摘要:
迄今为止,在北方冬季冰下仅发现有菹草、聚草、黄丝草、金鱼藻及扇叶水毛莨等几种水生维管束植物存活,其生物量力10-3500g/m2,依其单位面积鲜重大小顺次为菹草、聚草、黄丝草、金鱼藻、扇叶水毛莨。明暗瓶试验结果表明冰下各水草光台毛产氧量变动于0.039-3.610mg O2/d·g(草)之间,以菹草产氧量最大,其后顺次为扇叶水毛莨、聚草、金鱼藻。

Study on the under-ice fibro-vascular plants in some water bodies in three northern provinces of china
Liu Guocai
Abstract:
The under-ice fibro-vascular plants have been observed to be survival in the winter beneath some water bodies in three northern provinces of China (Jiling, Liaoning and Inner Mongonia), including Potamogeton crispus, Mpriopyllum spicalum, Potemogelon maeckianus, Ceratophyllum detnersum, Bairackium bungei etc.The biomass of these plants varies from 10 to 3500 g/m2,while their fresh weights in a unit area are in such order as Potflmoyeton cripus, Myriophyllum spicaium, Polamogeion maackianus, Ceratophyllum detnersum and Batrachium bungei. According to the outcomes of black-white bottle tests, the amount of oxygen produced by these plants through photosynthesis fluctuates between 0.039 and 3.610 mg O2/d·g (plant), in which the Polamageton crispus gives the biggest, others are Batrachtum bungei, Myriophyltum spicatum, Ceratophyllum demersum accordingly.
