Problems solved by technology
[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the irrigation uniformity of the circular sprinkler under the fixed height of the nozzle from the ground can only be guaranteed through the existing nozzle configuration method, but in practice During the irrigation process, the height of the sprinkler head needs to be determined according to the height of the crop canopy, which leads to the fact that the irrigation uniformity of the sprinkler head configured by the existing sprinkler head configuration method cannot meet the requirements in actual irrigation

Embodiment Construction
[0047] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art.
[0048] When the circular sprinkler is running, the main water pipe rotates around the center point, and the water flow is transported through the main water pipe to the drooping pipes connected to the main water pipe, and then sprayed out through the nozzles connected to the drooping pipes to irrigate the crops . Water distribution characteristics are an important indicator of sprinkler performance and an important factor affecting irrigation uniformity. Different types of nozzles have different water distribution characteristics at different installation heights. In the circular spri...

The invention discloses a configuration method for sprinkler heads of a circular sprinkling irrigation machine and an irrigation method, and belongs to the technical field of irrigation, wherein the configuration method for the sprinkler heads comprises the following steps: obtaining target canopy heights of the sprinkler heads of different types in the growth process of target crops as water distribution characteristics while being taken as installation heights, wherein the installation heights are the heights from the sprinkler heads to the ground; establishing a sprinkler head system suitable for the target canopy heights in the growth process of the target crops according to the target canopy heights of the sprinkler heads of different types in the growth process of the target crops as the water distribution characteristics while being taken as the installation heights. The sprinkler head system established through the configuration method is used, so that the uniformity of irrigation can be effectively guaranteed, furthermore, the utilization ratio of irrigation water can be improved.
Description
technical field [0001] The invention relates to the technical field of irrigation, in particular to a nozzle configuration method and an irrigation method of a circular sprinkler irrigation machine. Background technique [0002] The circular sprinkler, also known as the central pivot sprinkler, has the advantages of high degree of automation and wide application range, and has been widely used in agricultural irrigation. The circular sprinkling irrigation machine comprises a main water delivery pipe, on which a plurality of drooping pipes are installed, and a counterweight pipe and a sprinkler are installed at the lower end of each drooping pipe. When the circular sprinkler is running, the main water delivery pipe rotates around the center point, and the water flow is delivered to each drooping pipe through the main water delivery pipe, and then sprayed out by the nozzle to irrigate the crops. Since the running track of the circular sprinkler is circular, in order to ensure...
