Nail art is a kind of
work to decorate nails (toe), also known as art design. Nail is the process of
disinfecting, cleaning, nursing, maintaining, and beautifying the finger (toe)
armour according to the guests' hand shape, nail shape, skin texture, and the
color and requirements of the clothing. To complete this process, it is
necessary to rely on the nail table, Manicure Table is also divided into two
categories, one is the Wood Top Manicure Table, the other is the glass top
manicure table. It is divided into a single nail table and a double nail table.
It is divided into a table with no drawers and cabinets, can it be folded, etc.

It is expected that the yield of per unit area will be high for artificial breeding, while the yield per unit area will be closely related to individual weight gain and breeding density. To increase the yield per unit area, the breeding density must be increased within certain limits. However, if the culture density is too high, it will cause individuals to grow and reproduce at a reduced rate. Of course, the size of the breeding density is not absolutely the same, with the size of the individual and the quality of the feed, the quality of the management, the temperature of the appropriate changes. Therefore, choosing a reasonable breeding density depends on the specific circumstances, such as adequate feed quality, good management, and high density; otherwise it is small. In addition, the density during the pupal stage can be large and the size of the pupae can be small. For the purpose of protein production, the density can be large; for the purpose of reproduction, the density can be appropriately reduced.
2. Temperature control and regulation.
The main effect of temperature on earthworms is to affect their metabolism, thereby affecting their growth and egg production. As mentioned earlier, the optimum temperature for spawning eggs is 21°C-25°C. The temperature is too low and the number of eggs laid is significantly reduced. In the optimum temperature range, the temperature increases, the number of eggs laid increases, but when the temperature exceeds 25°C, the number of eggs laid gradually decreases. Under suitable conditions of temperature control, earthworms can grow and reproduce throughout the year.
3. Control and regulation of humidity.
蚯蚓 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜 喜. For example, ring soil lice, heterolipa and other requirements of soil moisture content of about 30%; Aiko Ai Sheng, "Daping II" and other fleas, the main cultured in organic feed, the water requirements and the above-mentioned glutinous species, the general requirements Bait moisture content 60% -70%. If the feed contains too much water. Impairs oxygen in the pores between feeds, making them unable to live. As a result of excess water, the egg production rate is reduced and the eggs produced are also rotted or dissolved. In a humid environment, diseases can also be easily caused, resulting in reduced production.
With too little water, the bait is too dry and it is unfavorable for feeding. At the same time, it causes the quail to excessively secrete body fluids, causing water loss in the body and metabolic regurgitation and stopping ovulation.
Humidity hatching humidity, the general requirements of 56% -66% is appropriate, excessive humidity or poor ventilation, egg metamorphosis can be black. In production, summer can increase water consumption in order to reduce the temperature. Generally, water is applied once every morning and evening. In winter, water can be reduced, and the breeding of aerobic microorganisms can be accelerated, and the temperature of the material can be raised. Generally, watering is performed once every 3-5 days.
4. Control and adjustment of PH value.
The growth and reproduction of earthworms are closely related to the pH of the diet, and it is generally 6.8-7.6. If too high or too low, adverse reactions often occur, such as carcass becoming dry, into a beaded shape, dehydration shrink, body color becomes dark purple, feeling dull, and even affect the production of escape.
Substances with higher protein content will produce a certain amount of ammonia during fermentation, which will increase the pH of the feed. Substances with a low protein content will require a reasonable mix of nitrogen and carbon for fermentation. It must be determined before feeding the feed. If the pH is high or low, it should be adjusted. When the PH value is high, the pre-prepared carbon bait may be added to adjust; when the pH is low, lime water supernatant (pH=9) may be added to adjust.
