Abstract

The invention discloses a tobacco plant spread angle measuring instrument. The tobacco plant spread angle measuring instrument comprises a vertical fixed bar and a cross bar, wherein a collar is arranged at the left end of the cross bar; the cross bar is fixed on the vertical fixed bar through the collar, and is perpendicular to the vertical fixed bar; a screw on the collar can tightly top the vertical fixed bar to realize fixing of the cross bar; the cross bar is provided with scales; the top of a movable measuring rope sleeves the cross bar; and an iron awl is arranged at the bottom of the movable measuring rope. The tobacco plant spread angle measuring instrument provides a convenient and scientific measuring mode for the spread angle of tobacco plants, and has the advantages of being simple in structure, being convenient to produce, being easy to carry, being able to reuse, being accurate in measuring results, and being able to reduce the measurement error.

Description

technical field [0001] The invention relates to a tobacco plant spreading degree measuring instrument, which belongs to the technical field of agricultural measurement. Background technique [0002] Tobacco is a plant belonging to the genus Nicotiana in the family Solanaceae. In the process of scientific research, it is often necessary to measure its expansion, plant height and other indicators. Usually, a ruler or tape measure is used for measurement. However, in the later stage of tobacco plant growth, the tobacco plant is relatively large, and it is inconvenient to use a ruler or tape measure to measure, and it may damage the tobacco leaves. The cluster stage is an important growth period in the growth process of tobacco plants in the field, and its determination requires the data of the expansion degree and height of tobacco plants. Therefore, accurate measurement of the expansion degree not only provides reliable data for scientific research, but also provides a reliab...
