Oz-E-Green Cynodon dactylon Dense Turf Mat Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turf grass varieties, such as 'Common' green couch, have coarser leaves, more open growth, profuse inflorescence production, and rapid lateral spread, making them less suitable for dense, low-maintenance applications like golf courses and residential lawns, where a dense mat and low mowing requirements are desired.
Innovation Solution
The 'Oz-E-Green' variety of Cynodon dactylon, characterized by a prostrate growth habit, fine leaf texture, short internode length, slow lateral extension, dense mat formation, low inflorescence production, and dark green color, is propagated vegetatively to maintain its unique traits, offering improved turf quality and reduced maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 'Common' green couch is used, then rapid lateral spread and profuse inflorescence production occur, but dense mat formation and low mowing requirements are not achieved
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a specific variety (Oz-E-Green) with genetically determined parameters of slow lateral extension and low inflorescence production, thereby achieving dense mat formation and low mowing requirements while maintaining controlled spread rate
2Quantity of substance
If profuse inflorescence production is observed in 'Common' green couch, then high reproductive output occurs, but low mowing requirements are not met
Solution Approach 1:
The patent changes the parameter of inflorescence production by selecting a variety (Oz-E-Green) with low inflorescence production characteristics, directly reducing mowing requirements while maintaining acceptable reproductive output for turf maintenance
3Speed
If coarse leaf texture and open growth are present in 'Common' green couch, then rapid growth occurs, but fine leaf texture and dense mat formation are not achieved
Solution Approach 1:
The patent applies parameter changes by selecting and propagating Oz-E-Green with fine leaf texture and prostrate growth habit parameters, achieving dense mat formation and improved turf quality while maintaining acceptable growth rate for turf establishment
