【摘要】 根据金鱼藻根严重退化的特殊性,用几种栽培方式探讨将其置于类似网箱养鱼的网箱中,或散养,或适当固定,并借助网箱养鱼的沉子、浮子,使其可在水层中上下移动,利用沉水植物光合放氧增加水体中溶解氧,吸收N、P等净化富营养化水体的可能性。更多还原

【Abstract】 The foot of the hornwort has the property of deterioration, and the hornwort is put in the box with net to be planted by several ways of free planting or stable planting, at the same time they can be moved up and down in the water using fishing float. The movement of hornwort in water can increase the content of dissolved oxygen of water, the results of the experiment study the possibility of the absorption of N and P by the hornwort to purify the water body.更多还原
