摘要
针对我国设施农业的发展和需求现状,研制了一套施肥量可调、能够在不同温室内自由移动的精准施肥机。通过实验和推广应用表明,该机性能优异,灌水、施肥的均匀度分别达99.6%和98.8%,具有操作简单、节水、肥料利用率高和节约劳动力成本等显著特点。同时,该机能够实现滴灌施肥和叶面肥喷洒两种施肥方式。
In view of the present situation of the development and the demand for our country facility agriculture, an aqua fertilizer applicator were developed, which can apply fertilizer precisely and can move freely in different greenhouses. The experiment and application test showed that this machine performance is outstanding, the uniformity of irrigation and fertilizer application reach to 99.6% and 98.8% respectively, and it operates simple. There are many advantages such as saving water, high fertilizer utilization and saving labor cost and so on. Moreover, this machine can realize two kinds of fertilizer applications which are fertigation and leaf surface fertilization.
