Embodiment 1

[0021] A method for planting seawater vegetables in tidal flat sea prawn culture wastewater, comprising the waste water produced by conventional sea prawn culture on the tidal flat, is characterized in that it includes the following steps:

[0022] (1) Select plots next to the shrimp ponds where sea prawns are cultured in seawater, plow the soil deeply, remove weeds, make furrows on flat ground, with a furrow width of 3m, and make furrows between furrows with a width of 25cm and a depth of 25cm, and a furrow around the field with a width of 45cm. Groove depth 25cm;

[0023] (2) In April, the border was flooded with sea shrimp culture wastewater for 3 consecutive days, and the wastewater was discharged after staying for 2 hours each time; on the 4th day, 1.8 kg of seeds were used per mu, spread evenly, and covered with 1.5 kg of seeds on the surface of the border after sowing. cm of fine sand; after the seedlings grow, use the cultured sea prawn wastewater to irrigate every day...

Abstract

The invention relates to a method for planting sea vegetables by using sea shrimp farming wastewater in a tidal-flat region. The method makes use of wastewater generated in conventional seawater shrimp farming in the tidal-flat region. The method includes the following steps that 1, a land is selected near a shrimp pond used for seawater sea shrimp farming, the land is deeply ploughed, weeds are removed, and soil preparation and bedding are conducted; 2, in April, flood irrigation of the sea shrimp farming wastewater is conducted on beds, sowing is conducted, and the sea shrimp farming wastewater is used for irrigation; 3, in May and June, flood irrigation of the wastewater is conducted on a trench between each two adjacent beds; 4, in July and August, flood irrigation of the wastewater is conducted on the trench between each two adjacent beds; 5, in September, flood irrigation of the wastewater is conducted on the trench between each two adjacent beds; 6, in October and November, harvesting is conducted. The method for planting sea vegetables by using sea shrimp farming wastewater in the tidal-flat region is provided, the wastewater generated by the shrimp pond built in the tidal-flat region for conventional seawater shrimp farming is made use of, the utilization rate of wastewater is improved, green treatment is achieved, operation is feasible, and the cost is low.

Description

technical field [0001] The invention belongs to the field of planting, and relates to a method for planting seawater vegetables with tidal flat sea shrimp culture wastewater. Background technique [0002] With the development of the aquaculture industry, aquaculture wastewater has gradually become a new source of pollution due to the high breeding density and the increase in bait and excretion products. Nutrients such as nitrogen and phosphorus in mariculture wastewater are important pollution sources of water eutrophication, which increases the load of nutrients in adjacent waters year by year. In addition to the self-pollution of the aquaculture water body, the ridges of the large-scale shrimp ponds are also wasted. In the case of shortage of arable land and water pollution caused by aquaculture is becoming more and more serious, how to use aquaculture wastewater and aquaculture pond ridges has become an important issue. Contents of the invention [0003] In order to o...
