Less insecticide Before winter, many farming friends are accustomed to using insecticides in order to kill the insects in the water. It is not known that the use of insecticides has severely damaged the existing ecological environment, causing instability of the water body and a serious imbalance between the algae and bacteria. Wintering using this pool of water is very dangerous. Change the bottom In order to suppress the mass production of zooplankton in the ice and stabilize the water quality under the ice, it is recommended to use “Fu Di'an†before the winter to change the bottom 3 times to 5 times. A large amount of data has proven that Qin Di can effectively inhibit the breeding of “worms†in the water and stabilize water quality. Stable water Before the winter, many ponds have aged water and change greatly. At this time, farming friends are often used to use phosphorus fertilizer and other fertilizers to stabilize water quality. This kind of stable water method has high cost, poor effect and slow effect. In our one-year breeding process, the eutrophication of water bodies has been severe and there is no shortage of fertilizers. Once fertilizers are not used, they will immediately turn into harmful substances that will stimulate fish. In general, the use of “Clearwater Safety†and “Quick Solution Safety†can effectively relieve pool water aging, accelerate material circulation, and establish a stable water environment. Increase oxygen In the autumn, the aerator is normally opened during the day. It can adjust water and stabilize water. The aerator at this time is not just a function of aeration. Early decommissioning of aerators is not advisable. It is recommended that the use of autumn aerators be as open as possible during the day and appropriate at night. Only by accomplishing the above points can we lay a good foundation for the management of aquaculture ponds after wintering and sealing. These management key points are also important applications of "controlled ecological farming techniques" in production practice.
The chemical composition of traditional Chinese medicine is relatively complex, usually containing protein, amino acids, carbohydrates, oils, pigments, vitamins,

Organic salts, organic acids, volatile oils, alkaloids and other components. There are many types of traditional Chinese medicines used clinically, and each type of traditional Chinese medicine
All contain different ingredients, and some of these ingredients have obvious biological activity, and can play a medical role, more than The more common ones are volatile oils, alkaloids, amino acids, vitamins, etc. Chinese herbal medicines are said to be authentic. They refer to famous and high-quality medicinal materials with Chinese characteristics that are traditionally recognized by people and originating from specific production areas. generally accepted by patients. However, the classification criteria for the authenticity of traditional Chinese medicinal materials are mainly derived from practical experience, which is artificial, relative and vague. The quality of the same medicinal materials in the Dao production area is also uneven.Professional Drug powder manufacturer is located in China, including Canagliflozin Hemihydrate,Mitotane,Tasimelteon,Saxagliptin, etc.
Winter came to prepare a warm nest for the fish
In northern China, the winter climate is cold. The ice-sealing period lasts from 100 days to 130 days. How to ensure the safe wintering of fish is an important part of fishery production in the northern regions. In recent years, the losses caused by fish overwintering technology have been increasing, and fish deaths often occur in the middle and late winter. Fish overwintering technology is currently more systematic and every technical link is very important, and many people tend to ignore fish farming management before winter. Through a wide range of investigations and researches, we have summarized the key points for the management of fish breeding before winter.
