Culture technology and yield of golden cicada

The culture technology of golden cicada: some exuberant tree species or rhizome plants can be planted, and the depth of "breeding species" is about 30-50cm, during which snakes, hedgehogs, rats and microorganisms should be prevented, and egg branches should be washed with 100-fold solution of strong ammonia, and then a screen greenhouse should be built. The yield of golden cicada: the yield per mu is about 100-300 jin.

I. Culture techniques of golden cicadas

1. Feed supply

Choose to plant some robust tree species with developed root system, exuberant growth and more juice, such as poplar, elm, willow, paulownia, or various fruit trees in the orchard, as well as some rhizome plants, such as sweet potato, potato, yam and so on.

2. Environmental conditions

(1) the "breeding" depth of the golden cicada is about 30-50 cm, the terrain should be sunny, which is conducive to anti-freezing, and the soil should be fertile, soft, pollution-free, not too dry, and the water content should not be too high, as well as the phenomenon of stagnant water.

(2) in order to ensure the normal growth and development, tender and succulent root system of host plants, a layer of rice straw, wheat straw and corn straw can be covered in the breeding area in winter.

3. Preparation for epidemic prevention

The main results are as follows: (1) there are many natural enemies of unearthed nymphs and feathered adults, such as snakes, hedgehogs, rodents, wild cats, toads and so on. In general, sparrows and mantis love to eat nymphs, while Beauveria bassiana, entomogenous algae and other microorganisms also have parasitic hazards, as well as floods, pesticides, fertilizers and other pollution, which are also relatively harmful to golden cicadas, so in the process of breeding, we should pay attention to the corresponding protective measures.

(2) the more important seasons are the egg stage on the tree, the occurrence period of "cicada ants" and the unearthed period of old mature nymphs. The main natural enemies in the egg stage and cicada occurrence stage are ants and red flower bugs. Generally, the egg branches can be washed with 100x solution of strong ammonia, or the soil can be treated with DDVP, strong chlorine and so on.

4. Breeding technology

(1) in general, the production facilities of adults and nymphs can not only naturally collect cicada eggs, but also build a screen shed, which can provide space for adults of golden cicadas to lay eggs, and can also use fruit trees in abandoned orchards to replant fruit tree seedlings.

(2) around the seedlings of fruit trees, cement columns or bamboo bars can be used to build fences, and iron wires can be drawn in the middle, and the outer layer can be covered with a layer of nylon window screen, and for adults that are feathered or collected, they can mate and lay eggs, and adults can be retained according to the number in the future, and there is no need to collect provenances from the wild.

Second, the output of golden cicada

There are 2000 golden cicada seedlings per mu, and each branch contains 100 golden cicada eggs. Generally, the artificial hatching golden cicada eggs can reach more than 80%, so the yield per mu is about 100,300jin.
