Description
Technical field
The device used in terms of the utility model is related to agri-scientific research, more particularly to a kind of survey resistant to lodging of corn inbred line
Determine instrument.
Background technology
Corn lodging is from erectility to the phenomenon of folding by extraneous factor initiation.Lodging is always to influence corn production
An important factor for amount and quality.Now with the horizontal continuous improvement of China's maize culture, the contradiction of dense planting and lodging is increasingly prominent
Go out, and because many uncertain natural causes occur, the trend for causing corn lodging to cause production loss in aggravation property.According to system
Meter, the general underproduction 20%~30% of corn lodging, severe patient are even had no harvest sometimes up to more than 50%.Therefore, seed selection is resistant to lodging
Corn variety is the economic and effective measures for preventing the lodging underproduction.And it is then that seed selection is anti-fall to identify corn inbred line lodging resistance
Lie prostrate premise and the basis of kind.
Utility model content
The utility model provides a kind of corn inbred line tools for measurement resistant to lodging, simple in construction, easy to use, during saving
Between, efficiency high.
A kind of corn inbred line tools for measurement resistant to lodging, including plant the soil surface for having plant for being placed on
Pedal, the center of the upper surface of described pedal is provided with the steamboat that can freely rotate, around described steamboat
It is provided with a drawstring, one end of described drawstring is connected to plant, the other end is connected with dynamometer.
Preferably, the upper surface of described pedal is rectangular and center is provided with a pair of bearings, described steamboat
It is arranged on by rotating shaft on the bearing described in a pair.
Preferably, the upper surface of described pedal offers non-slip groove.
Corn inbred line tools for measurement resistant to lodging of the present utility model, lodging resistant force, total can be measured by dynamometer
Simply, cost is low, is easy to carry, easy to use, time saving and energy saving, efficiency high.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the application schematic diagram for the corn inbred line tools for measurement resistant to lodging that the utility model embodiment provides.
Description of reference numerals：
1- pedals, 2- steamboats, 3- drawstrings, 4- dynamometers, 5- bearings, 6- non-slip grooves.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, a kind of corn inbred line tools for measurement resistant to lodging, including have plant for being placed on plantation
The pedal on soil surface, the center of the upper surface of described pedal are provided with the steamboat that can freely rotate, bypassed
Described steamboat is provided with a drawstring, and one end of described drawstring is connected to plant, the other end is connected with dynamometry
Meter, the upper surface of described pedal is rectangular and center is provided with a pair of bearings, and described steamboat is installed by rotating shaft
On the bearing described in a pair, the upper surface of described pedal offers non-slip groove.
Above-mentioned drawstring uses nylon cotton rope, is laid flat pedal during measure, one end close to plant (tested plant),
Stalk is tied with leather strap from the height of earth's surface 1/5th in plant (tested plant), then connects drawstring (nylon wire
Rope), drawstring (nylon cotton rope) is bypassed below steamboat, and drawstring (nylon cotton rope) is connected on dynamometer；Pedal is slammed with pin
Non-slip groove at, using steamboat as fulcrum, (protractor is used when plant (tested plant) is led down with ground in angle of 45 degrees
Survey), lodging resistant force kilogram number is read by dynamometer, measure is completed, packs up instrument.
The tools for measurement can measure lodging resistant force by dynamometer, and total is simple, and cost is low, be easy to carry, user
Just, it is time saving and energy saving, efficiency high.
Obviously, those skilled in the art can carry out various changes and modification without departing from this practicality to the utility model
New spirit and scope.So, if these modifications and variations of the present utility model belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to comprising including these changes and modification.
