Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively improve photosynthesis and growth of Dioscorea composita, a sun plant, under limited illumination conditions, particularly in areas with photovoltaic panels, as they interfere with photosynthetically active radiation, leading to inhibited growth and low production efficiency.
Innovation Solution
A compound mycorrhizal fungus growth promoting agent comprising Glomus mosseae, Streptomyces chartreusis, and plant growth-promoting rhizobacteria is developed, which is applied to Dioscorea composita seedlings to enhance photosynthesis and growth, increasing chlorophyll content and net photosynthetic rates, allowing for successful cultivation under photovoltaic panels with minimal impact on quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Dioscorea composita is planted under photovoltaic panels to increase land utilization, then land use efficiency is improved, but photosynthesis and plant growth are inhibited due to reduced light intensity
Solution Approach 1:
The patent introduces microorganisms (mycorrhizal fungi, plant growth-promoting rhizobacteria, and Streptomyces) as intermediaries between the photovoltaic panel environment and Dioscorea composita. These microorganisms produce plant hormones, enhance nutrient uptake, and stimulate photosynthesis, thereby mediating the adverse effects of reduced light intensity and enabling successful cultivation under panels
Solution Approach 2:
The patent applies microbial agents that change the physiological parameters of Dioscorea composita, including increasing chlorophyll content, enhancing photosynthetic enzyme activity, and promoting plant hormone synthesis. These parameter changes enable the plant to maintain growth under reduced illumination conditions
2Ease of operation
If conventional single-strain microbial agents are used to promote plant growth, then application simplicity is maintained, but effectiveness in improving photosynthesis under limited light is insufficient
Solution Approach 1:
The patent merges multiple beneficial microorganisms into a single compound preparation containing mycorrhizal fungi, plant growth-promoting rhizobacteria, and Streptomyces. This combination synergistically enhances photosynthesis promotion, nutrient uptake, and plant growth while maintaining ease of application as a single agent
Solution Approach 2:
The patent creates a composite microbial agent that integrates different types of microorganisms with complementary functions. The composite preparation includes fungi for symbiotic relationships, bacteria for growth promotion, and actinomycetes for antibiotic production and nutrient cycling, achieving enhanced reliability in improving photosynthesis under limited light
