In aquaculture, different aphid species should be selected according to the different requirements of the aphid species in order to receive the expected aquaculture benefits. Introduce several different uses of wolfberry: Suitable for the cultivation of Chinese herbal medicines for the breeding of quail species is mainly ginseng hair ring, also known as wide ground dragon. The species is relatively large, with a length of 120 mm to 400 mm, a diameter of 6 mm to 12 mm, a purple-purple back, a deeper color on the back, and a slightly heavier bristly ring. It is a southern climate and has fertile soil. The manure varieties used for manure-producing farmland mainly include white-stemmed ring hairs, which are 80 to 150 mm in length, 2.5 to 5 mm in diameter, gray or maroon in the back, pale green at the back, and no bristles in the ventral surface. And live in fertile vegetable fields, sweet potato fields, loose soil, manure production, fertilizer field effect is good. As a representative of aquatic feed bait species Hubei ring hairpin. The variety is 70 mm to 220 mm long, 3 mm to 6 mm in diameter, and the body is green grass with a midline purple green or dark green. A red back blood vessel is common, and the ventral surface is gray. The tail cavity often has navy blue fluorescence. The ring zone has three sections, yellowish brown or brown-yellow, hi humid environment, it is better to live in the soil with high humidity in pools, ponds and rivers. It can survive in the water for a long time without polluting the water. This type of oak is mainly used in forestry. It has a length of 90 mm to 250 mm, a diameter of 5 mm to 10 mm, a back surface of gray, grayish green or grayish yellow, and a back centerline of grayish gray. It enjoys living underground in forests, grass and flower gardens. Fertilizer field. The production of quail meat and worms is a kind of genus of love, and the more common is the genius of love. There are 80 to 110 links in the whole body, and the annulus is in sections 25 to 33. From the beginning of the 4th to the 5th, the back and side of the orange or red chestnut, internode gap is colorless, the appearance of a clear stripe, the tail on both sides of the ginger, the older and deeper, flat body and tail slightly into a hook, suitable for many of our country Regional farming, like to eat garbage and livestock manure. Site selection and preparation of feeds are as follows: Farms should be selected for shady, moist and quiet places. Requires feeding places to be easy for heatstroke, heat preservation, good drainage, ventilation, darkness, and invincibility. Old wooden boxes, pots, pots, etc. can also be used for indoor feeding. Cows, pigs, horses, chickens, feces and garbage, peels, leaves, etc., can cultivate oysters, but they must first be decomposed by fermentation to decompose them so that they are acid-free, odorless, and have no bad smell. The feed can use cow dung (or swine manure) 70%, slag fertilizer (or grass) 20%, chicken dung 10%, mixing and stacking fermentation for 10 days, mix and stir once, and then after a week, the feed becomes dark brown, loose texture, No stickiness, no odor can be used. It is also possible to use all of the pig manure or cow dung separately for fermentation. For the first time of feeding, first put a 10 cm to 30 cm thick base material (ie fermented delirium alfalfa feed) inside the rearing container, and then dig from top to bottom on the side of the rearing container to a width of 3 cm to 6 cm. In this case, add soil from below 33 cm from the ground. As long as the crickets are placed on the mud belt and sprinkled with water, the crickets will soon penetrate the soil. If the base material is not suitable for the requirements of earthworms, it will survive in the mud belt and only stick the head into the base material when it is feeding. If the base material is suitable for concrete, it will soon penetrate into the base material. After the base material is consumed, the feed needs to be fed, and the bulk feed method is generally adopted. When feeding, put the old material on the feed surface together with the side of the feeding surface, and then add the fermented feed on the blank surface. After 1 day to 2 days, the old hoppers of the old material piles have entered the fresh feed heap, and then the old feed (slug) was removed. The maggots and eggs were separated. There were a lot of follicles in the old materials, which were hatched after collection. .蚯蚓 Common disease prevention 蚯蚓 All or part of the quail is swiftly licked, and the back also discharges yellow or grass colored body fluids, which are dead in piles. This is the newly added feed containing toxins or toxic gases. Should quickly reduce the material bed, eliminate toxic feed, hook loose material bed, add manure adsorption of toxic gases, so that dive to the ground to rest, in order to slowly adapt. The corpus callosum is partially scorched, with one end shrinking or one end swelling and dying. The undead crickets refuse to eat, and there is a feeling of fear and trembling. Obvious weight loss occurs due to protein poisoning caused by improper feeding method. After discovering the problem, clean up the unsuitable feed, spray water, and loosen the material bed in order to detoxify. Feed contains a lot of starch, carbohydrates, or salt is too high, the bacterial effect easily lead to acidification, causing stomach hyperacidity, so that the body appears sickle nodules, ring with red swelling, the body becomes thicker and shorter, the body secretes Liquid increased, crawling in the breeding bed circle, or drilled to the bottom of the bed can not eat it, and finally the body turned white and died, and some cases of sudden death before the emergence of body segmentation phenomenon. The prevention and control method is to open the cover, allow the trampoline ventilation, spray soda, gypsum powder and neutralize. If the humidity of the trampoline is too high, and the pH of the feed is too high, the edema of the carcass will swell, and it will be in a daze and desperately crawling out. The back hole will emit body fluids and die of food. It even caused the pods to break, or the new pods were not able to close their mouths and the rot was bad. In this case, you can take a ditching method to clean the surface of the clams to another pool, add calcium phosphate powder or vinegar residue, alcohol residue in the original feed and reuse it after a period of time. Environmental Control In a lively environment, there must be enough fresh air. If indoor breeding should be used to open doors and windows, it is required that the feed has good ventilation so as to ensure that the metabolism of the earthworms is strong.蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓. The moisture content of the feed should be about 70%. The upper layer should be squeezed by hand. There should be dripping water between the fingers. The bottom layer requires 1 cm to 2 cm of water. Every morning and evening in summer, watering should be done once a day, in winter every 3 days to 5 days, watering once, and the surface of feed is covered with rice straw to keep warm and moisture. The pH of the feed should be controlled at pH 5.5-7.8. A sour environment can lead to escape or death. Feed should not be mixed with human waste, chemical fertilizers and pesticides and other harmful substances. Pay attention to anti-virus, anti-hazard, and regular removal of earthworm feces. Generally speaking, the activity temperature of limulus is 5 °C ~ 30 °C, and the activity below 10 °C is dull, and the temperature below 5 °C is in a dormant state. Below 0 °C, it will be frozen to death. Therefore, winter should pay attention to warming and heat preservation. Indoor breeding, in winter, strict doors and windows should be blocked to prevent air leakage. Furnaces, fire walls, heating, and other warming measures can also be used. Open-air breeding, winter can be used to move into the cellar, thicken the breeding layer, the use of fermented material heat and other measures to solve the problem of heating, heat preservation. Move the earthworms into the cellar and keep the temperature above 10°C. Thickening the culture layer to 40 cm to 50 cm, covering the weeds above the feed, and then covering the plastic film, is also a practical measure to increase the temperature. The practice of using heat from fermented material is to lay a layer of fresh horse dung at a depth of 20 cm on the bottom of the breeding bed, or to mix fresh chicken manure with a fecal content of about 50%. Membranes and bait are placed on the membrane. How to let the high-yield larvae feed in different stages according to the individual's development stage to give different aquaculture management, is the key to whether the artificial breeding can achieve high yield. The traditional “multi-generational†polyculture method can not be used for harvesting and utilization. It is beyond the best harvesting time to harvest, it is too late to harvest, waste of food and breeding equipment; When harvesting, the output is reduced, and manual sorting increases labor intensity. For artificial breeding, specialized breeding ponds and production ponds must be established. In addition to feeding twice a month, the thin ground feed shall be fed three times or four times in addition to earthworm excrement, earthworms, or inverted feeding beds. Each feeding thickness shall be 15cm to 20cm, and the bait shall be kept fresh and breathable at all times. ecosystem. Timely harvesting of the past data shows that the harvest will be conducted 3 times to 5 times a year. However, in production, it was found that in the case of adequate feed, the intensive period of growth and reproduction of cockroaches (before and after sexual maturation, marked by the presence of carcasses) is implemented in short-term (usually 1 month is appropriate) high-density culture, and Increasing the number of harvests, adjusting and reducing the population density in time, and maintaining the dynamic balance between the amount of growth and harvest are the key to seizing the high yield of alfalfa. The rotation update through the continuous updating of the species and the cyclic rotation of the culture bed not only ensured the robust population, but also avoided the natural decline of the population formed by long-term breeding of the same flock in the same bed. The species should be updated every three or four months. Breeding management, breeding, breeding, breeding, breeding, early larvae, late larvae and adult pupa. Management requirements for different periods are as follows: (1) Species management. The breeding density should be controlled at 2 kg to 2.5 kg per square meter or 10,000 to 15,000 per square meter. The earthworm excrement should be removed every six or seven days. The harvested earthworms should be put into the hatching bed for moist incubation, and at the same time the overturning seedlings should be planted. Trampoline feeding with lateral feeding method to improve the ecological conditions of the breeding bed to facilitate breeding. (2) Management of hatchery beds. The thickness of hatching base should be 10 cm to 15 cm. The hatchery should be kept finely crushed and moist, and 50,000 to 60,000 can be hatched per square meter. The incubation base is loosened once or twice a month with iron fork to facilitate ventilation. Survive with pups. (3) Pre-school management. When most of the incubating bases are to be excreted, excrement should be promptly removed, and feeds should be added with the next vote and the bed should be expanded in time to reduce the calf density. (4) Management of late cubs and adult cubs. The late larvae grow rapidly. To increase the frequency of removing fecal feeds, feed them in the next batch and expand the beds in time; when sexual maturity enters the breeding period, the pupa production and calving advantages must be used, and the breeding density should be reduced or timely. Harvest and use, or replace the old species. The optimum density for the control of aquaculture density and aquaculture is from 2.8 kg to 3.1 kg per square meter or 20,000 per square meter. Within this range, there are few seeds and high yields. The breeding density of early calves can be slightly greater than 30,000 per square metre or 2.5 kilograms per square meter; the rearing larvae to adult pupa breeding density can be gradually reduced to about 20,000 per square meter. Density control should be combined with rotation update. The species of boring bed, hatching bed, preliminarily young bed, and late baby bed should be constructed with an area ratio of 1:1:2:4. Combined with the expansion of the bed, the control density can be achieved. The request.
