Description

Technical Field

[0001] The utility model relates to the technical field of soil improvement, in particular to a saline-alkali land soil improvement device. Background Art

[0002] Saline-alkali land refers to the salt content in the soil that affects the normal growth of crops. Saline-alkali soil is formed under certain natural conditions. The essence of its formation is mainly the horizontal and vertical redistribution of various soluble salts on the ground, so that salt gradually accumulates on the soil surface in the salt-collecting area. In order to grow plants in saline-alkali soil, the saline-alkali soil needs to be improved.

[0003] After searching, the utility model with patent number CN216451815U discloses a device that can improve saline-alkali soil, including a saline-alkali land body, the interior of which includes a saline-alkali soil layer, a fine sand layer, a gravel layer, a filter screen and a guide plate from top to bottom. The interior of the saline-alkali soil layer is filled with a flushing pipe, and water is sprayed onto the surface of the saline-alkali soil layer through multiple drip irrigation pipes. Excess water seeps into the saline-alkali soil layer to prevent the soil from returning to alkalinity; the water is passed into the flushing pipe through the outlet pipe and the connecting pipe, so that multiple nozzles spray out the liquid, which can fertilize the saline-alkali soil layer or neutralize the soil, thereby achieving the effect of improving the saline-alkali soil. However, this existing technology cannot break up the soil when improving saline-alkali soil, resulting in water not being able to quickly and fully contact the improved soil, affecting the improvement effect. In addition, when adjusting the pH of saline-alkali soil, the existing technology directly adds fertilizers or chemicals into the pool, causing pollution to the pool. It requires cleaning the pool before using clean water again, which is time-consuming and labor-intensive.
