Solution Overview
Problem
Existing Morchella cultivation methods face issues of unstable yield, low fruiting rate, and high production costs, failing to meet market demand and resulting in poor quality and seasonal limitations.
Innovation Solution
A cultivation method for Morchella on patterned layer frames, utilizing specific temperature controls (5-9°C for exogenous nutrition transformation and 2-4°C for primordium induction) with a unique culture substrate composition (mountain raw soil, grass carbon, caustic lime, gypsum, and potassium dihydrogen phosphate) and precise environmental conditions (carbon dioxide, humidity, and light cycles) to stabilize yield and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional cultivation methods are used, then the cultivation process is simple, but the yield is unstable and fruiting rate is low
Solution Approach 1:
The cultivation process is divided into distinct stages with specific temperature requirements: exogenous nutrition transformation (5-9°C), mycelium culture (5-9°C), primordium induction (2-4°C), and primordium differentiation (5-9°C). This segmentation allows precise control over each growth phase, stabilizing yield and improving fruiting rate.
Solution Approach 2:
The patent implements dynamic temperature parameter changes throughout the cultivation cycle. Temperature is adjusted according to specific growth stages: maintained at 5-9°C during nutrition transformation and mycelium culture, lowered to 2-4°C for primordium induction, then raised to 5-9°C for differentiation. This parameter optimization resolves the contradiction between simple processes and stable high yield.
2Productivity
If traditional cultivation methods are used, then production costs are high, but the fruiting rate is low and quality is poor
Solution Approach 1:
By optimizing temperature parameters for each growth stage and using a standardized substrate formula (mountain raw soil 34-55%, grass carbon 40-60%, caustic lime 1-3%, gypsum 2-4%, potassium dihydrogen phosphate 0.05-0.2%), the patent achieves high fruiting rates while controlling costs through efficient resource utilization.
Solution Approach 2:
The patent uses strain blocks (1-1.5 cm size, 0.4-0.6 kg/m²) as standardized inoculum units that can be replicated and distributed uniformly across the culture substrate, ensuring consistent fruiting results and quality while reducing per-unit production costs.
3Productivity
If traditional cultivation methods are used, then seasonal limitations exist, but facility cultivation with temperature control enables continuous supply
Solution Approach 1:
The patent implements periodic temperature adjustments corresponding to different growth stages: 5-9°C for nutrition transformation and mycelium culture, 2-4°C for primordium induction, and 5-9°C for differentiation. This periodic temperature regimen enables continuous facility cultivation year-round, overcoming seasonal limitations while managing energy consumption efficiently.
4Manufacturing precision
If low temperature (2-4°C) is used for primordium induction, then primordium differentiation is improved, but the temperature control requirement increases
Solution Approach 1:
The cultivation process segments temperature control into distinct phases: a brief low-temperature period (2-4°C) specifically for primordium induction, surrounded by moderate temperature periods (5-9°C) for other stages. This segmentation achieves high primordium differentiation quality while limiting the duration and complexity of low-temperature control requirements.

AI summary
A cultivation method for Morchella on patterned layer frames is provided. The method includes: (1) preparing and laying a culture substrate, and sowing; (2) supplementing an exogenous nutrient material; (3) mycelium culture; (4) primordium induction; (5) primordium differentiation; (6) management of a young mushroom period; (7) maturity management; and (8) erchao mushroom management. The method adopts a low temperature of (5-9° C.) to promote a transformation of an exogenous nutrition and adopts a low temperature of (2-4° C.) to induce a differentiation of primordium and other measures, to address a bottleneck of industrial development that cannot continuously supply fresh Morchella to the market, which is caused by some problems in the cultivation of Morchella, such as an unstable yield and seasonal limitation in the existing cultivation of Morchella. The method can carry out industrial facility cultivation for Morchella, and can obtain Morchella with stable yield and good quality.
