Description

Controllable fish-vegetable symbiotic nutrition intermittent supply device and supply method thereof
Technical Field
The invention belongs to the technical field of aquaculture, and relates to a controllable fish-vegetable symbiotic nutrient solution intermittent supply device and a supply method thereof, in particular to a device for realizing supply of different nutrients in different time periods through a control device, which not only ensures full utilization of excessive nutrient substances generated in the culture process, but also realizes normal growth of planted vegetables through supplementary nutrient substances (calcium, potassium, iron, microorganisms and the like).
Background
In aquaculture, due to accumulation of fish excrement, ammonia nitrogen in water is increased, so that the production environment is seriously influenced, and the aquaculture of fish is not facilitated. However, direct drainage requires strict compliance with environmental regulations, and strict tail water treatment requirements can increase the cost of farming; water is frequently changed in the culture process, and waste of water resources is caused. Therefore, aiming at the problem, the fish-vegetable symbiosis appears as a novel agricultural cultivation form combining aquaculture and soilless culture, and provides a solution for purifying water quality environment and realizing the cyclic utilization of aquaculture water.
The growth of crops needs various different nutrient substances, and the nutrient components which can be provided for the crops in the aquaculture process include most commonly produced ammonia nitrogen and the like and also various nutrient components. However, if the aquaculture water is used for soilless culture of crops for a long time, malnutrition and even death of crops are easily caused, such as the shortage of calcium, potassium, iron and various microorganisms in the aquaculture water. Therefore, in order to improve the efficiency of the fish-vegetable symbiotic system and the survival rate of crops, nutrient substances with insufficient content in the culture water need to be supplemented.
The existing fish and vegetable symbiotic system is mostly in an open loop mode, namely, the aquaculture tail water is supplied to crops as irrigation water and then discharged as wastewater, and circulation is not formed, so that the water resource cannot be fully utilized, and the aquaculture cost is increased. In addition, the soilless culture plants are soaked in the nutrient solution for a long time, so that the growth of the plants is not facilitated; if excessive nutrient substances are supplemented to circularly enter the aquaculture water, the burden is caused to the aquaculture water body, the growth of fishes is not facilitated, and even the health of the fishes is damaged.
Therefore, to the above problems, it is desirable to provide a cyclic and controllable fish-vegetable symbiotic nutrition device, which not only improves the efficiency of aquaculture and crop planting, but also reduces the waste of water resources.
