Alternating Photoperiods for Soybean Yield Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for manipulating seed yield in short day plants, such as soybeans, are inefficient and require extensive resources, including the need for short day greenhouses that are difficult to maintain and costly, and do not allow for precise control over seed production timing and quantity.
Innovation Solution
A method involving alternating long day and short day growing conditions, along with controlled nutrient supply and soil volume to restrict vegetative growth and enhance flowering, allowing for precise manipulation of seed yield and generation time in plants like soybeans, cotton, rice, sugarcane, and strawberry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional short day greenhouse methods are used to manipulate seed yield, then seed production can be controlled, but the maintenance difficulty and cost increase significantly
Solution Approach 1:
The invention changes the photoperiod parameter from constant short day conditions to alternating long day and short day conditions. This parameter change enables seed yield manipulation in short day plants without requiring specialized greenhouse infrastructure, thereby resolving the contradiction between productivity control and ease of manufacture.
2Productivity
If traditional methods are used for seed production, then plants can grow naturally, but the generation time is extended and productivity is reduced
Solution Approach 1:
The invention applies periodic alternation between long day and short day conditions during plant growth. This periodic action accelerates the flowering and seed production process in short day plants, reducing generation time and increasing seed production efficiency compared to natural growth conditions.
3Quantity of substance
If more plants are grown to increase seed output, then total yield increases, but the resources and space requirements increase
Solution Approach 1:
The invention creates an optimized growth environment using alternating photoperiods that maximizes seed production per plant. This approach increases the effective productivity of each plant, allowing higher total seed output from fewer plants and less space, resolving the contradiction between quantity of substance and area of stationary object.
