Abstract
Description
technical field
[0001] The invention relates to a method for planting vegetables, in particular to a method for floating and planting vegetables in eutrophic water bodies. Background technique
[0002] Eutrophication of water body is a global water environment problem. According to reports, more than 90% of China's lakes are becoming eutrophic, and the degree of eutrophication in lakes around cities is the most serious. Since the 1970s, countries all over the world have carried out research on the comprehensive treatment technology of eutrophic lakes, and biological treatment is an important part of comprehensive treatment. The use of biological floating beds to control eutrophic water bodies is gradually becoming a key technology for the restoration of damaged aquatic ecosystems. The research and application of floating bed systems in China is increasing, and the types of plants have also developed from rice, ryegrass and cress to vetiver and canna. , water spinach and ot...
Examples
Embodiment Construction
[0048] (1) Select water area
[0049] The waters around Dianchi Lake in Kunming are selected as the floating vegetable planting area, fresh water slow-flowing waters, and the bottom is flat; 100 acres are surrounded by dams, with water inlets at one end and water outlets at the other end.
[0050] (2) Detect the components contained in the water quality in the vegetable planting area:
[0051] Nitrogen≥0.5mg / L, phosphorus≥0.05mg / L, potassium≥0.5mg / L
[0052] PH value=6-8
[0053] Arsenic and its compounds (calculated as As) ≤0.01mg / L
[0054] Cadmium and its compounds (calculated as Cd) ≤0.005mg / L
[0055] Lead and its compounds (calculated as Pb) ≤0.01mg / L
[0056] Chromium and its compounds (calculated as Cr)≤0.05mg / L
[0057] Mercury and its compounds (calculated as Hg) ≤0.001mg / L
[0058] And does not contain: Potassium ammonium phosphate, 666, Didi ladder and other pesticides.
[0059] (3) Organize the vegetable planting area
