Vegetable greenhouse automatic watering and pesticide filling system

Abstract

The invention discloses a vegetable greenhouse automatic watering and pesticide filling system which comprises a water storage tank, a water pipe, an electromagnetic valve, a pesticide storage device,a spraying nozzle, a humidity sensor, a water pump and a circuit system. The water storage tank is located in a high place. The spraying nozzle is connected with the water storage tank through the water pipe. The electromagnetic valve and the pesticide storage device are installed on the water pipe. The pesticide storage device is located in the water flowing direction of the electromagnetic valve. The humidity sensor is inserted in soil. The circuit system comprises a humidity detecting module, a main controller, a water pump driver and an electromagnetic valve driver. The humidity detectingmodule, the water pump driver and the electromagnetic valve driver are all electrically connected with the main controller. By means of the vegetable greenhouse automatic watering and pesticide filling system, watering can be conducted in a greenhouse according to the soil humidity in the greenhouse, pesticides needed by planted vegetables can be automatically and evenly scattered in the soil along with water, and the system is quite suitable for the vegetable greenhouse and has quite good popularization performance.

Description

technical field [0001] The invention relates to the technical field of automatic watering, in particular to an automatic watering system for vegetable greenhouses. Background technique [0002] Due to historical, conceptual and technical reasons, there is a big gap between my country's traditional agricultural machinery and developed countries, and it is far from being able to meet the requirements of agricultural scientific and technological progress. At present, the irrigation of agricultural greenhouses is mostly manual and subjective irrigation, and whether to irrigate is judged by experience and estimation, which lacks scientific basis and causes waste of water resources. More importantly, agricultural irrigation requires a lot of labor and is inefficient, resulting in a huge waste of labor and restricting social development. At present, the irrigation methods commonly used in agricultural greenhouses include flood irrigation, watering, sprinkler irrigation, drip irrig...

Problems solved by technology

[0002] Due to historical, conceptual and technical reasons, there is a big gap between my country's traditional agricultural machinery and developed countries, and it is far from being able to meet the requirements of agricultural scientific and technological progress.

At present, irrigation in agricultural greenhouses is mostly manual and subjective irrigation. Judging whether to irrigate based on experience and estimation lacks scientific basis and causes waste of water resources.

More importantly, agricultural irrigation requires a lot of labor and is inefficient, resulting in a huge waste of labor and restricting social development.

At present, the irrigation methods commonly used in agricultural greenhouses include flood irrigation, watering, sprinkler irrigation, drip irrigation, micro-irrigation, seepage irrigation, negative pressure irrigation and other methods. They all have the disadvantages of requiring manual management, serious waste of resources, and limited application range.
