Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] The irrigation device of this embodiment can implement local root zone irrigation of water and fertilizer for furrow irrigation crops in the field and greenhouse. Ensure that liquid fertilizer is easy to apply locally and the amount of fertilizer can be adjusted, and ensure that the water output of each outlet pipe is uniform and adjustable, so as to ensure the demand of crops for water and fertilizer and improve the efficiency of water and fertilizer use. The working principle of the water and fertilizer local root zone irrigation method and its irrigation control system is to use a height-adjustable simple water and fertilizer supply device to fertilize, and the c...

Abstract

The invention discloses an irrigation rig, including a support, a main pipeline which is arranged on the support and is used for guiding water into the irrigation rig, a slide bar arranged on the support and a plurality of outlet pipes; one end of the outlet pipe is connected with the main pipeline, the other end thereof is fixed on the slide bar. The irrigation rig has simple principle and is characterized by land saving, water saving, energy saving and fertilizer saving, each part can be quickly disassembled and assembled; furthermore, the irrigation rig has low cost, simple operation and is convenient for extensive generalization and application.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to an irrigation device and an irrigation method suitable for alternate furrow irrigation of local root zones of water and fertilizer for fruit trees, greenhouse furrow irrigation vegetable crops, and field furrow irrigation crops such as corn, cotton, and potatoes. Background technique [0002] Water is the most basic element to maintain plant growth, especially in arid and semi-arid areas, it is particularly important to obtain the maximum irrigation benefits of crops with limited water resources. Based on the principle of water-saving irrigation technology and the root signal theory of crops' perception of water shortage, the root system zoning alternate irrigation technology is to actively control the drying of the soil in the active layer of the crop root system in a certain area of ​​​​the horizontal or vertical section, so that the crop root system always has a part Gro...
