Ground source integrated trickle irrigation system

Abstract

The invention belongs to the technical field of the development and utilization of water and land resources and relates to a ground source integrated trickle irrigation system. The system comprises a planting pit dug in a dry area; the bottom and sidewall of the planting pit is provided with a seepage cutoff film layer; the planting pit is sequentially filled with a fine sand layer and a cultivated soil layer; a ridge is arranged around the cultivated soil layer; a water collection ditch is arranged at the bottom of the fine sand layer; the water collection ditch is communicated with a water collection well arranged in the planting pit; a water pump and a water outgoing pipe I connected with the water pump are arranged in the water collection well; the water outgoing pipe I is connected with a low pressure network in the cultivated soil layer through a pipeline; a moisture sensor is disposed in the cultivated soil layer; the water pump and the moisture sensor are connected with a control module disposed on one side of the ridge; the control module is connected with a user computer. The ground source integrated trickle irrigation system is simple in structure and reasonable in design, the dry cultivated layer is used for collecting natural rain, the natural rain stored in pores of the fan sand layer is used as an irrigation water source, the dry land and the water source are organically combined, and the normal growth of crops is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of development and utilization of water and soil resources, and in particular relates to a ground-source integrated sprinkler irrigation system. Background technique [0002] As we all know, food production is guaranteed by the irrigation system. Since the founding of New China, my country has increased the effective irrigated area from 239 million mu at the beginning of liberation to 905 million mu by implementing projects such as continued construction of large-scale irrigation areas and water-saving renovations. Places with abundant water resources have basically been solved, laying a solid foundation for my country's "nine consecutive increases" in grain. However, there are still nearly half of the land area that cannot be effectively irrigated. The main reason is the shortage of water resources and the lack of supporting water conservancy infrastructure. "Looking forward to harvesting" cultivated land ha...

However, there are still nearly half of the land area that cannot be effectively irrigated. The main reason is the shortage of water resources and the lack of supporting water conservancy infrastructure. "Looking forward to harvesting" cultivated land has seriously hindered the development of my country's agricultural production, ecological security and national economy
