A paddy field irrigation system

Abstract

The invention relates to the field of agriculture, in particular to an irrigation system for a paddy field. The system comprises a supporting structure, filtering structures, diversion holes, a waterlevel adjusting structure, a fixing structure and a driving structure; the rectangular diversion holes for drainage are formed in the supporting structure, and filtering structures which are used forfiltering sludge and correspond to the diversion holes one to one are arranged on the side wall of the supporting structure; the water level adjusting structure which cooperates with the diversion holes to adjust the water level of the field is arranged inside the supporting structure; the fixing structure used for preventing soil from collapsing is arranged at the top of the supporting structure,and provided with the driving structure used for cleaning the diversion holes and dispelling birds. According to the irrigation system, through the cooperative use of the supporting structure and thefiltering structures, the soil loss is effectively prevented in the irrigation and drainage process, and the sludge in the diversion holes is removed under the push of wind force; meanwhile, the system also has the function of dispelling the birds, the water level adjusting structure is arranged inside the supporting structure, and the water level of the field is conveniently adjusted in different periods, so that irrigation is more convenient and flexible.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a paddy field irrigation system. Background technique [0002] Technical measures to supplement the water required by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, it cannot meet the needs of crops for moisture. Requirements, artificial irrigation must be carried out to make up for the lack of natural rainfall. Irrigation, that is, watering the land, the principle of irrigation is that the amount of irrigation, the frequency of irrigation and the time should be determined according to the water demand characteristics of medicinal plants, growth stages, climate, and soil conditions. , to timely, appropriate, and rational irrigation, in the process of rice planting, it is necessary to reasonably control the amoun...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional paddy field irrigation system is easy to cause blockage of the drainage pipe in the process of using pipeline drainage in the field, and it is easy to cause soil loss when the method of excavating the drainage outlet is used for drainage and irrigation, which is inconvenient for the control of the water level in the field
