To overcome the"bottleneck" problem concerning water and nutrition in current sand-fixation technology system,we attempted to add slow release fertilizer(SRF) and super absorbent polymer(SAP) to it.On the basis of the compatibility of SRF and invented independently SAP,a pre-designed amount of SAP and SRF were added to cultural system and experiments were carried out for two years in desert-simulating sand to study the effect of this technique on growth and development of licorice.The results showed that different SRF had different effect on water absorbent rate of SAP and various SRF release nutritional elements in simulated sand much more slowly than urea.Adding more or less fertilizer to the technology system could prompt the growth and development of licorice in shoot height,taproot length,development of leaf and biomass(dry weight).The present study put forward a new means to solve the problem of water and nutrition of sand-fixing plant.
