Plant root water injection irrigation system

Abstract

The invention relates to a plant root water injection irrigation system which is characterized by comprising a water supply device and water control valve connected with the water supply device, a main irrigation pipeline connected with the water control valve and paved on the soil and a group of irrigation branch pipelines connected with the main irrigation pipeline. Water injection needles are respectively arranged on the group of irrigation branch pipelines, and the water injection needles are inserted in soil of the roots of plants. Water is injected in the plants through the water injection needles inserted at the positions of the roots of the plants, and the water injection needles are connected to form an irrigation network, and a water-saving efficient irrigation technique is achieved. Soluble fertilizer can be blended in the device in an irrigation process so as to achieve irrigation and fertilizing integration. The plant root water injection irrigation system is high in automation, simple to use, convenient to manage, capable of being reused and favorable for water and fertilizer absorption of the plants through an irrigation method for injecting water and fertilizing at the roots of the plants directly.

Description

technical field [0001] The invention belongs to the technical field of plant irrigation, in particular to a plant root water injection irrigation system. Background technique [0002] Currently known irrigation methods in the world include technologies such as flood irrigation, sprinkler irrigation, drip irrigation, and infiltration irrigation. Among them, although flood irrigation, sprinkler irrigation and drip irrigation are used in different ways, they are all ground irrigation methods, which absorb water from the ground to the roots of plants, and about two-thirds of water resources are wasted. Similarly, the water-fertilizer integration technology using these methods cannot make the plant roots fully absorb the fertilizer, resulting in a waste of fertilizer. In addition, if the common ground irrigation technology is used in an indoor environment (such as a greenhouse), it will lead to an increase in the humidity of the indoor environment, which will lead to aggravated ...

AI Technical Summary

Problems solved by technology

[0003] There is also an underground infiltration irrigation technology in the irrigation industry, that is, drip irrigation equipment is buried under the soil of the roots of the plants, and water is slowly sent to the ground to achieve the effect of root irrigation and fertilization, but this technology requires a lot of labor to dig ditches and install the equipment. It is buried underground and difficult to recycle. It is not suitable for the application of agricultural machinery in the field. It is a one-time use and is easy to block, which is not conducive to large-scale promotion
