Problems solved by technology

[0005] At present, the transplanted aquatic plants used in the treatment of water body eutrophication to control water blooms are mainly water hyacinth and aquatic plants, but water hyacinth is difficult to control because of its rapid reproduction, low utilization value and basically no economic benefits
Although other treatment methods can achieve certain ecological benefits, the investment is large and there is basically no economic benefit

Abstract

The invention relates to a method for culturing mentha canadensis by using floating of lake inflowing river water, and belongs to the field of sewage treatment using plants as characteristics. According to the technical scheme, the method comprises the following steps of: A, domesticating mentha canadensis seedlings into aquatic seedlings; B, transplanting; C, culturing and managing; and D, harvesting. According to the method, the growing environment of the mentha canadensis is changed, the mentha canadensis cuttage seedlings are inserted into the medium of a floating tray by adopting a cuttage method, the floating tray is put into a domestication pool for domesticating, the terrestrial seedlings can be domesticated into the aquatic seedlings in about 20 days, and the mentha canadensis iscultured by using floating of the lake inflowing river water, so that the content of nutrients such as nitrogen, phosphorus, potassium and the like in the lake inflowing river water can be reduced, the purpose of treating the lake inflowing river water is fulfilled, and the method has relatively good ecological benefit; and the mentha canadensis is grown fast in summer, so relatively high yield is realized and higher return rate can be brought; and the method is used for producing green vegetables or organic vegetables in large scale, and has relatively good economic benefit.

Description

technical field [0001] The invention relates to the field of sewage treatment characterized by utilizing plants, in particular to a method for cultivating mint by floating into lakes and rivers. Background technique [0002] In the past 30 years, agricultural production in many lake runoff areas has undergone great changes in crop structure and layout with the adjustment of planting structure. The sown area of ​​grain crops has decreased and the area of ​​vegetables has increased rapidly, which has effectively promoted the development of regional rural economy. Rapid development. Compared with food crops, vegetables require a large amount of fertilizer, and the multiple cropping index is high, which will greatly increase the amount of fertilizer applied per unit of land area per unit of time, coupled with unreasonable fertilization by farmers, The soil nutrient structure is unbalanced, the residual nutrient increases, and it is easy to flow into the river (ditch) with the w...
