[0002] Alfalfa has oval seeds, 1-2.5 mm long, smooth, yellow or brown. It flowers from May to July and fruits from June to August. It is widely cultivated as fodder and pasture in Eurasia and countries around the world, but there are still certain requirements for the selection of the planting environment.

[0003] Saline-alkali land is a general term for both saline and alkaline land. Saline soil mainly refers to saline soil with high chloride or sulfate content, which is alkaline, but its pH value is not necessarily high. Alkaline land refers to soil containing carbonates or biphosphates, with a higher pH value, making it alkaline. Saline-alkali land has low organic matter content, low soil fertility, poor physical and chemical properties, and contains more harmful anions and cations, making it difficult for crops to germinate. Saline-alkali land accounts for nearly 80% of my country's arable land area, making the planting of alfalfa in saline-alkali land unavoidable. Therefore, it is necessary to study the impact of the pH value of saline-alkali land on alfalfa growth when planting alfalfa in saline-alkali land. Utility Model Content

[0004] The purpose of this invention is to provide an alfalfa salt-alkali tolerance testing device to solve the problem mentioned in the background art that it is necessary to study the effect of the pH value of the saline-alkali land on alfalfa growth when planting alfalfa in saline-alkali land.

A fixing block is fixedly connected to the top of the mounting plate. A plug groove is provided on one side of the fixing block. A slide groove is provided on one side of the tray. A slider is slidably connected to the inner side of the slide groove. A fixing rod is glued and fixedly connected to the top of one end of the slider. A pin is integrally formed on one side of the fixing rod.

[0010] Preferably, the fixing rod and the pin are both made of rubber, the inner wall size of the groove matches the outer wall size of the slider, and the slider is a T-shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, culture solutions of different salt and alkali concentrations are placed in different fixed tanks. Then, the mounting plates at both ends of the support frame are inserted into the mounting tanks. The outer walls of the mounting plates fit against the inner walls of the mounting tanks, and both are trapezoidal structures, ensuring stable installation. Alfalfa seeds are then placed in cultivation bowls for cultivation, with the culture solution entering the bowls.
