CATDOLL : CATDOLL: Natural conditions for silkworm breeding (What are the natural conditions for silkworm breeding)

1. What kind of environment should silkworms grow in?

Silkworms are best suited to living in a smoke-free, odor-free environment, and growing in a clean box without moisture. They are suitable for growing in an environment with a temperature range of 22-29 degrees Celsius, and the most suitable growth temperature is around 27 degrees Celsius. The breeding environment should be kept cool, ventilated, breathable, and pollution-free. Prevent mosquitoes, cockroaches, flies and other pests. Keep away from toxic and odorous items, and avoid burning mosquito coils, spraying insecticides, wind oil essence, perfume, etc. indoors.

2. What are the growth environment requirements for silkworms?

Temperature: The temperature range for silkworm growth and development is 20-30℃. The suitable temperature for feeding and rearing is usually 27-28℃ for the first instar, 26-27℃ for the second instar, 25-26℃ for the third instar, 24-25℃ for the fourth instar, and 23-24℃ for the fifth instar. It should be kept at 24.5-25℃ in the early stage of cocooning and 24℃ in the late stage of cocooning. Humidity: The relative humidity is 95% in the first instar, and it decreases by 5-6% with each subsequent instar.

3. What conditions are required for raising silkworms?

1. There must be a suitable mulberry garden. According to the current sericulture model, raising silkworms requires sufficient mulberry leaves. If there are no mulberry leaves, there is no way to raise silkworms well. Therefore, before starting to raise silkworms, you must first determine the source of mulberry leaves. When planting mulberry trees at home, pay attention to the selection of plots and try to make the mulberry gardens contiguous. This is very helpful for preventing silkworm diseases.

2. There must be a silkworm house for raising silkworms. The silkworm house can be said to be indispensable in the process of raising silkworms, just like mulberry leaves. If there is no suitable silkworm house, the silkworms will have no place to live.

3. You need silkworm tools, cocoon tools, silkworm medicine, etc.

4. Order an appropriate amount of silkworm seeds.

4. Is Northeast China suitable for silkworm breeding?

The main natural condition that affects silkworm breeding is climate. The Northeast has a temperate monsoon climate. Although the summer is hot and rainy, it is short. Mulberry leaves can only be picked in the summer, and the picking period is short. The winter is cold and dry for a long time, and there is no mulberry leaf picking. The cold weather is not conducive to the mulberry babies to survive the winter. Therefore, the Northeast is not suitable for silkworm breeding.

5. What are the environmental requirements for mulberry tree growth?

Mulberry trees prefer warm and humid climates and are slightly shade-tolerant. They begin to sprout when the temperature is above 12°C, and their optimum growth temperature is 25-30°C. They are inhibited when the temperature exceeds 40°C, and stop growing when the temperature drops below 12°C.

Drought-resistant, not waterlogged, and barren-resistant. Strong adaptability to soil. The growth temperature of silkworms is 7-40℃, and the suitable temperature for feeding is 20-30℃. The general indoor temperature from May to September is suitable for silkworm breeding.

It likes light and has strong adaptability to climate and soil. It is cold-resistant and can withstand temperatures as low as -40°C. It is drought-resistant but not water-resistant. It can also grow in a warm and humid environment.

It likes deep, loose and fertile soil and can tolerate mild salinity (0.2%). It is wind-resistant, smoke-resistant and toxic. For your reference, I wish you a happy life!

6. What altitude is suitable for silkworm breeding?

Answer: Traditional silkworm breeding areas in my country are spread across the middle and lower reaches of the Yangtze River. From Sichuan to Jiangsu, Zhejiang and other provinces along the river, there is a tradition of silkworm breeding, so there is no specific requirement for the altitude of silkworm breeding. As long as the area is suitable for the planting and growth of mulberry leaves, the sericulture industry can be developed. However, silkworms are more suitable for warm and humid climate conditions. High temperature, drought and cold areas are not conducive to the growth of mulberry trees, nor are they suitable for the development of silkworms.

7. In what kind of environment can silkworms grow? In what kind of environment can mulberry trees grow?

Whether the living environment of silkworms is comfortable or not is mainly determined by the four conditions of air cleanliness, temperature, humidity and airflow. The airflow regulates the other three, thus affecting the physiology of silkworms. When there is airflow, the moisture of the silkworm body and silkworm seat is easy to dissipate, and the temperature of the silkworm body is generally slightly lower than the air temperature. When there is no airflow, it is slightly higher than the air temperature. During the adult period, silkworms eat a lot of mulberry and excrete a lot. The accumulation of residual mulberry can easily make the silkworm seat hot and humid. Especially in summer and autumn when the temperature is high, the temperature of the silkworm body is higher than the air temperature, affecting the normal physiological activities of the silkworm. In order to provide adult silkworms with enough fresh air, strengthen the physical fitness of silkworms and prevent air pollution and heat in the silkworm seat, full attention must be paid to strengthening ventilation.

The development temperature of silkworms is 7-40℃, and the suitable temperature for breeding is 20-30℃. The general indoor temperature from May to September is suitable for raising silkworms.

Mulberry: It likes light and has strong adaptability to climate and soil. It is cold-resistant and can withstand temperatures as low as -40°C. It is drought-resistant but not water-resistant. It can also grow in a warm and humid environment. It likes deep, loose and fertile soil and can withstand mild salinity (0.2%). It is wind-resistant, smoke-resistant and toxic. It has a well-developed root system, grows quickly, has strong germination ability, tolerates pruning, and has a long lifespan, which can generally reach hundreds of years. Some can even reach a thousand years.
