Problems solved by technology

If corn lodging occurs, the experiment will have to be terminated, and the experiment can only be carried out again in the next year, which will undoubtedly greatly increase the time cost of breeding, and will also bring huge waste of manpower and material resources

Embodiment 1

[0037] This embodiment relates to an anti-lodging system for corn in a plot breeding test field. The system is suitable for plot breeding test plots with an area of ​​several square meters (such as 4 or 5 square meters), and is particularly suitable for high-yielding corn breeding tests in the southern Hebei and North China plains. use. However, it is undeniable that the anti-lodging system based on the design idea of ​​the present invention can also be used in small corn breeding test fields in other regions to reduce or even avoid the problem of corn lodging due to wind. In addition, in addition to corn, it is also possible to expand and apply the lodging prevention system of the present invention to other crop breeding, which is not limited in this embodiment.

[0038] It should be declared that, except for the structural features and their restrictions given in this paper, other undescribed ones can be adopted by conventional technical means in the prior art.

[0039] Spe...

Embodiment 2

[0053] This embodiment relates to an anti-lodging system for corn in a plot breeding test field, which is roughly the same in structure as the anti-lodging system in Embodiment 1, except that Figure 5 to Figure 8 As shown, the backing plate 1 of this embodiment includes two sections that are plugged and connected, and each section of the backing plate 1 is provided with a chute 6 and at least one set of connection units, and the chute on each section of the backing plate 1 6 is provided with a sliding connector 8, and a binding belt 15 is provided at the connecting unit on each section of the backing plate 1.

[0054] As for the connection of two sections of backing board 1, specifically as a preferred implementation form, in this embodiment, one end of one section of backing board 1 is integrally constructed with a plug-in end 11, and the outer arc surface of the plug-in end 11 It is provided with a plurality of protruding clamping strips 12. One end of the other backing bo...

Abstract

The invention provides an anti-lodging system for corn in a plot breeding test field, which includes several backing boards, restraint belts, sliding connectors, linkage boards and fixed rods. The chute provided by the closed end, and a plurality of pairs of connecting units arranged at intervals, a number of binding belts corresponding to the connecting units, at least one sliding connecting piece is arranged on each backing plate, and the sliding connecting piece One end can slide along the chute, and the other end is configured with a series connection hole. The linkage plate can connect the sliding connectors at the same position on each backing plate through the series connection hole. One, and detachably connected with the linkage plate. The anti-lodging system for corn in a plot breeding test field of the invention can minimize or even avoid the lodging of corn, and can advantageously ensure the normal completion of a breeding test.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding, in particular to an anti-lodging system for corn in a plot breeding test field. Background technique [0002] In corn breeding, plot breeding test is a kind of variety inspection method that is often used. According to the design requirements, the area of ​​the plot breeding test field varies from large to small. The large one has dozens of square meters, and the small one only has a few square meters. Among them, for a small-area experimental field, that is, a breeding experimental field of several squares, corn is generally sown by hand-held on-demand, and the distance between adjacent plants can be set at the conventional corn spacing. In my country's North China Plain, such as the southern Hebei Plain, corn is mostly sown in early summer and harvested in autumn, and summer and autumn are the seasons with more wind and rain, especially in autumn when the corn plants are tall and ...
