Description

Technical Field

[0001] The invention belongs to the technical field of fruit tree irrigation and fertilization, and in particular relates to a fruit tree irrigation and fertilization device based on water-fertilizer integration. Background Art

[0002] The water-fertilizer integration technology uses a pressure system or natural elevation difference in terrain to mix soluble solid or liquid fertilizers according to the soil nutrient status and the fertilizer requirements of crops to form a suitable fertilizer solution. This fertilizer solution is mixed with irrigation water, and water and fertilizer are transported synchronously through a precisely controlled pipeline system to ensure that the water and fertilizer are fully integrated. Through pipes and drippers, this mixture is evenly, regularly, and quantitatively supplied to the growth area where the plant roots are located in the form of drip irrigation to promote the healthy development and growth of the plant roots. It is currently used in various fields of agricultural production.

[0003] A Chinese invention patent with authorization announcement number CN111406612B discloses a modern agricultural drip irrigation equipment, specifically relating to the field of agricultural drip irrigation, including a conduit, a flow control and timing mechanism being fixedly installed on one side of the main conduit, a plurality of branch conduits being connected at one end of the main conduit away from the flow control and timing mechanism, a fixing mechanism being fixedly installed at one end of each of the branch conduits, a flow direction mechanism being fixedly installed at the inner cavity of each of the branch conduits through the fixing mechanism, a connecting mechanism being fixedly installed at one end of the flow direction mechanism, and an anti-blocking mechanism being connected to the flow direction mechanism through the connecting mechanism, which relatively reduces the probability of sediment blocking the water outlet of the drip irrigation sprinkler head.

[0004] However, in actual use, once the irrigation system is installed, the fixed position of the device becomes a relatively fixed layout. Generally, the root distribution of crops is relatively concentrated, and the application restrictions are relatively small. However, for fruit trees, as the fruit trees grow and the root system develops, the root area of ​​the fruit trees expands greatly. The original irrigation system outlet may no longer be in the best position and cannot effectively cover the expanded area of ​​the fruit tree root system. If you want to ensure that the fruit trees get uniform and appropriate water and nutrients, you must re-construct and arrange the irrigation system and adjust the position of the outlet. Not only does it require re-investment of manpower and material resources, it may also have a certain impact on the growth of the fruit trees, resulting in a reduction in yield or death of the fruit trees. Therefore, the existing irrigation system has room for improvement in flexibility and adaptability. Summary of the invention
