Embodiment 1

[0044] Example 1: Tomatoes were cultivated by utilizing wastewater from spirulina cultivation in Ordos area.

[0045] Tomato, also known as tomato and foreign persimmon, belongs to Solanaceae, Solanaceae, and tomato genus. The fruit is rich in nutrients and has a special flavor. It has the effects of losing weight, eliminating fatigue, increasing appetite, improving digestion of protein, and reducing bloating and food accumulation. Tomato likes temperature, the suitable temperature is 25-28°C during the day and 16-18°C at night.

[0046] According to the specific operation steps, the seeds with good germination were cultivated into seedlings through the whole nutrient solution, and three seedlings with similar growth were selected and transplanted into the water tank, and the Hoagland type full nutrient solution and the pretreated spirulina wastewater were used for nutrition respectively. liquid and untreated spirulina wastewater culture liquid, placed under the same room tem...

Embodiment 2

[0050] Example 2, using Spirulina culture wastewater in Ordos area to cultivate lettuce.

[0051] Lettuce, also known as naked oats, belongs to the order of cauliflower, Compositae, and the genus Lactuca. It is a sharp-leaved lettuce with young shoots and leaves as its products. The leaves are long lanceolate, light green in color, and crisp in texture. Tender, extremely tender, fragrant, with a unique flavor, containing a lot of vitamin A, vitamin B1, vitamin B2 and a lot of calcium, iron, protein, fat, and other nutrients, it is the top grade among raw vegetables, known as "phoenix tail" . Lettuce is heat-resistant, cold-resistant, strong adaptability, strong cold resistance, likes humidity, resists diseases and insect pests, has sweet and crisp quality, less fiber, and a suitable growth temperature of 20-25°C.

[0052] The preparation of lettuce hydroponic nutrient solution: dilute the spirulina wastewater stock solution 20-50 times and adjust the pH to 6.0-6.5 with hydroc...

Embodiment 3

[0057] Example 3, using spirulina culture wastewater in Ordos area to cultivate green chrysanthemum.

[0058] Green chrysanthemum, full name emerald green chrysanthemum cauliflower, also known as chrysanthemum leaves, is a kind of lettuce, belongs to the order Asteraceae, Compositae, Lactuca, and is eaten from the tender shoots and leaves of wild chrysanthemum. Chrysanthemum vegetables are rich in nutrients and have the effects of clearing away heat and detoxifying, regulating the appetite and lowering blood pressure. In addition to protein, polysaccharide, cellulose, vitamins and minerals, it also contains flavonoids and volatile oils. It is cool to eat, and has a strong chrysanthemum fragrance. It has a unique flavor and is cool and refreshing. It is very suitable for consumption in hot summer. Chrysanthemum likes a cool climate, and the optimum temperature for growth is 15-20°C.

[0059] Preparation of green chrysanthemum hydroponic nutrient solution: dilute spirulina wast...

Abstract

The invention discloses a method for cultivating vegetables in a water mode through spiral seaweed cultivation waste water. The method includes the following steps: carrying out processing such as filtering, diluting and pH adjustment on the collected spiral seaweed waste water; comparing the preprocessed spiral seaweed waste water with a standard total nutrient solution, and adding microelements necessary for plant growth to obtain a spiral seaweed waste water nutrient solution; soaking vegetable seeds into a clean culture dish, and placing the culture dish into a constant temperature illumination incubator till the seeds are sprouted; selecting sprouted seeds with the good growth conditions according to the sprouting states of the seeds, and transplanting the selected seeds into a Hogland type nutrient solution to cultivate seedlings; when the seedlings are grown to form plants, carrying out spiral seaweed waste water cultivation through plastic thin plates and water grooves; carrying out harvesting or transplanting. According to the method, the vegetables are cultivated in a water-planted mode through the spiral seaweed cultivation waste water, environment pollution caused by direct discharging of the spiral seaweed cultivation waste water is reduced, the waste water is changed into wealth, waste of water resources is reduced, and resource utilization of the spiral seaweed waste water is sufficiently achieved; meanwhile, the direction problem of the spiral seaweed cultivation waste water is solved, and the sustainable development of a spiral seaweed enterprise is also facilitated.

Description

technical field [0001] The invention relates to a method for hydroponic vegetable cultivation using spirulina culture wastewater, and belongs to the technical field of waste water resource utilization and soilless cultivation. Background technique [0002] In recent years, as a pure natural health food, spirulina has been deeply loved by the public. There are more and more spirulina breeding enterprises, and the scale of the industry is also growing. Located in Ordos City, the spirulina breeding base in Forte Kubuqi Desert has unique geographical, environmental, and climate conditions, and can produce high-yield natural polysaccharide Spirulina platensis. However, as a characteristic industry, the spirulina aquaculture industry tends to produce a large amount of spirulina wastewater due to the biological characteristics of spirulina and the limitations of the existing production technology in the process of large-scale cultivation. Due to the spirulina cultivation process, ...
