What is the culture technology of golden cicada? Which areas are suitable for raising?

As people pay more and more attention to the concept of healthy diet, golden cicada will become one of the important green foods for human beings. Because of low investment, easy to master technology, labor saving, high benefit and low risk, artificial cicada breeding is rapidly becoming a new project to get rich in rural areas. So what is the culture technology of golden cicada? Which areas are suitable for raising?

In which areas are golden cicadas suitable for breeding?

1. Areas suitable for breeding golden cicadas

Basically, the main areas suitable for farming in China are Shanghai, Jiangsu, Zhejiang, Hebei, Shaanxi, Shandong, Henan, Anhui, Hunan, Fujian, Taiwan, Guangdong, Sichuan, Guizhou and Yunnan. At present, the provinces where golden cicadas are farmed in large quantities are mainly Shandong, Jiangsu, Hebei, Henan, Hubei and Sichuan.

2. Feeding conditions of golden cicada

The golden cicada is mainly cultivated in forests, as long as there are forests or land to plant trees and perennials, and there is no need to build breeding farms, nor do they need to purchase breeding facilities and equipment and spend money on building breeding facilities. The main capital expenditure is the purchase of provenances, suitable for starting a business.

In addition, there is a simple way to judge whether golden cicadas can be raised in a certain place:

As long as wild cicadas can be heard in the local woodland in summer, it shows that the place can be farmed.

If cicadas have never been heard in summer, it means that a certain condition such as local climate, soil or tree species may not be suitable for the growth of golden cicadas. At this time, a small number of breeding experiments are needed to determine whether they can be cultured or not.

Second, what is the culture technology of golden cicada?

1. Egg collection and breeding of golden cicada

One is to collect eggs for breeding, and the other is to buy eggs.

Egg collection by oneself can concentrate the egg-bearing branches collected directly from the wild or in the provenance site indoors to promote hatching.

Hatching method: in the plastic box which is 70 cm long, 40 cm wide and 20 cm high, spread fine dry sand 5 cm to 10 cm thick at the bottom, 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-bearing branches and make the excess water droplets adsorb 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.

However, it should be noted that the eggs of wild golden cicadas have some disadvantages such as inconsistent emergence, mixed varieties and low yield. in addition, it is best not to use golden cicadas in fruit trees to plant eggs, because the eggs in fruit trees are seriously harmed by pesticides and the survival rate is low. large-scale breeding should be purchased from formal professional farms.

2. Breeding of golden cicada

The breeding time is generally from May to September. Dig regular narrow trenches about 30cm to 50cm deep in the ground about 1 meter away from the base of the trunk, such as ring, square, triangle, parallel or radiation, in order to dig and harvest in the future. The soil behind the "breeding seed" is compacted, and the time, quantity, groove shape and depth of the "breeding seed" are recorded.

In the selection of tree species, healthy tree species with developed root system, luxuriant growth and more juice should be selected for breeding, such as poplar, elm, willow, paulownia or all kinds of fruit trees in the orchard. In addition, dwarf shrubs such as honeysuckle and green wax are also crops that golden cicadas like to eat, and cicadas cannot be raised under trees such as pine and bitter ripples. Because the roots of pine trees have a special pine flavor, golden cicadas do not like to eat, and the bitter sap golden cicada larvae do not like to eat.

Warm reminder: from the egg stage to the growth and development of mature nymphs, golden cicadas need to grow underground for three winters and summers (actually 2 years). The short growth cycle of artificially cultivated golden cicadas shortens its growth time, and it can be unearthed naturally in 2-3 years, and the return period is short. Each mu can produce 20,000 to 30,000 golden cicadas a year, with an income of more than 8000 yuan.
