Vertical subsurface irrigation system

Abstract

The invention provides a vertical subsurface irrigation system. The vertical subsurface irrigation system comprises an irrigation container and a supply device, wherein the irrigation container is buried under a furrow and arranged around root systems of crops, a feeding part and a discharging part are arranged at the two ends of the irrigation container respectively, the axis of the discharging part is perpendicular to the ground of the field bed, and the irrigation container is further provided with an internal space communicating with the feeding part and the discharging part; and the supply device is connected to the irrigation container, the supply device conveys nutrients needed by crop growth to the irrigation container, the nutrients enter the inner space from the feeding part and are guided out towards the discharging part, the nutrients permeate to the position under the field bed, the root systems of the crops can grow downwards towards the discharging part, the crops evolve to form plants with the deep root systems, further, the weather stress resistance of the crops is improved, and the purpose of prolonging the growth life is achieved.

Description

technical field [0001] The invention relates to a plant irrigation method, in particular to a vertical underground irrigation system. Background technique [0002] At present, the irrigation method of general traditional agriculture is the flood irrigation method, which is to introduce water directly into the farmland along the ditch or the water pipe, so as to perform flood irrigation on all parts of the field, but the flood irrigation method is the most waste of water resources, and the water in the The flow process is likely to increase the risk of spreading germs, which may cause certain damage to crops in the field. [0003] In order to improve the problems of the above-mentioned flood irrigation method, some related operators have developed the sprinkler irrigation method and the drip irrigation method. Among them, the sprinkler irrigation method is to install water spray equipment in the field and spray water on the surrounding soil or crops. It saves water resources...

Problems solved by technology

[0002] At present, the irrigation method of general traditional agriculture is the flood irrigation method, which is to introduce water directly into the farmland along the ditch or the water pipe, so as to perform flood irrigation on all parts of the field, but the flood irrigation method is the most waste of water resources, and the water in the The flow process is likely to increase the risk of spreading germs and may cause certain damage to crops in the field

[0003] In order to improve the problems of the above-mentioned flood irrigation method, some related operators have developed the sprinkler irrigation method and the drip irrigation method. Among them, the sprinkler irrigation method is to install water spray equipment in the field and spray water on the surrounding soil or crops. It saves water resources and improves irrigation efficiency; however, the sprinkling irrigation method is easily limited by the topography of the field. For example, when the field is an undulating hillside terrain, the sprinkler equipment is easily affected by the topography, and the water cannot be used. Efficiently sprayed to all parts of the field, prone to uneven irrigation, thus unable to meet the nutrient needs of crops

[0004] The drip irrigation method is to distribute the pipeline system in the field. The pipeline system is equipped with drip holes according to the growth position of the crops, and can drip the root growth range of the crops according to the amount of water and nutrients required for the growth of the crops. Therefore, the drip irrigation method It can effectively control the growth needs of crops, and can also improve the efficiency of water use and fertilization; however, the drip irrigation method requires expensive pipeline system laying costs, and it is necessary to balance the drip water pressure in each area of ​​the field, otherwise it will cause uneven irrigation of crops The problem

[0005] please cooperate figure 1 As shown, the aforementioned flood irrigation method, sprinkler irrigation method and drip irrigation method can only irrigate the soil surface layer, causing the crop 1 to effectively absorb the water and nutrients irrigated by the soil surface layer, so that the root system 2 of the crop 1 can only expand toward the surrounding soil surface layer Extending, instead of growing downward to the depths of the soil, crop 1 evolves into a living state with a shallow root system 2, so crop 1 has poor wind resistance and is easily attacked by wind to cause broken branches
