Description

Technical Field

[0002] Cotton is the most important cash crop and occupies an important position in the world and my country's national economy. With the reduction of cultivated land, cotton planting has gradually concentrated on saline-alkali land, so these saline-alkali lands have huge development potential. Although cotton is a relatively salt-tolerant crop, according to current research, the high concentration of salt in most saline-alkali lands is still an important factor restricting the normal growth of cotton. Therefore, improving and improving the salt-alkali resistance of cotton varieties has become one of the key points of cotton breeding. my country has collected and preserved abundant cotton germplasm resources. How to quickly and accurately identify salt-tolerant materials from these materials? In general, experimenters screen and identify their salt tolerance during the germination and seedling stages, which not only saves time but is also accurate. However, there are still many deficiencies in the test equipment currently used in salt tolerance research experiments.

[0003] Traditional test equipment cannot intuitively and comprehensively compare the salt tolerance of cotton seedlings at different stages and the test results of cotton seedlings at the same stage under different saline concentrations. Generally, to achieve the above test objectives, operators are required to repeatedly mix the saline solution many times, which is very cumbersome.

The movement of the movable block will drive the flow of brine in the test box, remix the precipitated salt, and ensure that the concentration of the brine is within the standard range. In this case, the brine concentration always remains in a constant range, and the test results are more accurate and more convincing. BRIEF DESCRIPTION OF THE DRAWINGS

Under the action of the transmission rod 36, the driving rod 37 drives the movable arm 19 at the end of the driving arm 4 to move back and forth horizontally. During this process, if a part of the water in the test box 5 is evaporated for a long time, the floating block 24 will follow the liquid level in the test box 5 to drop, and the floating block 24 will drive the floating rod 8 to move downward. During the horizontal movement of the extrusion rod 15, the extrusion rod 15 located above the floating rod 8 will not be blocked by the floating rod 8, and the extrusion rod 15 and the immersion rod 15 will not be blocked by the floating rod 8. The movable arm 19 contacts the mounting head 16 to drive the piston block 32 at the end of the piston column 30 to move laterally, and the air in the air guide tube 25 is compressed, thereby increasing the pressure in the impact head 26, and then the movable block 43 moves. The movement of the movable block 43 drives the flow of brine in the test box 5, remixing the precipitated salt, and ensuring that the concentration of the brine is within the standard range. In this case, the concentration of the brine is always kept within a constant range, and the test results are more accurate.
