Problems solved by technology

Ground irrigation is the oldest and most common irrigation method, which requires less preparation; sprinkler irrigation is an irrigation method that uses special equipment such as sprinklers to spray pressurized water into the air, and forms water droplets to fall on the ground sprinkler irrigation surface and crop surface; Underground irrigation, underground irrigation is to bury the pipes in the soil, and the water seeps out from the pipes to moisten the soil for water supply irrigation. Difficult, so it is difficult to promote on a large scale

Abstract

The invention discloses a water-saving irrigation system. The system comprises a rainwater collecting device, a nutrition fertilizing device, an energy-saving device, drip irrigation devices and a control box. The rainwater collecting device comprises a rainwater collecting pool, a water inlet pipe is arranged on the top of the rainwater collecting pool, and a buoyancy ball valve is arranged at the lower end of the water inlet pipe. Each drip irrigation device comprises a main pipe and a humidity sensor, wherein the main pipe is connected with a plurality of branch pipes at equal intervals; the drip irrigation devices are uniformly arranged on the branch pipes, and the humidity sensors are electrically connected with the control box. The invention also discloses an irrigation method of thewater-saving irrigation system. The system can collect rainwater for irrigation so as to effectively reduce the water consumption. By adopting the water-saving irrigation control system, the irrigation amount can be effectively controlled, the water-saving effect of the water-saving irrigation control system is further improved, and fertilization can be carried out during irrigation.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to a water-saving irrigation system and method. Background technique [0002] my country is a large agricultural country, and the agricultural water consumption accounts for 68% of the national water consumption, of which the irrigation water consumption accounts for more than 90% of the agricultural water consumption. However, due to the increasingly serious waste and pollution of water resources, there is a serious shortage of agricultural water resources. Therefore, it is imperative to reform agricultural irrigation technology and develop intelligent water-saving irrigation. [0003] At present, my country's agricultural production mode has changed greatly, and the corresponding agricultural water-saving irrigation control technology is still immature, and the agricultural infrastructure is weak. Most technical systems are still in the stage of theoretical research and trial ...
