Preparation and application method of multifunctional composite microbial agent for aquatic plant maintenance and water body bioremediation

Abstract

The invention provides preparation and application methods of a multifunctional composite microbial agent for aquatic plant maintenance and water body bioremediation. The multifunctional composite microbial agent comprises EM bacteria, potassium sulfate, plant growth regulators, microelements and molasses. The multifunctional composite microbial agent is reasonable in component, and contains multiple microbial agents, plant growth regulators and microelements, which are mixed and fermented to prepare the multifunctional composite microbial agent. Growth of aquatic plants can be promoted while water is purified, organic substances in bottom mud are decomposed and the ecological environment of the bottom of a pool is improved. In addition, necessary nutrients for growth of aquaculture animals can be provided, and the disease resistance of aquaculture animals can be effectively improved. The preparation method of the multifunctional composite microbial agent is simple and feasible in process, high in production efficiency, low in application cost, simple in operation and easy to implement; and the product is stable in quality, convenient to apply and good in adaptability and has relatively high popularization and application value.

Description

technical field [0001] The invention belongs to the field of agricultural science and technology, and in particular relates to a multifunctional composite bacterial agent, and a preparation and application method of the multifunctional composite bacterial agent, especially but not limited to application to aquatic product cultivation. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly and has become the world's largest producer of aquatic products, while pond aquaculture has become the most important aquaculture production method in my country, and its annual output accounts for 70% of freshwater aquaculture production. However, an excellent breeding ecology is conducive to the healthy growth of farmed animals, and it is also an important guarantee for the sustainable development of aquaculture. At present, the improvement of pond culture production and benefit is mainly achieved by greatly increasing the stocking density...

Problems solved by technology

Increased breeding density of aquatic animals and one-sided pursuit of production have also brought increasingly prominent problems: on the one hand, untreated aquaculture wastewater is directly discharged into water sources, leading to water pollution of receiving water bodies and triggering a large number of blue-green algae outbreaks; on the other hand , Excessive use of bait and drugs can easily lead to the deterioration of the ecological environment in the pond, and greatly increase the incidence of farmed animals, and a large number of drugs to treat diseases will reduce the quality of aquatic products and...
