Problems solved by technology

For example, Li Shaokun, a maize expert at the Institute of Crop Science, Chinese Academy of Agricultural -2 ) and its impact on yield components”, there are 12 density treatments, and it is generally necessary to make 12 such density ropes of different specifications when sowing. The accuracy of the density cannot be guaranteed, and the daily management of these density ropes is also relatively cumbersome. It often happens that the rope labels are lost or the density ropes of various specifications are entangled.

Embodiment 1

[0015] Embodiment 1: Folding multi-standard corn field density ruler.

[0016] When conducting research on corn density, the commonly designed sowing densities include: 1,000 plants / mu, 2,000 plants / mu, 3,000 plants / mu, 4,000 plants / mu, 5,000 plants / mu, 6,000 plants / mu Mu, 7,000 plants / mu, 8,000 plants / mu, 9,000 plants / mu, 10,000 plants / mu, a total of 10 densities. The average sowing row spacing of general corn is 60cm, and the plant spacing is converted according to the corresponding density and the 60cm row spacing. The plant spacing of the above-mentioned different specifications of sowing densities are 111.2cm, 55.6cm, 37.1cm, 27.8cm, 22.2cm, 18.5cm, 15.9cm cm, 13.9cm, 12.4cm, 11.1cm.

[0017] The stainless steel short ruler (1) is ferritic stainless steel, which can be adsorbed together with the magnetic nail (2); the total length of the folding stainless steel ruler is 5.6m, and it is composed of 8 short rulers, each of which is 70cm long and 3cm wide; Each section of ...

Embodiment 2

[0019] Embodiment 2: Folding multi-standard soybean test field density ruler.

[0020]When conducting research on soybean density, the sowing densities that may be designed for the experiment include 3,000 plants / mu, 6,000 plants / mu, 9,000 plants / mu, 12,000 plants / mu, 15,000 plants / mu, and 18,000 plants / mu. There are 6 densities in total. Generally, the average sowing row spacing of soybeans is 50cm, and the plant spacing is converted according to the corresponding density and the 50cm row spacing. The plant spacing of the above-mentioned different specifications of sowing densities are 44.5cm, 22.2cm, 14.8cm, 11.1cm, 8.9cm, 7.4cm, so On the front and back of the short stainless steel ruler (1), respectively divide into 3 rows and mark corresponding density data (3) according to the distance between plants: 3,000, 6,000, 9,000, 12,000, 15,000, 18,000. Finally, mark the density unit as "plant / mu" and the row spacing as "50cm" in the upper right corner of the folding density ru...

Abstract

The invention discloses a collapsible type multi-specification crop experimental field density ruler, for the purposes of facilitating carrying management, realizing multiple purposes in one ruler and realizing accurate density. The collapsible type multi-specification crop experimental field density ruler comprises a collapsible type stainless steel ruler and magnetic nails; the collapsible type stainless steel ruler comprises multiple short ruler sections, each short ruler is made of a ferrite or martensite stainless steel material, a first short ruler section and a last short ruler section are each provided with a rivet at one end, and other short ruler sections are each provided with rivets at two ends; two adjacent short ruler sections are connected through the rivets; the magnetic nails are composed of circular plastic shells and magnets embedded therein, and the plastic shells are bright in color and are circular-shaped; different sawing densities frequently designed in a test are marked on the front surface and the back surface of each short ruler according to rows, same-density data in the same raw are distributed at equal intervals, and the intervals are the plant spacings of the marked densities; the row spacings of all different densities of the same density ruler are unified and the unified row spacing is an average sawing row spacing of a certain crop; the row spacings and a density unit are marked at the right upper corner of the collapsible type density ruler; and the magnetic nails are absorbed on the data of the employed densities at equal intervals.

Description

technical field [0001] The invention discloses a foldable multi-standard crop test field density ruler, which relates to the field of agricultural scientific research and is used in sowing experiments in plots, and is especially used in the sowing link of density tests. Background technique [0002] In crop cultivation research, density is a key cultivation factor, so density research is essential, that is, through various specifications of density experiments, to seek a reasonable planting density of crops, and ultimately achieve the goal of high yield and high efficiency. In recent years, with the replacement of crop varieties and the enhancement of resistance, the density tolerance of crop varieties has gradually increased, and more and more researches have been done on density. When planting plots according to the density set by the test, a certain row spacing is usually achieved by a row marker, for example: "A kind of adjustable crop test field marker" disclosed in Chi...
