CATDOLL : CATDOLL: How many kilograms of seeds are needed to plant one acre of golden cicada seedlings (How many kilograms of seeds are needed to plant one acre of golden cicada seedlings)

1. What are the conditions for planting cicada seeds?

Some conditions for growing golden cicada

It is necessary to plant some tree species with vigorous growth and well-developed root systems. The planting depth of golden cicada is basically about 30 cm to 50 cm. The soil needs to be fertile and pollution-free, and it should not be too dry. Of course, there should be no water accumulation.

The planting time is generally from May to July every year. The method is to plant about one meter away from the base of the trunk, and then dig some regular ditches, the main purpose of which is for later excavation.

2. How many years does it take for cicadas to bloom?

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.

3. How many eggs are there in one gram of cicada?

There are 6 to 10 eggs in each nest, 20 to 460 eggs in one ovipositor, generally 20 to 200 eggs, and an average of more than 100 eggs. There are 6 to 100 egg holes on each branch. On average, each female insect has more than 500 to 1,000 eggs in its abdomen, with a maximum of 2,500 eggs, a minimum of 200 eggs, and an average of about 1,000 eggs. In this sense, female cicadas are really prolific mothers. If they are properly raised and managed, they can produce hundreds of young cicadas.

Adult egg-laying usually starts in late June, with the peak period from July to late August and the end of egg-laying from early September to early October. All of them die after laying eggs in November, so no live adults will be seen in December.

Adults like to lay eggs in the woody pith of tender branches about 5 mm thick grown in the current year. The egg nests are arranged in a very regular pattern, one after another, mostly in single rows but also in double rows, in a straight line, with a few curved or spirally arranged.

4. Can cicadas be raised on Zanthoxylum bungeanum trees?

It is feasible to raise cicada monkeys in a pepper garden, but it is not recommended. Because the root system of the pepper tree is not very developed, the juice contained in its roots is not enough for the cicada monkeys to grow. It is also easy to put the pepper tree at risk of death, resulting in a reduction in the production of the pepper garden.

When we usually raise cicada monkeys, the most important factor to consider is whether the root system of the tree is well developed. Although as long as the tree has roots, cicada monkeys can be raised. However, if the tree dies, the cicada monkey will have no source of nutrition and will die.

At present, the trees for breeding cicada monkeys are generally poplars, elms, willows, apple trees, pear trees, etc. The root systems of the above trees are relatively developed, and when cicada monkeys suck the sap from the roots, the impact on the trees is not very large.

5. How long does it take to harvest cicada seeds?

Cicada seeds can be harvested after three years. Cicadas are also called cicada monkeys. They live in the soil. Generally, they come out of the soil in places with trees every three years. They come out at night and climb up the trees. They begin to transform around ten o'clock and become cicada monkeys. Female cicada monkeys lay seeds on trees, usually on dry branches. When the branches fall to the ground, the cicada seeds fall down, and after three years, they become cicadas.

6. How many eggs can a cicada lay at one time?

They can lay as many as 300 to 400 eggs at a time, and some can even lay as many as 700 eggs.

Each hole has 5 to 15 holes, with an average of 10 holes. Cicadas usually drill 30 to 40 holes when laying eggs, so they lay 300 to 400 eggs at a time. The cicada that has laid the most eggs at a time can lay up to 700 eggs. Cicadas lay eggs on thin dry branches. The thin branches that cicadas lay eggs on are generally selected to be nearly vertical, and then pierced into them, just like using the tip of a pin to diagonally insert it into the branch from top to bottom, and lay the eggs inside, with the distance between the pierced holes being almost equal.

7. How many cicada trees should be planted per acre of land?

Use about 25 grams of cicada seedlings per acre of land.

The breeding of cicadas requires planting trees on the land. If you own the land, you can save about one-third of the cost.

Golden cicadas need to suck the roots of trees to grow, so they need trees. You can plant dozens of poplars or fruit trees per acre. Each seedling costs 1-2 yuan, and fruit trees cost about 10 yuan. The amount of seedlings per acre should be determined based on the conditions of the seedlings and the forest land. The yield of golden cicadas is also based on the seedlings and forest land.

8. Cicada seeds?

To put it simply, the seeds of cicadas are the eggs laid by male and female cicadas after mating.

Cicadas lay their eggs on the young and tender branches at the top of trees. While laying eggs, they will use their sharp ovipositors to injure the branches, which will eventually dry up and die. This makes them easier to find and collect.

Therefore, the seeds of the golden cicada can be collected artificially.
