| Abstract: |
| he dynamics of soil water content of tall fescue turf has been studied with neutron probe.The results showed that the soil water profile in 0～100 cm could be divided into 3 layers,i.e.,active layer (0～30 cm),hypoactive layer(30～50 cm) and relatively stable layer(50～100 cm). The turf grass could utilize soil water in 0～50 cm depth,but could not utilize that below 50 cm.The paper also proposed the reasonable irrigation depth,irrigation saturation point and irrigation compensation point,which might provide theoretic basis to make out irrigation scheme of turf grass. |
