1, organic fertilizer must be fully fermented The temperature of fish ponds in spring is low, and the oxygen content in water is relatively abundant. Rational application of organic fertilizers is not only cost-effective, but also can achieve good breeding results. Fish ponds, such as manure, livestock and poultry manure, must be fully fermented. Fermentation and decomposing of fertilizers with organic matter applied to fish ponds can reduce the consumption of oxygen in the water, can be quickly absorbed and used by phytoplankton, and can also kill pathogens in organic fertilizers. 2, the principle of fertilization Shi Heng Shi Qin Shi The so-called "less application" means that every application of organic fertilizer is from several tens of kilograms to one hundred kilograms per acre; the so-called "uniform application" means that the water and manure are poured evenly throughout the pond so that the color of the fishpond is yellow-brown or oil-green. No oil film, the transparency is maintained at 20 cm to 30 cm; the so-called "diligent", that is, with the fish feeding, whenever the pond water is reduced, the transparency is greater than 30 cm, immediately re-fertilize. It is not the fish pond that raises the main fish and fish. Since the feed is fed, the amount of fertilizer applied in spring needs to be reduced accordingly, so that the transparency can be kept between 30 cm and 40 cm. With the increase of temperature, the pond water will become more and more fat. Intensive breeding of fish ponds with high yields of squid and intensive culture of grass carp, although they have raised some squid and carp, they should not be fertilized in spring. 4, fertilization time sunny morning as well Pay attention to listening (looking) to the weather forecast, not fertilizing on cloudy or rainy days. Phytoplankton grows through photosynthesis and fertilizes in the morning on sunny days from 2 days to 3 days. It can quickly and best promote the proliferation of microorganisms, minimize the pollution of organic fertilizers on water quality, and ensure the benign circulation of fish and pond materials. . 5, change the water regularly to keep the water fresh Excessive accumulation of metabolic wastes of organic matter and various types of organisms in fish ponds, decreased oxygen levels in the water, and poor composition of plankton may affect the growth of farmed fish. Therefore, it is necessary to change the new water regularly so as not to overload the fish ponds and keep the water quality “fat, live, tender and coolâ€.
Goji Berry ( [Goji" means [happy") , also called wolfberry, has been used for thousands of years by herbalists in China to protect the liver, help eyesight, boost immune function, improve circulation, and promote longevity and overall well being. It has only recently gained popularity in the west, it has become so polar, in fact, the Time Magazine recently named the Goji berry as [super-fruit" of the year. A big reason why Goji berries have quickly become a favorite nutritional supplement is that its impressive list of ingredients. The Goji berry, also called the wolfberry, is a bright purplish red or purple red berry that comes from a shrub that is native to China. In Asia, goji berries have been eaten for generation in the hope of living longer.

3, due to fish system should determine the amount of fertilizer
Fish pond spring fertilization precautions
The role of fertilization in fish ponds is mainly the reproduction of plankton, epiphytic algae, zoobenthos, and other natural foods. After fertilization, microorganisms multiply, organic debris increases, providing abundant food resources for fish species such as cockroaches and cockroaches; Organic fertilizers can be eaten directly by fish such as cockroaches and clams. Fish pond fertilization in spring should pay attention to the following matters:
