How to fertilize fish ponds

The purpose of fish pond fertilization is to increase the nutrients in the water and cultivate the food organisms in the pond. Only by selecting suitable fertilizers and mastering the right fertilization methods can the fish production be maximized.

Rationally apply inorganic fertilizers and organic fertilizers. Application amount of inorganic fertilizer: Calculated with an average water depth of 1.5 meters, every new hemp pond has 1/15 hectare (1 mu) of basic ammonium bicarbonate 6-8 kg or urea 2-4 kg; fertilization of old ponds should be reduced appropriately . Top dressing, the amount of fertilizer in the new fish ponds should be appropriately reduced. Topdressing, new fish ponds are applied every 7 days or so. The amount of base fertilizer is appropriate, and the time for topdressing in the old fishponds can be appropriately extended. Fertilizers used as base fertilizers or topdressing applications should all be splashed with water. The use of organic fertilizer in fishponds requires a flexible understanding of water quality and water temperature. Basal fertilizer applies 400-600 kilograms of decomposed human and animal dung per 1/15 hectare. When applying topdressing, it is necessary to reduce the use of facilities and apply it once every 7 days. The dosage per 1/15 ha is about 60 kg. When using domestic sewage, food industry waste, etc. as bait, care should be taken to avoid toxic substances entering fish ponds.

Fertilize according to farming conditions. Due to differences in fish species, culture density and breeding specifications, the types and quantities of fertilization are also different. The application of organic fertilizer in carp ponds should be based on green manure and human and animal manure, and the water color should be mungbean. Polyculture of cockroaches and squids should be based on the application of livestock and poultry excrement, and the water color should be tea-brown. For grass carp and carp ponds that are mixed with grass carp, only enough grass can be added.

Fertilize according to season, temperature, and water temperature conditions. The temperature and water temperature are high, the decomposition of fertilizer is fast, and the oxygen consumption is drastic. Therefore, organic fertilizers or inorganic fertilizers should be less applied to avoid oxygen-depleted flooding ponds. In spring and late autumn, the climate is suitable and fertilization can be appropriate. When dressing, pay attention to not apply when it rains, do not apply before pulling the net, and do not apply when the fish is ill. Fertilization should be carried out in the morning. It is better to apply it. Appropriate amount of fresh water should be added after fertilization to keep the water fresh.

Chemical Intermediate

Chemical intermediate, which is used to make dyes, pesticides, medicine, resins, auxiliaries, plasticizers, etc. from coal tar or petroleum products as Chemical Materials. In China, raw materials and intermediates for the production of 11 categories of fine chemicals are called chemical intermediates. Fine chemicals are classified into 11 categories, including pesticides, dyes, coatings, pigments, reagents and high purity substances, information chemicals, food and feed additives, adhesives, catalysts and various additives, chemicals and daily chemicals, and functional polymers in polymer. In China, raw materials and intermediates for the production of the above 11 categories of fine chemicals are called chemical intermediates.

The main chemical intermediates are:The main chemical intermediates are: 2 - Chloro - 2 - Methylpropane, Lithium Amide, Cyclopentyl Chloride, 4 - Allylanisole Bromocyclopentane.We can do Amino Acid subpackage, filling Healthcare Products in capsules and tablets to meet all your needs.
