The four secretive tricks

Feeding jaundice in cages is the most economical and effective way of farming. Ren Chao, a science and technology commissioner from the Central District of Neijiang City, Sichuan Province, introduced the four tips for the cage culture of Astragalus -
The cubs choose to observe the body surface. Astragalus has red blood clots on the body surface, which is rot disease; whitish flocculous tails, which is hydromycosis; the head is thin, and even stiff, curly and trembling; it is an internal parasite; anal swelling is prominent, For enteritis disease. In addition, the body is weak, there is little mucus, floating head phenomenon of the young are all bad species, should be removed.
Before the pond is sterilized, the pond must be fully sterilized. The cement pool is soaked in quicklime water for 3 to 7 days, and then added with water for 15 to 30 days to allow the bottom to grow moss. After disinfection, put muddy larvae in the pond for disinfection and detection. If the muddy fishes appear floating heads in 1~4 hours, swimming in the water, or dying, it indicates that cement pool disinfection has not achieved results. Disinfection soaking time should be extended.
Investing in netting and planting grass net cages can not be achieved without water plants. The water grass has the function of shading and attaching the yellow pagoda. Varieties are generally selected water hyacinth and Jiangteng. The excrement of Astragalus is just a fertilizer for aquatic plants. Water plants generally occupy about 70% to 80% of cages or concrete pools.
The trick to seedlings and seedlings is to look at the weather. Should pay attention to weather changes 5 to 7 days in advance to ensure that the next seedling is sunny; water temperature is stable at 25 degrees Celsius; temperature difference between day and night does not exceed 5 degrees; the maximum water temperature does not exceed 35 degrees; To reach these conditions can be seedlings.
It is critical for the growth and survival of Astragalus after domestication under large and small seedlings. Under the seedlings for 3 to 5 days, timely treatment will be given to those who do not eat or have small openings. Tamed seedlings can be given two to three days before the seedlings, and no bait should be given before feeding. The feed can be made up of feeds such as aphids, cockroaches and snails.
In the process of domestication, it is best to be able to do three things: one is to listen to whether the cricket is eating evenly or not; the other is to look at the jaundice that eats in the mouth is more or less; the third is to observe and observe the amount of the remaining bait in the morning, and if there is jaundice Irregularities and whether or not the astragalus out of water plants during the day.
