Plant Protection Application Timing via Physiologic State Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for supplying plant protection products and growth regulators to plants are wasteful due to excessive application, as they do not account for the plants' receptivity and the time delay between application and effective absorption, leading to inefficient resource use.
Innovation Solution
A method that predicts the future physiologic state of plants using models and sensors to adjust the quantity of plant protection products and growth regulators based on the discrepancy between actual and theoretical states, considering the time delay for effective absorption and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plant protection products and growth regulators are supplied in excess to assure adequate effectiveness, then the reliability of plant protection is improved, but the loss of substance increases and resource efficiency deteriorates
Solution Approach 1:
The system performs preliminary actions by predicting the future physiologic state of plants before supplying plant protection products. Sensors continuously monitor plant parameters and the model predicts future plant receptivity, allowing the control apparatus to timing the supply of plant protection products to coincide with peak plant receptivity, thereby avoiding excess application and waste
Solution Approach 2:
The system implements feedback by continuously monitoring actual plant physiologic state through sensors and comparing it with the predicted state. The control apparatus adjusts the quantity and timing of plant protection product supply based on the discrepancy between actual and predicted plant receptivity, ensuring optimal effectiveness while minimizing waste
2Ease of operation
If plant protection products are supplied without considering time delay for absorption and processing, then the ease of operation is improved, but the manufacturing precision of application timing deteriorates
Solution Approach 1:
The system performs preliminary prediction of the plant's future physiologic state and absorption capacity before application. The model calculates the optimal timing considering the time delay for root absorption, transportation to target tissue, and processing, allowing precise timing without complex manual adjustment
Solution Approach 2:
The plant essentially performs the service of indicating its own receptivity state through measurable parameters (water uptake, transpiration, biomass). The system automatically detects these self-generated signals and uses them to timing the application, eliminating the need for external judgment or complex timing calculations by the operator

AI summary
The disclosure relates to a method of cultivating plants comprising supplying at a given time a quantity of a plant protection product and/or plant growth regulator to the plants, wherein said quantity is adapted based on a prediction of a physiologic state of the plants at a time in the future relative to the given time, and is compensated for a difference between an indication of the real physiologic state of the plants at a time in the past relative to the given time and a theoretical physiologic state of the plants for said time the past.
