Embodiment Construction

[0050] Such as Figure 1-Figure 3 As shown, the rice plant type measuring instrument of the present invention includes a base 7, which is provided with a concave slideway 15, and the base 7 and the slideway 15 are arcs with a central angle slightly greater than 180 degrees, and the two arcs The centers of the circles coincide. In this embodiment, the slideway 15 is formed by fixing the first and second slide bar presser feet 5 and 6 on the base 7 . The bottom of a height scale 2 is fixedly combined with slide bar 16, and this slide bar 16 is embedded in the slideway 15, and this slide bar 16 is the circular arc slide bar with this slideway 15 equiradius, so just makes slide bar 16 can Smoothly move in the slideway 15, thereby correspondingly driving the height scale 2 to move correspondingly along the slideway 15, meanwhile, the slideway 15 is provided with an angle scale gauge (not shown) to measure the moving angle of the slide bar 16, the height The scale 2 is provided wi...

Abstract

The invention relates to a paddy plant type measuring instrument and a method for measuring paddy plant type parameters. The paddy plant type measuring instrument comprises an arc slide way, an altitude scale, a sliding seat, a stalk pointer and a leaf direction pointer. The arc slide way is arranged on a base, and the central angle of the arc slide way is slightly larger than 180 degrees. The bottom of the altitude scale is combined with a sliding bar which is embedded in the slide way, and the slide way is provided with an angle dial compass. The sliding seat is embedded in the altitude scale, the stalk pointer perpendicularly penetrates through the sliding seat and the altitude scale and can move front and back and move up and down relative to the altitude scale, and the stalk pointer always points to the central axis of the base. One end of the leaf direction pointer is connected to one end of the stalk pointer through a first connection joint, the leaf direction pointer can rotate around the first connection joint in a plane parallel to the base, and the first connection joint is provided with a leaf direction angle scale. The other end of the leaf direction pointer is connected with a leaf curve pointer through a second connection joint, the leaf curve pointer can rotate around the second connection joint in the plane perpendicular to the base, the leaf curve pointer is provided with a dial compass, and the second connection joint is provided with a leaf curve angle scale.

Description

technical field [0001] The invention relates to a rice plant type measurement technology, in particular to a rice characteristic parameter measuring instrument and a rice plant type three-dimensional analog data measuring instrument. Background technique [0002] Rice plant type refers to the morphological characteristics, spatial arrangement and the relationship between various traits of rice, such as rice height, tiller distribution, leaf length, width and angle, ear shape, individual arrangement in the population and its geometric structure . [0003] The improvement of rice plant structure plays an important role in increasing the yield per unit area. Judging from the two breakthroughs in my country's rice production, one of the important reasons why the yield of dwarf varieties is higher than that of taller varieties, and that of hybrid rice than that of dwarf varieties, is the improvement of plant type. The first stage of plant type improvement is dwarf breeding, and...
