Ensuring adequate and high-quality feed is a key factor in the rapid and high-yield production of Astragalus. Since the Astragalus membranaceus is an omnivorous fish dominated by animal feed, its feed sources are extensive and relatively easy to obtain. Therefore, Astragalus breeders can use existing resources to collect and cultivate live feeds.
I. Introduction of Breeding Breeds
Full use of raw materials such as cow dung, domestic waste, etc. Breeding clams, with varieties such as Daping No. 2, Beixing No. 2 and Aiko Aisheng, etc. are preferred. Aquaculture waste can be used in abandoned barrels and tubs, and a small 2 cm diameter drill is drilled at the bottom. Holes, and covered with gauze, to facilitate ventilation, drainage; can also be digging pits in well-flooded areas or feeding with brick pools.
Second, to cultivate fly lice
You can make your own species fly cages, buy good breeds of domestic fly species at fly maggot farms, and produce sterile fly maggots, which can also be launched by local methods, grind them with 0.5 kg soybeans, and pour into a water tank that can hold 40-50 kg of water. Add 2.5 kg of fresh pig blood and 10 kg of water and mix well. After one week, grow maggots.
Three sets of raising snails
Several bamboo cages were hung around the rearing ponds, and the nets were 4-6 meshes. A certain number of species of snails were enclosed in cages, and 2/3 of the screw cages were immersed in water. Most of the breeding young snails crawled out of the cages. , can eat for the Astragalus. Can also go to drains, rice fields, snails, shells, shreds and chops.
Fourth, light trapping
Lift up and down two black lights above each pond. The upper one should be suspended to attract more distant insect moths. The lower one is lower, preferably 20 centimeters from the surface of Dianchi Lake. When the sky is dark, turn on the high-altitude black light. When the moth is found around the high-altitude light, turn on the black light and turn off the high light. At this time, the high-flying moth will quickly dive down and gather around the surface light. At the same time, due to the reflection of electric lights in the water, many moths will flush in and bury their stomachs. When there are few moths on the pond, turn on the high-altitude black light to lure. Repeatedly, this method can be used in summer and autumn to obtain 30% jaundice feed.
V. Collection of leeches
Dig a shallow pool in the place where there is a water outlet. There should be humus in the bottom of the pool, keep the depth of 5-6 cm, apply some fermented organic fertilizer regularly, and the leeches will multiply.
