Anti-Aging Superfood - Goji berries are
considered the world's most powerful anti-aging food. They're rated #1
on the ORAC (Oxygen Radical Absorbance Capacity) scale, which measures
the antioxidant level of foods. Antioxidants fight free radical damage
associated with diseases and premature aging. Dried goji berries contain
3 times the antioxidants of pomegranates!
Protect Eyesight - Goji berries contain two key
nutrients that support vision: lutein and zeaxanthin. Studies show that
consuming high amounts of lutein and zeaxanthin lowers the risk for
developing age-related macular degeneration, cataracts, and other eye
diseases.
Promote Skin Health - The vitamins in dried goji
berries can give your skin a healthy, youthful glow. The rich content of
vitamin A, vitamin C and zinc naturally occurring in goji berries helps
to improve skin tone and texture. Research suggests that vitamin C and
zinc act as antioxidants to lessen the harmful effects of UV radiation
on the skin.
Boosts Immune System - Goji berries contain even
more vitamin C per ounce than oranges. They are also high in the trace
element selenium, which fights bacterial and viral infections. Adding a
small handful of dried goji berries to hot teas or soups isn`t a bad
idea when the cold and flu season hits.
Good Source of Amino Acids - Goji berries contain
18 amino acids, including all eight essential amino acids. Our bodies
use this combination of amino acids to build the proteins we need. Since
we cannot synthesize essential amino acids from scratch, we must obtain
them through our diet.
Liver & Kidney Benefits - A compound found in
goji berries called betaine, is used by the liver to produce choline.
Choline supports the liver and kidneys by helping them expel toxins and
waste from the body.

1, manure, including humans, livestock, poultry manure, etc., is - a kind of good effect fertilizer, containing more nitrogen, phosphorus, potassium and other fertilizers, while containing a certain amount of calcium, sulfur, iron and other elements, suitable for Top dressing use. Since the nitrogen in the excreta is easily volatilized, it is capped and stored before use so that it can be used after fermentation. When the time of application is to be adjusted according to the conditions of the pool, the dosage should be determined according to the depth of the water, the fat and the activity of the fish, and the method of use a small number of times can avoid the sudden deterioration of water quality.
2. Fertilizer Fertilizer is a mixture of livestock and poultry excreta and litter. It also contains rich nitrogen, phosphorus and potassium. However, the litter contains more cellulose and the decomposition is slower. In the rural areas, manure pits are used to store or accumulate manure after decomposing. More basal fertilizer can also be used as top dressing. As a base fertilizer, the amount of mu is about 500 kg; for top dressing, it can be applied once every 7 days or so, and the dosage is about one-tenth of the basic fertilizer. The specific method is to stack the manure fertilizer in the corner of the pond, submerge it into water, and gradually subdivide the fertilizer into points, spread it into the water for the use of the baits, and the result is good.
3. Green manure includes all kinds of wild non-toxic, fast-decomposing grasses, leaves, twigs and stems and leaves of various cultivated crops, such as clover, broad beans (bean), water peanuts, water hyacinth, etc., can be used for fish farming. The material. These green manures are easy to harvest, have the advantages of low cost and quick effect. It can be used as a raw material for composting or it can be used directly as a fish pond. Generally, the straw is bundled and stacked on the edge of the pool, and the stones are pressed on the bottom of the water to allow them to smash, and fat fractions are precipitated to achieve the purpose of cultivating plankton.
4. Composting Composting refers to the use of manure and fodder to mix manure and fermentation. Production method: prepare enough grass and livestock, poultry manure; Layers are piled up in prepared pits or pits. First put a layer of grass, sprinkle a small amount (about 1%) of quicklime, put a layer of manure, load the pits, and add water. Simply immerse in water and seal the pit with a thin layer of mud. About half a month or so can be used. When used, uncover - part of the mud, take the juice in the fish pond.
Second, the type of inorganic fertilizer and application of inorganic fertilizer, also known as chemical fertilizers. This type of fertilizer is characterized by relatively simple nutrient content, and most of them are - fertilizers only contain - two kinds of fertilizers. The applied water is easily decomposed and soon becomes effective, so it is also referred to as "available fertilizer." Including nitrogen fertilizer, phosphate fertilizer, potash fertilizer and calcium fertilizer.
1. Nitrogen fertilizers Nitrogen fertilizers can be directly absorbed and utilized by phytoplankton. In the aquaculture industry, phytoplankton growth and reproduction are often used to increase the amount of filter-feeding fish and non-feeding baits. Nitrogen fertilizers commonly used for fish farming include ammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium chloride, and urea. These nitrogenous fertilizers that exist in the ammonium state can easily become gas volatilization and reduce the fertilizer effect in the case of alkali, so they cannot be mixed with alkaline fertilizers. Nitrogen fertilizers are also fast-acting fertilizers, which are suitable for top-dressing and base fertilizers. When basal fertilizer is applied, 1.5-2 kg can be applied per acre, and the amount of top dressing is 1/4--1/3 of the base fertilizer.
2. The commonly used phosphate fertilizers include superphosphate and phosphate rock. Phosphorus is generally absent from ponds. The application of phosphate fertilizers has a significant effect on the growth of plankton and aquatic organisms. Superphosphate is a water-soluble quick-acting fertilizer containing 16% to 18% of available phosphorus. Phosphorite ore is crushed by phosphate ore. The phosphorus compounds contained are mainly fluorapatite which is difficult to decompose. The availability of phosphorus is poor and the fertilizer efficiency is also slow. When using superphosphate as top dressing, the amount of mu can be 0.25 kg. Also cannot be mixed with alkaline fertilizers, otherwise it will play a chemical role, producing insoluble tricalcium phosphate and reducing fertilizer efficiency.
3. Potassium fertilizers Potassium chloride, potassium sulfate, and ash are common potassium fertilizers. They are all soluble in water. Under normal circumstances, the potassium in the pond water is sufficient. Therefore, the amount of potash fertilizer does not need too much. As a base fertilizer, the amount of mu is roughly 0.5 kg; for top dressing, the amount of base fertilizer can be 1/4--1/3. Plant ash contains more potassium and more alkalinity, and this property cannot be ignored when used in combination with other fertilizers. When using ash, it is best to moisten the ash and spread it evenly in the pond. It should also be pointed out that the ash should be kept dry, and if it is exposed to rain, its potassium content will be lost. Potassium fertilizer is usually mixed with nitrogen fertilizer and phosphate fertilizer. The ratio of nitrogen, phosphorus and potassium fertilizers in the mixed fertilizer is preferably 2:2:1.
4, calcium commonly used calcium fertilizer lime, slaked lime and so on. The application of calcium fertilizer has many functions, which can not only disinfect, but also neutralize acid water and provide the calcium needed for aquatic organisms. One of the most common and most suitable is quicklime, which is convenient and economical, can be used as a disinfectant for clear ponds, and can also be used as base fertilizer and top dressing.
5. Compound Fertilizer General refers to a chemical fertilizer that contains three or two of nitrogen, phosphorus, and potassium and is chemically processed. There are two kinds of elements called binary compound fertilizers, such as ammonium phosphate, potassium nitrate, etc.; contain three kinds of ternary compound fertilizers, such as potassium nitrate and so on. In addition, multiple compound fertilizers also contain three elements and some other elements. Application of compound fertilizer can meet the needs of plants for a variety of nutrients, its fertilizer effect is better than other fertilizers, and storage and transportation are also more convenient.
Third, fertilization should pay attention to matters Fertilizer to be targeted, should be based on thin and reasonable fertilization of water. Generally thin ponds and newly built ponds should be filled with basal fertilisers; old fish ponds with more fertilizer ponds and silt can be used without base fertilizers. In order to supplement the consumption of fertilizers in the water body and promote the bio-proliferation of the food, additional fertilizers are required for the fish ponds. Top dressing should grasp the principle of timely, uniform and less frequent.
The effect of fertilization should vary with the seasons, generally less in the spring and autumn (each time the amount can be more), and more in the summer (each time the amount should be less). Usually according to the weather, color and fish changes, apply fertilizer. Usually the weather is more sunny and more rainy days, or in the rainy days, the water is light and multi-purpose. When floating heads or diseases are found, they are not applied. In addition, in order to give full play to the different roles of various fertilizers, it is best to use organic fertilizers and inorganic fertilizers at the same time or in the actual production, so that they can complement their weaknesses.
When it is known that the water body is lacking in certain or certain fertilizer components, it is advisable to apply a certain kind of compound fertilizer or a single chemical fertilizer to compensate the deficiency. In short, fertilization has to take into account many factors, and it is often necessary to adjust it according to specific conditions in production practices in order to achieve good results.
I. Types and Applications of Organic Fertilizer Organic fertilizer contains manure, green manure, manure, and compost. These fertilizers contain inorganic salts such as nitrogen, phosphorus, and potassium, and organic substances such as proteins, fats, and sugars. Fertilizer effect is good and long-lasting, but it is slow after application, so it is also called "delayed fertilizer." Organic fertilizers will rot and decompose in water, consume oxygen in water, and release toxic gases (hydrogen sulfide, ammonia, carbon dioxide, etc.) will have a certain impact on the growth of fish. When applying, it is not appropriate to directly apply large amounts of fresh organic fertilizer directly to fish ponds. Instead, it should be cooked after the closed fermentation is appropriate.
