Description

Technical Field

[0001] The present invention relates to the technical field of drip irrigation system control, and in particular to a brackish water bacteria-added drip irrigation system and method and a computer-readable storage medium. Background Art

[0002] As an unconventional water source, brackish water can be used as an alternative water resource for irrigation in arid areas. However, brackish water contains more calcium and magnesium ions, which can easily form calcium and magnesium compounds in the drip irrigation system and deposit in various places of the drip irrigation system, seriously affecting the normal operation of the drip irrigation system. By injecting an appropriate amount of bacterial agents into brackish water, the formation of calcium and magnesium precipitation can be effectively reduced without causing biological blockage, which provides technical support for the use of brackish water as an irrigation water source in arid areas. Therefore, the type, ratio and activation conditions of bacterial agents are crucial to the full utilization of brackish water.

[0003] At present, the problem of long-term efficient use of brackish water drip irrigation systems remains to be solved. The existing solutions require too much data support, which is not conducive to promotion and application. For example, the patent publication number CN118661526A is a brackish water drip irrigation water and fertilizer control method, equipment and system. By obtaining the optimal drip irrigation strategy, the drip irrigation flow and salt concentration are accurately controlled to ensure that every drop of water is efficiently absorbed by the crop. However, for each field, it is necessary to obtain soil data, crop growth status data, and meteorological data in the irrigation area, and at the same time, it is necessary to draw a spatial distribution map of soil salt in the irrigation area, and finally output the control strategy in combination with soil characteristics, crop characteristics and meteorological characteristics. The existing technical solutions have cumbersome steps, the accuracy of salt distribution needs to be verified, and the accuracy of model analysis also needs to be verified. Therefore, it is urgent to provide a simple, efficient and popularizable long-term operation method for brackish water drip irrigation systems.

[0004] The type, ratio and addition scheme of microbial agents affect the operation time of the brackish water drip irrigation system. The type of microbial agents and the parameters of the ratio method still need to be clarified. At present, there is a common problem of relying on manual experience in the water-fertilizer ratio of drip irrigation systems. Therefore, it is urgent to propose a reasonable microbial agent ratio calculation logic and automation system to facilitate the operation of agricultural operators.

[0005] In summary, there is an urgent need to invent a brackish water and bacteria drip irrigation system and method. Summary of the invention

[0006] In order to improve or even solve at least one problem in the prior art, the present invention provides a brackish water bacteria-added drip irrigation system and method.

[0037] The present invention is further configured as follows: the effective maintenance period T of the bacterial agent is 20 days.

[0038] The present invention is further configured as follows: the bacterial agent used is Bacillus subtilis strain DSM 10.
