Description

Technical Field

[0001] The utility model belongs to the technical field of measuring tools, in particular to a tiller bud height measuring ruler. Background Art

[0002] Sugarcane belongs to the genus Saccharum of the Poaceae family in terms of phylogeny. It is mainly planted in tropical and subtropical regions and is a perennial cash crop. Sugarcane is rich in sugar, with a sucrose content of 11.68-16.50%. It also contains a variety of vitamins, proteins, fats, calcium, iron and other nutrients that are beneficial to the human body. Its juice is the main source of sugar and molasses, and sucrose accounts for about 70% of the world's total sugar consumption. At the same time, sucrose and by-products can also be used in the production of alcohol fuel, so sugarcane is also a bioenergy crop. Sugarcane is a perennial asexually propagated crop, which mainly reproduces through the buds on its nodes. The buds germinate and develop into the main stem, and the lateral buds on the very short nodes at the base of the main stem germinate and develop into tillers. The main stem and tiller stems together constitute the harvesting organ of the sugarcane variety, the sugarcane stem, so tillering is one of the main factors affecting sugarcane yield.

[0003] In the process of breeding new sugarcane varieties, the measurement of tillering traits is also an indispensable task. Through the determination of tillering traits, we can understand the tillering characteristics of different new sugarcane varieties and provide experimental basis for breeding high-quality and high-yield sugarcane varieties. At present, there is no special ruler device for measuring the height of sugarcane tiller buds. Most of them are measured with tape measures and rulers. For the tiller buds that have just sprouted out of the ground, there are problems such as large errors and inconvenience in measurement.

[0004] The patent document with publication number CN105300253A discloses a rice tillering angle measuring instrument. The rice tillering angle measuring instrument includes a horizontal movable ruler and a vertical ruler, and the horizontal movable ruler and the vertical ruler are both provided with length scales; the horizontal movable ruler and the vertical ruler are arranged to intersect vertically, and the horizontal movable ruler can move along the vertical ruler; the horizontal movable ruler and the vertical ruler are both provided with a level. In the rice tillering angle measuring instrument of the invention, the levels on the vertical ruler and the horizontal movable ruler can ensure that the horizontal movable ruler is horizontal and the vertical ruler is vertical. The horizontal movable ruler is fixed to an appropriate height H of the vertical ruler according to the height of the rice tillering, and the width F of the rice tiller reaching the horizontal movable ruler is recorded. The rice tillering angle is automatically calculated in the Excel table by the inverse tangent function formula DEGREES (ATAN (F / H)). In height measurement, the horizontal movable ruler 1 needs to be fixed to an appropriate height of the vertical ruler 2 according to the height of the rice tiller to be measured, but the handheld movement process may affect the measurement accuracy.
