Problems solved by technology

[0003] There is a large demand for aquaculture fertilizers, but the overall level of the aquaculture fertilizer market is currently low. Therefore, research on special fertilizers is carried out, and special fertilizers suitable for fish, shrimp and shellfish farming are produced by adjusting the chemical structure of the main nutrient components and optimizing the process. has broad prospects

Embodiment 1

[0022] (1) 240kg of sugar residue, 45kg of peat charcoal, 12kg of molasses, and 3kg of acid bacteria were mixed and fermented for 5 days at a height of 60cm. The piles were turned over once a day, and the last time was diluted and cooled for later use.

[0023] (2) with 150kg molasses, 60kg diammonium phosphate, 100kg urea, 180kg chlorella concentrate, 180kg fish paste, 2kg ferrous sulfate, 3kg sodium metasilicate powder, 25kg amino acid with the dry material of (1) step fermentation gained The liquid is mixed and refined.

[0024] (3) The semi-finished product of step (2) is drawn into the fermentation tank for liquid fermentation for 15 days.

[0025] (4) The finished product of step (3) is canned and inspected. is the finished product.

[0027] Experimental data of fertilizer-water compound for aquaculture in seawater cofferdam

[0028] From April to May 2015, a 30-day experiment was carried out in the breeding base of Fujian Green Company. 2 ammonium bicarbonate + phosphate fertilizer + manure, ammonium bicarbonate + phosphate fertilizer, urea + phosphate fertilizer and seawater cofferdam aquaculture fertilizer-water compound agent were applied to each fertilizer, and three groups of repeated experiments were carried out for each fertilizer, and the water productivity and water quality during the experiment were quantified. Qualitative analysis yielded the following results.

[0029] Table 1 Effect of fertilizer and water compound agent on phytoplankton in seawater cofferdam culture

[0030]

[0031] From Table 1, it can be seen that the effect of seawater cofferdam aquaculture fertilizer-water composite agent on the growth of phytoplankton is obviously better than that of other fertilizers.

Abstract

The invention provides a cofferdam culturing seawater enriching compound agent. The cofferdam culturing seawater enriching compound agent is prepared from, by weight, 100-300 parts of candy pomace, 20-60 parts of grass carbon, 100-200 parts of molasses, 1-5 parts of enzyme strains, 20-80 parts of diammonium phosphate, 50-150 parts of urea, 75-200 parts of a chlorella concentrated solution, 75-200 parts of fish cream, 0.5-3 parts of ferrous sulfate, 1-5 parts of sodium metasilicate powder and 10-30 parts of amino acid liquid. According to the cofferdam culturing seawater enriching compound agent, mass rapid propagation of green alga, diatom and beneficial microorganisms is promoted, and a good culturing ecological environment is supplied to cultured organisms.

Description

technical field [0001] The invention relates to a seawater cofferdam aquaculture fertilizer-water compound and a preparation method thereof. Background technique [0002] "Fish raising water first", cultivating high-quality aquaculture water is of great significance in aquaculture, and algae-fertilizing water is an important part of cultivating a high-quality aquaculture environment in aquaculture. Nitrogen and phosphorus nutrients are indispensable nutrients for the growth and reproduction of phytoplankton. An appropriate amount of N and P nutrients is helpful for the growth of single-celled algae and some zooplankton in aquaculture water. The success or failure of the entire breeding process plays a decisive and important role. [0003] There is a large demand for aquaculture fertilizers, but the overall level of the aquaculture fertilizer market is currently low. Therefore, research on special fertilizers has been carried out, and special fertilizers suitable for fish, s...
