Yuan also known as locusts, locusts, distributed in vast areas of our country. Tuyuan is a rare cool Chinese medicine, which can be deflated, destroyed, meridian, and damaged. The development of the earth yuan breeding, small investment, use less labor, get rich quickly, is a good income for rural families to keep the door. In response to the request of Mr. Liu of Xuchang City, Mr. Li of Yanshi City and the reader of the mobile phone number 132XXXX6619, we invited the associate researcher of the Institute of Biology of the Provincial Academy of Sciences to write an article to answer the questions concerning the breeding, management and prevention of common diseases of the Yuanyuan.
Feed Management Technology
First, feeding method can be used for raising or pot raising, but also can be used to raise the pool. The indoor temperature of the breeding room should always be maintained at about 30°C, so that it can be marketed in 9 months; if it is kept at outdoor natural temperature, it takes about 30 months before it can be listed.
Second, feeding and management (a) feeding soil preparation. Using 30% of the loam in the field, 70% of the fermented sawdust was mixed and exposed to sunlight. It is also possible to use 30% of plant ash and 70% of field soil. (b) Temperature and humidity. The suitable temperature and humidity for soil growth: indoor temperature 30°C ~ 32°C, humidity 70% ~ 80%, raising soil temperature 28°C ~ 30°C, humidity 15% ~ 20%. (c) Feed. 1. Fine feed. Botanical feedstuffs include foodstuffs, glutinous rice bran, rice bran, wheat bran, and animal feedstuffs such as fish meal, silkworm meal, and bone meal. 2. Green feed. Including various vegetables, fresh wild herbs, tender pasture, tender leaves, crops and young leaves. 3. Juicy feed. Including melons, fruits, pears, peaches, carrots, white radishes, potatoes and other more water-rich feed. Reference feed formula: corn flour 50%, wheat bran 25%, soybean meal 10%, bone meal 5%, fish meal 2%, leaf meal 8%. (d) Management. 1. Environmental control. The air in the breeding room should be fresh, and the ventilation and ventilation should be done frequently during the winter seasoning. However, the temperature difference should not exceed 5°C. Feeding soil thickness: larvae 7 to 15 cm, adults 20 to 25 cm. The soil moisture is 15% to 18%. 2. Breeding density per square meter. There are 80,000 to 200,000 sesame seeds, 80,000 to 100,000 mung bean cultivars, 30,000 to 40,000 soy beans, 14,000 to 20,000 faba beans, and 8,000 to 10,000 adults. There are 0,400 to 50,000 females.
Third, harvesting and early processing of males matured early, when their wing buds have just grown out of time to make a selection, pick out the individual large, good color left to do the species, the excess water with hot water after the death of dried medicine. The female worms were sifted 9 to 11 times, and all of them were screened out, and the individual was selected to be large and the color was good. The seeds were dried after being sacrificed. Do not harvest on cloudy days.
Prevention and treatment of ossein sheath rot
The etiology caused by the fungus. Since the container holding the egg sheath is not clean, when the humidity is too high, the mold grows and the egg sheath becomes moldy.
Symptoms of the moldy oocyst flow out of the white liquid. Observed under a magnifying glass can be seen white filaments, moldy egg sheath smell.
Prevention and cure 1. The collected soil must be exposed to sunlight for disinfection.
2. Once every 5 to 7 days, collect the egg sheath. The collected egg sheath is removed, washed and dried. Then, 1 part of bleaching powder and 9 parts of lime powder are taken, wrapped in gauze, and sprinkled on the egg sheath. On the top, the powder was sieved after 30 minutes and the egg sheath was preserved.
How to prevent green mold
The enthusiasm of the environment is too high, the green mold is breeding rapidly, and the soil element is caused by the infection of green mold.
Symptoms The soil of the affected soil element is dark green, spotted, and the limbs are contracting and the antennae are sagging. No earth is eaten.
When the air humidity is high, it is necessary to keep the soil dry and the moisture content of the feed should be less. Frequent removal of leftover feeds and frequent cleaning and disinfection of the feed trays are required.
The treatment selected the affected soil yuan, used 0.5% formalin to disinfect the parasites, screened the healthy pests in the disease-feeding pond, and used 3% formalin to disinfect the breeding ponds; Stir the diet with antibiotics and mix 1 gram of chlortetracycline or oxytetracycline powder per kilogram of feed.
Prevention of bulging disease
In the early spring and late fall seasons of the cause, after the Tuen had eaten a lot of food, the temperature suddenly turned low, and its metabolic capacity decreased, causing indigestion.
Symptoms The affected soil yuan has swollen abdomen, inconvenient crawling, loss of appetite or waste, diarrhea, faeces green, and loss of body luster.
Prevent warming when the temperature suddenly drops. The amount of food to be fed varies depending on the weather. When the temperature is high, it is more likely to be cast, and when the temperature is low, it is less. Less feed green feed on rainy days. Add 0.02% oxytetracycline or sulfamethoxime to earth element feed when temperature is low.
Treating the affected soil yuan group, feeding 2 pepsin, 2 berberine, and 2 rhubarb soda per kilogram of feed.
Reproductive characteristics and hatching techniques
Terrestrial insects are incompletely metamorphic insects. They have experienced three stages of eggs, nymphs, and adults throughout their lives. They are one stage shorter than fully metamorphic insects. The nymphs once per tick, the larvae are 1 year old, and the body weight and body length increase by 1 grade, and the reproductive growth and development advance one stage. After seven to nine moultings, the male larvae matured after 270-320 days. Female nymphs developed and matured after 9- to 11-fold moulting and 450-500 days.
Terrestrial sex for the sexual reproduction, oviparous. A male terrestrial male can mate with 3 to 5 females during his lifetime, and after the mating, the male terrestrial wing breaks, and one month later, he or she will continue to die. The female terrestrial females begin spawning about 7 days after mating. The mating season is summer and autumn, and the mating rate is highest at 25°C-32°C. During the mating season, the terrestrial earth occupies 40% of the total adult population. At natural temperatures, from October to October, spawning period, and from June to September, spawning seasons. A healthy female adult produces 70-100 egg yolks. The hatching rate of the egg sheath is related to the preservation time and temperature, and the incubation time is long and the hatching rate at the time of storage is high. The larvae can still be hatched when eggs are stored for 4 months at 12°C-15°C, but they cannot be stored at temperatures above 20°C for a long period of time.
Incubator containers with plastic pots, tubs, plastic buckets, etc. can be used before disinfection with 0.2% potassium permanganate solution. The incubating soil is made up of 30% field loam soil and 70% sawdust. Sawdust must be taken from the fermented hardwood trees. Before use, incubate the incubator soil in the sun for more than 3 days to kill the eggs, mold, etc., and then use 0.1% potassium permanganate solution spray disinfection, humidity of about 20%, that can hold into a group, let go Spread; egg sheath soaked with 0.2% potassium permanganate solution for 3 to 5 minutes. Then, the egg sheath and hatching soil were mixed in a ratio of 1:1, placed in a container, and covered with 4 layers of wet gauze. Wet gauze is soaked in time and removes excess moisture to facilitate ventilation. After the incubator soil is dried, the ovum sheath is screened out, water is sprayed on the incubating soil, and the mixture is mixed with the oocyst and then covered with wet gauze. The temperature of the incubation chamber is maintained at about 30°C, the humidity of the incubating soil is kept at about 20%, the relative humidity in the room is 70% to 80%, and the nymphs can be hatched after about 40 days.
