Problems solved by technology

Among the physical methods, there are mainly direct filtration, mechanical removal and microfiltration to remove algae, but there are defects of low removal rate; chemical methods such as throwing oxidants or powders may have a negative impact on the water body; and biological methods, especially the use of Plant allelopathy inhibition of algae is considered to be a new type of biological algae inhibition technology, which has attracted much attention due to its high efficiency and good ecological safety.
[0004] However, the existing various algae inhibitors cannot selectively inhibit the harmful algae of cyanobacteria, and also damage the beneficial algae and beneficial microorganisms in the water body to a large extent when inhibiting cyanobacteria, and the algae inhibitory effect and effective time are not the same. not ideal

preparation example Construction

[0019] At the same time, the present invention discloses a method for preparing the above-mentioned natural plant matter-selective algastatic agent, and the operation steps are as follows:

[0020] (1) Take Wedelia, Calamus, and Sagittarius, and grind them into powders of 50-200 meshes, and then store them at room temperature and pressure for later use;

[0021] (2) Mix the bacillus powder and the nitrifying bacteria powder according to the mass ratio of 1.5:1 to make a compound beneficial bacteria group, and store it at room temperature for later use; mix the cellulase and phytase according to the mass ratio of 1.3:1 Prepare compound biological enzymes and store them at room temperature for later use;

[0022] (3) Weigh each component according to the following mass percentages: 70%-20% of Wedelia powder prepared in step (1), 5%-20% of calamus prepared in step (1), 5%-10% of step ( 1) The obtained arrowhead mushroom powder, 0-10% of the compound beneficial bacteria obtained ...

Embodiment 1

[0026] Wedelia, calamus and arrowhead were taken and crushed into 150-mesh powder respectively, and then stored at normal temperature and pressure for subsequent use; the Bacillus powder and the nitrifying bacteria powder were mixed at a mass ratio of 1.5:1 to make a composite beneficial flora, Store at room temperature for later use; mix cellulase and phytase at a mass ratio of 1.3:1 to make a compound biological enzyme, and store for later use at room temperature; weigh 700g of Wedelia powder, 150g of calamus powder, and 50g of arrowhead mushroom powder , 50g of compound beneficial bacteria, and 50g of compound biological enzymes are mixed at normal temperature and pressure to form a mixture, and then the mixture is dried to obtain a light yellow powder product, which is an algastat; finally, the obtained algastat is packed into a packaging bag, vacuum Pack and seal.

Embodiment 2

[0028] Wedelia, calamus and arrowhead were taken and crushed into 200-mesh powder respectively, and then stored at normal temperature and pressure for subsequent use; the Bacillus powder and the nitrifying bacteria powder were mixed at a mass ratio of 1.5:1 to make a composite beneficial flora, Store at room temperature for later use; mix cellulase and phytase at a mass ratio of 1.3:1 to make a compound biological enzyme, and store for later use at room temperature; weigh 800g of Wedelia powder, 50g of calamus powder, and 50g of arrowroot powder respectively , 50g of compound beneficial bacteria, and 50g of compound biological enzymes are mixed at normal temperature and pressure to form a mixture, and then the mixture is dried to obtain a light yellow powder product, which is an algastat; finally, the obtained algastat is packed into a packaging bag, vacuum Pack and seal.

Abstract

The invention provides a natural plant selective algistat. The natural plant selective algistat is composed of the following components in percent by mass: 70%-20% of wedelia chinensis, 5%-20% of acorus calamus, 5%-10% of sagittaria sagittifolia, 0%-10% of composite effective microbial community, and 2%-10% of composite bio-enzyme, wherein the composite effective microbial community is composed of bacillus powder and nitrobacterium powder in mass ratio of 1.5 to 1, the composite bio-enzyme is composed of cellulase and phytase in mass ratio of 1.3 to 1. The invention discloses a preparation method of the algistat at the same time. The algistat provided by the invention is capable of selectively inhibiting harmful algae such as blue-green algae, and capable of avoiding harming of useful algae and useful microorganisms in a water body to a relatively great degree while the blue-green algae are inhibited, and capable of relieving the eutrophication of the water body to a certain degree, and is easy to store; the algistat is easy to operate and is suitable for large-scale application.

Description

technical field [0001] The invention relates to a microecological regulating preparation and a preparation method thereof, in particular to a natural plant matter selective algae inhibitor and a preparation method thereof. Background technique [0002] In recent years, with the increase of human activities, the eutrophication of lakes, reservoirs and rivers has become increasingly serious, which has changed the ecological structure and function of water bodies, resulting in the abnormal reproduction and growth of algae, especially cyanobacteria, and the phenomenon of cyanobacteria blooms. Large-scale algal blooms are known as "green tides". Green tides cause water quality to deteriorate, and in severe cases deplete the oxygen in the water and cause the death of fish. [0003] Therefore, effectively inhibiting the excessive growth of planktonic algae in eutrophic water bodies and preventing the occurrence of algae blooms has become a research hotspot and frontier in the fiel...
