Embodiment Construction
[0015] The discarded rice straw is crushed into 60-mesh particles, mixed with clay colloid and appropriate amount of quick-acting carbon source and slow-acting carbon source, and the bacillus bacteria are fixed on the rice straw particles through a granulator to make it a long-acting rich Carbon micro-ecological preparations are placed at the bottom of the pond. Beneficial microorganisms use the excess waste nitrogen and additional carbon sources in the pond to grow and reproduce, transform and remove nitrite and ammonia nitrogen that are toxic to fish and shrimp; at the same time, decompose the organic matter in the bottom mud to benefit the microbial cells themselves It can also be used as a source of fish and shrimp single-cell protein.

The invention is an ecological method of controlling nitrite in fish and shrimp pool, fixing helpful microbe particles on discarded crop stalks, then throwing these stalks in the bottom of the pool, so that the helpful microbes grow and breed by using surplus waste nitrogen in the pool and additional carbon source so as to eliminate harmful nitrite and amino nitrogen; simultaneously decomposes organic matters in bottom mud, and the helpful microbes themselves can act as the source of monocell protein of fishes and shrimps. It can not only implement resource utilization of the discarded matters but also promote ecological balance, implementing healthy breeding.
Description
technical field [0001] The invention relates to an ecological method for controlling nitrite in fish and shrimp ponds. Background technique [0002] Various wastes produced in the process of aquaculture, including residual bait, fish and shrimp excrement, dead biological residues, drugs, fertilizers, etc., they accumulate, decompose, and transform in the pond, forming a large amount of waste that is toxic to fish and shrimp. Various substances, such as nitrite, hydrogen sulfide, methane, ammonia nitrogen, nitrogen oxides, etc., deteriorate water quality and threaten the survival and normal growth of farmed animals. Especially under the conditions of high-density and intensive farming, a large amount of bait is fed, and the nitrite content in the water often seriously exceeds the standard, resulting in nitrite poisoning and the death of fish and shrimp, which has become a prominent and urgent problem in aquaculture. [0003] Nitrite is an intermedia...
