Calcium, magnesium and phosphate fertilizer should be fed after the fish

Calcium, magnesium, and phosphate contain three elements: calcium, magnesium, and phosphorus. They are the main components of floating organisms in fish breeding water, and they have lower prices. It is more economical to use calcium magnesium phosphate fertilizer. However, calcium magnesium phosphate fertilizer is insoluble in water. Sprinkle in the water, it is impossible to fertilize fish water quality in a short time. Therefore, the calcium magnesium phosphate fertilizer is applied to the fish pond after fermentation, the effect of fertilizer and water is good, and the production is convenient.
The method of fermenting calcium, magnesium, and magnesium fertilizers is: mixing 100-200 kg of calcium magnesium phosphate fertilizer with 200-250 kg of poultry manure water and 150 kg of vegetable fertilizer mud in the vegetable garden. The temperature is hand-kneaded into a group and the ground is scattered. It should be piling up into towers after mixing, and the surface should be tapped on the back of the iron shovel or the wood plate. Finally, it should be covered with plastic film or sealed with thin slurry. The stacking can be started after 20-25 days. After fermentation, 63.8% of calcium magnesium phosphate was dissolved and transformed. Therefore, 30 kg fermented calcium magnesium phosphate fertiliser was applied every 15 days for every acre. After 3-5 days, the water of the fish culture was green or green or brownish green, and the transparency should be maintained at 25-30 cm. This is the best, which shows that the applied fertilizer is quickly absorbed by the floats, and it reproduces in large quantities, meets the fish's feeding needs in time, and has good fertilization effect.
After several years of investigation and comparison and personal practice, the author discovered that in the case where the amount of fertilizer is not changed and the species, size, and quantity of the polyculture fish in the same water body are constant, the fish pond of fermented calcium magnesium phosphate fertilizer is used. Fish), increase 30-45 kilograms per acre, other such as grass carp, carp have different degrees of increase in production. Therefore, the local fish farmers have said that "calcium magnesium phosphate fertilizer is not fermented, apply to the fish pond is also sleeping" is a profound scientific reason.
