Now with the implementation of the national “ecological priority, combination of catching and catching, and raising the main†modern fishery policy, the traditional “large row and large irrigation†method of aquaculture ponds has not adapted to the needs of the new situation and sustainable development. The “fish-rice symbiosis†technology can effectively improve water quality and achieve standard discharge of aquaculture water, which explores a new way for the sustainable development of pond fisheries.
1. Purify water quality
After planting rice on the surface of the pond, the rice needs to absorb a large amount of eutrophic substances such as nitrogen and phosphorus in the water. The removal rate of nitrogen and phosphorus can reach more than 60%, the transparency can be increased from 20~30cm to more than 50cm, and the transparency of rice planting area is more than 100cm. The quality of fish farming has reached the discharge standards of the Ministry of Agriculture, and the water quality has improved significantly.
2. Reduce fish disease
A large number of studies and practices have proved that parasites and pathogens in fertilizer water bodies are multiplied more than parasites and pathogens in lean water bodies. The fertilizer and water environment is more conducive to the growth of parasites and pathogens, especially pond sediments, more commonly known as parasites. A hotbed of pathogens. Through the fish-rice symbiosis technology, the pond sediment can be loaded into the planting alfalfa, which not only fixes the seedlings, but also provides nutrients for the early seedlings, which reduces the damage of the pond sediment. At the same time, the rice growth will consume a lot of nutrients such as nitrogen and phosphorus in the water. To make the water thinner, thin water is not conducive to the growth of parasites and pathogens, objectively reducing the density of parasites and pathogens, and reducing the risk of fish disease.
3. Improve the quality of aquatic products
The water is good, the chances of the fish getting sick are less, the dosage is inevitably reduced, not only saves the cost of medicine, but also the less use of medicine, which is conducive to ensuring the quality and safety of aquatic products and improving the quality of aquatic products. This is also "good water to raise good fish" The truth.
4. Get quality rice
The rice produced by the "fish and rice symbiosis" technology, because rice is not fertilized during the whole process of growth, does not fight drugs, and the rice quality is very good. It has been repeatedly tested by Wanzhou District Agricultural Products Quality Inspection Center, Wanzhou Food and Drug Administration, Shenzhen Pune Testing Group. Testing, rice does not contain pesticides, mercury, cadmium, arsenic, lead, chromium content is extremely low, and some are still lower than the instrument detection limit, fully in line with national rice quality standards and green quality standards.
5. Harvesting green fodder
After the rice is harvested, the cyan straw can be harvested in batches to feed the grass carp in a timely manner to become a high-quality green fodder for the grass carp. After the straw is collected, the sorghum can be turned over and folded into the sputum (higher than the water surface), and the black stalk is directly sown. Wheat straw, after more than one month, when the ryegrass grows to a height of more than 30cm, the ryegrass can be cut to feed the fish.
6. Improve the pond landscape effect
Planting rice, planting flowers, and growing vegetables on the surface of the pond is a different kind of landscape that enhances the pond landscape effect and is more beautiful than a single pond water surface.
7. Increase revenue
The “rice-fish symbiosis†system can increase the income of 50-80 yuan per 667m2 of rice; about 50kg of harvested fish, according to the market price of 2.5 yuan/kg, the output value can reach 500 yuan, and the cost is removed. The net income per 667m2 is 300~400 yuan. .
Well, the above is all about the symbiotic effect of fish and rice. If you are still hesitant about the fish-rice symbiosis technology, you can first refer to its role and advantages!
