KR-20260066443-A - Multi-stage hemp seedling control system

Abstract

The present invention aims to solve the problems of the prior art, and the objective of the present invention is to provide a multi-stage hemp seedling control system that maximizes the hemp production volume itself in a plant factory. Accordingly, a multi-stage hemp seedling control system according to one aspect of the present invention comprises: a sensor unit for detecting environmental conditions; a device unit for changing environmental conditions according to the detected value; and a cultivation unit for cultivating hemp. The cultivation unit is configured to form a plurality of cultivation stages, and the plurality of cultivation units are arranged in a plurality of adjacent rows to realize large-area cultivation. The device unit supplies nutrient solution or water to the cultivation unit, and the nutrient solution or water supplied to the cultivation unit is drained and moved in a direction perpendicular to the direction in which the cultivation unit forms a row.

Description

Multi-stage hemp seedling control system The present invention relates to a method for cultivating hemp, and more specifically, to a multi-stage hemp seedling control system for maximizing the growth of hemp in a closed plant factory environment, such as a container. A plant factory is a technology that produces crops in a closed environment within a closed space where the internal environment is controlled, and it can be described as an environmentally friendly production system aimed at providing safe food and year-round supply of ingredients. The advantages of such plant factories are cited as theoretically stable supply, unaffected by weather fluctuations such as cold or warm weather or typhoons, and free from damage caused by pathogens or pests; the ability to supply crops with consistent quality in terms of quantity, shape, taste, and nutritional value, as well as at stable prices. Furthermore, due to their high stability and the absence of pathogen or pest infestation, plant factories eliminate the need for spraying pesticides for prevention or control, and it is projected that safe, pesticide-free production will become possible. However, these plant factories have so far tended to be limited mainly to the cultivation of leafy vegetables. Therefore, it is expected that diversification of crop types will be necessary to ensure the sustainability of plant factories. In particular, if the cultivation of high-quality crops is successfully achieved, the popularization of plant factories is expected to be further accelerated. Hemp can be cited as an example of such high-quality crops. Hemp seeds contain a large amount of plant-based protein beneficial to the body, as well as 20 types of amino acids, including essential amino acids that the body cannot produce. Furthermore, they are rich in fiber, gamma-linolenic acid which helps balance hormones, omega-3 fatty acids which improve cardiovascular function, vitamin A, folic acid, and inorganic nutrients such as calcium and iron. In the United States and Canada, hemp seeds are utilized in various ways, such as being added to children's snacks and treats for the elderly. Time magazine in the U.S. selected hemp seeds as one of the top six supergrains. However, in many countries including Korea, since the 1960s, due to the hallucinogenic component (THC, intoxicating component) of hemp, regulations and penalties have been strict, so methods for cultivating hemp have not been officially studied. Accordingly, prior art document 1 discloses a processing technology for extracting high concentrations of cannabidiol (CBD) compounds from hemp, and prior art document 2 discloses a method and apparatus for collecting a mother body from hemp, but both are limited to research on subsequent stages based on the premise that hemp has been cultivated. Therefore, in order to extract components such as cannabinol (CBN), which have recently garnered attention, a fundamental change in hemp seedling cultivation methods is required first. Consequently, it is necessary to explore methods to maximize the growth rate of the hemp itself, and furthermore, to seek methods to maximize the growth rate of hemp in the form of automated plant factories.
