Embodiment Construction

[0025] The substrate improving agent in this embodiment is prepared according to the following mass percentages: 9.5% of compound potassium hydrogen persulfate, 4% of percarbamide, 43.25% of zeolite powder, and 43.25% of filler.

[0026] The filler is bentonite;

[0027] The preparation method of described high-efficiency compound type substrate improver is:

[0028] 1. Zeolite powder modification treatment, including the following steps:

[0029] a. Pass the zeolite powder through a 200-mesh sieve to obtain a powder, rinse with distilled water 4-5 times to remove soluble impurities, and dry in an oven at 105°C for 2 hours.

[0030] b. Mix and stir the dried zeolite powder and 2mol / L sodium chloride solution according to the ratio of 1g:1.5mL, and put it in a shaker for 4 hours at a speed of 150r / min.

[0031] c. Wash the shaken zeolite powder with distilled water for 4-5 times, and continue drying in an oven at 105°C for 2 hours.

[0032] d The dried zeolite powder is burn...

Abstract

The invention provides a high-efficiency compound type substrate improver and belongs to the technical field of substrate environment regulation and control. The high-efficiency compound type substrate improver comprises the following formula composition by mass percent: 5%-20% of compound potassium hydrogen sulfate, 1%-20% of Percarbamide, 20%-60% of zeolite powder and 30%-50% of a filling agent; all the ingredients are pressed into cylindrical pellets with the diameter of 4-10 mm and the mass of 0.1-0.2g after being mixed in a proper proportion. According to the substrate improver provided by the invention, the ingredients are added in a scientific proportion, the functions of oxidation, oxygen supply, adsorption and the like are integrated into one, the substrate environment can be effectively improved, and cultured organisms are promoted to grow.

Description

technical field [0001] The invention relates to a high-efficiency composite substrate modifier, which belongs to the technical field of substrate environment control. Background technique [0002] In recent years, breeding has gradually become a new hot national economic industry. However, the rapid development of aquaculture and the irregular operation under the intensive aquaculture mode have led to increasingly serious problems of hypoxia in the substrate environment, accumulation of harmful substances, and disease problems. The important reason for this result is that the decomposition of organic matter in the substrate consumes a large amount of oxygen. . Under the condition of sufficient dissolved oxygen in the substrate, the organic matter fragments will combine with oxygen and eventually produce non-toxic substances such as carbon dioxide and water. Once the dissolved oxygen is insufficient, the organic matter fragments will form nitrite nitrogen, organic acids, alc...
