What This Patent Covers

The patent protects a cultivation method combining a first sheet covering the ground surface and a second sheet exposed above ground while buried in the soil, specifically designed to prevent water inflow into the root zone. This robust scope was secured after overcoming examiner rejections, demonstrating strong claim validity and high originality with limited prior art.

Competitive White Space

This patent primarily covers physical moisture control. White space exists in integrating advanced IoT sensors for automated, real-time irrigation adjustments, or developing complementary nutrient delivery systems that utilize the sheet infrastructure for precision fertilization.

Adjacent Application Opportunities
🌷 花卉栽培
High-Quality Flower Production System
In floriculture, specific stress management can be effective for controlling flowering time and vase life. Applying this technology could enable stable production of high-value flowers for export or rare varieties, potentially extending vase life by 20-30% or improving bloom consistency.
🌾 機能性作物栽培
Cultivation of High-Content Functional Crops
Drought stress is known to increase the content of specific functional compounds (e.g., polyphenols, vitamins) in crops. This technology could establish cultivation methods to efficiently enhance target compound content in functional vegetables or medicinal plants, potentially increasing active compound yield by 15-20%. This is expected to boost their value as health foods or pharmaceutical raw materials.
🏜️ 砂漠緑化・荒廃地再生
Water-Efficient Greening Technology
In desert regions or degraded lands with extremely limited water resources, this technology's moisture-blocking mechanism could be inversely applied to efficiently retain scarce water in the plant root zone. This minimizes loss from evaporation and infiltration, potentially reducing water consumption by up to 30% while promoting greening. This could significantly contribute to sustainable land use and environmental restoration.
Integration Roadmap — Estimated 15-Month Deployment
Phase 1: Introduction Study & Design
Duration: 2 months
Conduct field surveys, confirm consistency with cultivation plans, select sheet materials, and design installation for this technology. Efficient planning is possible by leveraging expertise from national research institutions.
Phase 2: Field Installation & Trial Cultivation
Duration: 4 months
Implement installation of the first and second sheets based on the design. Subsequently, establish a small trial area to evaluate the drought stress effect and growth status of the target fruit trees.
Phase 3: Full-Scale Operation & Effect Verification
Duration: 9 months
Based on trial cultivation results, expand the cultivation scale and begin full-scale operation. Analyze detailed quality data of harvested fruits (sugar content, acidity, flavor, etc.) and verify economic effects.
Technical Feasibility
This technology primarily involves physical installation of sheets on the ground surface and underground, suggesting high compatibility with existing agricultural machinery and civil engineering construction techniques. The patent abstract specifies concrete installation methods, such as 'a second sheet made of a long object, with one long side exposed from the ground surface and the other long side buried in the soil.' This indicates that it may not require large-scale capital investment or complex system development, potentially allowing for relatively easy introduction into existing orchards.
Success Scenario
Upon adopting this technology, companies could precisely manage drought stress for fruit trees, independent of weather conditions. This may lead to an average increase of 1-2 Brix in fruit sugar content, enabling higher market prices. Stable quality could also strengthen brand image and build consumer trust. Furthermore, optimizing irrigation and weeding could achieve an estimated 20% reduction in annual labor, allowing for optimal allocation of limited human resources.
