1. The determination of the amount of feed: The feed contains the nutrients needed by the fish, mainly used to maintain the life of the fish, the need for growth, development, feeding the feed is too low only to maintain the life of the fish, feeding too much waste Reasonable feeding should make the fish grow fast and the actual effect of the low feed coefficient. The general use of food bait, daily bait rate of l% ~ 5%. How much it feeds depends on the temperature of the water. For example, the entire amount of bait is 100. In January, the water temperature is low and you can not vote. When the water temperature reaches 10°C or more in March, it can be used for less investment and 2% for the whole month, 6% for April, 9% for May, 12% for June, 16% for July, and 18% for August. %, 21% in September. It accounted for 14% in October, 2% in November, and it could not be voted in December. In short, the first half of the month was supplemented by feeding, and in the second half of the year, it was dominated by feeding and appropriate topdressing. Mainly adopting grass carp for water culture. When baited in March, it uses baits for food. In October, it uses fine feeding for fattening. From June to September, it mainly uses green fodder. If the green material is insufficient, it can be supplemented with proper concentrate feed. When feeding, according to the fish's eating and drinking ability, the water quality is thin and the weather condition is flexible. The fish population has low appetite, the water quality is too fat, and it is easy to float and flood the land. To invest less or not, the water quality can be more thin; When the weather is clear, the fish eat well, can vote more, rainy days and hot weather, to less vote, feed within 3 hours to eat less to vote. The quality of feed must be high quality, fresh, and non-corrupt.
2. Feeding times: Due to the feeding of the stomach-free fish, eating slowly, feeding too few times, can not effectively use feed. It is usually fed 2 to 3 times a day. When the water temperature is high, the growth season can be increased once. When the water temperature is low, it should be reduced once. From April to May, it should be fed twice a month. In June, it should be fed 3 times a day. In July and September, it should be daily 4 Times, 2 or 3 times in October, before April and after October.
3. Feeding time: When feeding once a day, it is good to be 10-1 l in the morning. When feeding twice a day, the first time around 9 am, the second time in the afternoon 3 to 4 points. When baiting three times a day, the first time at 8-9, the second at 12 o'clock and the third at 5-6 o'clock in the afternoon, this can't be too late because the oxygen consumption of fish will be Dramatic increase. It is easy to cause hypoxia at night and floating heads.
4. Feeding sites: Fixed feeding sites are good for feeding fish. Feeders can usually be set up. Larger water surfaces can be set up. The feed table is set up, with a mat, and it is fixed on four bamboo rafts around and inserted in the sunny place of the fish pond. The mat sinks to the surface one foot deep and serves as a food table for feeding bulk feeds such as bread and bran. The table is brushed and disinfected every 2 to 3 days. Feed table area is generally 1 to 2 square meters, set depth, depending on the type of fish, size and season. To feed green feed such as duckweed, dry grass, etc., a floating bait station is to be set up, and the feed box is tied into a square or triangular box with a bamboo raft. The area is 10-20 square meters. The feed box is generally set on the northern bank of the pond, near the shade of the sun, close to On the shore, it is fixed by wooden stakes. When feeding, spread the floating feed evenly and do not pile up.
Cosmetic ingredients are too broad a range. Our industry is usually divided into: 1. Basic ingredients, water or oil The main basic ingredients of general skin care products are distilled water or purified water, oil is vegetable oil or animal oil or mineral oil, according to the form of oil: liquid oil, semi-solid fat, solid wax. 2. Added ingredients, functional ingredients or control and adjustment ingredients Functional ingredients are mainly moisturizing, whitening, anti-aging, acne and other effective ingredients, according to different processes, plants as extracts, other organisms as extracts. Control components are preservatives, antibacterial agents, thickeners, emulsifiers, flavors, pigments and so on. Preservatives ensure that the product will not rot and deteriorate, antibacterial agents ensure that the product will not be infected by fungi, thickener to adjust the viscosity and flow variation, emulsifier to determine the product evenly dispersed into another substance, essence and pigment to ensure the stability of product smell and color. So, I don't know if that's what you want to know? Or do you want to know the names, the structures, the properties of the various monomer components, and if you want to know about that you can go to the INCI directory and Cos Dna for details
