| 摘 要： | 1989年3—10月对江苏滨海废黄河口互花米草初级生产的测定为总生物量(干重)净增3154.8gm~(-2)·a~(-1)。对盐沼中Fe、Cu、Mn、Zn的动态研究表明,Fe、Mn的年变化与互花米草的生物量变化较趋一致,7—8月份Fe、Mn的供应不足也许是米草生长的限制因子;9月的Zn峰可能与生殖生长有关;至于7月的Cu峰是否与强化呼吸有关,还值得探讨。对高生产力的互花米草盐沼资源应予以重视,本文提出了有关开发利用的构想。

| Abstract: | The total biomass of S.alterni flora growing in the mouth of the old yellow river course in Binhai county, Jiangsu province, was 3154.8g(dw)/m2-a in 1989.The annual changes in Fe and Mn.were similar to the biornass change of S.alterniflora,and parhaps the lack of Fe and Mn in July and August was the limitation of Spartina growing.The highest value of Zn in September was probably correlated with the plant reproduction.It is well worth to enquire whether the highest value of Cu in July is correlative or not with intensifying respiration.Much attention should be paid to salt marsh of Spartina with higher productivity and some suggestion was made on the development and utilization of this plant. |
