Description

Technical Field

[0001] The invention relates to the technical field of rice planting, and in particular to a hybridization test box for low-glycemic rice planting and a use method thereof. Background Art

[0002] Low-glycemic rice, also known as "sugar-controlled rice", is a rice variety with a lower glycemic index (GI). This type of rice has a lower glycemic index, which means that it releases sugar more slowly during digestion, helping to keep blood sugar stable and avoid drastic fluctuations in blood sugar after a meal. The research and development of low-glycemic rice is mainly aimed at people who need to manage blood sugar levels, such as diabetics, and consumers who pursue a healthy diet.

[0003] In the process of breeding low-glycemic rice, researchers used technologies such as genome sequencing and QTL positioning to identify and locate key genes that affect the starch properties of rice, such as the Wx gene and the Alg9 gene. These genes are closely related to low-glycemic characteristics. Through molecular marker-assisted selection and gene editing technology, these genes can be accurately improved to create new rice germplasm with low-glycemic characteristics, and then the new rice germplasm with low-glycemic characteristics can be further cultivated through hybrid test boxes.

[0004] After searching, the patent technology with the announcement number CN112219715B discloses a hybridization test box for rice planting and its use method. The hybridization test box for rice planting includes: a lower box body and a base; an upper box body, the upper box body is arranged on the top of the lower box body, the inner part of the lower box body is movably connected with a planting box, and both sides of the top of the lower box body are provided with a fixed structure, and the fixed structure includes a fixing part and a positioning shaft. The hybridization test box, by dividing the box body into two parts, an upper box body and a lower box body, changes the traditional one-piece design into an assembled design. When it is necessary to repair the internal components or carry them, the upper and lower boxes can be disassembled and then operated, making the operation more convenient and easier. Through the fixed structure, the clamping structure and the buffer structure, the test box has multiple functions at the same time, which can well meet people's use needs.

[0005] However, the above hybrid test box still has the following problems: the above hybrid test box waters the seedlings in two areas of the planting box respectively by setting two drainage pipes at the bottom of the water storage tank. Since the positions of the two drainage pipes are relatively fixed, the coverage range is relatively limited. A floodlight installed inside the protective cover is set above the planting box to achieve supplementary lighting for the seedlings. Since the floodlight is blocked by the drainage pipe, the supplementary lighting effect is insufficient, and it is covered by the protective cover, which affects the heat dissipation.

During the stirring process, the rocker 43 drives the limiting shaft 44 to rotate circumferentially around the axis of the shaft rod 41. Since the limiting shaft 44 is limited in the limiting groove 82, the cross frame 81 can be pushed by the limiting shaft 44, and the sliding sleeves 83 at both ends of the cross frame 81 slide on the guide rods 11, so that the limiting groove 82 can reciprocate horizontally.

[0041] See also Figure 4 and Figure 8 The swing arm 5 includes a frame 51, a connecting plate 52 is fixed at one end of the frame 51, a shaft sleeve 53 is fixed at the end of the connecting plate 52 away from the frame 51, the shaft sleeve 53 is rotatably sleeved outside the shaft rod 41, a swivel 54 is fixed at the end of the shaft sleeve 53, a pull rod 55 is radially fixed to the outer side of the swivel 54, a vertically arranged fixed column 56 is fixed at the end of the pull rod 55 away from the swivel 54, and the lower end of the fixed column 56 is hinged to the push-pull rod 86.

[0042] It should be noted that the connecting plate 52 on one of the swing arms 5 is in a straight line shape, and the connecting plate 52 on the other swing arm 5 is in a Z shape. This design can ensure that the two swing arms 5 are at the same height position, thereby making the fill light range of the fill light assembly 6 on the two swing arms 5 consistent with the water spray range of the spray assembly 7.

[0043] See also Figure 8 and Fig. 9The fill light assembly 6 includes a lamp board 61, which is fixedly embedded in the inner bottom side of the frame 51, a lamp tube 62 is fixed at the bottom of the lamp board 61, and a plurality of equidistantly distributed heat dissipation fins 63 are fixed on the top surface of the lamp board 61.

When the control valve is opened, the water in the water storage chamber can be passed into the main conduit 71, and then diverted to each nozzle 74 by several branch pipes 73 on the top of the main conduit 71, so as to realize the spraying operation of seedlings. At the same time, the water supplied by the main conduit 71 to the nozzle 74 can further cool down the heat absorbed by the heat dissipation fin 63 when the lamp board 61 is working, thereby improving the heat dissipation efficiency of the lamp tube 62.

[0045] See also Figure 1 and Figure 3 The driving mechanism 10 includes a second motor 101, which is fixed to the bottom cavity of the box body 1. A gear 102 is fixed to the output end of the second motor 101. A circle of annular teeth 22 is fixed to the outer side of the bottom of the planting barrel 2. The gear 102 is meshed with the annular teeth 22. After the rice seedlings in the two lower planting areas reach the amount of supplementary light or water, the second motor 101 works to drive the gear 102 to rotate. The gear 102 is meshed with the annular teeth 22 on the outer side of the planting barrel 2, driving the planting barrel 2 to rotate on the tray 9, thereby switching the other two planting areas to the bottom of the two swing arms 5.

[0046] The working principle and use process of the present invention are as follows: the first motor 3 drives the shaft 41 to rotate, and the stirring rod 42 outside the shaft 41 can rotate and stir the spray water in the water storage chamber. During the stirring process, the rocker 43 drives the limit shaft 44 to rotate circumferentially around the axis of the shaft 41. Since the limit shaft 44 is limited in the limit groove 82, the limit shaft 44 can push the cross frame 81, and the sliding sleeves 83 at both ends of the cross frame 81 slide on the guide rod 11, so that the cross frame 81 can reciprocate horizontally. Under the hinged action of the two ends of the push-pull rod 86 and the hinge seat 85 at the outer end of the thrust rod 84 and the fixed column 56, the two rotating rings 54 are driven to rotate synchronously and periodically, that is, the two swing arms 5 can swing back and forth above the planting barrel 2, and the swing range of the two swing arms 5 just covers the two opposite planting areas below;

[0047] The fill light assembly 6 can provide fill light to the planting area below through the lamp tube 62 at the bottom of the lamp board 61 during the swinging of the swing arm 5, so as to promote the growth of the rice seedlings under the lighting conditions, and the spray assembly 7 can spray the water in the water storage chamber to the planting area below during the swinging of the swing arm 5, so as to provide sufficient water source for the rapid growth of the rice seedlings.
