Description

Technical Field

[0001] The invention relates to the technical field of agricultural irrigation, and in particular to an intelligent watering control system for agricultural production. Background Art

[0002] In agricultural production, the rational use and management of water resources are crucial. Traditional irrigation methods often have the problem of water waste, such as over-irrigation or under-irrigation, which not only affects the growth of crops, but may also lead to water shortages. The rational application of fertilizers is crucial to improving crop yields and quality. However, traditional fertilization methods often have problems of fertilizer waste and environmental pollution. For example, excessive fertilization may lead to soil pollution and eutrophication of water bodies. Irrigation equipment such as sprinklers are prone to blockage during use, which not only affects the irrigation effect, but also may increase maintenance costs. With the development of precision agriculture, agricultural production has higher and higher requirements for the accuracy of irrigation and fertilization. Traditional manual management methods are difficult to meet this demand. Therefore, an intelligent watering control system for agricultural production is proposed. Summary of the invention

[0003] The present invention aims to solve the technical problem of how to dredge the nozzle after it is blocked and to mix water and fertilizer for watering when the water quality is abnormal, thereby providing an intelligent watering control system for agricultural production.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an intelligent watering control system for agricultural production, including a blockage dredging module, a water-fertilizer ratio fertilization module, and a watering module. The blockage dredging module is arranged in the farmland, and is used to detect whether the nozzle is blocked. It is used to dredge the nozzle after the nozzle is detected to be blocked. The water-fertilizer ratio fertilization module is arranged in the farmland, and is used to determine whether the water quality is abnormal. It is used to proportion water and fertilizer after determining that the water quality is abnormal. It is used to fertilize crops after proportioning water and fertilizer. The watering module is arranged in the farmland, and is used to detect the amount of irrigation water in the soil. It is used to water crops.

[0005] Through the setting of the blockage dredging module, the working status of the nozzle is monitored in real time to detect whether there is a blockage. Once the nozzle is detected to be blocked, the blocked nozzle is cleared in time to ensure that the irrigation system is unobstructed. The water-fertilizer ratio fertilization module monitors the irrigation water source in real time to determine whether the water quality is abnormal. After detecting abnormal water quality, the water and fertilizer are automatically adjusted to ensure that the crops get sufficient nutrients, and the well-proportioned water-fertilizer mixture is transported to the farmland to fertilize the crops. Intelligent fertilization improves fertilizer utilization, greatly reduces the need for manual intervention, and reduces labor costs. By monitoring the amount of irrigation water in the soil, the water demand of crops can be understood. According to the real-time monitoring results of soil moisture, crops are accurately watered to ensure that crops get the right amount of water and avoid water waste and over-irrigation. Through precision irrigation and intelligent fertilization, water waste is minimized, irrigation efficiency is improved, and the problem of water shortage is alleviated. At the same time, precise water supply and fertilization according to the needs of crops are carried out, which helps the healthy growth of crops, thereby increasing yield and quality, greatly improving the efficiency and quality of agricultural production, and promoting the sustainable development of agriculture.
