Other Abstract
In order to meet the irrigation requirements of different landscape plants in vertical greeningan automatic vertical greening device
based on porous filter material is designed. The device realizes the change of soil water potential from negative pressure to positive pressure
through Porous absorbent filter material by using the principle of soil water balanceso that the soil water potential is maintained at different
pressure valuesthereby creating different soil moisture environments to meet the water requirements of various landscape plants. And through
the coupling relationship between soil moisture content and soil matrix potentialthe discharge flow of emitters is adjusted to achieve
automatic irrigation for different landscape plants in vertical greening. In order to determine the parameters of the devicethe water tank
heightsoil depthwater-absorbing wire material and diameterand porous ceramic emitter material ratio are taken as the parameters to be
determined. Through the theoretical calculation of water demand for landscape plant irrigationthe analysis of the impact test of different wire
materials and diameters on soil water absorption and water content and the ratio optimization of porous ceramic emitterthe parameters are
determined. Through the benefit analysis comparisonthe cost of the device is reduced by 50% ~ 70% compared with the existing vertical
greening device.
