注肥器可以用来向灌溉水溶液中定量注入液态化学肥料、防治土壤病害的化学农药、植物生长调节剂以及植物生长所需的多种微量元素。近年来,温室注肥器在发达国家得到了广泛的推广应用。在我国,随着设施种植面积的逐年扩大,温室注肥器也得到大量的推广应用。由于多数先进的注肥设施都是从国外引进的,成本较高,在使用过程中的维护保养不当,极易造成使用效率低下,易出现故障。本文试图对其相关的使用及维护保养进行简单的介绍,以供设施种植者提高使用效率,减少使用过程中发生故障的情况。 Injectors can be used to quantitatively inject liquid chemical fertilizers into irrigation water solutions, chemical pesticides to combat soil diseases, plant growth regulators, and trace elements for plant growth. In recent years, greenhouse fertilizers have been widely used in developed countries. In our country, with the expansion of facility planting area year by year, a large number of greenhouse fertilizers have also been popularized and applied. As most of the advanced fertilizer facilities are imported from abroad, the higher the cost, improper maintenance in the process of using, can easily lead to the use of low efficiency, prone to failure. This article attempts to provide a brief introduction of its related use and maintenance for plant growers to improve their efficiency and reduce the occurrence of malfunctions during use.
