Manufacturing method for field test plot setter and device

Abstract

The invention discloses a manufacturing method for a field test plot setter and a device. The manufacturing method comprises the following steps: manufacturing a sealing bearing in the middle of a vertical insertion rod, and manufacturing a tape measure box with an angle measuring function on the vertical insertion rod below the sealing bearing, manufacturing a common bearing connected with the vertical insertion rod in the tape measure box, connecting the sealing bearing with the common bearing in the tape measure box through a bearing rotary rod, winding the tape measure on the outer ring of the common bearing in the tape measure box, drawing a straight line with special length according to the requirements, setting required straight line with special angel and length by taking the straight line as reference to define plots of a rectangular plot or a square plot or a parallelogram plot. The manufacturing method solves a problem that a conventional test plot has strict angle requirements on terrain during testing and is difficult to test, has dual functions of angle measuring and length measuring, and the vertical insertion rod can be telescopic for being conveniently carried; moreover, the manufacturing method has the advantages of being quick to set plot, simple in structure and operation, low in cost, wide in application prospect and the like.

Description

technical field [0001] The patent of the present invention relates to a manufacturing method and device of a plot setting device for field experiments, belonging to the technical field of experimental equipment. Background technique [0002] At present, field experiments refer to experiments in which crops are cultivated under field soil, natural climate and other environmental conditions, and various scientific researches related to crops are carried out. It plays an extremely important role in obtaining reliable scientific research conclusions to guide agricultural production through field experiments, comparison, identification, summary and improvement. When setting field test plots for different experiments, the plot area, shape, direction, arrangement, protection zone setting and repetition times all have specific requirements for angle and length. In the traditional field plot setting, the angle setting often adopts " Pythagorean theorem" (3m\7m\12m commonly used in t...

Problems solved by technology

When setting field test plots for different experiments, the plot area, shape, direction, arrangement, protection zone setting and repetition times all have specific requirements for angle and length. In the traditional field plot setting, the angle setting often adopts " Pythagorean theorem" (3m\7m\12m commonly used in the field is set to 900), such as the setting of square or rectangular plots, which have strict requirements on the terrain, which will cause time-consuming, inaccurate and difficult setting and other problems, the existing field test plot setting device has complex structure, cumbersome operation, time-consuming and laborious, so the existing field test plot setting device is still not perfect
