First, the form of farming.

Eupolyphaga has strong vitality. Eupolyphaga can survive as long as it is not exposed to the outdoors, wind and rain, and direct sunlight. Loose soil and dark and humid environment can make Eupolyphaga grow well. The following are several farming methods:

1, potted plants

You can choose a plastic basin with smooth inner wall, the height is more than 1.5 cm, and the diameter is 45-60 cm, so you can directly raise it with the built-in feeding soil. Potted plants are suitable for small-scale farming, with small investment, simple operation and flexible movement.

2, cylinder maintenance

Earth basin with smooth inner wall shall be selected, and the height of the cylinder shall not exceed 1 m, and it shall be partially or partially buried underground. Feeding soil can be placed 40-50 cm thick, with stable underground temperature and humidity balance, good growth of soil elements, long service life and good output quality.

3. Pond culture

Flat pond culture is the predecessor of three-dimensional greenhouse culture pond. Build a square or rectangular pool with a height of 40-50 cm with bricks on the indoor concrete floor, leaving a walkway of 1m, laying bricks on both sides of the pool or indoors, and laying boards for walking operation. Group four. While painting the upper edge of the inner wall, paste 6-8 cm glass strips with cement slurry (thick film can be used instead of glass strips) to prevent Eupolyphaga from escaping. The Eupolyphaga sinensis cultivated by this method has the advantages of good growth, simple management and low investment.

4, three-dimensional feeding

Today, we advocate a more advanced three-dimensional culture mode in greenhouse. The requirements for building a corpse pool are that the house should not leak rain, the surrounding walls should be intact, and the top of the house should be flat. Doors and windows are left around the house, and the partition wall is made of vertical bricks, with a gap of 5- 10 cm from the original wall. At regular intervals, the top brick is used to build the partition wall against the original old wall. In case the partition wall collapses, its function is to keep warm and moisturize, which is of great significance to the cultivation of Eupolyphaga. After the partition wall is built, the size of the feeding soil slab is designed according to the remaining area of the room of 0.95- 1 m, and the thickness of the feeding soil slab is 3-3.5 cm, and it will be poured with reinforced concrete after the size is determined. After the soil slab is poured and maintained, the three-dimensional soil pool can be built. Each floor has 3 vertical bricks (about 40 cm high). After the first floor is completed, paint the interior wall, and then lay a layer of clay board. You can build 6-7 floors and cap them. Leave an operation window of 19-20cm on the walkway side of Eupolyphaga House, and stick a piece of hard plastic paper of about 4cm into Eupolyphaga Pool along the operation window to prevent Eupolyphaga from escaping. After the adobe house is built, paint the surrounding interior walls and fill in the hole to prevent rats and ants from entering. 5. In the process of artificially raising Eupolyphaga, heating culture is particularly important. Heating the culture pond can shorten the growth cycle by one third. Although heating has increased part of the cost, the benefits generated by comparison are negligible, and heating methods can also be adopted according to local conditions.

Second, tools, feed, feeding soil

1, culture tools

Long footbath-used to soak feed and keep feeding soil while screening insects and eggs. Round foot basin-used to hold feeding soil, insects, egg pieces and feed when feeding. 2 mesh (1cm) sieve-used to screen insects. 6 mesh (4 mm) sieve-used to screen larvae and egg pieces. Window screen-used to screen mites. Long board-used to enclose pit soil, 25-80 cm long and 8- 10 cm wide. Two-phase traveling light-used for mobile lighting in mine room. Thermometer-placed in the pit for a long time to measure the temperature. Scraper-used to dig out the soil and insects in the pit. Crusher-large farms are used to crush feed and soil. Dustpan-used to move soil, dust empty shells, etc.

Step 2 feed

Eupolyphaga has a wide range of foods. Wheat bran, rice bran, vegetable leaves, roots, stems, flowers, beans and leaves of melons are all good feeds for Eupolyphaga. We usually use wheat bran, vegetable leaves, melons and other easily available and cheap feeds. Pesticide pollution should be avoided in green vegetable feed. Grasp the season in the process of feeding green feed, and adopt specific green feed according to the time period.

Step 3 feed the soil

Eupolyphaga can adapt to various soil minerals. After artificial feeding, the feeding soil is specially prepared for its management. Garden soil, mountain mud and leaf humus soil are generally used as feeding soil. Firstly, impurities such as large clods and leaves are screened out with a 6-mesh sieve. It can also be crushed by a pulverizer and then sieved. The fine soil is mixed with 30%-50% plant ash. Raising soil requires a certain degree of humidity, and generally the soil is sticky. When mixing soil, water should not be sprayed directly on the soil, but should be sprayed on plant ash or sawdust first, and then mixed into the soil. Pig manure, cow dung and cinder can also be mixed in. Note that pig manure and cow dung can only be used after fermentation. Pure soil can also be used to raise Eupolyphaga. Its disadvantage is that the humidity is difficult to control and the soil element does not go deep into the soil. In short, the preparation of feeding soil should be loose, breathable and not fermented to meet the growth needs of Eupolyphaga. Three, Eupolyphaga seed retention and incubation management

Breeding industry involves seed selection and seed retention. Eupolyphaga reproduction mainly adopts the following methods:

1. Incubation propagation method: This propagation method is widely used, with small weight of incubation block, large propagation coefficient and convenient transportation.

2. Larvae introduction and propagation method: this introduction method is practical, the larvae are small and easy to carry.

3. Adult introduction and propagation method: This introduction method is more economical. After introduction, you can lay eggs and raise them yourself. When adults get burned, they can sell part of the cost and it is difficult to transport.

We usually talk about introducing eggs and keeping seeds. First of all, look at whether the egg worms are strong, and the females are uneven and die too much. Generally, the second and third batches of eggs are screened, which are neat and firm and easy to hatch and manage. In the whole feeding process of Eupolyphaga Seu Steleophaga, the hatching management of eggs is the key link. It is directly related to the success or failure of feeding and economic benefits. There are many incubation methods, such as (1) indoor temperature control incubation (2) constant temperature incubator (3) kerosene lamp heating incubation. In our opinion, the latter two methods are not as direct as indoor temperature control incubation. 4-5 kg of breeding eggs can be put into a plastic basin with smooth inner wall and diameter of 50 cm, and two-thirds of breeding soil for breeding eggs can be mixed. The humidity of the feeding soil is kept at about 35%-40% (it will be broken by hand). After 3-5 days, the soil will gradually dry out. At this time, you can't spray water on it to humidify it. You should screen out the dry soil and mix in the new preheated soil. During the incubation period, the temperature should always be kept at 25-30℃, with 28℃ being the best. Turn eggs 1-2 times a day by hand to increase the freshness of soil air. Turn it gently to avoid hurting the egg pieces. After 30 days of incubation, some larvae begin to hatch, and then we will see thousands of larvae. Screening once every two days to separate larvae in proportion. When screening insects, be gentle with your hands and feet to avoid hurting larvae. After a large number of insects were released, the empty shells of some insects were mixed with them. When there is noise in the process of insect screening, the empty shell can be dusted off with a dustpan. 4. Temperature and humidity control

Eupolyphaga is oval, with large surface area and fast water discharge in the body. When the temperature is lower than 20℃, the molting grows slowly, and when it is higher than 38℃, it stops growing, making it fidgety and crawling on the surface of feeding soil. Therefore, the temperature and humidity control of artificially raised Eupolyphaga sinensis should adapt to its needs and achieve the best reproductive effect. Manual humidity control can also prevent too high and too low. Among them, the requirements of soil elements of different ages for humidity are also different. The quality of hatching eggs is 28℃-30℃, larvae are 28℃-32℃, and adults are 25℃-28℃. The manual control of humidity is also different at each stage. When hatching eggs, 35%-40%, larvae 35%, midges 40% and adults 45%. Wild Eupolyphaga mostly grows in dark and humid environment and is afraid of direct sunlight. Through artificial propagation, it is not difficult to create this optimal growth condition for it. Doors and windows are blocked with sacks or dark snakeskin bags, and the moisture in the pit room slowly loses. During heating culture, the moisture loss of the feeding soil is fast, so a special sprayer without pesticide pollution can be used to spray water on the surface of the feeding soil and the pit wall, which requires uniform spraying and few times.

5. Feeding management

Eupolyphaga's living habit is to lie down during the day and go out at night. Active every day 18:00-24:00. At the peak of eating, each Eupolyphaga does not eat every day, and once it is eaten, it lurks in the soil for 2-3 days. The artificial breeding of Eupolyphaga requires feeding food at 5-6 pm every day. The feeding amount should be flexibly controlled according to the food intake of insects in each growth stage, and more observations and summaries should be made. Too little feeding is not conducive to the growth of insects, and too much feeding will waste feed and lead to a large number of mites, which is also not conducive to the growth of insects. There are three feeding methods: (1). Squeeze the feed into small balls and feed them at different points (suitable for larvae). (2) Sprinkle the feed on the surface of the feeding soil (suitable for midges). (3) Make a dining table with 15 * 15 cm plastic film, and put the feed on the dining table (suitable for adults).

6. Carrying capacity

Eupolyphaga grows by molting, and its body doubles every time it molts. We calculate every molting according to its age. The male Eupolyphaga molts for 9 times and the female Eupolyphaga molts 1 1 time. The artificial feeding process of Eupolyphaga Seu Steleophaga involves the utilization of area and the convenience of management, and the stocking density also varies according to the growth needs of insects of all ages, as shown in the following table:

8-65438+ million larvae.

50,000 1-2 years old

25 thousand, 3-5 years old.

6.5438+0.25 million 5-8 years old.

9- 13 years old 4000-5000.

The burial depth of soil elements in each stage is different. In order to facilitate management, we also listed the depth of soil feeding:

Larvae 5-8 cm

Zhongchong 8-12cm

Adult 12- 15cm
