Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drip irrigation system control, in particular to a micro-saline water plus bacteria drip irrigation system and method and computer readable storage medium. BACKGROUND

[0002] As a non-conventional water source, micro-saline water can be used as an alternative water resource for irrigation in arid regions. However, micro-saline water contains a large amount of calcium and magnesium ions, which can easily form calcium and magnesium compounds and deposit in various parts of the drip irrigation system, seriously affecting the normal operation of the drip irrigation system. By injecting an appropriate amount of bacteria into the micro-saline water, the formation of calcium and magnesium deposits can be effectively reduced without causing biological clogging, which provides technical support for using micro-saline water as an irrigation water source in arid regions. Therefore, the type, ratio and activation conditions of the bacteria are crucial for the full utilization of micro-saline water.

[0003] Currently, the long-term and efficient use of micro-saline water drip irrigation systems still needs to be addressed. The existing solutions require a large amount of data support, which is not conducive to popularization and application. For example, a micro-saline water drip irrigation water and fertilizer control method, device and system disclosed in patent publication CN118661526A obtains an optimal drip irrigation strategy to precisely control the drip irrigation flow and salt concentration, ensuring that each drop of water is efficiently absorbed by crops. However, for each field, soil data, crop growth state data and weather data within the irrigation area need to be obtained, and a soil salt spatial distribution map within the irrigation area needs to be drawn. Finally, the control strategy is output in combination with soil characteristics, crop characteristics and weather characteristics. The existing technical solution has complicated steps, and the accuracy of salt distribution needs to be verified. Therefore, there is an urgent need to provide a simple and efficient long-term operation method for micro-saline water drip irrigation systems.

[0004] The type, ratio and addition scheme of the bacteria affect the operation time of the micro-saline water drip irrigation system. The parameters of the bacteria type and ratio method still need to be determined. Currently, there is a problem of relying on manual experience for ratio in water and fertilizer ratio in drip irrigation systems. Therefore, it is necessary to propose a reasonable bacteria ratio calculation logic and automatic system for agricultural operation personnel.

[0005] In summary, there is an urgent need to invent a micro-saline water plus bacteria drip irrigation system and method. SUMMARY
