Nanobubble Hydrogen Irrigation for Higher CBD Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for agricultural irrigation with hydrogen face challenges due to low solubility and rapid degradation of hydrogen in water, limiting its effectiveness in enhancing plant growth and increasing the concentration of compounds like Cannabidiol (CBD) in crops.
Innovation Solution
The use of nanobubble hydrogen-rich water (HRW-nano) is introduced, where hydrogen nanobubbles with sizes ranging from 20 to 1000 nm, preferably less than 200 nm, are generated and infused into irrigation water to increase the stability and concentration of dissolved hydrogen, thereby increasing CBD production in crops like Cannabis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional gas injection methods are used to irrigate crops with hydrogen, then the process is simple, but the solubility of hydrogen in water is low and hydrogen degrades rapidly
Solution Approach 1:
The invention segments hydrogen into nanoscale bubbles (20-1000 nm) rather than using conventional gas bubbles. This segmentation dramatically increases the total surface area of hydrogen in contact with water, enhancing mass transfer and dissolution while reducing degradation. The nanobubble generator divides hydrogen gas into numerous tiny bubbles that remain suspended longer and dissolve more effectively.
Solution Approach 2:
The invention changes the physical parameter of hydrogen bubble size from micrometer scale (conventional) to nanometer scale (20-1000 nm). This parameter change fundamentally alters the behavior of hydrogen in water, increasing solubility and stability. The nanoscale dimension allows hydrogen to overcome buoyancy forces more effectively and maintain prolonged contact with plant roots.
2Productivity
If conventional hydrogen gas injection is used, then the equipment is simple, but the effectiveness in enhancing plant growth and increasing CBD concentration is limited
Solution Approach 1:
By segmenting hydrogen into nanobubbles, the invention dramatically increases the effective surface area for mass transfer to plant roots. This segmentation enables more reliable and consistent delivery of hydrogen to the root zone, thereby enhancing plant growth and increasing CBD concentration with greater reliability than conventional methods.
Solution Approach 2:
The nanobubble generator acts as an intermediary device that transforms conventional hydrogen gas into nanoscale bubbles. This intermediary mechanism bridges the gap between simple gas injection and effective hydrogen delivery, enabling reliable enhancement of plant growth and CBD production through improved hydrogen solubility and stability.
3Duration of action of stationary object
If hydrogen is injected as conventional gas bubbles, then the method is straightforward, but the surface area to volume ratio is low resulting in rapid degradation
Solution Approach 1:
The invention segments hydrogen gas into nanoscale bubbles (20-1000 nm), which dramatically increases the total surface area to volume ratio. This segmentation prevents rapid degradation by creating numerous small bubbles that dissolve more uniformly and persist longer in the water column, extending the duration of hydrogen availability to plants.
Solution Approach 2:
By changing the bubble size parameter from conventional micrometer scale to nanometer scale, the invention fundamentally extends the duration of hydrogen dissolution. The nanoscale dimension reduces buoyancy forces and increases surface area, allowing hydrogen to remain dissolved longer and maintain effective concentrations throughout the irrigation period.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method results in a 20-40% increase in Cannabidiol (CBD) concentration in hemp plants, demonstrating improved growth and yield enhancement without the limitations of conventional hydrogen gas injection methods.
Implementation Method 1
The larger surface area allows for increased mass transfer. Hence, the concerns of low solubility of H2 and fast degradation of dissolved H2 in water may be resolved by applying the nanobubbles.
Implementation Method 2
Hydrogen is a strong reducing agent. Zhang et al, 'Hydrogen-rich water alleviates the toxicities of different stresses to mycelial growth in Hypsizygus marmoreus', AMB Express, 7(1), 107, 2017 discloses hydrogen enhances the antioxidant activities and decrease the reactive oxygen species (ROS) level in mycelia.
Implementation Method 3
Liu et al, 'Antioxidant activity of hydrogen nanobubbles in water with different reactive oxygen species both in vivo and in vitro', Langmuir, 34(39), 11878-11885, 2018 disclosed nanobubbles enhanced the antioxidant capacity of hydrogen water and nanobubbles hydrogen water can remove ROS (·OH, ClO-)
