Abstract
The utility model discloses a corn root system lodging resistance measuring device and a measuring method, wherein the measuring device comprises a corn lodging resistance tester, a detachable water tank, a rigid splint and the like, the corn lodging resistance tester adopts a corn stalk lodging resistance tester disclosed in the utility model of CN206804447U, and mainly comprises a tension measurer and a movable slide bar; the detachable sink is composed of two long iron plates and two short iron plates, wherein the long iron plates and the short iron plates are both provided with curled edges, and the short iron plates are also provided with retaining pieces; the rigid splint comprises two semicircular iron sheets. The method for measuring the lodging resistance of the corn root system comprises the steps of firstly utilizing a water tank to fill soil in a designated area until the soil is saturated with water, and then utilizing a corn lodging resistance tester and a rigid splint to measure the side root pulling resistance of the corn in the afternoon. The method is convenient to operate, more accords with the actual situation of corn when the corn roots fall down, and the measured data is more persuasive.
Description
Technical Field
The patent relates to a device and a method for measuring the lateral uprooting resistance of corn.
Background
The measurement work of the lateral uprooting resistance of the corn is needed when the root lodging resistance of the corn is evaluated. The existing measuring method is to vertically pull a corn plant out of the ground by using a root-pulling dynamometer and record the maximum force required for pulling out the ground. However, this method is significantly different from natural lodging in the direction and condition of lodging. It would be desirable if a measuring device and method could be devised that would allow for the artificial and natural lodging to be as consistent as possible in direction and condition.
Disclosure of Invention
Aiming at the defects of the prior art, the novel corn lateral uprooting resistance measuring device and method are simple in structure and convenient to operate.
The technical scheme adopted by the innovation for solving the technical problem is as follows:
the utility model provides an anti side uprooting power measuring device of maize, includes maize lodging resistance tester, detachable type basin, rigidity splint etc..
Corn lodging resistance tester adopt CN206804447U utility model patent corn stalk lodging resistance tester mainly comprises tensile force caliber and removal smooth stalk.
The detachable water tank is characterized in that the detachable water tank is 2m 0.6m 0.4m in overall specification, and is composed of two stainless steel iron plates 1mm in specification, 2m 0.4m and 0.6m 0.4m, the upper ends of the 4 iron plates are respectively provided with an inverted L-shaped curled edge (the length of the turned L-shaped curled edge is equal to that of the iron plate) with the width and the height of 2cm, and the two sides of the stainless steel iron plate with the specification of 0.6m 0.4m are respectively provided with a baffle plate with the length of 5cm 38cm, and the baffle plates are mainly used for preventing the long baffles from outwards inclining when water is poured.
The rigid clamping plates are two semicircular iron sheets with the length of 80cm, and are mainly used for being bound in the long axis direction of the stalks when the corns are pushed and pulled, so that the stalks are prevented from being bent when the corns are pushed and pulled, and the tensile force cannot be completely transmitted to the corn root systems.

FIG. 2 is a three-dimensional view of a short iron plate of the detachable sink of the present invention
FIG. 3 is a three-dimensional view of the rigid splint of the present invention
FIG. 4 is a field assembly drawing of the detachable sink of the present invention
FIG. 5 is a schematic diagram of the corn side-uprooting resistance test of the present invention
In the figure, the corn harvester is provided with a longitudinal curled edge 1, a transverse curled edge 2, a side long iron plate 3, a longitudinal curled edge 4, a side short iron plate 5, a transverse curled edge 6, a blocking piece 7, a rigid clamping plate cambered surface 8, a rigid clamping plate top view 9, a rigid clamping plate side view 10, a leaf-removed corn plant 11, a leaf-removed corn plant 12, a movable sliding stalk 13, a tension measurer 14 and a corn lodging resistance tester 15.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and various modifications or variations (including whether or not a rigid splint is used) can be made by those skilled in the art without inventive efforts based on the technical solution of the present invention.
Detailed Description
Water tank installation: firstly, a ditch with the length, width and height of 2m 0.04m 0.15m is formed between two side lines by a small-sized pickaxe, a ditch with the length, width and height of 0.6m 0.04m 0.15m is formed between two side plants, after the ditching is finished, 4 iron plates are respectively placed in the corresponding ditches, then the long iron plate and the short iron plate are connected, the connected positions are sealed from the inner side by a transparent adhesive tape, and after all the ditches are sealed, the ditches are filled with soil and compacted.
The determination method comprises the following steps: firstly, calculating the required irrigation quantity of a test area reaching the specified required field capacity according to a formula (1), then utilizing a series of equipment such as a water tank, a water pump, a water pipe and the like to irrigate in the afternoon or in the evening of the day, stopping irrigation immediately after the quantity is reached, removing the water tank after the underwater seepage is finished, and measuring the lateral uprooting resistance in the morning of the next day. When the lateral uprooting resistance is measured, firstly removing all leaves of the corn, only keeping a main stem with the height of 1m, then fixing the corn lodging resistance tester and the stem from a first internode of the base part of the stem by using a rigid clamping plate until the main stem is fixed to the highest point of the rigid clamping plate, after the fixation is finished, fixing the corn lodging resistance tester and the stem at a position of the stem 0.8 m higher than the horizontal ground, pulling the corn lodging resistance tester along the long axis direction of the stem after the fixation is finished, stopping pulling the tester after the tester enters a checking state from a testing state, and checking and storing numerical values.
Irrigation quantity = irrigation area soil wetting depth soil volume weight (field water capacity-wilting water content) (formula 1)
The beneficial effect of this innovation type is: the corn lodging measuring instrument is small in design, convenient to operate, more close to the actual conditions of corn lodging, and can be used for directly measuring corn plants in a field. The semicircular iron sheets are designed to conveniently fix and support the corn stalks; the design of the detachable water tank can meet the moisture requirement of corn lodging.
