Problems solved by technology

Long-term seawater irrigation will lead to an increase in the salinity of the tidal flat soil, which will increase the salt content in the sea asparagus and affect its quality, and the application of fertilizers will not only increase the cost but also cause eutrophication of the offshore seawater due to the loss of fertilizers

Embodiment 1

[0034] A cultivation method of sea asparagus, comprising the following steps in sequence:

[0035] a. Seedling raising steps

[0036] Soak seeds in warm water at 50°C-70°C for 8-20 hours, accelerate germination, and sow after germination; mix the dew-white seeds with fine soil and drill them directly on the seedling field, and then cover them with crushed soil. 5Kg; After the seedlings emerge and grow to 8-10cm, select the well-grown seedlings and transplant them to the planting tube; in tropical areas, you can also directly raise the seedlings in the open air, and then rinse the grown seedlings off the soil and transplant them into the planting tube;

[0037] b. Transplanting and cultivation steps

[0038] Expand the planting platform in the shallow sea area; transplanting the seedlings in the greenhouse to the planting tube should be cultivated in the shallow water area for 7 to 10 days, and shade treatment can be carried out when the sun is strong, and the seedlings will t...

Embodiment 2

[0044] A cultivation method of sea asparagus, comprising the following steps in sequence:

[0045] a. Seedling raising steps

[0046] Soilless cultivation method: Sow whitened seeds or seeds that have not been germinated directly into the planting tube; sow 5 to 8 seeds per planting tube, and then put the planting tube into the seedling rack, and the seedling rack is placed on a floating plate in the greenhouse Soilless cultivation, the density is controlled at 100-300 tubes / m 2 , grow to 8-10cm, then remove the poorly growing seedlings, and keep two or three dominant seedlings in each tube;

[0047] b. Transplanting and cultivation steps

[0048]Expand the planting platform in the shallow sea area; in the soilless culture method, the planting tube is directly removed from the greenhouse, inserted into the planting hole of the platform, and then moved to the offshore area or seawater fish and shrimp pond;

[0049] c. Platform fixing steps

[0050] Anchor to fix the platfor...

Abstract

A marine asparagus cultivation method comprises following steps: a. raising seedling, b. transplantation, c. platform fixing and d. picking. A device for the marine asparagus cultivation method is characterized in that: the device consists of 1-20 pieces of buoyancy materials sheets which are connected with steel ropes through a connecting belt. Both ends of the platform are fixed by fixing belts which are connected with anchors through anchor ropes. Compared with the prior art, the invention has the advantages that: adopting the buoyancy materials platform made from foaming materials realizes non soil cultivation of such marine vegetables as the marine asparagus in offshore areas which largely expands plantation extent of such marine vegetables as the marine asparagus, also can effectively prevent and reduce eutrophication status of the offshore water area, promotes industrial structure adjustment and economic benefits improvement of offshore agriculture, as well as the development of offshore aquaculture, and enables sustainable development of the offshore agricultural plantation and aquaculture.

Description

technical field [0001] The invention relates to a cultivation method and a related device, in particular to a cultivation method and a related device of sea asparagus in offshore sea areas. Background technique [0002] Salt-tolerant sea vegetables are a new type of vegetable. From the perspective of foreign consumer markets, salt-resistant and seawater-resistant vegetables can adapt to the healthy consumption concepts of foreigners, and can gradually open up the international market. From the perspective of domestic consumption markets, people's consumption concepts in large and medium-sized cities in my country are on the rise. Changes are taking place, and the consumption of famous, special, high-quality and new vegetables is becoming a trend. It can lower cholesterol and blood lipids, and has a good effect on high blood pressure and diabetes. Seawater vegetables are also gradually on the table of ordinary people in China. They are sold in supermarkets in big cities such a...
