CATDOLL : CATDOLL: How many years does it take for cicadas to grow out of the ground?

1. How many years does it take for cicadas to emerge from the ground?

About a year and a half.

The feeding points are as follows:

1. Breeding site

Cicadas are mainly bred under forests. Their growth needs can be met under various fruit trees and timber trees. There is no need to invest in building sites or houses, and there is no need to purchase other breeding facilities. my country is rich in forest resources, and it is generally difficult to interplant crops under fruit trees and other trees that are more than three years old. Cicada breeding makes use of the space under trees and grows by sucking the sap from the roots. It can be said that this develops breeding without affecting the growth of trees, killing two birds with one stone. The entire breeding process does not require feeding management, epidemic prevention, etc., and does not occupy labor. If the technology and sales of cicada breeding are solved, cicada breeding is a good project for laid-off workers to develop re-employment and for farmers to engage in the tertiary industry.

2. Egg collection

The eggs are collected after the cicadas lay eggs in autumn, usually around the seventh month of the lunar calendar. The cicadas use the small thorns on their tails to pierce the tender branches of one-year-old trees and lay their eggs inside 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.

3. 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.

4. Incubation

The larvae will hatch in about fifteen 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 selected 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. In a plastic pot that is 10 cm long, 40 cm wide and 20 cm high, spread 5 to 10 cm thick fine dry sand on the bottom, place the egg branches in bundles vertically or horizontally on it, and constantly spray mist with a small sprayer to maintain high humidity in the air around the branches of the golden cicada eggs so that excess water droplets are absorbed in the fine sand at the bottom. During the incubation period, the hatching status of the golden cicada eggs should be checked continuously. When a small number of golden cicada larvae are found to be active, the branches and fine sand can be placed in the breeding site for planting.

5. Planting seeds

Dig the 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.

6. Sowing time

Planting time is generally from May to July or from September to October. Dig regular narrow trenches about 10 to 30 cm deep about 1 meter away from the base of the trunk, such as ring, square, triangle, parallel or radial shapes, for the purpose of later digging and harvesting. Cover the soil and compact it after "planting", and keep records of the time, quantity, "planting" trench shape and depth. It should be sunny and frost-proof, with soft, fertile and pollution-free soil; it should not be too dry, nor should it have too high water content or water accumulation, to ensure the normal growth and development of the host plant root system, and the young plants should be tender, developed and juicy. In winter, wheat straw, rice straw, corn straw, etc. should be covered in the planting area to maintain the ground temperature.

7. Harvest

If there are trees, wrap a circle of transparent tape at one meter to prevent the cicadas from climbing high to metamorphose. Cicadas become adults 15-18 months from the date of sowing.

8. Collection

Cicada eggs are mainly made of wax strips, and 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 advances the original growth period of 3-15 years to 18 months, the incubation period is increased from the original one year to about 35 days, and the survival rate is increased from the original 6% to about 30%-60%. Therefore, it is particularly suitable for breeding in rural areas.

2. What is the annual demand for golden cicadas in my country?

Golden cicada is also known as grasshopper cicada, cicada turtle, cicada monkey, etc. The nymph of golden cicada (cicada turtle) has extremely high nutritional value and unique taste. The newly unearthed nymph contains the highest protein, which is a rare high-protein, low-fat wild delicacy. According to the "Chinese Materia Medica", grasshopper cicada has the functions of clearing and strengthening yang, quenching thirst and promoting fluid, protecting lungs and kidneys, resisting baldness and inhibiting cancer. The cicada shell is rich in chitin, isoxanthopterin, erythropterin, adenosine triphosphatase, cough hoarseness, sore throat, urticaria itching, red eyes, tetanus, infantile epilepsy, crying at night, etc. Therefore, some people predict that cicada will become an important green health food in the future. Due to environmental destruction and tree felling, the living environment of grasshopper cicada nymphs has been severely damaged, and the indiscriminate capture by humans has led to a serious depletion of nymph (cicada turtle) resources. In terms of demand, the demand in large cities such as Beijing, Shanghai, and Guangzhou alone is more than 100 tons, the market gap is quite large, and the market price is getting higher and higher. Artificial breeding of cicadas has a bright future. Artificial breeding of cicadas has the following advantages: (1) Wide range of resources. There are many poplars, fruit trees and other trees in rural areas, and the land resources are rich. (2) Cicada eggs can be purchased from professional breeding farms or collected by yourself. (3) The breeding time is shortened. The breeding time for indoor ponds and plastic greenhouses is 8-10 months, and the breeding time for eggs in the field is 1.5 years after natural breeding. (4) There is no need for feeding and management. Cicada eggs will suck the juice of tree roots when they are buried in the soil. (5) High efficiency. There are 2,000 eggs per square meter, and each egg costs 0.1-0.2 yuan. The income per square meter is 200-400 yuan. If the breeding does not affect the growth of crops on the ground, only 50 square meters of cultivation are needed per mu, and the income will be more than 10,000 yuan. (6) The product is popular. Restaurants, hotels, and refrigerated food factories will come to our door to order goods. Our center provides cicada eggs and frozen cicadas all year round. The purchase volume is large and the price is favorable.

3. Can cicadas be raised in Jilin?

You can breed cicadas in Jilin. Although I don't breed them myself, my brother has been breeding cicadas for more than two years. I suggest you plant an orchard on the ground and breed cicadas below the orchard, so that you can have a good harvest. You can search for the Hubei Xiangyang Cicada Breeding Base . They have many years of breeding experience. My brother bought the cicada eggs from there. The boss of their base is a veteran. My brother and I have been there. The service attitude is very good. You can go and find out for yourself.
