【摘要】 水松(Glyptostrobus pensilis K.Koch.)是华南平原水网地区为数不多的珍贵针叶用材树种和优良防护林树种之一,亦是我国特有的孑遗植物,具有重要的经济价值和科学研究的意义。广东省现保存的最老水松之一,树龄约500年,树高达40.5米,胸径110厘米。 水松性喜水湿,为强阳性树种,具有一定的耐寒力,适生于中性或偏微碱性或酸性土壤,有着相当的抗盐性,幼苗或幼树在含盐量0.28％时显现粗壮,生势良好。 在适宜的生境条件下水松10年生以前生长快速,上下均匀,尖削度小,生物产量高,20年后可达木材的工艺成熟期。 本文在调查研究的基础上,特别对水松的生态特性与栽培技术特点的相关性进行了分析探讨。种植点位置的确定,取决于地下水位的高低,成为影响水松生产力状况的重要一环。当水松种植于潮水线上15—30厘米范围时,其生长量较其余种植点位置(潮水线上下60厘米)要高1—2倍,甚至更多,说明栽培技术的精细性对水松生产潜力的巨大作用。更多还原

【Abstract】 Glyptostrobus pensilis K.Koch is one of the famous’ living fossil’ species in China. It is a good species for shelter belt and valuable timber tree. The oldest living specimen in the province of Guangdong reaches a height of 40.5m with 110cm in diameter.Under suitable conditions this Chinese species of semideciduous "water pine" grows at a rapid rate and evenly during the first ten years. It is fairly resistant to salt, wnen they are young they can tolerate up to 0.28% of salinity in, they are short the soil and under such condition. They can still grow well and strong. The rise and fall of submerging or underground water level considerably affect the productiveness of this species.更多还原
