Carrot is a kind of vegetable which is rich in nutrition and easy to process. The raw materials are bright red, the section yellow core is small, and the luster is not damaged. Processing should be selected one by one, cut off the non-edible parts, wash 2 to 3 times, according to the requirements of cutting into various shapes, such as block, sheet, stripe, dice, round pattern, stripe pattern, etc. the remaining material is generally processed into dice. The products used for export should be removed according to the requirements of merchants, and the peeling machine can be used for mass production. The processed products are blanched for 1-3 minutes in the hot water of 100 C in the basket. The blanching degree should be strictly controlled. If the blanching is excessive, the products will become soft and discolored, which will affect the quality of the products. After blanching, chill to below 10 C, drain on the vibrating drainer, freeze in the quick freezing device for 10 minutes, and pack quantitatively and refrigerate.

First, there are many kinds of locust farming methods that are suitable for farming methods. To obtain high yields, it is advisable to use the pool culture: Available vacant houses, bricks with a width of 100cm and 100cm in width indoors, and several pools with a height of 30cm. The bricks are paved or the cement is smoothed, and the walls of the pool are also smoothed with a wiping cement. Each pool is covered with a tight wood cover, and the screens are allowed to breathe. Cascade feeding: Indoors are made of concrete prefabricated panels. Each pool area is about 1 square meter, and the depth is 30 centimeters. The reliable wall stacking stacks 3 to 5 layers, which can make full use of the indoor space, increase the amount of culture, and increase the room temperature in the winter, which is conducive to the growth and development of earthworms.
Second, the preparation of a good breeding ground Aphids are insects living in the soil, daytime inhabited soil layer, nighttime in the topsoil foraging. Requirements of loose texture, fertility, dry moisture moderate (grasping into a group is appropriate) farming soil. Method of preparation: Use vegetable garden soil, garbage soil or ditch mud, and incorporate 20% to 30% of fermented chicken manure, pig manure, horse dung, etc., mix and evenly mix nutrient-rich feeding soil after crushing. Before exposure to the pool in the sun for 1 to 2 days to kill bacteria, pests, and then sieved to remove debris and stones. The thickness of the terrarium kept in the pool is 7 to 10 cm for 1-4 months old nymphs and 15-20 cm for 5-month-old nymphs.
Third, the feeding of nutrient-rich feed mites is omnivorous insects, which can be divided into three categories under artificial breeding conditions:
Concentrates, including brans, bean cakes, broken rice, corn flour, etc.;
Animal feed, including slaughtered leftovers such as poultry, livestock, fish, etc., or residues left in the restaurant;
Green fodder: including the leaves of vegetables, beans, potatoes, melons, flowers, fruits, peels, preserved fruits and other clean and fresh products.
Nutritional feed preparation:
No. I, corn flour 1000 grams, 200 grams of bean cake, bone meal 100 grams, 500 grams of wheat bran, add appropriate amount of water and mix well, to grasp into a group, loose the hand that is appropriate, should be followed by feeding;
No. II, 500 grams of wheat bran, 450 grams of milk powder, 50 grams of dried baker's yeast, 50 grams of agar, 3.5 grams of white sugar, 100 grams of dried vegetable powder, and 5 grams of ascorbic acid. When the agar is boiled with water and cooled to 40°C, add wheat bran, milk powder, yeast, sugar, dried vegetable leaf powder, and finally add ascorbic acid and mix well to make a block, dry it at a temperature of 50-55°C, and crush it when feeding. Into bean size;
III, agar 3.5 g, vitamin 2.7 g, glucose 5.5 g, beer yeast 2.2 g, casein 5.5 g, cholesterol 0.2 g, corn flour 3.6 g, water 125 ml, the above raw materials were poured into the flask, the high pressure Disinfect 25 minutes later, use a cotton swab to mouth, use the good feed will be placed in a petri dish, into the feed pot for 1 to 2 months of age nymphs edible.
Feeding nutritious feed can promote the growth and development of earthworms, shorten farming time, and increase yield. When feeding feed, it is necessary to do both wet and dry phase, concentrate and light, and more than green, coarse and fine, with the principle of blue, and feeding according to different insect ages and insect stages. 1 to 3 months of age nymphs should be fed No. III feed or wheat bran mixed chopped melon flowers, tender vegetables leaves, feeding should be small meals, add less. 4-7 months of nymph activity gradually increased, food intake increased, feed ratio can increase the proportion of green feed, species should be diversified to ensure comprehensive nutrition, feed protein content of not less than 16%, can add 1% edible oil, this time can be cast Feed No. I and No. II feeds, green feed to dry the water before feeding, usually 1 or 2 times a day, when the temperature is low in spring and autumn every 2 to 3 days fed once. 8-11 months old nymphs are fed the same diet as mid-aged nymphs, but protein content should be increased. Adult stage, has entered the breeding period, feeding feed should be based on concentrate feed, supplemented by green feed, protein content should reach 22% or more, increase the proportion of edible oil, bone meal, feeding time is in principle every evening. All in all, the feed must be fed regularly, quantitatively, set quality, and fixed point.
Fourth, the appropriate breeding density appropriate breeding density is an important measure to obtain high yield, should be determined according to different worm age. Under normal circumstances, the density of culture ponds and stands per square meter is: 1 to 3 months of age, 70,000 to 90,000 nymphs (weighing about 450 to 900 grams), and 4 to 7 months of nymphs, 25,000 to 35,000 (weighing about 2,250 grams). 9 to 9 months old nymphs 9000 to 18,000 (weight about 2250 grams), nymphs above 10 months old 2700 to 4500 (weighing about 2250 grams), adult 1800 to 2250 (weighs about 4500 grams).
V. Scientific Management Conscientiously doing a good job in management of grasshopper culture is the key to improving hatching rate, survival rate, promoting growth and development, and increasing production. The main management measures are: stand-up culture, that is, egg sheaths produced in different time, batch hatching and separate pool management, which is convenient for feeding, adding materials, and easy to manage. Generally divided into four blocks according to the size of the body: the sesame block (1 to 2 months of age nymphs), soybean blocks (3 to 4 months of age nymphs), broad bean block (5 to 6 months of age nymphs), thumb block (adult). Divided into different pools to support the pool. Adult females in the adult pond lay their eggs 8 to 10 days after mating, and spawning seasons from June to September. Earthworms have the habit of eating eggs. After laying eggs, the laid egg sheaths should be separated and hatched. The pond is allowed to hatch on its own. Usually, the oviduct is taken every 15 days. The adults are first screened out with a 2 mesh screen, and then the egg sheath is screened out with a 6-mesh sieve. The eggs are hatched in batches in different periods and hatched. Soil regulation, ground maggots in the cultivation period should be adjusted according to different ages of a good culture of soil moisture and thickness, so as to meet the needs of growth and development. 1 to 4 months old nymphs cultured soil thickness of about 6 cm, the water content of 20%; 5 to 7 months old nymphs cultured soil shop thickness of 12 to 15 cm, moisture content of about 12%; more than 8 months old nymphs and production Eggs were cultured in 15 to 17 cm thick soils with a water content of about 13%. In addition, the summer should be thin, winter should be thick; temperature and humidity management, earthworm is a variable temperature animal, growth and development and reproduction of other life activities affected by the outside world, in particular, temperature and humidity have a greater impact. Normal room temperature maintained at 15 ~ 35 °C, normal growth and development. Summer (July-September) is the annual growth and development of earthworms. It is also a high-temperature, high-humidity period. When the room temperature exceeds 35°C, doors and windows should be opened to allow air to circulate, reduce the temperature and humidity, and allow indoor ice. The block cools and releases lime to absorb moisture in the room. After the fall, the weather is dry, the relative humidity of the air drops, affecting the indoor air and the humidity of the cultured soil, and the growth and development of the earthworm is unfavorable. The indoor and farming soils should be sprayed with fresh water to increase the humidity, and at the same time, the tender vegetable leaves rich in liquid juice should be fed. Melon flowers, to supplement the water loss in the locust body, to prevent a large number of deaths. In winter, the temperature will drop. We must do a good job of insulation, thicken the cultured soil properly, cover the pool with straw or hay, and close the doors and windows.
Sixth, warming cultured locusts have winter hibernation habits in winter and low temperatures, and it can take up to 5 months. Therefore, it takes 2 to 3 years for the growth and development of the locusts to complete one generation under natural environmental conditions. If the artificial control of temperature and humidity conditions, and to improve its nutritional conditions, break its hibernation, accelerate its growth and reproduction, it can shorten the time it takes to complete a generation, from the growth cycle shortened from 24 to 33 months to 11 months This can increase production, reduce costs, and increase the economic benefits of breeding. The method of warming is: cover the entire breeding room with 2 layers of plastic film, and then hang the door and window with a cotton sheet before heating, leaving no space for heat preservation, heating the furnace to be heated outside, and heating Access to the room, or access to electric heating, and increase the indoor temperature. The temperature of the greenhouse is maintained between 25 and 32°C, which is conducive to promoting the growth and development of nymphs and shortening the age of each worm. This will increase production. Warming should start in late November when the temperature drops to 10°C, and from April to May in the second year, observe changes in indoor temperature after warming culture. Room temperature should not exceed 35 °C, too high to reduce temperature; if the temperature is lower than 20 °C to warm up, after heating the indoor air relative humidity will decrease, to frequent 30 °C warm water spray. It should also be noted that when the temperature is high, the earthworm is active and the body consumes large amounts of water. Therefore, the amount of green feed should be appropriately increased to supplement the body's moisture.
VII. Diseases and natural enemies The most common hazards of controlling locusts are severe. Diseases and natural enemies that cause a large number of deaths are:
Green mold: The belly of the diseased body is dark green, with spots, sagging tentacles, a foot contraction, body softness, weakness, sluggish operation, no feeding, and death after crawling out of the ground during the day. The cause is excessive humidity in the raising soil.
Control methods:
1 Remove pests in time, replace the old soil with infected bacteria, and put new soil on it;
2 The larvae were sprayed with 1% formalin solution and the culturing tanks were sterilized, and the water content of the cultured soil was controlled to be about 20%;
3 Stir in 0.1% oxytetracycline or chloramphenicol and feed 3 times.
Aspergillus zygoste: Eggs and nymphs die due to high temperature and humidity in the egg pool.
Control methods:
1 Prepare a good culture soil in the sun and then disinfect it into the pool;
2 The ovicubum screened out when the egg is taken out is mixed with 1 part of 3% bleaching powder and 9 parts of lime, and is sterilized for 10 to 20 minutes. The egg sheath is screened and hatched in the hatching pond.
Bacterial diseases: The worms and worms are bloated, the stools are grayish green, and the actions are slow and the food intake is low. The female adults stop spawning and the worms are black and dull.
Control methods:
A 500-g feed was mixed with 1 tablet and 2 multivitamins (developed into powder) for 2 to 3 days.
Anthraquinones: Whitefly parasitizes on the body of a mantle worm and sucks body fluids, affecting the growth and development of the worms and causing death.
Control methods:
A whitefly is infected from the feedstuff. Therefore, the feed used should be exposed to sunlight or fried and then fed again.
2 Smell bait trapping, during the day with the fried meat, fish, bones, killing, remove once every 2 hours, repeated use of bait;
3 Replace farmed soil.
Gastric wall ulcer disease: Improper feeding of feed, resulting in long-term feeding of earthworms, indigestion. Black spots appeared in the lower part of the belly of the pests, and the stomach wall adhered to the intersegmental membrane. In severe cases, the membranes festered and odor flowed out, resulting in hunger strikes and death.
Control methods:
1Rough, fine, and green feeds should be properly fed and kept fresh;
21,000 grams of feed mix in yeast tablets and the amount of antibiotics and vitamin B;
3 Feeding with alkaline dry feed, using 500 g of fried rice bran and ground smashing baking soda 20 tablets, oxytetracycline 5 tablets, fed in portions;
4 Bogey feed green feed with large water content.
Ant: It is the main natural enemies of earthworms. Often killing locusts and removing feed in groups;
Control methods:
1 Find the ant colony and immediately clear the pond. Block the ants' burrows, and apply a circle of Vaseline or oil belt with a width of 3 to 6 cm around the pool. Sprinkle a small amount of lime powder or chlordane powder around the pool and sprinkle the wet soil around the pool.
2 Use pig bones to lure ants to eat together and concentrate on killing.
Earthworm worms, also called earthworm worms, earth elements, are commonly used Chinese herbal medicines, and have functions such as breaking blood, removing phlegm, removing phlegm, and continuing injury. The medicine is used in formulas and raw materials of many proprietary Chinese medicines, and is a live food bait for special economic animals. In addition, in recent years, living locusts have become dishes on the dining table in some areas, and the demand has soared. They have become hot sellers on the market and the prices have continued to rise. In 2003, the market price was only 25 to 30 yuan per kilogram dry product (the same below), and rose to 40 to 45 yuan in 2004. Just entered 2005 and continued to rise to 55-60 yuan, more than a year time the price increase of up to 100% to 120%. At present, the golden opportunity for the development of locusts in breeding grounds is now being introduced as follows.
