Description

Technical Field

[0001] The utility model belongs to the field of tobacco planting detection equipment, and specifically relates to a device for measuring the stem circumference of tobacco plants. Background Art

[0002] Tobacco is a plant of the genus Nicotiana in the Solanaceae family. It is an annual or limited perennial herb, covered with glandular hairs throughout; the root is sturdy. The stem is 0.7-2 meters high, and the base is slightly lignified. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, with a gradually pointed apex and a gradually narrowed base until the stem becomes ear-shaped and semi-amplexicaulous. The inflorescence is terminal, conical, and multi-flowered; the pedicel is 5-20 mm long. The capsule is ovate or oblong, about the same length as the persistent calyx. The seeds are round or broadly oblong, about 0.5 mm in diameter, and brown. It blooms and bears fruit in summer and autumn.

[0003] The stem girth of tobacco plants is one of the important agronomic traits of tobacco crops and a key indicator for monitoring tobacco growth and predicting economic traits. Usually, tobacco farmers or technicians use a soft rope or a soft ruler to measure the stem of the tobacco plant 5 to 6 leaves below the tobacco plant during the maturity period of tobacco leaves. However, since the stem girth of tobacco plants is small in size and most of the stems are irregular cylindrical aggregates, and the traditional method of measuring the stem girth of tobacco plants is to use a soft rope or a soft ruler, it is easy to cause large errors and low measurement efficiency.

[0004] The patent number CN202310359986.0 discloses a tobacco plant stem circumference measurement device and method, the device includes: an infrared measuring rod and a numerical control operator, the infrared measuring rod is connected to the numerical control operator, and is used to collect the measurement distance information of the target tobacco plant when receiving the measurement instruction, and send the measurement distance information to the numerical control operator: the numerical control operator is used to receive the measurement distance information sent by the infrared measuring rod, and determine the tobacco plant stem circumference of the target tobacco plant based on the measurement distance information. Based on the above technical scheme, the measurement distance information of the target tobacco plant is collected by the infrared measuring rod, and the measurement distance information is sent to the numerical control operator. After receiving the measurement distance information sent by the infrared measuring rod, the numerical control operator determines the tobacco plant stem circumference of the target tobacco plant based on the measurement distance information, thereby improving the accuracy of measuring the tobacco plant stem circumference and improving the measurement efficiency; this device can effectively increase the accuracy of tobacco plant stem circumference measurement, but this setting cannot be applied to all tobacco planting occasions.
