Problems solved by technology

[0004] When asparagus is cultivated, a large amount of miscellaneous algae such as red hair algae and green hair algae are often attached. When these miscellaneous algae are attached to fishing gear, they can also be removed by peeling after exposure to the sun, but the miscellaneous algae attached to asparagus Algae obviously cannot be eliminated by this method, otherwise the asparagus will die, but if the asparagus is not eliminated, it will not only rob the asparagus of nutrients and sunlight, but also mix the products and affect the benefits
[0005] Due to the lack of effective elimination methods, the asparagus can only be allowed to attach to the asparagus, or be eliminated manually after harvesting, which seriously affects the development of the asparagus industry.

Embodiment 1

[0022] The method for removing miscellaneous algae in asparagus cultivation comprises the steps:

[0023] 1) Prepare a pool, fill the pool with aquaculture wastewater, fish out the asparagus epiphytic algae from the breeding ground and press it into the aquaculture wastewater. The water level is limited to immerse the asparagus, and then cover the pool with a transparent film ;

[0024] 2) Cultivate asparagus in the breeding wastewater for 15 hours, take out the asparagus, rinse with clean water until all the algae fall off, and soak the asparagus in the nutrient solution for 1.5 hours;

[0025] 3) The asparagus soaked in the nutrient solution was cultured in sterilized seawater with a transparency of 1m for 10 days, and then the asparagus was moved back to the breeding ground to continue culturing.

[0026] Among them, the nutrients in the nutrient solution include ammonium bicarbonate, magnesium sulfate, boric acid, potassium chloride, adenine and indole butyric acid, ammon...

Embodiment 2

[0029] The method for removing miscellaneous algae in asparagus cultivation comprises the steps:

[0030] 1) Prepare a pool, fill the pool with aquaculture wastewater, pull out the asparagus of epiphytic miscellaneous algae from the breeding ground and press it into the aquaculture wastewater, the water level is limited to immerse the asparagus;

[0031] 2) Cultivate the asparagus in the culture wastewater for 10 hours, take out the asparagus, rinse with clean water until all the algae fall off, and soak the asparagus in the nutrient solution for 1 hour;

[0032] 3) Cultivate the asparagus soaked in the nutrient solution in sterilized seawater with a transparency of 0.5m for 7 days, then move the asparagus back to the breeding ground to continue culturing.

[0033] Among them, the nutrients in the nutrient solution include ammonium bicarbonate, magnesium sulfate, boric acid, potassium chloride, adenine and indole butyric acid, ammonium bicarbonate, magnesium sulfate, boric aci...

Embodiment 3

[0036] The method for removing miscellaneous algae in asparagus cultivation comprises the steps:

[0037] 1) Prepare a pool, fill the pool with aquaculture wastewater, fish out the asparagus epiphytic algae from the breeding ground and press it into the aquaculture wastewater. The water level is limited to immerse the asparagus, and then cover it on the surface of the aquaculture wastewater transparent film;

[0038] 2) Cultivate asparagus in the breeding wastewater for 12 hours, take out asparagus, rinse with clean water until all the algae fall off, and soak asparagus in nutrient solution for 1 hour;

[0039] 3) Cultivate the asparagus soaked in the nutrient solution in sterilized seawater with a transparency of 0.8m for 8 days, then move the asparagus back to the breeding ground to continue culturing.

[0040] Among them, the nutrients in the nutrient solution include ammonium bicarbonate, magnesium sulfate, boric acid, potassium chloride, adenine and indole butyric acid, ...

Abstract

The invention discloses a method for removing hybrid algae during cultivation of gracilaria lemaneiformis, and belongs to the technical field of cultivation of algae. The method comprises the steps of: filling a pool with cultivation wastewater, fishing gracilaria lemaneiformis growing with the hybrid algae out of a cultivation land, compressing the gracilaria lemaneiformis into the cultivation wastewater, carrying out cultivation for 10-15 hours, taking out the gracilaria lemaneiformis, rinsing the gracilaria lemaneiformis with clean water, soaking the gracilaria lemaneiformis into a nutrientsolution for 1-1.5 hours, culturing the gracilaria lemaneiformis in disinfected seawater for 7-10 days, transferring the gracilaria lemaneiformis back to the cultivation land, and continuing to carryout cultivation. The method for removing the hybrid algae is simple and efficient, the hybrid algae are suffocated by virtue of the characteristic that the hybrid algae cannot survive for a long timein an environment in which the water temperature is 17-25 DEG C and no air circulates, and meanwhile, the gracilaria lemaneiformis is cultivated by virtue of the cultivation wastewater, so that on one hand, the cultivation wastewater is purified by virtue of the gracilaria lemaneiformis, a wastewater treatment operation is omitted, on the other hand, nutrients required by growth of the gracilarialemaneiformis are supplied by virtue of the cultivation wastewater, and the cost for replenishing the nutrient solution is saved.

Description

technical field [0001] The invention relates to a method for removing miscellaneous algae in asparagus cultivation, and belongs to the technical field of seaweed cultivation. Background technique [0002] Asparagus (Gracilaria lemaneiformis) is a species of Rhodophyta, Cedaraceae, Gracilariaceae, and Gracilaria genus. C and N are the main components of the biomass formed by asparagus, so seawater can be fixed during the production process. A large amount of C, N, P, K and other major pollutants that cause eutrophication in offshore waters can effectively purify the water quality in aquaculture areas. At the same time, because of its high protein, low fat, rich in various minerals, vitamins and unsaturated fatty acids, Therefore, it is also a health food with broad development prospects. Asparagus is cold in taste, has the effects of softening and resolving phlegm, clearing away heat and diuresis, and asparagus is also the raw material for extracting agar. It can be seen that...
