CATDOLL : CATDOLL: How many days does the artificially bred golden cicada grow in? (How many days does the artificially bred golden cicada grow in?)

1. What are the precautions for artificially breeding cicadas in Henan?

The cicada's egg branches overwinter with the cicada egg groups on the young branches of the current year or two years old and the nymphs of various ages concentrated on the plant roots in the soil. After planting, it is necessary to manage the environment, feed, breeding objects, etc. to complete the process of the cicada's emergence, adulthood, and egg laying. 1. The growth process of a growth cycle of the cicada: It usually takes 5 to 7 years for the cicada to complete one generation. Artificial breeding of cicadas can shorten the growth cycle to 24-36 months. The cicada egg groups overwinter on the young branches of the current year or two years old and the nymphs of various ages concentrated on the plant roots in the soil. The overwintering eggs begin to hatch in mid-May of the following year. The egg period of wild cicadas is nearly 300 days. After artificial hatching, it only takes about 40 days to complete. After completing the entire life process of the nymph in the soil, the mature nymphs of the cicada emerge from the soil in late June to mid-to-late July, and crawl to the branches of shrubs, stems of weeds, etc., molting and emerging as adults. About 20 days after the emergence of adults, they mate and lay eggs. The adults lay eggs on one- or two-year-old branches with a thickness of 2 to 7 mm. There are 100 to 489 eggs in one oviposition branch. Each female cicada carries more than 500 to 1,000 eggs in her abdomen, with a maximum of 1,500 eggs. They use their piercing-sucking mouthparts to suck the nutrient juice from the young branches of trees for a living. After mating, the female cicada inserts the ovipositor into the wood of the tender branches of the current or two-year-old branches before laying eggs, and then lays the eggs. 2. Management experience after planting: Provide a good environment for cicadas: The "breeding" of cicadas should be 10 to 30 cm, facing the sun and preventing frost, with soft, fertile and pollution-free soil; it should not be too dry, nor should it have too high a water content or water accumulation, to ensure the normal growth and development of the host plant root system, and the young, tender, developed and juicy. Obtaining feed: Choose healthy tree species with well-developed root systems, lush growth, and more juice, such as poplar, elm, willow, tung or various fruit trees in the orchard. Breeding time and hatching method of breeding objects: ① Focus on indoors to promote hatching. Hatching method: In a plastic box 70 cm long, 40 cm wide and 20 cm high, spread 5 to 10 cm thick fine dry sand on the bottom, put the egg branches in bundles vertically or horizontally on it, and constantly spray mist with a small sprayer to maintain high humidity around the branches with eggs, so that excess water droplets are adsorbed in the fine sand at the bottom. In the middle, the hatching of eggs should be checked continuously. When nymphs are found to be active, the branches can be placed in the breeding site together with the fine sand. ② Breeding time is generally from May to July every year. The ground under the host plant tree in the breeding site is about 1 meter away from the base of the trunk. ③ From the egg stage to the growth and development of mature golden cicada nymphs, there are an average of 210 per kilogram. At this time, the body color is brown and the eyes are dark gray. Based on the changes in weight, body color and eye color, the age stage of the nymph's growth and development can be accurately determined.

2. How long does it take to artificially breed cicadas?

Cicada breeding technology Cicada is an oviparous and underground incubated medicinal material with extremely high medicinal value. It has the effects of clearing blood and removing blood stasis, health care, and has a certain therapeutic effect on hypertension. However, the existing cicada has the disadvantages of long growth cycle, low survival rate, and is not suitable for collection. After several years of research and experiments, our company has summarized a set of cicada breeding technology based on the growth habits of cicada.

1. Egg collection: Egg collection is done after the cicada lays eggs in autumn, usually around the seventh month of the lunar calendar. The cicada uses the small thorns on its tail to pierce the tender branches of one year old trees and lay eggs in the branches, mostly on juicy branches such as fruit trees. After laying eggs, the branches will dry up, so most branches with green lower ends and dry tips have cicada eggs.

2. Post-harvest processing: After collecting the branches with cicada eggs, remove the dry leaves, cut off the two ends, and bundle thirty branches into a bundle. Spread a layer of sand on the bottom of a large washing basin, and put the bundled branches upright in the basin. Keep the temperature at 28-34 degrees and the humidity moist. Spray it when it is dry. Use a sprayer to spray the branches until they are thoroughly wet.

3. Hatching: The larvae will hatch in about 15 days. At this time, you will see some larvae crawling up and down on the branches. When about 20% of the larvae have hatched, they should be buried. The burial pit should be in an area with many fine and soft hair roots so that the larvae can absorb nutrients from the roots. It is best to choose a plot where honeysuckle is planted.

4. Sowing: Dig a pit into a strip shape, the depth should be mainly to the hairy roots, and the width should be one shovel. Put the branches with hatched larvae into the pit, and the larvae will hug the plant roots by themselves. Be gentle and slow when returning the soil. Do not step on the soil after returning it, and do not water it to ensure ventilation.

5. Harvesting: If there are trees, wrap them with transparent tape at a distance of one meter to prevent the cicadas from climbing high to metamorphose. Cicadas will become adults 15-18 months after sowing.

6. Tips: Cicada eggs are collected mainly from wax branches and fruit tree branches. Cicada egg larvae feed on the juice of plant roots, so it is best to choose a multi-root area when burying. Each branch contains 100-400 cicada eggs, so 500-800 branches per mu are appropriate to ensure the survival rate. Using this method to grow golden cicadas can advance the original growth period of 3-15 years to 18 months, the incubation period from the original one year to about 35 days, and the survival rate from the original 6% to about 30%-60%. Therefore, it is particularly suitable for breeding in rural areas.

The price of golden cicadas is rising, and they have been served on the tables of restaurants of all sizes. The prospects are promising. The survival rate of golden cicadas planted in this way is high. If the minimum survival rate is 30% per acre, about 100,000 cicadas can survive.

Farming technology

1. Planting trees

Choose healthy tree species with well-developed root systems, lush growth, and more sap, such as poplar, elm, willow, tung or various fruit trees in the orchard. You can also plant honeysuckle and day lily in the breeding area. In addition, intercrop some root and tuber plants, such as potatoes, sweet potatoes, and yams.

You can build a gauze greenhouse and use short trees. The gauze should be more than twice the height of the tree, so that the cicadas can reproduce freely. When selecting seeds, male and female should be one to one.

(II) Branch processing

Collect the egg branches and bundle every 100 branches. Then mix them with 1% washing powder (100 kg of water to 1 kg of washing powder), and soak the bundled branches in the solution for two minutes. After taking them out, rinse them with clean water and stand them upright to dry. After that, spray them with pot ash mixed with water to kill pests and bacteria.

(III) Indoor storage

First, clean the room, use dark fire and smoke to disinfect, kill insects and sterilize. Then pack or box the dried branches and place them on the indoor rack, and make the room ventilated and light-permeable.

4. Indoor incubation

At the end of May in the Gregorian calendar (when the temperature is suitable), you can hatch indoors or in a greenhouse. Place 10-15 cm of dry sand in the indoor or greenhouse, or use a plastic pot in the greenhouse to fill it with 10-15 cm of dry sand. Soak the branches in 20-degree warm water for two minutes, take out 10 bundles and place them on the sand in the indoor or greenhouse. Use 0.1% glucose powder and water to spray the branches with a sprayer to supplement the nutrition of the eggs stored in the dry branches for a long time. The larvae hatched in this way are strong and have a high survival rate. Note: Spray evenly with warm water three times a day, the humidity should not drip down, the temperature should be kept at 26-32 degrees, and the hatching time is 30-35 days.

(V) Planting

At the end of June in the Gregorian calendar, the hatched egg branches are buried for breeding. First, loosen the forest land with a disturber, 60 cm away from the tree and 15 cm deep, to loosen the soil and avoid breaking the tree roots, so that the pests can hide in the 15 cm mature soil layer. When digging trenches for planting, the distance should be about one meter from the tree, and the trench depth should be 35 cm. Sawdust and plant ash should be sprinkled on the bottom of the trench to kill insects and sterilize. Sawdust can promote the growth of larvae. Then put the hatched branches at the bottom of the trench, seal the trench with soil, 2 cm above the ground, do not step on it, and do not water it. After a period of time, you can fertilize, water, and spray the trees.

3. How many times do you need to plant seedlings to raise cicadas?

3-4 times bacteria.

The growth cycle of cicadas is 3-5 years, and the artificial breeding cycle is generally about 280-300 days. To shorten the breeding cycle, the density of trees can be appropriately increased, or constant temperature breeding can be carried out. When breeding cicadas, it is necessary to choose sunny and loose soil plots as breeding sites. The water content of the soil should not be too high or there should be water accumulation. The tree species are suitable to choose willow, elm, poplar and other varieties. The breeding time of cicadas is preferably from May to June. Before placing the egg branches, the soil preparation for the cicada ants should be well prepared.

4. What is the growth cycle and temperature of the cicada?

The growth period of the cicada is three months, and the temperature is 50 degrees.

The main factors for the incubation of cicada eggs are air humidity and temperature. Although we can control the incubation temperature of cicada eggs through the greenhouse effect, we must plant them within a specific period of time. Because the young cicadas (cicada ants) that have just hatched from the cicada eggs are extremely weak and can easily die.

5. What is the growth cycle of the cicada?

Is it a cicada? The eggs can hatch into larvae in 100 days, which is one generation. Generally speaking, the growth cycle of a generation is three to five years. According to records, some generations are five to eight years or even twelve or thirteen years. After the first generation is completed, they crawl out of the ground and transform into the second generation, which is the cicada. The cicada will mate and lay eggs in about 20 days, and then die after laying eggs. The so-called artificial breeding starts with breaking off the branch where the cicada died and placing it in the breeding place for natural hatching, or digging out the first generation of adults that are about to crawl out of the ground in the wild.

6. How many days can the hatched cicada seedlings survive?

It can survive for 18 days. The growth cycle of artificially cultivated cicadas is generally about 3-5 years. The breeding time can be shortened by increasing the density of trees. From the egg stage to the development of mature nymphs, the cicada needs to go through 3 winters and summers underground, which takes about 3 years.

In the first year, it starts to grow from June, its whole body color is milky white and its weight is only about 1 gram. In the second year, its color becomes darker and its weight reaches about 3 grams. In the third year, it matures, its body color turns brown and its weight reaches about 4.5-5 grams.
