Plant irrigation system

Abstract

The invention discloses a plant irrigation system. The plant irrigation system comprises a water storage system, a control unit, an irrigation waterway and sensor units, wherein the water storage system is connected with an inlet and an outlet of the irrigation waterway and a tap water source, and is provided with a float valve which opens the tap water source to replenish water into the water storage system when the water level in the water storage system is lower than one set position; the control unit is used for controlling water supply and drainage according to trigger signals sent by the sensor units; the irrigation waterway comprises a plurality of basin-shaped containers, and lower ends of the containers are contacted with the water source in the irrigation waterway to supply the water to the containers; and the sensor units are positioned in the containers, and send the trigger signals to the control unit by sensing the status of water storage in the containers. A water pump is arranged at the joint of the water storage system and the inlet of the irrigation waterway, wherein when sensing the lack of water in the containers, the senor units send water supply signals to the control unit, and the control unit controls the water pump to open the irrigation waterway to supply the water; and when excessive water in the irrigation waterway flows back to the water storage system through the outlet, the control unit sends a signal to the water pump to shut off the water source.

Description

Technical field [0001] The invention relates to the technical field of irrigation in facility agriculture, in particular to a plant irrigation system. Background technique [0002] Water is very important for plant cultivation and production. It is a regular work in horticultural plant cultivation and production. It not only takes a long time and requires a lot of labor, but also with the sharp decrease in water supply, the requirements for horticultural plant irrigation technology are also constant improve. Based on the characteristics of plants' living habits, growth and development rules, rational use of limited water resources, timely irrigation, and active development of water-saving agriculture are particularly important for a large agricultural country such as our country that lacks water resources. [0003] Currently, the main irrigation methods used include: [0004] ①Surface irrigation. Surface irrigation requires limited equipment, low investment and low cost. It is one ...

Problems solved by technology

However, the equipment investment is large, and in order to ensure that the dripper is not blocked, the requirements for water quality are relatively strict, and the water filtration equipment must be sophisticated, which costs a lot of money.

[0008] In addition, no matter which of the above-mentioned irrigation methods is used, the grower is required to have a certain level of agronomy, to understand the concentration of the nutrient solution in the water, and the ratio of nutrients, and the agronomist is required to maintain it frequently, which increases the cost and makes the planting of the product interesting. , Participation is greatly reduced; at the same time, due to the frequent water cycle (calculated in hours), it will consume a lot of electricity, and it is difficult to achieve the effect of saving money
