Microorganism type grass control composition used in aquaculture

Abstract

The present invention relates to a microorganism water quality modifier, particularly to a microorganism type grass control composition used in aquaculture, wherein the microorganism type grass control composition comprises main raw materials, fillers and auxiliary materials, wherein the main raw materials comprise Bacillus subtilis, Baclicus lincheniformis, Lactobacillus plantarum, Lactobacillus acidophilus and other beneficial bacteria, the fillers comprise zeolite powder, sodium chloride, magnesium sulfate, calcium sulfate, calcium hydrogen phosphate, and sodium sulfate, and the auxiliary materials comprise pregelatinized starch, micro-powder silica gel, dextrin, a starch-lactose complex, glucose, magnesium stearate, and microcrystalline cellulose. According to the present invention, the Bacillus subtilis, the Baclicus lincheniformis, the Lactobacillus plantarum, the Lactobacillus acidophilus and other beneficial bacteria are directly pressed into the tablets with the diameter of 4-12 mm by using the tableting machine under the dry powder state, and during the use, the tablets can be directly sprinkled through manual or machinery manner so as to substantially reduce the labor intensity, and the tablets sink into the pool bottom portion heavy pollution zone so as to directly provide the effect and effectively improve the use effect.

Description

technical field [0001] The invention relates to a microbial water quality improver, in particular to a microbial weed control composition used in aquaculture. Background technique [0002] my country is a big country of aquatic product breeding, and the amount of aquatic product breeding ranks among the top in the world. However, with the improvement of people's living standards, traditional breeding species can no longer meet people's needs. Some special breeding species such as: river crab, sea cucumber, etc. Premium varieties have gradually entered people's tables. In order to meet the demand of the market, the breeding area is gradually expanding. [0003] The current traditional river crab and sea cucumber farming model is artificially simulating the natural environment. In the sea cucumber breeding ponds, stones are artificially piled up to form artificial "reefs", and sea cucumbers live in the reefs. In the process of river crab breeding, aquatic plants such as: Hyd...

AI Technical Summary

Problems solved by technology

[0005] 1. In the process of sea cucumber cultivation, as the seasons change, phytoplankton such as tube vegetables, Spirogyra, and wire grass appear in sequence, and the growth rate is very fast, which seriously affects the normal growth of sea cucumbers.

At present, there are two processing methods: 1. Manual fishing: time-consuming and labor-intensive, and with the increase of labor costs, the gain outweighs the gain

2. The use of chemical herbicides such as promethazine, atrazine and other triazine herbicides, but with the increase of drug resistance, the effect is getting worse. At the same time, if the sea cucumbers are not properly handled, drug residues will occur. It causes food safety problems. In addition, if the aquaculture water that uses a large amount of herbicides is not treated and discharged to the open sea, it will cause serious pollution to the water environment.

[0006] 2. In the early stage of river crab breeding, fertilizers should be used to accelerate the growth of aquatic plants to provide a good habitat for river crabs. However, as the water temperature rises, especially in the high temperature season of summer, the growth of Elodea accelerates, and even its head grows out of the water. However, in summer, the surface temperature of the water body is too high, which is very easy to burn it, causing the head of Elodea to sink, and even rot and deteriorate the water quality. How to control the growth rate of Elodea in summer is a difficult problem for river crab breeding.

This method is time-consuming

2. Use chemical drugs such as paclobutrazol and other plant growth regulators to control the growth rate of Elodea, but whether these drugs are suitable for aquaculture, whether they will pollute the water body and whether they meet the requirements of food safety have yet to be determined. further verification
