| 中文摘要: |
| 通过中子水分仪定期测定土壤含水量,得出高羊茅草坪土壤中水分的变化规律。结果表明,土壤水分状况分为3层,0~20 cm为活跃层,30~50 cm为次活跃层,50~100 cm为稳定层。草坪能够利用0~50 cm土层的水分,但是不能利用50 cm以下土层的水分。并确定出灌溉深度、灌溉饱和点和灌溉补偿点,为制定合理的草坪灌溉制度提供依据。 |
| 英文摘要: |
| 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. |
