An underground layered irrigation system integrating fertilizer and water

Abstract

The present invention discloses a fertilizer-water integrated underground layering irrigation system, which comprises a fertilizer preparing stirring device, a liquid storage pool, a water storage device and an underground layering irrigation device, wherein the fertilizer preparing stirring device and the water storage device are communicated to the liquid storage pool respectively through pipelines, the liquid storage pool is communicated to the underground layering irrigation device, and the underground layering irrigation device is arranged under the soil layer. With the system of the present invention, the waste of the fertilizer during the fertilizer application process can be avoided, the fertilizer application amount can be effectively reduced, the characteristics of high fertilizer application efficiency and uniform fertilizer application are provided, the quantitative irrigation on crops can be achieved, the irrigation belongs to the underground irrigation, the water loss during the irrigation process is effectively reduced, the controllability is good, the requirements of different crops and plants at different growth stages on water can be met, and the effects of water saving and crop growth promotion are achieved.

Description

Technical field [0001] The invention relates to a fertilizer-water integrated underground stratified irrigation system, belonging to the technical field of water-saving irrigation. Background technique [0002] For a long time, my country’s crop irrigation methods have mainly used surface irrigation methods such as flood irrigation, furrow irrigation, and sprinkler irrigation. Irrigation water penetrates from the ground to the roots of crops, and the roots of crops absorb water and fertilizer to meet their own growth and development. However, these irrigation methods cause More than half of the water and fertilizer was wasted. However, crop roots are irrigated in layers, and water and fertilizer are directly irrigated to crop roots, which reduces water loss and fertilizer waste, and can increase water and fertilizer utilization. At present, the existing infiltration irrigation technology bury the drip irrigation belt under the soil and slowly convey water to the ground, but the e...

AI Technical Summary

Problems solved by technology

One of the root layer irrigation devices is mainly divided into upper and lower layers, with a fixed distance between layers, which is only suitable for underground irrigation of some crops; the plant root water injection irrigation system uses the root water injection needle inserted into the plant root soil, and the water injection needle The requirements are relatively high, and it is easy to be damaged by hard stones when inserted into the soil; a corn fertilizer and water integrated drip irrigation device is only suitable for the planting of corn to realize the integration of fertilizer and water in the corn field, which has limitations on crops and is not widely applicable. , cannot be used on a large scale

Among the devices and systems mentioned above, there is no underground layered irrigation system that can realize the integration of fertilizer and water, and there is no device and system for layered irrigation according to the different growth periods of crops.
