What kind of soil should be selected for golden cicada breeding? What are the daily management points?

Golden cicada is a kind of income-increasing project which combines forest and fruit planting, green planting, and then comprehensive utilization of woodland resources. What kind of soil should be chosen when raising golden cicadas? What are the key points of daily management?

First, what kind of soil should be chosen for golden cicada breeding?

1. Red soil is not suitable for raising golden cicadas.

Red soil is easy to harden and is not suitable for the growth of golden cicadas. Because the golden cicada larvae are relatively young, if they encounter red soil that is easy to solidify, it is not easy to drill into the soil. Only in soft sand or loam can young cicadas quickly dive into the soil to find roots and start the normal growth process. Therefore, the best cicada breeding base is sandy land, followed by loam. Practice has proved that the cultivation of golden cicada on sandy land has the characteristics of high survival rate, high yield and good taste, so it is the most ideal soil.

2. Golden cicada can be cultivated in sandy soil, black soil and silt soil.

The most suitable place for raising golden cicadas is sandy land. Is it possible that other soils (such as silt or black soil) can not be used to raise cicadas? The answer is no. According to the relevant experience, even if there is no sandy soil, the golden cicada can be successfully raised with silt or black soil and high yield can be obtained. The trick is to plant willows with fast-growing roots when selecting host plants, and to throw in more egg branches when breeding. After using these two methods, we can completely make up for the shortcomings of the soil.

3. Do not choose the soil contaminated by chemical fertilizers and pesticides

In addition, because chemical fertilizers and pesticides do some harm to the golden cicada, when selecting soil, it is best to use land that has not used chemical fertilizers and pesticides. Because after the use of chemical fertilizers and pesticides, they will precipitate into the soil, and some of them will even sink to a depth of more than 100 meters. Therefore, such land can be called polluted land. If golden cicadas are raised on such land, it may harm golden cicadas or affect yield.

Second, what are the main points of daily management of golden cicada breeding?

1. Select breeding trees

Dwarf fruit trees such as apricot, peach, apple or other surface wax 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 between trees, in order to increase the branches of golden cicadas to lay eggs, and reproduce golden cicadas under trees to plant eggs. The method refers to "New Technology of Golden Cicada Culture"

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 has a strong phototaxis, in the early stage, the feathered golden cicada entered the greenhouse after the emergence of adult worms, and when caught, the feathered golden cicada would fly around and bump around, 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 a week later. The seed density is about 10000 per mu, and each female and male account for about 50%. Each female golden cicada can lay 500-1500 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.

4. Harvest and preserve the eggs

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. 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.

Early and late September is the best season for collecting golden cicada eggs in the breeding greenhouse. A fruit branch shears or a long rod with a hook at the top can be used to remove the 1-2-year-old thin dry and incomplete surface on the tree killed by eggs, and the subcutaneous xylem embedded with a large number of milky long oval eggs, that is, cicadas eggs, cut off the extra non-egg withered shoots in the upper part of the spawning nest, leave 5-10 cm egg-free branches in the lower part of the spawning nest mark, tie 50-inch 100 branches into a small bundle, put them in a plastic bag or flat code in the hatchery. After natural treatment, it can be used as a seed.
