Scientific Fertilization Technology Essentials

The scientific fertilization technology can not only save resources more effectively, but also improve the utilization of fertilizers and prevent the occurrence of fisheries accidents. Therefore, master the following fertilization essentials.

1. Check the pool's fat and thin before fertilizing. Water bodies, water bodies, oil films, and chemical methods are usually used to determine the degree of body fat. If it is fertilizer, it may not be fertilized temporarily; if it is water, it should take corresponding measures to control the continued development of dominant populations; if it is thin, it should be appropriately fertilized according to the corresponding water quality, soil quality and environment.

2. The amount of fertilization depends on the structure and characteristics of the soil and the conditions of the pond, the thinness of the water quality, the depth of the pool water, and the level of fish farming methods.

3. The time of fertilization follows the principle of “a small number of times, less application of diligence”, giving full play to fertilizer efficiency, avoiding waste and improving efficiency. When the water temperature of the pond reaches 15°C, basal fertilizer should be applied and the foot should be fully used. When the water temperature reaches 20 to 30°C, the phytoplankton and zooplankton multiply in water, requiring a large amount of nutrient supply, and the amount of fertilization will increase accordingly, mainly increasing the number of times, and careful attention should be paid to fertilization on sunny days.

4. The frequency of fertilizer application will be adjusted according to the type of fertilizer, breeding object, pond condition and water color. Usually 20 to 25 °C 7 to 10 days interval; 25 to 30 °C, interval 4 to 5 days.

5. Fertilization method When fertilizing, first put "Tianchen Fishery Fertilizer" into the barrel or into a larger container, then dissolve and soak (approx. 5 to 10 minutes) evenly with water. Generally choose sunny noon, rainy day try not to apply. In the mixed application of nitrogen fertilizer and phosphate fertilizer, it is necessary to apply phosphate fertilizer first, followed by nitrogen fertilizer, then the order of “Tianchen fishing fertilizer” cannot be reversed, nor can it be carried out simultaneously. If nitrogen and phosphorus fertilizers are used at the same time, a toxic and non-fertilized metaphosphoric acid will be produced, which will not only reduce the fertilizer effect but also cause toxicity to aquatic animals.

6. Use of Organic Fertilizers and Inorganic Fertilizers According to the nature of fertilizers, some fertilizers can be used in combination, such as inorganic superphosphate fertilizers and organic fertilizers. In general, acidic fertilizers and alkaline fertilizers should not be used in combination. Mixing produces gas to escape or precipitate to make sufficient oxygen loss; or produce toxic substances such as: NH3, H2S, HPO3 (metaphosphate), etc., poison fish and destroy Water quality. “Tianchen Fishery Fertilizer” can be used alone. If it is used together with carbon and ammonia, it can be used together. If using urea together, it should be used separately.

7. "Ten taboos for fertilization"

(1) Avoid rain and fertilization:
There are at least four major drawbacks to fertilization on rainy days:
(1) The dim light of the weather is weakened, the photosynthesis of phytoplankton in the water body is not strong, and the absorption of nitrogen, phosphorus and other elements is poor;
2 There is more organic matter to be carried along with the water, so it is not necessary to rush to apply fertilizer.
3 The volume of water body increases, the effective concentration of fertilization decreases, and the fertilizer efficiency also decreases.
4 When flooding, fertilizer loss is large.

(2) bogey hot weather fertilization: when the weather is hot, the pressure is low, the water is low in dissolved oxygen, after the application of fertilizer, the organic oxygen consumption in the water is increased, which can easily cause the intensive nutrient pool to float due to lack of oxygen, and the pan pool; When the weather is hot, there may be heavy rain coming soon, and it will be a taboo for rain and fertilization.

(3) Taboo water fertilization: when the water is too turbid, it shows that there are too many clays and mineral particles in the water body. Some ions in the fertilizer are easily adsorbed, fixed and precipitated by the clay particles, which can delay the release of fertilizer efficiency and cause loss of fertilizer efficiency.

(4) Avoiding single application of chemical fertilizers: The purpose of fertilization is to cultivate phytoplankton and zooplankton that are easily digested by aquatic animals in the water body. After the flow of matter and energy, the animals are finally fed to feed water. Plankton absorption of nutrients is a certain percentage, generally requiring an effective ratio of nitrogen, phosphorus and potassium of 4:4:2. If a single chemical fertiliser is used alone, the nutrient elements of fertilizer effect are relatively single, then other nutrient elements will become limiting factors and restrict the full play of fertilizer effect.

(5) Avoid blind mixed application: When some acidic fertilizers and alkaline fertilizers are mixed and applied, gas volatilization or sedimentation is easy to occur and the fertilizer effect is lost; part of the ions of some inorganic salt fertilizers and some of the other fertilizers will lose the fertilizer effect; Some ions are also lost by soil colloids and lose their effectiveness. Therefore, not every fertilizer can be mixed. If it is really due to disease control and water quality adjustment, it is best to wait 3 to 5 days before applying “Tianchen Fishery Fertilizer” to avoid loss of fertilizer efficiency.

(6) Avoid high-temperature season fertilization: fertilization is most suitable for main fertilizing fish, fish and other fertilized fish. According to the growth law of earthworms and earthworms, the season of fish pond fertilization should be from May to October each year, and the water temperature should be at 22-30 degrees Celsius at noon on sunny days, but the higher the temperature, the better. Because in the high temperature season of July-August, many species of water in the water body tend to eat less plankton population. When water temperature exceeds 30°C, fertilization should be reduced. When the water temperature exceeds 35°C, fertilization should be stopped.

(7) Avoiding dry application of solid-state fertilizer: The fertilizer applied in dry form is granular. Due to its own gravity factor, the residence time of the fertilizer in the water surface is short, and it easily sinks into the bottom of the water and is adsorbed by the bottom sludge, thus affecting the fertilizer efficiency. For this reason, many fish experts likened silt to phosphorus traps. Generally, when the solid fertilizer is applied, it is best to use the first solution and dilute the water, and then the whole pool is splashed.

(8) Avoid fertilization of aquatic animals when they are not eating well or have an outbreak. Fertilization: Fertilizers are used when fertilized by aquatic animals. A large number of cultivated plankton cannot be used effectively in a timely manner, easily forming “bloom” and damaging water quality. In the outbreak of disease, the resistance of aquatic animals weakened, and it is easy to cause poisoning death.

(9) Avoid excessive application of fertilizer: If excessive application of ammonium nitrogen fertilizer will cause excessive accumulation of ammonia in the water, causing fish poisoning; at the same time excessive application of organic fertilizer, increase the oxygen consumption of organic matter in the water, easily lead to hypoxia And pan-tang. Therefore, when it comes to fertilizing, it must not be done. If the fertilizer is to be taken down at one time, the principle of fertilization with “a small number of times and less application” should be strictly followed. It is generally required that topdressing be applied once every 3 to 5 days so that the total effective nitrogen concentration of the pool water is always maintained at 0.3 mg/L or more and the total phosphorus concentration is maintained at 0.04 to 0.05 mg/L. Excessive fertilization with "Tianchen fish fertilizer" will not cause the above phenomenon, but it will cause waste of fertilizer and increase the cost of farming.

(10) After releasing fertilization, put surface water: After applying different fertilizers, after a series of physical and chemical reactions, can be converted into plankton after 3 to 5 days, the number of dominant populations reaches the peak around 4 to 7 days, and plankton The population is generally evenly distributed in the water surface 1 ~ 2m. If surface water is released after fertilization, the plankton cultivated will be reduced or reduced, resulting in a decline in fertilizer efficiency. If it is indeed due to the needs of agricultural water, bottom water should be placed.
The mastery of fertilization technology is to make the water become fat. The population and quantity of plankton that are easily digested by aquatic animals are large, but the dissolved oxygen in water is not too low, which affects the survival and growth of aquatic animals. Therefore, scientific fertilization should be mastered, and attention should be paid to the "ten fertilization for fertilization" mentioned above.
