What are the main technical points of artificial culture of golden cicada? How much does it cost to invest? How much money can you earn per mu?

Golden cicada is particularly rich in nutrition, golden cicada is regarded as a famous dish in many places, and its meat is delicious. And the golden cicada also has great medicinal value, which directly leads to the rapid rise of the golden cicada breeding project. So what are the main technical points of artificial culture of golden cicada? How much does it cost to invest? How much money can you earn per mu?

What are the main technical points of artificial culture of golden cicada?

1. Egg collection

Egg collection is after the golden cicada lays eggs in autumn, usually around the seventh month of the lunar calendar. The golden cicada spines into the annual twigs with small thorns in its tail, laying eggs into the branches, mostly fruit trees and other succulent branches, and most of the branches will dry up after laying eggs, so most of the green branches at the bottom and dry ends have cicada eggs. The collection of eggs can choose an ideal place with dense cicadas, using fruit branch shears or long poles with hooks at the top to cut off the withered branches of golden cicadas on the tree, tie them into a small bundle of 50-100 pieces, and put them into a plastic bag for use.

In addition to the natural collection of cicada eggs, a screen greenhouse can be established to provide space for adults to lay eggs. You can use the fruit trees in the abandoned orchard to replant the fruit tree seedlings, set up a fence around with cement columns or bamboo sticks, and set up iron wire in the middle, which can be covered with nylon window screen. When the captured adults are put into them to mate and lay eggs, the number of adults can be retained as needed, and there is no need to collect provenances from the wild.

2. Post-harvest treatment

After collecting the branches with cicada eggs, remove the dry leaves, cut off both ends, tie 30 into a bundle, spread a layer of sand at the bottom of the large laundry basin, put the bound branches into the basin, keep the temperature at 28% 34%, keep the humidity at 28%, that is, spray when dry, spray the branches with a sprayer until they are wet.

3. Incubation

The egg-bearing branches collected directly from the wild or in the provenance site were concentrated in the hatchery to promote hatching. Hatching method: spread fine dry sand 5-10 cm thick at the bottom of a plastic box that is 70 cm long, 40 cm wide and 20 cm high, put the egg branches vertically or horizontally on them, and constantly spray fog water with a small sprayer to maintain the high humidity of the air around the egg branches, so that the excess water droplets are absorbed in the fine sand at the bottom. In the middle, the hatching of eggs should be checked constantly, and when nymphs are found, the branches together with fine sand can be placed in the breeding site. The larvae hatched in about 15 days. At this time, you will see some larvae climbing up and down the branches. About 20% of the hatched larvae are buried, choosing areas with fine soft roots so that the larvae can absorb nutrients from the roots, preferably in loose woodlands.

4. Reproductive species

The breeding objects are newly hatched nymphs and eggs close to hatching. The soil quality requires no desertification, no consolidation, no ants, moles, loose wet loam zone, and it is appropriate to choose places with more cicada monkeys last year as sites for burying egg branches.

The breeding time is generally from September to October (biennial eggs) or June to July (current year eggs). In the breeding site, the ground under the host plant tree is about 1 meter away from the base of the trunk, dig a regular narrow trench with a depth of about 30-50 cm, dig the pit into a strip, the depth is mainly dug to the hairy root, and the width is a shovel. Put the branches of the hatched larvae into the pit, and the larvae hold the plant roots by themselves. When returning the soil, it should be light and slow, but fortunately, you can't step on it, and you can't water it to keep it breathable. After breeding, the cover soil is compacted, and the time, quantity, groove shape and depth of breeding are recorded.

5. Supply of high quality feed

Choose healthy tree species with developed roots, luxuriant growth and more juice, such as fast-growing poplar, elm, willow, paulownia or all kinds of fruit trees in the orchard. In addition, we should also ask to make some rhizome plants, such as potatoes, sweet potatoes, yams and so on.

6. Provide good environmental conditions

Grasshopper cicada "breeding" depth of 30-50 cm is appropriate, should be sunny anti-freezing, soil soft, fertile, pollution-free; not too dry, water content can not be too high or the existence of stagnant water phenomenon, to ensure the normal growth and development of host plant roots, tender, developed and succulent. In winter, wheat straw, rice straw and corn straw should be covered in the breeding area to maintain the ground temperature.

7. Culture management

After the cicada eggs are buried in the ground, attention should be paid to drainage and waterlogging in the rainy season. Water white willow, willow or apple trees on dry days. At the same time of watering, it is necessary to apply farm manure to promote luxuriant growth and provide sufficient nutrition for the cicada larva-the young cicada monkey, so as to make the young cicada monkey grow vigorously, increase the individual and increase the yield. It is necessary to strictly guard against the trampling of human and livestock and the infringement of natural enemies such as ants and moles.

8. Harvest

After burying egg branches for 2-3 years, cicadas begin to grow and mature gradually. The harvest time is usually in the Summer Solstice every year, if there is a thorough rain, the fat nymphs one by one, so that they can start to drill out of the ground at 4-5 in the morning, or after the rain clears up, the nymphs dig out of the hole with a pair of jagged forefeet in the wet and soft ground. after climbing out of the ground, do short-term exercise on the ground, and then climb the tree trunk or scaffolding ready to molt. After 2-4 hours, it will molt and become a cicada (cicada). According to this characteristic of the golden cicada, after the Summer Solstice every year, if there is no rain and drought, the breeding site can be artificially watered to lead the cicada to be unearthed. Before the cicadas are unearthed, or before the cicadas mature, tie a smooth plastic film around the trunk 30cm above the ground, so that the cicadas can not continue to crawl up the trees for harvest. You can also use flashlights to find a catch on the ground and trunk under the tree at night. Or catch feathered young cicadas in the trees early in the morning.

Second, how much does it cost to raise golden cicadas? How much money can you earn per mu?

According to 800 eggs per mu, the yield per mu is about 200 jin, and according to the market price of 30 yuan per jin, the income per mu will not be a problem.

In addition, if the semi-natural technique of raising golden cicadas under trees is adopted, the growth cycle of golden cicadas can be shortened from 3 to 5 years to about 24 months, and the yield of golden cicadas can be increased and more benefits can be obtained.
