Description

Teaching investigation instrument of plant breeding

Technical Field

The utility model relates to a teaching and surveying tool for plant breeding, which is used for plant breeding index survey records and belongs to the field of plant breeding teaching and scientific research.

Background

The teaching and scientific research practice of plant breeding courses needs to guide students to conduct field investigation on indexes such as plant and fruit characters, pest and disease damage conditions and the like of breeding objects, and in the process, general students use paper color map tools to conduct comparison and recording. When a plurality of investigation items are available, the paper atlas is inconvenient to use and other operations are carried out at the same time, the investigation can be completed only by matching two or more persons, the speed is low, the learning efficiency is low, and a large amount of time and labor are consumed; in breeding survey, only one or more plants are usually faced, and the paper map is used for repeated browsing and repeated operation, so that the pertinence is not strong, and the time and the energy are wasted; the paper color atlas is high in price, so that a uniform album cannot be generated, and the teaching quality is influenced; the paper map is heavy, is inconvenient to carry and read in the field, and is easy to damage and dirty. Therefore, there is a need for a portable survey tool that is simple to operate, suitable for field use, and capable of rapidly and efficiently comparing and determining various trait indexes of plant breeding objects.

Disclosure of Invention

The utility model aims to provide a teaching investigation tool which is simple to operate, is suitable for field use, can rapidly compare and determine various character indexes of plant breeding objects, improves the learning efficiency of student practice, ensures the teaching quality and is convenient to use.

The purpose of the utility model is realized by the following technical scheme: the utility model comprises a cuboid rotary drum and a recording plate, and is characterized in that: the side that is equipped with a plurality of rectangle photo draw-in grooves has cuboid rotary drum of scale and is equipped with a whole that the record board of supporting pivot combines.

The rotary drum is a cuboid, is 15-20cm long, 8-10cm wide and high, is 2-3mm thick and is made of plastics.

On the rotary drum, 8-12 rectangular clamping grooves are arranged on the four outer surfaces and are arranged in two rows, and the clamping grooves are 6-8cm long and 1-2cm wide.

On the rotary drum, four long sides of the outer surface are provided with scales for marking the length of 100 mm.

Four cylinder arms are respectively arranged inside two ends of the rotary cylinder, round holes are formed in the center joints of the four cylinder arms, and the cylinder arms are equal to 1.414 times of the width of the rotary cylinder.

The color photos are rectangular, the size of the color photos is matched with the clamping groove in the sleeve, the content of the color photos is standard photos of various plant breeding character indexes, and the photos are provided with corresponding names.

The recording plate is rectangular, 25-30cm long, 15-20cm wide and 2-3mm thick, is made of plastic, and is provided with a rotating shaft at the front part, and the rotating shaft is matched with a round hole on a drum arm of the rotating drum. The width of the rotating shaft is equal to that of the recording plate, the width of the shaft arm is equal to that of the rotating drum which is 1.414 times, and the shaft arm and the recording plate form an included angle of 135 degrees.

The utility model has the advantages that: the method has the advantages that the economy is high, the production cost is low, various index types of plant breeding objects can be rapidly determined in a comparative manner, a paper map tool is effectively replaced, color photos can be repeatedly utilized, the operation is carried out by one person, and material resources and manpower are saved; the utilization efficiency is high, other practical operations can be simultaneously carried out by using the utility model, and the time is saved; the method has wide application range, can be used for carrying out breeding character index investigation aiming at various plants, and can also be used for carrying out general measurement on various plants by utilizing the scales marked on the method; the operation is simple, and the utility model can be rotated by hands for use; the portable electric water heater is convenient to carry, is made of plastic, has small volume and light weight, and is suitable for being used in fields; the utility model has the advantages of environmental protection, durability, no pollution, simple structure and difficult damage.

Detailed Description

Referring to the attached drawings, rectangular standard color photos 3 with different plant breeding characters are tightly inserted into clamping grooves 2 matched on a rotary drum 1, and the photos are displayed in different peel colors, fruit flesh colors, fruit shapes, leaf shapes, diseases, insect pests and the like of a certain plant.

In the specific operation, the recording plate 4 is stabilized, the tool is pointed to an investigation object, the rotary drum is rotated aiming at a certain plant breeding investigation target, the drum arm 5 is overlapped with the shaft arm 7 on the rotary shaft 6 of the recording plate, the surface of the rotary drum to be used for character comparison reference is found, the type or grade of specific investigation characters is determined according to the photos, and meanwhile, paper can be laid on the recording plate for relevant recording.

The four long edges of the outer surface of the rotary drum are all marked with scales 8 which are accurate to millimeter and mark the length, and the rotary drum can be used for related plant measurement work.
