Abstract

The invention relates to a method for biologically enriching and recycling urban water body copper ions. Riverway copper ions are enriched by using salvinia natans and used for preventing and controlling downy mildew of seedlings raised in a greenhouse. The method is characterized by sequentially comprising the steps that the salvinia natans is cultivated; the salvinia natans is put in a riverway needed to be treated; an enclosure device is added in the riverway, and the salvinia natans is put in the device; growing salvinia natans is salvaged, removed and changed; the salvaged salvinia natans is smashed and roll-compacted to obtain and store salvinia natans juice; the salvinia natans juice is utilized to prepare a downy mildew resisting agent. The salvinia natans has very strong heavy metal copper enriching capability. In addition, the downy mildew resisting agent prepared by the salvinia natans juice can be also utilized.

Description

technical field [0001] The invention relates to a method based on the biological enrichment and recycling of copper ions in urban water bodies, and the enrichment of copper ions in river channels by using acacia japonica and used for the prevention and treatment of downy mildew in greenhouse seedling cultivation. Background technique [0002] With the rapid development of the social economy and the continuous accumulation of people's wealth, the people have put forward higher requirements for the living environment. "Bluer sky, clearer water, and more beautiful scenery" has become the direction of local governments' efforts. In recent years, the country has invested a lot of money in the comprehensive management of urban rivers; various related enterprises are also investing huge manpower and material resources in the comprehensive management of water quality. However, it has been found that most of the relevant enterprises control the frequent and highly active blue-green a...
