Description

Technical Field

[0001] The invention belongs to the technical field of agricultural water-saving irrigation, and in particular relates to a water-fertilizer-gas integrated mixer. Background Art

[0002] China is a major agricultural country. The Ministry of Water Resources stated that in 2021, my country's agricultural water consumption reached 364.43 billion cubic meters, accounting for 61.5% of the total water consumption. Since crops require a large amount of water, and traditional irrigation technology is prone to waste water resources, micro-irrigation can be used according to crop needs. Through the pipe system and the emitters installed on the final stage of the pipe, water and nutrients required for crop growth can be delivered directly to the soil near the crop roots at a smaller flow rate, evenly and accurately.

[0003] Most existing micro-irrigation devices provide water and fertilizer to plant roots. However, the root cells of plants also contain cells with organelles called mitochondria, which are the main site of aerobic respiration in plants. Therefore, the roots need oxygen. Therefore, gas needs to be delivered to the plant roots during the micro-irrigation process. However, the gas and fertilizer of the existing water, fertilizer and gas micro-irrigation devices are not added at the same time. The fertilizer is not subjected to the high-speed shearing and high-speed integrated stirring of the gas-liquid mixing pump, and a stable water-gas-fertilizer integrated mixture cannot be formed, which affects the micro-irrigation effect.
