[0020] Method of operation: before measuring the stem-leaf angle, straighten the tobacco stem and make it perpendicular to the ground. Place the ruler parallel to the straight line between the two points of the leaf base and the leaf position. Deflect the pointer, and after the pointer is stable, read the angle number pointed by the pointer on the protractor, which is the stem-leaf angle number.

[0021] When measuring the leaf length and width, place the ruler lightly above the tobacco leaf and press the tobacco leaf flat. When measuring the length, measure the distance from the leaf base to the leaf tip; when measuring the width, measure at the widest part of the tobacco leaf.

[0022] When measuring the plant height, straighten the tobacco stem, place the end of the ruler against the ground, and pull the tape up along the tobacco stem until the growth point. The plant height is the distance between the base of the tobacco stem and the growth point. BRIEF DESCRIPTION OF DRAWINGS
