Problems solved by technology

The technical method currently used to improve the environment at the bottom of the pond is mainly to add microbial preparations (such as photosynthetic bacteria preparations, bacillus preparations, etc.) Microorganisms, sometimes it is difficult for exogenous microorganisms to grow and reproduce well in the complex environment of the breeding pond, and cannot achieve the desired effect, resulting in unstable use effects. In addition, the use cost of microbial preparations is high and the shelf life of products is short. To a certain extent also limits its scope of application

Embodiment 1

[0010] The method for preparing the improver of the bottom material ecological environment of the culture pond and improving the bottom quality environment of the culture pond with the improver is as follows:

[0011] The first step, prepare substrate improving agent, formula (percentage by weight) is as follows, chitosan 2%, fulvic acid 20%, sodium humate 60%, bentonite 18%, four kinds of raw materials that select for use, fineness is Above 80 mesh, when preparing, mix chitosan and sodium humate evenly, and then add fulvic acid and bentonite and mix evenly. The preparation after the four raw materials are evenly mixed is the substrate improver product. 50 g of substrate modifier was adjusted to 500 ml of suspension with water.

[0012] In the second step, in two aquariums with a length of 100 cm, a width of 50 cm, and a height of 50 cm, a comparison experiment of substrate improvement was carried out. The test water and bottom mud were collected from the prawn breeding pond. ...

Embodiment 2

[0014] The method for preparing the improver for the bottom material ecological environment of the breeding pond and using the improver to improve the bottom material ecological environment of the culture pond is as follows;

[0015] The first step, prepare substrate improving agent, formula (percentage by weight) is as follows, chitosan 1%, fulvic acid 10%, sodium humate 50%, bentonite 39%, four kinds of raw materials that select for use, fineness is Above 80 mesh, when preparing, mix chitosan and sodium humate evenly, then add fulvic acid and bentonite and mix evenly. The mixing process uses a mixer to mix mechanically. quality improver products. 6 kg of substrate modifier was adjusted to 60 liters of suspension with water.

[0016] The second step is to carry out a comparative test in two adjoining prawn culture ponds with an area of ​​2 mu and 3 mu respectively. When the seedlings are released, the water quality and the state of the bottom in the two ponds are similar. T...

Embodiment 3

[0018] The method for preparing the improver of the bottom material ecological environment of the culture pond and improving the bottom quality environment of the culture pond with the improver is as follows:

[0019] The first step, prepare substrate improving agent, formula (percentage by weight) is as follows, chitosan 1%, fulvic acid 10%, sodium humate 50%, bentonite 39%, four kinds of raw materials that select for use, fineness is Above 80 mesh, when preparing, mix chitosan and sodium humate evenly, then add fulvic acid and bentonite and mix evenly. The mixing process uses a mixer to mix mechanically. quality improver products. 30 kg of substrate modifier was adjusted to 300 liters of suspension with water.

[0020] In the second step, comparative experiments were carried out in two adjoining prawn culture ponds with an area of ​​13 mu and 11 mu respectively. When the seedlings were released, the water quality and bottom quality in the two ponds were similar. The two po...

Abstract

The modifier consists of chitosan 1-2 wt%, fulvic acid 10-20 wt%, sodium humate 50-60 wt% and bentonite 18-39 wt%. The modifier is mixed with water in 5-20 times to form suspension liquid, and the suspension liquid is applied to aquiculture pond once every 10-20 days in the amount of 0.5-1.5 Kg each Mu area. The present invention can improve the ecological environment of aquiculture pond obviously.

Description

technical field [0001] The invention relates to a preparation for improving the ecological environment of the culture pond bottom and its application method. technical background [0002] Improving the ecological environment of aquaculture ponds is an important measure to reduce the incidence of fish and shrimp, increase aquaculture production, and improve aquaculture efficiency. The bottom mud of the pond contains a lot of organic substances and nutrients. If the bottom mud is too silted, it will easily lead to hypoxia at the bottom of the pond, and the content of harmful substances such as ammonia nitrogen, nitrite, and sulfide will increase, which will damage the ecological environment for breeding. The digestibility of silt, reducing silt, and accelerating the circulation of organic matter and nutrients in aquaculture ponds are the key links to improve the ecological environment of aquaculture ponds. The technical method currently used to improve the environment at the ...
