[0016] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] like Figure 1 to Figure 2 As shown, in order to achieve the above purpose, the utility model is implemented through the following technical solutions: a system for improving saline-alkali land by using salt-alkali tolerant rice, which is composed of a saline-alkali land rice field 1, a saline-alkali land separation pool 2, a salt-alkali tolerant planting frame 3 and a drainage step 4;

[0019] It is characterized in that the saline-alkali land separation pool 2 is arranged in the outer circle of the saline-alkali land rice field 1, a separation ridge 11 is arranged between the saline-alkali land separation pool 2 and the saline-alkali land rice field 1, a drainage step is arranged on the separation ridge, the bottom elevation of the saline-alkali land separation pool is lower than the bottom elevation of the saline-alkali land rice field, a salt-alkali resistant planting frame 3 is fixedly installed on the saline-alkali land separation pool 1, salt-alkali resistant non-rice plants are planted in the salt-alkali resistant planting frame, and salt-alkali resistant rice is planted in the saline-alkali land rice field, a water pump 12 is arranged in the saline-alkali land separation pool, and the water outlet pipe of the water pump is connected to the separation ridge.

[0021] The plants planted in the salt-alkali tolerant planting frame are Suaeda salsa or alfalfa.

[0022] The utility model utilizes salt-alkali tolerant rice to improve saline-alkali land system. The irrigation water in the rice field is discharged into the saline-alkali land separation pool. The salt-alkali tolerant planting frames on the saline-alkali land separation pool are planted with highly salt-alkali tolerant plants, such as Salicornia herba, which will take away a large amount of salt and alkali during their growth and harvesting. The salinity in the saline-alkali land separation pool and the saline-alkali land rice field is roughly equal. After continuous rotation of crops and circulating water changes, the salinity in the saline-alkali land rice field is reduced.

[0023] The above is only a preferred embodiment of the utility model, and does not limit the structure of the utility model in any form. Any simple modification, equivalent change or modification made to the above embodiment based on the technical essence of the utility model still falls within the scope of the technical solution of the utility model.
