Autumn is the best season for holding the yellow pheasant. As long as you have mastered basic stocking techniques and simple transportation methods, you can earn a rich regional and seasonal price difference. It is a new project for “short, flat, and fast†enrichment.
First, the tanks, barrels, and other containers used for storage should be washed and disinfected. For a container with a capacity of 60 kg, when the temperature is 20°C to 30°C, 30 kg of astragalus can be raised and 25 kg of fresh water can be added. Start changing the water every half an hour, change the water for three to four times, and then change the water every four hours to six hours. The water temperature and quality of the new water exchanged should be basically the same as that of Dianchi Lake. Well water, spring water, polluted water, and water with large temperature difference cannot be used. Every three or four hours, use your hand to reach the bottom and stir it up once to turn the squid on the bottom of the container up as far as possible to prevent the weak seedlings from suffocating and suffocating. It is also possible to place a loach that accounts for 10% of the weight of the carp in the holding vessel and use them to move them up and down to prevent them from becoming entangled in each other. It should be noted that, before raising jaundice, it is necessary to directly use the fresh cricket caught in the urn pool. After catching the oyster, the dirt and dirt on the surface of the oyster should be washed first, and the disabled can not be raised. . It is impossible to go to the market to acquire astragalus that has been trafficked to the disabled for storage. Otherwise, it will result in high mortality and great losses.
Fluorine-Containing Benzonitrile
Most products of Fluorine-containing Benzonitrile is a colorless transparent liquid and has a pungent odor. It was widely used in pesticides, pharmaceuticals liquid crystal material manufacturing. High efficiency, low toxicity and residue characteristics. Through extensive research and production practice, we have found some good manufacturing processes of fluoro-containing cyanophenyl products. In addition, we have groundbreaking research on ratio of raw materials, solvent selection, the choice of solvent concentration, related use of catalysts..
