Abstract

The invention discloses a saline-alkali soil salt water desalination and supplementary irrigation device which comprises a salt water source, a wind-solar complementary power generation system, a water lifting device, a desalination distillation device and a field supplementary irrigation system. The desalination distillation device distills saline water to obtain fresh water and conveys the fresh water to the field supplementary irrigation system, the field supplementary irrigation system conveys the fresh water to the field, the problem of fresh water shortage of the saline-alkali soil is solved, the wind-solar complementary power generation system supplies energy to the water lifting device, the desalination distillation device and the field supplementary irrigation system, and independent laying of power transmission equipment and the like is reduced. The method can be applied to barren areas lacking electric power facilities; the desalination distillation device is high in evaporation intensity and desalination water collection efficiency, salt in salt water can be separated and extracted, the total salt content of the saline-alkali soil is reduced, the saline-alkali soil is treated, the crop growth environment is improved, and crop harvest is improved.

Description

technical field [0001] The invention relates to the technical field of farmland water conservancy, in particular to a salt water desalination supplementary irrigation device for saline-alkali land. Background technique [0002] Soil salinization is a worldwide problem. About 20% of the irrigated agricultural land in the world is affected by salinization. Factors such as drought, unreasonable farming, backward drainage equipment, facility cultivation and other factors lead to the increasing secondary salinization of the soil, and the high salinity in the soil endangers the growth of rice seedlings. . The limited land determines that it is necessary for people to carry out research and practice on saline-alkali soil restoration, so as to restore and improve saline-alkali soil, make it suitable for the growth and development of crops, facilitate agricultural cultivation, improve regional economy, and promote regional social development. [0003] Hundreds of years of experienc...
