Forchlorfenuron and Nitrogen Fertilizer Mixture for Bud Break
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for breaking bud dormancy in woody perennial plants, such as hydrogen cyanamide, are toxic and lead to adverse health effects and in-season phytotoxicity, while nitrogen-containing fertilizers are not as effective or consistent.
Innovation Solution
A composition comprising a mixture of forchlorfenuron and a nitrogen-containing fertilizer at a ratio from 1:0.3 to 1:3,000 is applied to promote and synchronize bud break, using a combination of forchlorfenuron and nitrogen-containing fertilizers like calcium ammonium nitrate, 15-0-0, 17-0-0, or 27-0-0 fertilizers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydrogen cyanamide is used to break bud dormancy, then bud break effectiveness is improved, but human health safety deteriorates due to high toxicity
Solution Approach 1:
The patent extracts and removes the toxic hydrogen cyanamide from the formulation, replacing it with a combination of forchlorfenuron and nitrogen-containing fertilizer that achieves similar or superior bud break effectiveness without the harmful toxicity effects on human health
Solution Approach 2:
The patent substitutes a safe, readily available combination of forchlorfenuron and nitrogen fertilizer for the expensive and hazardous hydrogen cyanamide, using common agricultural chemicals that are less toxic and more acceptable for widespread use
2Reliability
If hydrogen cyanamide is used to break bud dormancy, then bud break synchrony is improved, but plant health deteriorates due to in-season phytotoxicity
Solution Approach 1:
The patent removes hydrogen cyanamide from the application and replaces it with forchlorfenuron combined with nitrogen fertilizer, eliminating the phytotoxicity effects while preserving the ability to achieve synchronous bud break and flowering
Solution Approach 2:
The patent creates a composite formulation combining forchlorfenuron and nitrogen-containing fertilizer that produces synergistic effects, achieving effective and synchronous bud break without the harmful side effects of hydrogen cyanamide
3Productivity
If nitrogen containing fertilizer is used to promote bud break, then plant growth is improved, but bud break effectiveness deteriorates compared to hydrogen cyanamide
Solution Approach 1:
The patent merges forchlorfenuron and nitrogen-containing fertilizer into a single application formulation, combining the dormancy-breaking capabilities of forchlorfenuron with the growth-promoting effects of nitrogen fertilizer to achieve both effective bud break and enhanced plant growth
Solution Approach 2:
The patent formulates a composite product that integrates forchlorfenuron and nitrogen fertilizer, creating a synergistic effect where the combination achieves superior bud break effectiveness compared to nitrogen fertilizer alone, while simultaneously promoting plant growth
