Having described the general principles of the invention, reference will now be made in detail to various non-limiting embodiments of the invention, examples of which are illustrated in the accompanying drawings.
Example one
Referring to the attached figure 1, the invention provides a water-saving and salt-inhibiting irrigation and drainage cooperative control method, wherein the method is applied to a water-saving and salt-inhibiting irrigation and drainage cooperative control system, and the method specifically comprises the following steps:
step S100: obtaining a first irrigation and drainage pattern set, wherein the first irrigation and drainage pattern set comprises a first irrigation and drainage pattern and a second irrigation and drainage pattern;
specifically, the water-saving salt-inhibiting irrigation and drainage cooperative regulation and control method is applied to the water-saving salt-inhibiting irrigation and drainage cooperative regulation and control system, water footprint data of crop growth in different irrigation and drainage modes can be obtained through rapid calculation based on the soil conditions around the crops, the optimal irrigation and drainage mode of the crops is determined based on the accurate water footprint data, meanwhile, the optimal coverage scheme of the crops is determined based on soil salt inhibition tests with different coverage materials and different coverage amounts, and the irrigation and drainage cooperative regulation and control is performed in combination with the crop yield. And determining the first irrigation and drainage pattern set through data search and analysis, wherein the first irrigation and drainage pattern set comprises a first irrigation and drainage pattern and a second irrigation and drainage pattern. Such as shallow water service irrigation, shallow wet irrigation, controlled irrigation and impounded water controlled irrigation. And providing a test design reference for a subsequent system to calculate the water footprints of the crops under different irrigation and drainage modes by obtaining the first irrigation and drainage mode set.
Step S200: respectively calculating and obtaining a first water footprint and a second water footprint of a first crop according to the first irrigation and drainage mode and the second irrigation and drainage mode to form a first water footprint set, wherein the first water footprint set corresponds to the first irrigation and drainage mode set in a one-to-one mode;
step S300: determining a first crop irrigation and drainage mode according to the first water footprint set;
specifically, different irrigation and drainage mode tests are designed respectively, and then first crop growth water footprints corresponding to different irrigation and drainage modes are calculated. The first crop refers to any crop to be intelligently regulated by using the water-saving salt-inhibiting irrigation and drainage cooperative regulation and control system, such as rice, corn and the like. The water footprints of the first crop make up the first set of water footprints under different fill and drain mode test conditions. And the water footprints in the first water footprint set correspond to the irrigation and drainage modes in the first irrigation and drainage mode set one by one. For example, under the condition of drip irrigation, the original irrigation system is adjusted under the condition of reduced irrigation, the irrigation frequency is reduced from a small amount of high-frequency irrigation to increase the irrigation quantity, the salt content is promoted to move downwards, the irrigation frequency in winter and autumn is reduced, a drainage system is designed and other engineering measures are taken, and finally, the purpose of once-through autumn and winter irrigation in 2-3 years is achieved. Water footprints of crops under different irrigation and drainage modes are obtained through calculation, and accurate, visual and reliable data basis is provided for subsequently determining the optimal water-saving irrigation and drainage mode.
And further comparing the water footprint data in the first water footprint set, screening a corresponding irrigation and drainage mode when the water footprint value is minimum, and taking the irrigation and drainage mode as a first crop irrigation and drainage mode of the first crop. In addition, soil salinity under different irrigation and drainage modes is detected, and the first crop irrigation and drainage mode is adjusted according to a soil salinity detection result. That is to say, under the first crop irrigation and drainage mode finally determined by the system, the generation process of the first crop not only has good water saving effect, but also can not cause the increase of soil salinity. The water footprint of the first crop is reduced through a proper irrigation and drainage mode, and further the technical effects of water saving and emission reduction are achieved.
Step S400: performing a salt inhibition test on first soil of the first crop to obtain a first salt inhibition test result;

For example, the soil is covered by fine sand and straws, and meanwhile, the covering amount of each group of covering materials is further set to be different in gradient. In addition, the salt content of the soil in the plough layer is ensured to be within the normal development range of the crops by combining the cultivation system and adopting deep ploughing and winter and autumn irrigation to move down the salt content.

That is, the salinity in the soil can be obtained based on the effect of soil salinity on crop yield and crop yield. In addition, accurate data of the salinity in the soil can be obtained through test detection.
