1, feed supply
Select the healthy tree species with developed root system, lush growth and more juice, such as poplar, elm, willow, tung tree or various fruit trees in the orchard. In addition, intercropping some root plants, such as potatoes, sweet potatoes, yams and so on.
2, environmental conditions
Grasshopper "colonization" depth of 30 to 50 cm is appropriate, to the sun to prevent freezing, the soil is soft, fertile, non-polluting; can not be too dry, can not be too high water content or the existence of waterlogging phenomenon, to ensure that the root of the host plant normal growth and development, young and developed juicy. In winter, the colonized area should be covered with wheat straw, rice straw, corn stalks, etc. to maintain the ground temperature.
3, epidemic preparedness
The emergence of wakame (robin's tongue) as well as feathered adult natural enemies are more, such as toads, snakes, rodents, hedgehogs, wildcats, sparrows and praying mantis, etc. are happy to eat wakame (robin's tongue), the white fungus, the green stiff fungus and the insect-born algae fungus (cicadas) and other microorganisms are also parasitized and harmful. In addition, flooding and pollution such as pesticides and fertilizers are also harmful to the wakame (robin's tortoise) or cicadas, which should be paid attention to and protected when breeding.
The most important seasons are the egg stage on the tree, the "cicada ant" period, and the emergence of the old mature cicada. The natural enemies in the egg stage on the tree and the cicada ant occurrence stage are mainly ants and small red flower bugs, and the treatment measures are to utilize strong ammonia essence 100 times solution to dip and wash the egg-bearing branches or DDVP, strong chlorine essence and so on to treat the soil.
4, breeding technology
Constructing adult and adult production facilities, in addition to the natural harvesting of cicada eggs, you can set up screen mesh greenhouses, to provide space for adult gold cicada spawning. You can use the fruit trees in the abandoned orchard, replant fruit tree live seedlings, around the use of cement pillars or bamboo rods erected into a fence, and then pull the middle of the wire and so on, outside the cover nylon window screen mesh can be. Feathered or collected adults in which to mate and lay eggs, and later you can leave the number of adults as needed, without having to collect seed sources from the wild.
Two, breeding process
Grasshopper successful rearing, should master the seed source acquisition, host plant selection, rearing place selection, protective measures configuration and other key points:
1, get the seed source
Primary seed source acquisition can be collected naturally in the field, eggs, worms, adults can be used as a seed source collection. 7 ~ September can be collected in each insect state; 8 ~ September is the best season to collect the worms. September is the best time to collect cicada eggs from twigs, which can be collected throughout the year. The collection of eggs can choose the ideal place where the trees are dense and the cicadas are numerous, and use fruit pruning shears or long poles with hooks at the top to take down the 1~2-year-old thin dry and withered strips of the trees that are killed by the grasshoppers' egg laying, where one side of the flattened and dried-up and incomplete surfaces are found, and a large number of milky-white, long oval eggs are embedded in the subcortical xylem, i.e., cicada eggs, and cut off the excess withered tips of no eggs on the upper part of the spawning nests, and leave out the lower part of the spawning nest scars of no eggs of 10~15 centimeters. Cut off the excess eggless dead tips in the upper part of the nest, leave 10-15 cm of eggless branches in the lower part of the nest mark, and put about 50 of them into a small bundle in a plastic bag. Capture of the caterpillars, the natural maturity of the old mature caterpillars as the object, the collection of the caterpillars can be in the evening at 7 ~ 12 o'clock in the main trunk base of the tree with a flashlight to capture; after the collection of the yarn cage into the feathering spawning. The spawning screen cage is planted with shrubby hosts, with various kinds of live fruit trees as the main ones. There are many ways to capture adult cicadas in trees, such as using fire traps at night. In order to ensure that adult cicadas are not damaged, you can use wheat gluten sticky capture, the method is to and good dough rinsed with water many times to remove starch, leaving pure gluten, stored in a wide lotus leaves, poplar leaves, glued to the top of the bamboo poles, in the early morning or during the day sticky capture of adult cicadas.
The collection of egg-laying branches should be used as the main way to obtain seed sourcesColonizing objects are the first hatchlings as well as eggs that are close to hatching. Egg-laying branches collected directly from the field or at the seed site should be gathered indoors to promote hatching. Incubation method: in a plastic box with a length of 70 cm, a width of 40 cm and a height of 20 cm, spread 5-10 cm thick fine dry sand at the bottom, put the egg branches in bundles vertically or horizontally on it, and constantly spray water with a small sprayer to keep the air around the ovipositor branches at a high level of humidity, so that the excess water droplets will be adsorbed in the fine sand at the bottom. In the middle of the egg hatching situation should be constantly spot-checked, found that the activities of the caterpillar, you can put the branch together with fine sand colonization in the breeding place.
In the feeding place of the host plant under the tree ground away from the base of the trunk about 1 meter, digging about 30 to 50 centimeters deep regular narrow grooves, such as ring, square, triangular, parallel or radial and other shapes, the purpose is to later digging and harvesting. "Colonization" after covering the soil compaction, good time, number, "colonization" ditch shape and depth and other records.
Grasshopper from the egg stage to the growth and development of the maturity of the wakame (turtle), need to grow underground for three winters and summers (actually 2 years): the first year of growth from June, the growth of the year weight of only 1 gram or so, the whole body and the eyes are milky white; the second year of the weight of the development of 3 grams or so, the whole body deepening of pigmentation, eyes pink; the third year of the development of the wakame (turtle) maturity, the weight of 4.5 ~ 5 grams, each of the wakame (turtle), the weight of 4.5 ~ 5 grams, each of the wakame (turtle). 4.5-5 grams per kilogram, an average of 210, at this time the body color is brown, eyes are black and gray. According to the size of the body weight, body color shades and eye color changes, you can accurately determine the growth and development of worms in the time age.
2, harvesting and processing
Annually, from the beginning of mid to late June (around the summer solstice) to the beginning of August (around the beginning of autumn), is the best season for field harvesting, which is most concentrated in early July or after the rainy weather. Wakame (robin's tortoise) in the wet and soft underground with a serrated pair of forelegs digging out of the hole, crawling out of the ground that is on the ground for a short period of time, and then climbed the trunk of a tree or scaffolding to prepare for moulting, the next day at 4 to 6 in the morning feathered into adult cicadas, you can use a flashlight to light the ground under the tree and the trunk of the tree at night to forage for catching, or early in the morning in the tree to catch the feathered young adult cicadas.
The harvesting of artificially reared wakame (robin's tongue) should be based on the market price during the harvesting of the ripe season in time to dig up from the ground or let it free to come out of the ground to catch. During the production season, the harvested fresh wakame should be washed with water to remove the mud and sand, one box of 100 grams each, and injected with water to submerge the wakame (robin's tortoise) in the box, and kept in the refrigerator for freezing. After re-cleaning, it can be processed and utilized. Worms (turtle) storage methods, there are long-term storage such as freezing or pickling, short-term storage such as water flooding, dilute salt water washing or natural storage after the soil.
Three, precautions
Golden Cicada breeding season: hatching golden cicada egg branches around the beginning of the solar calendar in early March to the beginning of June, hatched egg branches under the seed around the end of the solar calendar in late April to the end of June. Too early or too late will not work. (The best kind of season is the first of May to the first of June of the solar calendar)
Reasons:
(1) According to years of breeding practice and repeated experiments, the golden cicada egg period is generally 280 days to 300 days or so, into the July of the golden cicada cicada cicada eggs have begun to a large number of decline, the vitality of the lower, before hatching there is death (poplar branches are even more left), the incubation process is more likely to appear! Death. The survival rate is less than 10% of normal. (2) The golden cicada egg branches produced in the current year can't hatch small golden cicadas, because it has a dormant period. So it is the egg branches of the previous year that can be hatched. Don't be confused by the unscientific promise that some field house golden cicadas can be hatched and bred at any time.
(3) Some field home said as long as the hatching can not see the small gold cicada also have seed, pure nonsense. The consequences of such a species can only say that the survival rate is extremely low 1% or less, and the cycle to five years long. There are also said not to hatch can also be planted, so the survival rate can only say 0% or so. So if you want to breed golden cicadas, you have to grasp the time of hatching and planting. Don't listen to some irresponsible farms in August and September, but also let the seed, did not hatch to see the small golden cicada also let the seed. Be sure to plant a good hatching egg branch, must be able to see the little gold cicada wriggling.
