| description | The invention discloses a sample preparation method for detecting physical properties of tobacco leaves and application. The sample preparation method comprises the following steps: standing the tobacco leaves to be detected in an environment with the temperature of 49-51 DEG C and the relative humidity of 68-72% for 46-50 hours; the method comprises the following steps: obtaining a sample with the ratio of length to width of (6-8): (2-4) in the middle of a tobacco leaf to be detected along the lateral vein growth direction; the long edge of the sample is parallel to the extension direction of the side vein of the tobacco leaf; and S2, placing the sample obtained in the step S2 in a sample fixing device of a tearability instrument, cutting the sample into a notch with the length of 1-2cm, and measuring the force required for tearing the sample by using a detection device of the tearability instrument, namely the tear strength of the tobacco leaf to be detected. The method provided by the invention can be used |
