Device for cultivating fruit trees in saline-alkali soil

A device for cultivating fruit trees in saline-alkali soil belongs to the technical field of saline-alkali soil cultivation and comprises a power supply module, a control mechanism, a first groove body, a second groove body, a first barrel, a second barrel, a first pump body, a second pump body and an insertion pipe, by arranging the buffer soil layer with a certain thickness, on one hand, the influence of the saline-alkali returning phenomenon of the saline-alkali soil on fruit tree growth can be avoided, on the other hand, the fruit trees can obtain improved soil for sustainable survival through continuous treatment, the saline-alkali soil of the orchard can be deeply improved through gradual or global treatment, and after improvement, the yield of the fruit trees is improved. The device can be repeatedly used in other saline-alkali soil, so that the planting cost of fruit trees is reduced, in the planting and saline-alkali soil improvement process, a water source treated by a neutralizer can be repeatedly
