Problems solved by technology

This detection method is limited by the manual insertion of a gas sampling tube in the grain pile, which is generally only about 0.5 meters, and it is difficult to obtain information on insect and mold activity in the entire granary
The other is to bury gas pipelines at different depths and locations in the grain piles to detect carbon dioxide gas in the grain piles. However, the existing methods do not combine the diffusion characteristics of carbon dioxid

Embodiment 1

[0021] Example 1: Insect and mold activity positioning 1 (one positioning key point, two positioning related points)

[0022] Such as figure 1As shown, it is the floor plan of insect and mildew activity monitoring in a flat warehouse of 32 m×24 m×6 m (length×width×height). The distribution of monitoring points is as follows: the distance between the monitoring points near the warehouse wall and the wall is 4 m, and the distance between monitoring points is 8 m; the detection time interval is 7 days, and the obtained data are marked on the right side of each monitoring point in the figure. The upper data is the measured value of carbon dioxide concentration at the 3 m monitoring point (unit: %), and the lower data is the measured value of carbon dioxide concentration at the 6 m monitoring point (unit: %). Analyze the detected data, and compare the detection value of each monitoring point with the previous detection data. The monitoring points with a detection value greater tha...

Embodiment 2

[0024] Example 2: Insect and mold activity positioning 2 (one positioning key point, three positioning related points)

[0025] image 3 It is the floor plan of insect and mildew activity monitoring in a one-storey warehouse of 32 m×24 m×6 m (length×width×height). The distribution is as follows: the distance between the monitoring points near the warehouse wall is 4 m from the wall, and the distance between monitoring points is 8 m; the detection time interval is 7 days, and the obtained data are marked on the right side of each monitoring point in the figure, and the upper data is the measured value of carbon dioxide concentration at the 3 m monitoring point (unit: %), and the data below is the measured value of carbon dioxide concentration at the 6 m monitoring point (unit: %). Analyze the detected data, and compare the detection value of each monitoring point with the previous detection data. The monitoring points with a detection value greater than 1% are the lower layers...

Abstract

The invention discloses a method for positioning activities of Entomophthora in grain piles of grains stored in a grain bin. According to characteristics of grain piles, monitoring layers are respectively selected and set in the vertical direction of the grain piles; carbon dioxide gas concentration monitoring points are arranged at certain interval on each monitoring layer; and through periodically detecting changes of the carbon dioxide gas concentration of each monitoring point and according to distribution of grain pile carbon dioxide gas concentration, key points and relative points of activities of Entomophthora in the grain piles are determined and activity spaces and parts of Entomophthora in the grain piles are positioned.

Description

technical field [0001] The invention belongs to the technical field of grain storage safety monitoring, and in particular relates to a method for measuring the concentration of carbon dioxide in a specific part of a grain pile in a granary, and according to the diffusion characteristics of carbon dioxide gas in the grain pile, to monitor the growing and metabolizing insects in the grain pile. Locate the active part of the fungus to provide a basis for accurate prevention and control of the hazards of the fungus in stored grains. Background technique [0002] The scale of my country's grain reserves is large and the storage time is long. During the storage period, it is unavoidable that insects and mold hazards will occur. The early stage of insect mold growth usually occurs in a certain area of ​​the grain pile, and then continues to expand to the surrounding area, eventually leading to serious loss of stored grain, such as causing deterioration of grain apparent quality, e...
