| 摘 要： | 水肥一体化喷灌和滴灌系统耗能高、投资高、对水质要求高，而地面灌溉仍然是大田作物应用的主要灌水技术。针对以上现实，提出田间水肥一体化地面灌溉系统。田间水肥一体化地面灌溉系统由进水管、施肥器、田间输水管和地面灌溉灌水器4部分组成，其中施肥器是无压施肥装置，地面灌溉灌水器是田间分水软管和出水口为一体、在生产过程中一次性成型的地面灌溉灌水设施。田间水肥一体化地面灌溉系统不仅能够实现水肥一体化，且具有低碳环保、灌水效率高、便于与农业机械化相结合的优点，适宜在大田作物生产中大面积推广应用。 |
| 关 键 词： | 农田水利；地面灌溉水肥一体化；灌水器；施肥器 |

| Abstract： | Surface irrigation is still the main irrigation technology application for field crop, however, the fertigation system of sprinkling or drip irrigation system has the defect of high energy consumption, high investment and high water quality requirements. In this paper, based on the above actuality, a surface fertigation system was put forward in crop irrigation. The surface fertigation system was composed of 4 parts: intake pipe, fertilizer applicator, water delivery pipe and surface irrigation watering device. In which, the fertilizer applicator was a kind of pressureless fertilizer applicator suitable for surface irrigation. The surface irrigation watering device was a kind of distributive hose with several water outlets in a fixed spacing, which was linked with water delivery pipe and was used to distribute water to furrow field or irrigation ditch. The surface fertigation system can realize irrigation and fertilization simultaneously, has the advantage of low carbon and high irrigation efficiency, and facilitates with agricultural mechanization. Therefore, the surface fertigation system is worth extensive application in field crop production. |
