Salinity control system of saline and alkaline land based on Internet of Things

Abstract

The invention relates to the technical field of improvement of saline and alkaline land and particularly relates to a salinity control system of a saline and alkaline land based on Internet of Things. The salinity control system of the saline and alkaline land based on the Internet of Things is provided with an Internet of Things terminal management controller which is connected with an intelligent irrigation cloud data center, and can also provide services for a user through an intelligent irrigation cloud service platform, so that acquisition and high-speed transmission of agricultural conditions and soil information of the saline and alkaline land is effectively realized; and after data is intelligently analyzed, an irrigation model is downloaded to the Internet of Things terminal management controller, so that intelligent irrigation is realized. The saline and alkaline land is irrigated through an irrigation device so that moisture of soil reaches a saturated state, and then soil salt is dissolved into water to form saturation and then is permeated and discharged into a filter material wave tube; and then water is treated through desalting treatment equipment and then returns back to a water collection box again to be used for irrigating, so that water resources are greatly saved.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to a saline-alkali soil salt control system based on the Internet of Things. Background technique [0002] In some western cities in my country, the area of ​​salinized soil is relatively large, and there are many types of salt composition. Among the existing cultivated land, the area affected by different degrees of salinization accounts for a large proportion of the total cultivated land area. It is necessary to carry out these agricultural water and soil Irrigation is used to solve the problem of poor water and soil, especially the current situation of irrigation but no drainage in the Hetao area of ​​Inner Mongolia. At present, the drainage system in my country mainly includes open ditch drainage system, concealed pipe drainage system and shaft drainage system. The traditional drainage system is in the case of bare land. Flood irrigation is carried out on th...

[0002] In some western cities in my country, the area of ​​salinized soil is relatively large, and there are many types of salt composition. Among the existing cultivated land, the area affected by different degrees of salinization accounts for a large proportion of the total cultivated land area. It is necessary to carry out these agricultural water and soil Irrigation is used to solve the problem of poor water and soil, especially the current situation of irrigation but no drainage in the Hetao area of ​​Inner Mongolia. At present, the drainage system in my country mainly includes open ditch drainage system, concealed pipe drainage system and shaft drainage system. The traditional drainage system is in the case of bare land. Flood irrigation is carried out on the field to make the soil water saturated, and then the soil salt dissolves into the water to form saturated infiltration and drains into the drainage ditch, so as to achieve the purpose of salt drainage. This type of drainage can effectively remove the salinity of the soil, but it has many disadvantages , the degree of intelligence is low, manual inspection is required during irrigation, and manual control of the irrigation system wastes a lot of human and financial resources. In addition, an optimized irrigation scheme cannot be formed, resulting in a lot of waste of resources
