Description
Technical field
The invention belongs to agricultural mechanical fields, especially refer in particular to a kind of corn stem force tester resistant to lodging.
Background technology
Corn lodging is because wind and rain or mismanagement make plant inclination or the one kind to land during corn growth
Produce disaster.With the development of agricultural productive force and the rising of yield levels of maize, the contradiction of corn with high yield and lodging is increasingly
It is prominent, affect maize production.There are two types of factors for corn lodging：When kind, second is that weather, in the uncontrollable situation of the latter
Under, selection and breeding kind resistant to lodging becomes the most important thing of corn breeding work.
The tester of corn power resistant to lodging mainly applies the YYD-1B type Maize Stems of Zhejiang Top Instrument Co., Ltd. at present
Bar force tester resistant to lodging.The defects of above equipment, has, and 1, be not suitable for field test, it is necessary to transport plant felling
Be measured in laboratory, 2, test number it is inaccurate, be to apply plant placement level to cane during using above equipment
Plus-pressure makes it fracture so as to measure its compressive resistance index, and pressure is concentrated on some point of entire plant by this mode, with
The external force that natural wind forms plants stems bar applies that stressed form is different, and measured numerical value is inaccurate, and 3, due to needing
It is measured after felling, therefore measured plant can not continue to grow up, and what need to be measured is plant in full wafer experimental plot, therefore
It causes largely to waste, 4, a large amount of plant to be determined are cut down and transports to laboratory and sorts out selection, inherently makes workload
It is huge, 4, device fabrication need to have professional requirement, high expensive；The device that another kind measures corn endurance resistant to lodging is Shen
A kind of corn stem of the father's earlier application force tester resistant to lodging asked someone, which is to be arranged on pushing away on instrument by one
The defects of bar pushes over plant, the invention is, since plant is higher in itself, pushes over the distance of plant cane needs,
It can not complete to push over by an operating personnel and work with reading two parts, on the other hand, which is test
Corn stem maximum lodging endurance only by corn stem pushes over and reads the maximum power resistant to lodging that cane can bear completely,
And corn can not be calculated in the lodging tolerance born pushed over to different gradients, in another aspect, push rod connects with corn stem
Contacting surface product is small, and dynamics is more stiff, equally cannot preferably natural wind simulating power to the blow pressure process of corn stem, it is and easy
Cane is caused to damage, is unfavorable for tested corn stem and continues to grow up.In the understanding to the prior art, not yet find not damage
Hinder plant live body and the instrument for measuring power resistant to lodging can be completed.
Invention content
To overcome above-mentioned technological difficulties, the present invention provides a kind of cheap, simple structure, test corn easy to use
The device of cane lodging endurance.To realize above-mentioned technical functionality, the technical solution adopted by the present invention is that：
A kind of corn stem force tester resistant to lodging, described including riser, the side of the riser offers sliding slot, sliding slot
The trapezoidal slide block that can be moved up and down along sliding slot is embedded with, level meter is installed on the inclined-plane of the trapezoidal slide block, trapezoidal slide block
Tensiometer is installed, one end of the tensiometer is provided with noose, and the trapezoidal slide block is by being mounted on riser top on front end face
Spring connection, the riser lower part is equipped with universal joint, and the side of the riser bottom end is equipped with pedal, the bottom of the riser
Face is welded with locking-type plug, in use, tester is taken field, close to test plant；Stepping on pushes pedals with foot will
Whole device is fixed on the ground of corn stem；Noose is sleeved on corn stem or corn ear；By riser to one
Side is pushed over, and corn stem synchronizes bending lodging with device at this time, and trapezoidal slide block, which synchronizes, to glide, and makes drawing of the tensiometer to corn stem
Power in level, stops drag when level meter angle is designated as level always, and tensiometer shows that numerical value is that corn resists at this time
Lodge power.And at this time if corn stem does not fracture, noose can be unlocked by corn continued growth, live body will not be caused to damage
Wound.
Compared with above equipment, there are four this works major advantages, when the not damaged living body measurement in field, second is that time saving province
Work is laborsaving, can be completed by an operating personnel and pushes over corn stem and read two work of pulling force count value, third, using drawing
The mode of power makes the flexuosity that corn stem is presented when such as being blown to by wind-force, corn stem when more meeting natural wind blow pressure
Stress, therefore surveyed numerical value is more accurate, fourth, can test and read corn stem institute's energy under differently curved degree
The external force born can select different maize seeds by the wind condition of planting area during plantation, realize rationally should for maize seed resource
With.
Fig. 1 is schematic structural view of the invention.
Fig. 2 is side view of the present invention.
Specific embodiment
As shown in Figure 1, Figure 2, a kind of corn stem force tester resistant to lodging, including riser 1, the side of the riser 1
Offer sliding slot 2, sliding slot 2, which is embedded with, to be installed on the inclined-plane of the trapezoidal slide block 3 along the trapezoidal slide block 3 that sliding slot moves up and down
There is level meter 4, tensiometer 5 is installed, one end of the tensiometer 5 is provided with noose 6, described on the front end face of trapezoidal slide block 3
Trapezoidal slide block 3 is connected by the spring 7 for being mounted on riser top, and 1 lower part of riser is equipped with universal joint 8, the riser bottom end
Side pedal 9 is installed, the bottom surface of the riser is welded with fixed plug 10.
