Description

Technical Field

[0001] The invention relates to the technical field of integrated water-fertilizer irrigation for crops, in particular to an integrated water-fertilizer irrigation system for crops. Background Art

[0002] Water-fertilizer integration technology refers to a new agricultural technology that integrates irrigation and fertilization. Water-fertilizer integration uses a pressure irrigation system to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types. The fertilizer solution is mixed with irrigation water to evenly infiltrate the crop root development and growth area, so that the main root soil always remains loose and has an appropriate water content. At the same time, according to the fertilizer requirements of different crops, soil environment and nutrient content, the water requirements of crops in different growth periods, and the fertilizer requirements, the demand design for different growth periods is carried out, and water is directly provided to crops in proportion;

[0003] The existing integrated water-fertilizer irrigation system is mostly an independent irrigation system for irrigating crops in the field, which is composed of a pressure unit, a water-fertilizer mixing unit, a drip irrigation unit, etc. The pressure unit is fixedly installed near the field, and the water and fertilizer are mixed in a certain proportion by the water-fertilizer mixing unit and then transferred to the drip irrigation unit through the pressure unit. The drip irrigation unit is generally composed of a drip irrigation pipe or a drip irrigation belt. The drip irrigation pipe or the drip irrigation belt is mostly arranged near the roots and stems of crops in the field to realize the integrated water-fertilizer irrigation of crops. Although the integrated water-fertilizer irrigation system in the prior art has the advantages of fast fertilizer effect of irrigation and fertilization, improved nutrient utilization rate, and can avoid the volatilization easily caused by the application of fertilizers in the drier surface soil layer during water-fertilizer irrigation, The problem of loss, slow dissolution and slow fertilizer effect is solved. However, the following problems still exist in actual use: since the drip part is set on the ground in the field, other external equipment cannot be used to loosen the soil, weed and break the roots in the field. If the time is too long, it will cause soil compaction, affect the root development of crops, and affect the quality of crops. Long-term implementation of water-fertilizer integration is likely to cause long-term over-wetting in the root zone, causing root suffocation. The application of large amounts of water-soluble fertilizers also has the risk of secondary salinization. Moreover, the one-time investment of water-fertilizer integration is relatively large and the flexibility is poor. It is not suitable for use in planting areas with small planting scales or multiple planting areas that are relatively far apart.

[0004] The existing Chinese patent publication number (CN115152398B) discloses a water-fertilizer integrated irrigation device, including an irrigation carrying frame, an integrated mixing mechanism, an irrigation liquid supply mechanism, a pesticide spraying mechanism, and an irrigation spraying mechanism. A three-point suspension frame is fixedly installed on the irrigation carrying frame, and the three-point suspension frame is located on one side of the irrigation carrying frame. When irrigating crops in the field, the present invention is not only convenient for irrigating the crops in the field after the water and fertilizer are integrated, but also when irrigating the crops, it is easy to spray pesticides on the branches and leaves of the crops according to the height of the crops, thereby increasing its functionality. Compared with the water-fertilizer integrated irrigation system in the prior art, it has lower cost and higher flexibility, and is suitable for use in planting areas with small planting scales or multiple planting areas with relatively far distances within the planting area.

[0005] However, the driving equipment is bulky, inconvenient to turn around and will produce many tire marks, which will inevitably damage crops. The equipment consumes a lot of energy and is inconvenient to work in mountains, hills, terraces and other landforms.
