Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stropharia rugosoannulata cultivation is hindered by excessive moisture leading to waterlogging, mycelial mildew, and impaired growth, particularly at the bottom of the cultivation substrate, resulting in reduced yield.
Innovation Solution
Implementing methods for moisture control through ridging, walkway arrangement, substrate surface elevation, and strategic hole formation in shelves or pots, combined with atomization spray irrigation and micro-mist humidification to maintain optimal humidity levels and facilitate drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If drainage holes are formed at the bottom of the cultivation substrate, then waterlogging is prevented, but the structural integrity of the substrate may be compromised
Solution Approach 1:
The cultivation substrate incorporates porous materials such as perlite, vermiculite, or expanded clay aggregates that create internal drainage channels and air pockets. These porous structures enable water to drain through the substrate matrix without requiring large holes that would compromise structural integrity, thus preventing waterlogging while maintaining substrate strength
Solution Approach 2:
Instead of creating vertical drainage holes through the substrate depth, the patent implements a lateral drainage dimension by forming channels along the bottom surface of the substrate or incorporating a drainage layer beneath the substrate. This dimensional approach allows water removal without penetrating the substrate structure vertically, preserving its integrity
2Productivity
If moisture content is increased to promote hyphae growth, then growth rate improves, but waterlogging and mycelial mildew occur
Solution Approach 1:
The patent optimizes the moisture content parameter to a specific range (60-70% field capacity) and maintains it through controlled irrigation and drainage systems. This parameter control ensures sufficient moisture for rapid hyphae growth while preventing excess water accumulation that would create anaerobic conditions favorable for mycelial mildew
Solution Approach 2:
The cultivation system incorporates moisture sensors and drainage control mechanisms that continuously monitor substrate moisture levels and automatically adjust water removal rates. This feedback control maintains moisture within the optimal range, promoting hyphae growth while preventing the waterlogging conditions that lead to mycelial mildew
3Object-affected harmful factors
If the bottom surface of the cultivation substrate is elevated, then drainage is improved, but the stability of the substrate structure may be reduced
Solution Approach 1:
The substrate is prepared with pre-formed drainage channels and an elevated bottom surface structure before cultivation begins. This preliminary structural arrangement ensures drainage capability is built into the substrate matrix itself, allowing water to flow away from the bottom surface without requiring additional support structures that would compromise stability
4Speed
If drainage holes are made larger or more numerous, then water removal efficiency increases, but the substrate becomes more vulnerable to structural damage
Solution Approach 1:
The substrate incorporates distributed porous materials that create numerous small-scale drainage pathways throughout the substrate matrix. This approach provides high water removal efficiency through the combined effect of many small channels while maintaining structural integrity, as the porous materials are integrated into the substrate without creating large vulnerable holes

AI summary
The present invention belongs to the technical field of large-scale fungus cultivation, and specifically relates to a water control method in a cultivation process for Stropharia rugosoannulata. In the water control method in the cultivation process for Stropharia rugosoannulata provided by the present invention, a cultivation method comprises field planting, shelf-type cultivation or potted cultivation. When the cultivation method is field planting, the bottom surface of a culture medium is higher than the lowest position of an aisle by greater than or equal to 1 cm, so that accumulated water at the bottom of the culture medium can be discharged. When the cultivation method is shelf-type cultivation or pot-ted cultivation, the number and diameter of bottom holes of the shelf or the pot are controlled such that the water-dripping time after a single watering is less than or equal to 3h, and accumulated water in the culture medium can be effectively prevented. The cultivation process of the present invention also comprises a step of stimulating fruiting of the Stropharia rugosoannulata, so that nutrients in the culture medium are fully used, a fruiting period is prolonged, and yield is increased.
