Automatic irrigation device applied to orchard

Abstract

The invention discloses an automatic irrigation device applied to an orchard. The automatic irrigation device comprises a transmission unit, a detection unit, a measuring unit, a control unit and water supplying units. The multiple water supplying units are connected with a sprinkling irrigation head and a dropping arrow which are arranged on a middle standing rod through a first sprinkling-irrigation main pipe electromagnetic valve, the sprinkling irrigation head and the dropping arrow are connected with a flow meter, the middle standing rod is fixed on one side of a fruit tree, the sprinkling irrigation head is arranged at the upper end of the middle standing rod, automatic irrigation and fertilization of the orchard are achieved, the automatic irrigation device is suitable for accurate and intelligent orchard management of citrus trees with the large areas and the different heights, the yield and the quality of the orchard are greatly improved, and the income of fruit farmers are increased.

Description

technical field [0001] The invention relates to an agricultural irrigation device, in particular to an automatic irrigation device applied to orchards. Background technique [0002] Irrigation and fertilization are two important links in orchard production and management, which directly affect the yield and quality of citrus. The southern Jiangxi region where citrus is grown has uneven rainfall throughout the year, and summer is dry and rainless, and summer is the growth and reproduction period of citrus. Sufficient irrigation during this period is a key period to improve the yield and quality of citrus. [0003] In winter, freezing rain is often encountered, and the leaves are in the state of ice for several days in a row. The fruit trees cannot withstand this extreme cold state, and they are prone to freezing to death and frostbite, which directly affects the quantity of citrus in the coming year, or even directly zero output in the next year, bringing destruction to the c...

Problems solved by technology

[0005] At present, the domestic water and fertilizer integration system has not been industrialized, and there are many defects. For example, it can only carry out artificial water and fertilizer ratio, and the power cannot meet the irrigation, fertilization, and antifreeze requirements of the orchard area, or even irrigation, fertilization, and antifreeze at the same time. , monitoring and other five functions; the freezing rain in winter lasts for several days, and what is needed is large-area, high-power, uninterrupted sprinkler irrigation and anti-freezing. This is a problem that previous studies on the integration of water and fertilizer have not considered; In terms of function, the integration does not realize remote control, does not use environmental monitoring data as a reference, cannot plan fertilization, irrigation, antifreeze, waste water and fertilizer resources, and the controller does not add algorithms for predictive irrigation to achieve the purpose of precise and precise irrigation. Did not bring water and fertilizer integration technology into the Internet era of precision agriculture
