利用人工栽培方法，研究了武汉东湖重污染区湖水和底泥对黄丝草（ＰｏｔａｍｏｇｅｔｏｎｍａａｃｋｉａｎｕｓＡ．Ｂｅｎｎ．）生长的影响。以湖滨黄棕色粘土作对照，在上覆水条件相同时，东湖底泥上培养的黄丝草生长良好，生物量高，枝条较长。东湖底泥中黄丝草根系较纤细，每个植株的根数也较少，但根系活力明显高于对照。底泥中有机质过高对黄丝草根系发育不利。东湖湖水的水质状况对黄丝草的生长也有一定的影响，在底质相同的情况下，在湖水中生长的黄丝草生物量低，根茎重量比小，根数少。对东湖黄丝草种群消失机理和水生植被重建对策也作了探讨。
The effects of lake water and sediment on the growth of Potamogeton maackianusA. Benn. Were studied using artificial cultivation methods. Yellow lake brown lake as a control, the same conditions in the overlying water, the East Lake sediment grown on the yellow grass growth, biomass, branches longer. In the sediment of East Lake, the roots of Xanthium sibiricum are slender and the root number of each plant is less, but the root activity is obviously higher than that of the control. The high organic matter in the sediment adversely affected the root development of Xylene yellow. The water quality of Lake East Lake also has a certain impact on the growth of Xylene Grass. Under the same substrate, the biomass of Xanthium sibirica which grows in the lake is low, the weight ratio of rhizome is small and the number of roots is small. The mechanism of the disappearance of E. grandis population and the reconstruction of aquatic vegetation were also discussed.
