Description
技术领域technical field
本实用新型涉及滴灌领域，具体领域为一种环保滴灌装置。The utility model relates to the field of drip irrigation, in particular to an environment-friendly drip irrigation device.
背景技术Background technique
滴灌是按照作物需水要求，通过管道系统与安装在毛管上的灌水器，将水和作物需要的水分和养分一滴一滴，均匀而又缓慢地滴入作物根区土壤中的灌水方法。滴灌不破坏土壤结构，土壤内部水、肥、气、热经常保持适宜于作物生长的良好状况，蒸发损失小，不产生地面径流，几乎没有深层渗漏，是一种省水的灌水方式。滴灌的主要特点是灌水量小，灌水器每小时流量为2-12升，因此，一次灌水延续时间较长，灌水的周期短，可以做到小水勤灌；需要的工作压力低，能够较准确地控制灌水量，可减少无效的棵间蒸发，不会造成水的浪费；滴灌还能自动化管理。Drip irrigation is an irrigation method that drips the water and the moisture and nutrients required by the crops into the soil in the root zone of the crops evenly and slowly through the piping system and the irrigator installed on the capillary tube according to the water requirements of the crops. Drip irrigation does not damage the soil structure, and the water, fertilizer, air, and heat inside the soil are always kept in a good condition suitable for crop growth. The evaporation loss is small, there is no ground runoff, and there is almost no deep leakage. It is a water-saving irrigation method. The main feature of drip irrigation is that the amount of irrigation water is small, and the flow rate of the emitter is 2-12 liters per hour. Therefore, the duration of one irrigation is longer and the cycle of irrigation is shorter, which can achieve frequent irrigation with small water; the required working pressure is low, and it can be more Accurately controlling the amount of irrigation water can reduce ineffective evaporation between trees and will not cause water waste; drip irrigation can also be managed automatically.
现有的滴灌水源采用一般采用地下水或者河水，由于地下水或者河水都或多或少的含有泥沙，从而导致需要大量的净化设备，这样造成了额外的电力损耗。The existing drip irrigation water sources generally use groundwater or river water. Since the groundwater or river water contains more or less sediment, a large amount of purification equipment is required, which causes additional power loss.
