Abstract

The invention relates to a high-yield method for cultivating land mater convolvulus by lake entering river water floating, belonging to the field of sewage pollution by taking plants as characteristics. The high-yield method has the technical scheme as follows: A. domesticating land mater convolvulus into aquatic mater convolvulus; B. transplanting; C. managing cultivation; and D. harvesting. With a seed seedling culture method, the seed of the land mater convolvulus is sown into the matrix of a floating disk; then, the floating disk is put into a domestication pool, and the land mater convolvulus is domesticated into aquatic mater convolvulus in about 20 days; lake entering river water floating is utilized to cultivate the domesticated mater convolvulus to lower the content of nutrients,such as nitrogen, phosphorus, potassium and the like in lake entering river water, thereby achieving the purpose of treating lake entering river water, and bringing better ecological benefit; and themater convolvulus averagely grows for 2-3cm everyday in summer, yield is big so as to bring a better yield. The high-yield method is used for producing green vegetables or organic vegetables on a large scale, and has better economic benefit.

Description

technical field [0001] The invention relates to the field of sewage treatment characterized by the use of plants, in particular to a method for high-yield cultivation of terrestrial water spinach by floating in lake and river water. Background technique [0002] In the past 30 years, the agricultural production in many lake runoff areas has undergone great changes in crop structure and layout with the adjustment of the planting structure. 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 water movement. There are many main rivers in the lake runoff area, and the nutrients flowing into the main rivers are not on...
