Description

Technical Field

[0001] The utility model relates to the technical field of rice breeding, and specifically relates to a rice breeding device capable of preventing stems from falling over. Background Art

[0002] Excessive height of rice plants is one of the main factors leading to stem lodging. When the plant height exceeds a certain range, the center of gravity of the rice moves upward, and the stem is more likely to bend or break. For example, some traditional tall rice varieties can reach a plant height of 1.5-2 meters, and the risk of lodging is significantly increased. Slender stems: The thickness of the stem directly affects its mechanical strength. Slender stems are unable to withstand the weight of the rice panicle and external forces. Generally speaking, stem thickness is positively correlated with lodging resistance, and thicker stems can provide better support.

[0003] In the prior art, when breeding rice, rice plants of different plant heights cannot be supported at different positions, resulting in rice lodging. The present invention solves the above problem. Utility Model Content

[0004] The utility model aims to solve the technical problem that the prior art cannot support rice plants of different plant heights at different positions during rice breeding, resulting in rice lodging, and thus provides a rice breeding device that can prevent the stems from falling over.

[0006] Preferably, two brackets are provided, and the two brackets are respectively connected to both sides of the seedling tray. The upper end of the bracket is rotatably connected to the roller shaft end, the middle part of the pull rope is located in the roller groove, and the bracket is connected to a cross bar, and the pull rope can be fastened to the cross bar.

[0007] Preferably, a groove is provided on the upper surface of the seedling tray, and the seedling supporting frame can be placed in the groove.

[0008] Preferably, the side walls of the breeding box are inlaid with thermal insulation glass.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The seedling tray that slides inside the breeding box is convenient for planting, pollination and harvesting. The height of the seedling support frame can be adjusted by pulling the rope, so that the seedling support frame can be moved to the point where the rice is prone to breaking to provide support and prevent the rice from falling over.

[0011] By cooperating with the pull rope and the roller, the displacement of the seedling support frame can be conveniently controlled. The pull rope is fixed by the cross bar, and the pull rope will not interfere when the seedling tray slides. BRIEF DESCRIPTION OF THE DRAWINGS
