A kind of water quality control agent of rice-shrimp co-cropping system and preparation method thereof

Abstract

The invention discloses a water quality regulating agent for a rice-shrimp co-cropping system and a preparation method thereof, and relates to a regulating agent in the field of aquaculture. Components and weight percentages of the regulator: 1) Main components: macromolecular natural organic matter: 2-5%; aluminum-containing minerals: 40-45%; calcium-containing minerals: 20-25%; acid salts: 5-10% %; 2) Additional components: binder: 5-20%; foam: 0.1-0.5%; moisture: 5-15%. The regulating agent can greatly reduce the organic matter, nutrients and heavy metals in the water body during the co-cropping of rice and shrimp, increase the dissolved oxygen in the water body, improve the water quality, create conditions for the healthy growth and development of crayfish, and ensure the economic benefits of the co-cropping system of rice and shrimp. Compared with the traditional treatment method of applying materials, this regulator has high efficiency in improving water quality, is ecological and environmentally friendly, and has no environmental risks.

Description

technical field [0001] The invention relates to a regulating agent in the field of aquaculture, in particular to a water quality regulating agent for a rice-shrimp co-cropping system and a preparation method thereof. Background technique [0002] The rice-shrimp co-cropping system is a comprehensive utilization model of rice fields that has developed rapidly in the past ten years. Due to its good economic effect and simple management, this model is very popular among farmers. However, with the addition of a large amount of high-protein feed, the accumulation of crayfish excrement, and the abuse of disinfectants, antibiotics and other drugs, the deterioration of the aquaculture water has been accelerated, especially during the Spring Festival every year, when the temperature rises, a large number of filamentous algae outbreaks, Death consumes a large amount of dissolved oxygen in the water body, resulting in insufficient dissolved oxygen in the water body, which seriously af...
