Abstract

The invention relates to an ecological water and fertilizer supply system for lawns in arid and semi-arid areas, which comprises a water and fertilizer supply pipeline system, wherein the water and fertilizer supply pipeline system is composed of a plurality of water and fertilizer supply units, each water and fertilizer supply unit comprises a water inlet pipe, a plurality of irrigation pipes and a water outlet pipe, a plurality of openings which are used for drip irrigation are formed along the length direction of the irrigation pipes, and a drip irrigation emitter is arranged on each water inlet tube. The ecological water and fertilizer supply system is characterized in that each drip irrigation emitter with two effects of spraying and dripping comprises a water inlet cavity, a first water outlet cavity, a second water outlet cavity and a flow control valve core, wherein each flow control valve core is provided with a top part, a middle part and a base, each base is in a shape of a circular disc, and the diameter of each base is greater than that of a water outlet of the related first water outlet cavity; a connecting part used for containing each base is arranged in a water inlet of the related first water outlet cavity in the related drip irrigation emitter, and the diameter of each connecting part is greater than that of the related base; and a plurality of grooves are formed in the bottom surface of each base and the surfaces, which correspond to the bases, of the connecting parts, and elastic bodies are arranged in the grooves. The ecological water and fertilizer supply system has the advantages of simple structure, low cost, convenience in use and the like.

Description

technical field [0001] The invention relates to a lawn irrigation system, in particular to a lawn ecological water and fertilizer supply system suitable for arid and semi-arid areas, and belongs to the technical field of garden engineering. Background technique [0002] Lawns play an important role in the process of modern urban greening. They can beautify the environment, adjust the microclimate, prevent noise, purify the atmosphere, and maintain water and soil. At the same time, they can also be used as sports fields and competition fields. The importance of lawns has been increasingly recognized by the world know. The amount of lawn area per capita is one of the important indicators for measuring modern cities in the world. In the vast northwestern region where the economy of our country is relatively lagging behind, lawn construction has also developed rapidly with the opportunity of the western development. In these relatively dry and rainless towns, people have put i...
