Culture technology of golden cicada in greenhouse

Golden cicada is not only a very common insect, but also a delicious dish sought after by adults. The golden cicada is particularly rich in nutritional value, and the golden cicada is in short supply in the market, which has created the golden cicada breeding project. The following editor will take you to understand the golden cicada breeding. Friends who want to breed the golden cicada can learn about it with the editor.

Culture technology of golden cicada in greenhouse

1. Select breeding trees

Dwarf fruit trees such as apricot, peach, apple or other dwarf shrubs are good trees for golden cicada breeding. Pay attention to pruning excessively high branches in time to facilitate breeding and management; interplant seedlings of fruit trees in the gaps of trees to increase the branches from which golden cicadas lay eggs; and breed golden cicadas under trees with reference to "culture techniques of golden cicadas".

2. Construction of breeding greenhouse

A breeding greenhouse should be built on the eve of the golden cicada being unearthed, with an area of 1 mu each. In the breeding area around the use of cement columns or bamboo rods to build a fence, the cement column row spacing of 5 meters, the middle with bamboo poles, and then fixed with iron wire, and then covered with nylon window screen. Breeding should choose plots with high dryness and convenient drainage and irrigation, and do not build breeding sheds in low-lying areas where water is easy to store.

3. Seed and pest management and epidemic prevention

After the golden cicada was unearthed, because its adult had a strong phototaxis, in the early stage, the feathered golden cicada entered the greenhouse after the emergence of the adult, and the feathered golden cicada would fly and bump everywhere when caught, resulting in the death of the species, so all the golden cicadas unearthed in the previous week could be captured, and the golden cicada could be naturally feathered and laid eggs after a week. The seed density is about 10000 per mu, and each female and male account for about 50%. Each female golden cicada can lay 500 eggs and 1500 eggs, and each greenhouse can provide about 20 mu of land for golden cicada breeding.

The golden cicada can mate and lay eggs about 20 days after Eclosion. When laying eggs, the golden cicada punctures the epidermis of the branches and lays the eggs in the xylem. During the mating and laying period of the golden cicada, try not to walk and make noise in the greenhouse, so as to avoid adverse effects on the golden cicada.

Due to the unearthed nymphs (cicada turtles) and adult natural enemies, such as toads, sparrows and mantis, we should do a good job of protection in the greenhouse. In addition, we should always check whether the screen is damaged and strictly prevent the golden cicada from escaping.

Beauveria bassiana, Beauveria bassiana and entomogenous algae (cicadas) and other microorganisms can cause parasitic harm to golden cicadas, so protection should be strengthened during culture. The main natural enemies of golden cicadas are ants and red flower bugs, which must be strictly guarded against during the emergence of mature nymphs, eggs under trees and the occurrence of cicadas. Strong ammonia can be used for soil treatment.

Preliminary preparation for breeding golden cicada

1. Feed supply

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

2. Environmental conditions

The "breeding" depth of grasshopper cicada should be 30cm to 50cm. It should be sunny and frostproof, the soil should be soft, fertile and pollution-free; it should not be too dry, nor should it have too high water content or stagnant water, so as to ensure the normal growth and development, tender, developed and succulent root system of host plants. In winter, wheat straw, rice straw and corn straw should be covered in the breeding area to maintain the ground temperature. [1]

3. Preparation for epidemic prevention

Unearthed nymphs (cicadas) and adult natural enemies after Eclosion, such as toads, snakes, rodents, hedgehogs, wild cats, sparrows and mantis all like to eat nymphs (cicadas). Beauveria bassiana, Beauveria bassiana and entomogenous algae (cicadas) are also parasitic. In addition, the pollution of floods and pesticides and chemical fertilizers also do great harm to nymphs (cicadas) or cicadas, which should be added when breeding.

4. Attention and protection.

The most important seasons are the egg stage on the tree, the occurrence period of "cicada ants" and the unearthed period of mature nymphs. The natural enemies of egg stage and cicada ant occurrence period on trees are mainly ants and red flower bugs. The treatment measures are to use 100-fold solution of strong ammonia to wash egg branches or DDVP, strong chlorine and so on for soil treatment.

5. Breeding technology

The construction of adult and nymph production facilities can not only naturally collect cicada eggs, but also build a screen greenhouse to provide golden cicada adult spawning space. 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. Eclosion or collection of adults in which they mate and lay eggs, the number of adults can be retained as needed in the future, and there is no need to collect provenances from the wild.

Sowing time of golden cicada

The planting time is usually from May to July or from September to October. About 1 meter from the base of the trunk, dig regular narrow trenches about 10 to 30 centimeters deep, such as ring, square, triangle, parallel or radiation, for future digging and harvesting. The back cover soil of "breeding seed" is compacted, and the time, quantity, groove shape and depth of "breeding seed" are recorded. To sunny anti-freezing, soil soft, fertile, pollution-free; not too dry, not too high water content 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.

The harvest of golden cicada

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.

The above is about the technology of raising golden cicadas, which is very helpful information for friends who want to raise golden cicadas. The golden cicada has a high use value and a wide range of uses, whether as a nutritious delicacy or a very good traditional Chinese medicine.
