First, increase the temperature of the shed and promote the mushrooming of edible fungi. Pleurotus ostreatus appropriately increases the light and sprays a new high-fat film to increase photosynthesis and increase the temperature inside the shed; the double-spore mushroom shed is covered with a film, and a new high-fat film 800 times liquid is sprayed on the surface of the mushroom to protect the water-proof evaporation. Insulation and antifreeze ensure that the mushrooms can still be produced normally in winter.
Second, keep warm and cold, hydrating and controlling humidity. After the edible fungus grows in autumn, the bacteria stick loses more water and should be replenished in time. Mushrooms do not need to be hydrated in winter. Third, timely ventilation and ventilation, before and after the high temperature around noon. It should be accessed from the south side of the shed to prevent cold winds.

Roundness Measuring Instrument
A roundness meter is a measuring tool that uses the rotation axis method to measure the roundness error of a workpiece. The roundness tester is divided into two types: sensor rotary and workbench rotary. During measurement, the measured part is installed concentric with the precision shaft system, and the precision shaft is equipped with an inductive length sensor or workbench for precise circular motion. The roundness meter consists of an instrument's sensor, amplifier, filter, and output device. If the instrument is equipped with a computer, the computer is also included in this system.
A roundness meter is a precision instrument used to measure the out of roundness of a rotating surface (shaft, hole, or spherical surface) of a component. There are usually two types: small desktop, where the workpiece is mounted on a rotating workbench and the measuring head is mounted on a fixed column; Large floor mounted, with the workpiece installed on a fixed workbench and the measuring head installed on the rotating spindle. During measurement, the measuring head contacts the surface of the workpiece, and the rotating part of the instrument (workbench or spindle) rotates for one cycle. Due to the extremely high accuracy of the supporting bearings in the rotating part, the measuring head will generate a high-precision circular trajectory on the measured surface during rotation. The out of roundness of the measured surface causes the measuring head to shift and transform into an electrical (or pneumatic) signal. After amplification, it can be automatically recorded on a circular recording paper, and the out of roundness of each part can be directly read out for accuracy evaluation and process analysis. Widely used in precision bearings, machine tools, and instrument manufacturing industries.
The roundness meter adopts a radius measurement method and operates in a rotating manner. The rotation axis system of the roundness meter adopts a high-precision air floating spindle as the measurement reference; The electrical part of the roundness tester is composed of advanced computers, precision circular grating sensors, and precision inductance displacement sensors. The circular grating sensors and precision inductance displacement sensors measure angle and radial displacement, ensuring the accuracy of measuring the angular displacement and radial value of the workpiece; The roundness meter measurement software adopts a roundness measurement software based on the Chinese version of WinXP operating system platform, completing data collection, processing, and measurement data management.
