Abstract

The invention provides a calibration method and a calibration device for the moisture content of fallen leaves. The method comprises the following steps: measuring the weight W1 of a special box; putting the leaves into the special box; measuring the weight W2 of the special box with the leaves; taking out all the leaves from the special box, and heating the leaves; cooling the heated leaves, and removing condensed water; re-putting the treated leaves into the special box; measuring the weight W3 of the special box with the treated leaves; measuring the moisture content H2 in the special box through a humidity sensor; calculating a real moisture content Q of the fallen leaves, and recording the real moisture content Q of the fallen leaves and the corresponding moisture content measured value H2 as a group of data; repeatedly carrying out the steps for multiple times to obtain multiple groups of data, and analyzing to obtain a quantitative relation f between the real moisture content Q of the fallen leaves and the moisture content measured value H2; under a condition of the measured moisture content, obtaining a corresponding real moisture content of the fallen leaves according to the quantitative relation f. According to the calibration method, the measurement process of the moisture content of the fallen leaves is effectively simplified, and the measurement precision and the measurement efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of forestry science and technology, in particular to a method for calibrating moisture content of fallen leaves suitable for a tubular FDR sensor and a supporting tool thereof. Background technique [0002] The water content of the forest deciduous layer is directly related to the possibility of forest fires, and the measurement of the moisture content of the forest deciduous layer can provide a reference for forest fire early warning. At present, the tubular FDR sensors sold on the market are mainly used in the measurement of soil moisture. Due to the wide variety of fallen leaves, the leaves are full of gaps. If the tubular FDR sensor is used to measure the moisture content of fallen leaves, a relatively complete calibration tool and method are required. . However, there is no calibration method for tubular FDR sensors in the application of leaf moisture content measurement at this stage. Contents of th...
