Innovation Solution
A non-chemical simulated environment cultivation method involving site selection with specific shade and slope conditions, use of organic and microbial fertilizers, and biological pesticides to enhance disease resistance and yield, mimicking konjac's natural habitat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large-scale artificial planting is implemented to increase production capacity, then productivity is improved, but disease incidence increases and quality deteriorates
Solution Approach 1:
The patent changes environmental parameters by selecting specific shade degrees (30%-90%) and slope angles (0°-30°) to create optimal growing conditions that enhance disease resistance while maintaining high productivity. This parameter optimization allows large-scale cultivation without sacrificing reliability.
Solution Approach 2:
The patent introduces beneficial microorganisms (Penicillium glabrum and Bacillus subtilis) as intermediary agents that mediate between the konjac plant and harmful diseases. These microorganisms act as protective intermediaries that prevent disease infection while allowing continued high-yield production.
2Productivity
If chemical fertilizers and pesticides are used to increase yield, then productivity is improved, but harmful factors are introduced that reduce quality and cause environmental damage
Solution Approach 1:
The patent converts harmful chemical fertilizers and pesticides into beneficial biological alternatives. By using organic fertilizers and beneficial microorganisms, the system transforms potential harm into benefit, achieving high yield without chemical pollution while improving soil health and konjac quality.
Solution Approach 2:
The patent enables the konjac cultivation system to serve itself by utilizing natural ecological processes. Beneficial microorganisms naturally protect the plants from diseases, and organic matter naturally fertilizes the soil, eliminating the need for external chemical inputs while maintaining high productivity.
3Productivity
If traditional high-yield agricultural model is adopted to maximize output, then productivity is improved, but breeding cycle length increases and reproduction rate decreases
Solution Approach 1:
The patent introduces dynamic management practices including monthly applications of beneficial microorganisms and adaptive organic fertilization that optimize the breeding cycle. This dynamic approach accelerates reproduction rates while maintaining high yield, preventing the system from becoming static and inefficient.

AI summary
A cultivation method of konjac under non-chemical simulated environment includes: (1), site selection: a forest land with a shade degree in a range of 30% to 90% and a slope of 0° to 30° is selected, roots 1.5 to 2.0 meters away from a tree trunk are plowed and broken, followed by fertilizing, and forming ridges for planting; (2), planning: a planting depth of konjac seed corms is 3 to 5 times a height of the konjac seed corms, then a Penicillium glabrum agent is applied; (3), weed and pest control: after the planting, a planting bed of the ridges is covered; once konjac seedlings are grown, a complex solution containing Penicillium glabrum is applied every month, after half a month of the applying the complex solution, Qingkulike, matrine, and azadirachtin are applied; (4), fertilization: after the konjac seed corms enter a swelling period, a high-potassium organic fertilizer is applied.
