Abstract
The invention discloses a corn stem lodging resistant force tester, and belongs to the mechanical field. The tester comprises two vertical plates (1,2), a chute (3) is arranged in the middle of a plane arranged between two vertical plates (1,2); a sleeve (4), which can move along the chute (3) up and down, is arranged in the chute (3); a push rod (5) is arranged in the middle of the sleeve (4); a push/pull force meter (6) is arranged between the vertical plate (2) and the push rod (5); the upper parts of the vertical plates (1,2) are connected by a sealing plate (7), the lower parts of the vertical plates (1,2) are connected by a sealing plate (8); the lower part of the upper sealing plate (7) is provided with a spring (9), the sleeve (4) is connected to the bottom end of the spring (9); a reeling wheel (10) is arranged on the lower sealing plate (8), and the pulling rope (11) of the reeling wheel is connected to the sleeve (4). The operation of the tester is simple, the structure of the tester is light, and the tester can be used to test the lodging resistant force of individual strains in the same test field so as to selectively breed excellent species.
Description
Technical field
The invention belongs to mechanical field, 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 miscarriage make milpa tilt or a kind of production disaster of landing in corn growth process.Along 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 more and more outstanding, affects Maize Production.Corn lodging has two kinds of factors: one is kind, and two is weather, and in the uncontrollable situation of the latter, seed selection kind resistant to lodging becomes the most important thing of corn breeding work.
Corn lodging mainly causes by disaster caused by a windstorm.Therefore when corn breeding, the holding capacity of corn stem lodging just becomes an important indicator, because this directly concerns the wind-force that corn can be resisted when growing up.To the grasp of corn stem lodging holding capacity, can filter out comparatively outstanding kind, the difference according to kind can select different planting bases, improves survival rate and the output of corn.The test corn stem lodging holding capacity wanting energy relatively accurate, crucial difficult point is when applying external force to corn stem having two: one, ensure that the external force of corn stem is born a little to move down with the lodging course synchronization of corn stem, the external wind-force that so could bear during corn stem lodging when dummy level wind-force is applied on corn stem to greatest extent; Two is can realize carrying out plant division test to corn a slice corn trials Tanaka, can not only test the corn of periphery.Also to consider except above-mentioned factor the measuring equipment that makes can not cost too high, operation should be very easy, simultaneously not by the interference of other foeign elements such as corn stem leaf blocks.But in current all technology, not independent equipment that corn lodging holding capacity is calculated or instrument.
Summary of the invention
For overcoming above-mentioned technological difficulties, the invention provides the device of a kind of cheap, simple structure, test corn stem easy to use lodging holding capacity.For realizing above-mentioned technical functionality, the technical scheme that the present invention takes is:
A kind of device testing corn stem lodging holding capacity, comprise two pieces of risers, chute is offered in the middle of the plane of two pieces of risers, in chute, a sleeve pipe that can move up and down along chute is installed, arrange one in the middle of sleeve pipe and push away stalk, riser and push away between stalk and be provided with pull and push dynamometer, the upper and lower of two pieces of risers connects by two pieces of seal pads, below superposed seal pad, a spring is installed, sleeve pipe is connected to spring bottom end, be provided with take-up reel on the seal pad being positioned at bottom, the drag-line of take-up reel is connected on sleeve pipe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is side view of the present invention.
Embodiment:
Composition graphs 1, shown in Fig. 2, a kind of device testing corn stem lodging holding capacity, comprise two pieces of risers 1, 2, two pieces of risers 1, chute 3 is offered in the middle of the plane of 2, in chute 3, a sleeve pipe 4 that can move up and down along chute 3 is installed, arrange one in the middle of sleeve pipe 4 and push away stalk 5, riser 2 and push away between stalk 5 and be provided with pull and push dynamometer 6, two pieces of risers 1, the upper and lower of 2 is by two pieces of sealings 7, 8 plates connect, below superposed seal pad 7, a spring 9 is installed, sleeve pipe 4 is connected to spring 9 bottom, the seal pad 8 being positioned at bottom is provided with take-up reel 10, the drag-line 11 of take-up reel 10 is connected on sleeve pipe 4.
During use, take-up reel is utilized to be pulled by the sleeve pipe being suspended on lower spring end at the uniform velocity downwards, the stalk that pushes away simultaneously manually promoted in the middle of sleeve pipe by workman applies horizontal thrust to corn stem, riser and the pull and push dynamometer pushed away between stalk are pulled and start metering, until corn stem is pushed over completely or thrust maximum under the postscript that fractures, thus the cultivation selecting the stronger corn seed of holding capacity purposeful.
This device has the following advantages:
1, equipment cost is cheap, simple structure, easy to use.The necessary handled easily of such set of device is just taken into full account before conceiving this device, with low cost.Because equipment complexity can raise the cost undoubtedly, operation easier the excessive workman to farm work also can have higher requirements.
2, this device can be tested each strain corn in experimental plot, because corn planting compares comparatively dense, to being planted in all will testing respectively with the corn of centre of periphery, experimental plot, this device can realize this technical requirement, can be tested each strain corn by the movement of position.
3, the external force of corn stem bear a little with the lodging process horizontal synchronization of corn stem, stress when blowing to corn stem closest to wind-force level.
Claims (1)
1. a corn stem force tester resistant to lodging, it is characterized in that: comprise two pieces of risers (1, 2), two pieces of risers (1, 2) chute (3) is offered in the middle of plane, in chute (3), a sleeve pipe (4) that can move up and down along chute (3) is installed, in the middle of sleeve pipe (4), a push rod (5) is set, pull and push dynamometer (6) is installed between riser (2) and push rod (5), two pieces of risers (1, 2) upper and lower is by two pieces of seal pads (7, 8) connect, a spring (9) is installed in superposed seal pad (7) below, sleeve pipe (4) is connected to spring (9) bottom, the seal pad (8) being positioned at bottom is provided with take-up reel (10), the drag-line (11) of take-up reel (10) is connected on sleeve pipe (4).
