosynthetic rate is temporarily promoted according to the sudden change in CO2 concentration, the bud induction rate is greatly increased.

Furthermore, changes in the composition of the nutrient solution also have a great effect on the induction of buds. Accordingly, the EC sensor 150 of the watering can 370 detects the nitrogen content of the nutrient solution. It is more preferable that the nitrogen content in the nutrient solution is larger in the vegetative growth step (S410). In addition, it is preferable that the components of the nutrient solution are formed differently even in the above-described seeding step (S100) and other steps.

On the other hand, even in the case of irrigation amount, it affects bud induction. Therefore, it is preferable that the water pump 380 is formed with different amounts of water supplied in the vegetative growth step (S410) and the reproductive growth step (S420). More specifically, in the vegetative growth step (S410), it is preferable to relatively reduce the amount of water supplied in order to increase the growth of the roots, and to supply sufficient water in the reproductive growth step (S420).

Meanwhile, the flow sensor 140 detects the flow rate of the cultivation unit 400, and the water pump preferably has a moisture content of the cultivation unit 400 of 45 to 65%. If it is less than 45, it is because root growth is hindered, and if it is more than 65, oxygen supply is blocked and it acts as an obstacle to growth.

On the other hand, it is preferable to control the vegetative growth stage or reproductive growth stage at 3 to 5 weeks in view of the general growth rate of hemp. In addition, in this case, it is good to judge that the reproductive growth stage starts when the size of the hemp is 60 to 80 cm. In addition, after the bud browning step, when harvesting is performed before 10 to 20 days have elapsed, the highest CBD content is obtained.

In the above specification and drawings, preferred embodiments of the present invention have been disclosed, and although specific terms have been used, they are only used in a general sense to easily explain the technical content of the present invention and help understanding of the present invention, and the present invention It is not intended to limit the scope of It is obvious to those skilled in the art that other modified examples based on the technical spirit of the present invention can be implemented in addition to the embodiments disclosed herein.
