Description

Corn plant high stem and coarse leaf included angle measuring scale

Technical Field

The utility model belongs to the technical field of the agricultural is grown seedlings, concretely relates to maize plant height stem thick leaf contained angle dipperstick.

Background

In the corn variety identification test and breeding process, the measurement and survey of the ear height, the plant height, the stem thickness and the leaf included angle of the corn are important contents for tracking the characteristic characteristics of the corn variety and evaluating the adaptability of the corn variety in the breeding process, and are also important characteristics related to the variety popularization and the matching of the cultivation technology.

At present to the measurement of characters such as maize ear of grain position height, plant height, it is artifical with the tape measure respectively usually, measuring stick or bevel protractor measure, because maize plant height is higher relatively, planting density is great, it measures to go into maize interline deeply in summer, high temperature and high humidity, measuring space is little, working strength is big, measurement accuracy is low, especially later stage plant height can be up to 2 meters more, need look straight up when the ruler is measured, therefore measure very difficultly, and multiple data measurement need use different kind of instrument, the field operation carries a large amount of instruments very inconveniently.

In the figure: 1. slide caliper rule, 2, extension rod, 3, shrink tape measure, 4, fixed ruler, 5, laser range finder, 6, cable, 7, angle pole, 8, shrink pole, 9, scale mark, 10, horizontal bubble, 11, base.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 and 2, the present invention provides a technical solution: a corn plant high stem and thick leaf included angle measuring ruler comprises a fixed ruler 4 and an extension rod 2; the fixed ruler 4 is provided with scale marks, the total length is 1.5m, the thickness is 3cm, two sides of the bottom of the fixed ruler 4 are provided with bases 11, the bases 11 are provided with horizontal bubbles 10, and the bases 11 are also provided with laser range finders 5; extension rod 2 from the top inserts inside fixed ruler 4, 2 bottoms of extension rod are equipped with the bayonet socket pearl, can highly stop wantonly in fixed ruler 4, 2 tops of extension rod are equipped with slide caliper rule 1, 2 inside shrink tape measure 3 that still are equipped with of extension rod, 2 inside spaces that are equipped with of extension rod are accommodated and are put shrink rod 8.

Specifically, the telescopic rod 8 is connected with the inhaul cable 6, and the top of the telescopic rod 8 is provided with a bayonet bead, so that the telescopic rod 8 can play a role in fixing when being retracted into the extension rod 2.

In particular, the cable 6 is connected to an angle lever 7.

In particular, the line of the angle bar 70 ° coincides with the line of the retraction rod 8 after being pulled out, the angle bars 730 ° and 60 ° being thicker than the angle bars 715 °, 45 ° and 75 °.

During the use, put base 11 near the volume of awaiting measuring maize, ensure that the top is bladeless and shelters from, observe whether horizontal bubble 10 is horizontal, the mode adjustment to the level of the unhooked use bed soil, hold slide caliper rule 1 with exerting oneself slightly, pull out extension rod 2 from solid fixed ruler 4, put slide caliper rule 1 in maize trunk top and carry out the plant height and measure, open laser range finder 5, the laser point is penetrated in slide caliper rule 1 bottom, record the trunk height after the measurement, the height of ear position is measured and the record to the same reason, press down the telescopic power slightly and receive back to suitable height, pull out shrink tape measure 3 from extension rod 2, carry out the rough stem around the maize stem and measure and record. The base 11 is moved to a proper position for leveling and then the leaf included angle is measured, the contraction rod 8 is pulled out from the telescopic tape measure, the angle rod 7 is automatically released to the angle position due to the pulling force of the inhaul cable 6, the leaf angle is measured and recorded after the base part of the contraction rod 8 is aligned with the leaf base part, after the use, the contraction tape measure 3 is automatically retracted into the contraction tape measure 3, the contraction rod 8 is lifted, the contraction rod 8 is clamped back to the extension rod 2, the caliper 1 is slightly pressed downwards with force, and the caliper 1 is in contact with the fixed ruler 4.
