specific Embodiment approach 1

[0027] Specific implementation mode one: the method for cultivating water body of this embodiment to control harmful algae stable ecosystem, it carries out according to the following steps:

[0028] 1. Detect the content of ammonia nitrogen, nitrite, dissolved oxygen, pH value, alkalinity and hardness in the water body, and at the same time detect the algae phase in the water body with a microscope. The water body whose test result does not meet the stable water standard is regarded as the water body to be treated;

[0029] 2. If the harmful algae species in the water body to be treated do not form dominant algae species, add 0.25 kg / mu m of algae balance element to the water body to be treated on the first day;

[0030] Add full-effect chlorella 3-5 liters / mu m, directional green algae fertilizer 0.1-0.5 kg / m and diatom vigor 0.2-0.5 kg / mu from 8:00 to 10:00 on the second day. Meter;

[0031] Add full-effect chlorella 1-3 liters / mu.m, directional green algae fertilizer 0.1-0...

specific Embodiment approach 2

[0034] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the water body indicators of the stable water standard described in step 1 are as follows: dissolved oxygen 5-12 mg / L, ammonia nitrogen 200mg / L, algal phase is dominated by small green algae or diatoms without algae toxins. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0035] Specific embodiment three: The difference between this embodiment and specific embodiment two is that the dominant algal species refers to the number of microgreen algae without algae toxins or diatoms without algae toxins, accounting for 50% to 70% of the total number of algae species. %. Other steps and parameters are the same as in the second embodiment.

Abstract

The invention discloses a method for controlling harmful algae and stabilizing the ecological system in aquaculture water, and relates to the technical field of aquaculture algae water diversion. It needs to solve the problems of a large number of harmful algae breeding in the existing aquaculture water, serious pollution of the water environment, failure of aquaculture, and irreversible harm to the environment caused by the extensive use of chemical disinfection products. Method 1: no outbreak; add algae balance element; add full-effect chlorella, directional green algae fertilizer and diatom vitality element; add full-effect chlorella, directional green algae fertilizer and directional diatom fertilizer. Method 2: Already broke out; add detoxified algae, super-effective bacteria and concentrated photosynthetic bacteria; add detoxified algae, super-effective bacteria and concentrated photosynthetic bacteria; add full-effect chlorella, directional green algae fertilizer and diatoms Vitality factor; add full-effect chlorella, algae power and directional diatom fertilizer. The invention can continuously maintain the water quality index and the stability of the algae phase, improve the breeding yield and quality, have obvious effects of water quality regulation, and be environmentally friendly. The invention is suitable for controlling harmful algae and stabilizing ecological system in aquaculture water.

Description

technical field [0001] The invention relates to the technical field of aquaculture algae water diversion. Background technique [0002] The rapid development of the industrial and agricultural economy in recent years has brought overload to the environment, especially the discharge of a large amount of organic matter into the water body, and the eutrophication of the aquaculture water environment is serious. In order to pursue high returns and high profits, farmers carry out high-density, high-feeding intensive farming techniques, resulting in high unit yields. At the same time, a large amount of feed input and high-density breeding metabolites lead to more and more organic pollutants in the pond, and the endogenous pollution of the pond is aggravated. These substances themselves and the nitrogen, phosphorus and other nutrients produced after decomposition Pond and organic pollutants will cause the deterioration of the pond culture environment to varying degrees, resulting ...
