Nonmycorrhizal Fungal Composite for Plant Growth and Gene Containment
Solution Overview
Problem
Existing chemical fertilizers and pesticides, while effective, significantly impact agricultural and forest ecosystems, leading to environmental concerns. There is a need for plant cultivation materials and methods that minimize chemical use and prevent artificial diffusion of gene resources.
Innovation Solution
A plant growing composite comprising a liquid substrate and mycelium of a nonmycorrhizal functional filamentous fungus, derived from isolates collected from the planting site or its neighborhood. This composite is applied to growing plants before, after, or both before and after planting, enhancing growth and providing protection against diseases and pests while preventing artificial gene diffusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical fertilizers and pesticides are used, then plant growth promotion and disease protection are effective, but environmental ecosystems are significantly impacted
Solution Approach 1:
The patent converts harmful chemical substances into beneficial microbial agents. Specifically, it uses Trichoderma fungi (which can be considered beneficial) to replace chemical pesticides, and organic fertilizers to replace chemical fertilizers. The fungi provide disease protection through natural mechanisms like parasitism and competition, while organic fertilizers supply nutrients through decomposition processes, thereby eliminating the harmful environmental impacts of synthetic chemicals while maintaining agricultural effectiveness.
Solution Approach 2:
The patent changes the fundamental parameters of the cultivation system by switching from chemical-based inputs to biological-based inputs. This involves changing the source of nutrients (from synthetic chemicals to organic matter), the source of disease protection (from synthetic pesticides to microbial fungi), and the overall cultivation approach (from conventional chemical agriculture to eco-friendly biological agriculture). This parameter change resolves the contradiction by maintaining agricultural functionality while eliminating environmental harm.
2Reliability
If chemical fertilizers and pesticides are used, then plant cultivation is reliable and effective, but artificial diffusion of gene resources occurs
Solution Approach 1:
The patent converts the potentially harmful effect of gene diffusion into a beneficial localized microbial community establishment. By applying Trichoderma fungi and organic fertilizers, the patent creates a beneficial microbial ecosystem in the rhizosphere that provides disease protection and nutrient supply without causing artificial gene diffusion. The microbial organisms establish localized populations that function beneficially without the genetic contamination risks associated with chemical substances.
Solution Approach 2:
The patent employs self-service mechanisms through the use of indigenous or locally adapted microbial fungi and organic materials. The Trichoderma fungi and organic fertilizers are applied in a manner that allows them to establish self-sustaining populations in the soil and rhizosphere, providing continuous disease protection and nutrient supply without requiring external chemical inputs that could cause gene diffusion. The system serves itself through natural microbial processes rather than external chemical intervention.
3Productivity
If nonmycorrhizal filamentous fungi are used, then plant growth function is enhanced, but the fungi must be isolated and cultured carefully to prevent mycorrhiza formation
Solution Approach 1:
The patent applies local quality by specifying particular fungal species (Trichoderma genus) that have been selected for their nonmycorrhizal characteristics and beneficial properties. By choosing fungi that naturally exhibit nonmycorrhizal behavior, the patent ensures that the fungi provide plant growth promotion without forming mycorrhiza, thereby avoiding the need for complex isolation and culture procedures while maintaining the desired functional effects.
Solution Approach 2:
The patent achieves universality by using Trichoderma fungi that can perform multiple functions simultaneously: they provide disease protection through parasitism, promote plant growth through nutrient cycling, and maintain soil health through decomposition. This multi-functionality reduces the need for multiple separate microbial agents and simplifies the overall cultivation system, making the application process easier while maintaining enhanced plant growth functions.

AI summary
A plant growing composite produces intended effects and has measures against artificial diffusion of gene resources. The plant growing composite is applied to a growing plant before, after, or before and after the growing plant is planted. The growing plant is a plant to be planted at a planting site and grown artificially. The plant growing composite includes a liquid substrate, and a mycelium of a functional filamentous fungus that is nonmycorrhizal. The functional filamentous fungus has a function contributable to growth or a growing environment of the growing plant. The functional filamentous fungus is derived from a nonmycorrhizal filamentous fungus isolated from a sample collected from the planting site or a neighborhood of the planting site. A method for manufacturing the plant growing composite and a method for growing a plant with the plant growing composite are also described.
