CATDOLL : CATDOLL: Month for raising silkworms (in which month do you raise silkworms)

1. Which season is suitable for raising silkworms?

Spring or Summer

Answer 1. Silkworm rearing time: Generally, silkworm rearing takes place in spring and summer (starting around April). Silkworms mainly feed on mulberry leaves, so silkworm rearing needs to be basically consistent with the growth cycle of mulberry trees, so that there are enough mulberry leaves for silkworms to eat. 2. Silkworm rearing frequency: In Jiangsu and Zhejiang silkworm regions, silkworm rearing can be carried out theoretically from April to November each year, but generally only 3-5 times.

2. Which month is it best to raise silkworms?

March-June.

The most suitable time for raising silkworms is generally March in spring and May and June in summer.

March is the time when mulberry leaves sprout and grow leaves. Spring silkworms at this time have tender mulberry leaves to eat. With sufficient mulberry leaves to feed on, the silkworms grow bigger and fatter.

3. Which month is it best to raise silkworms?

1. Generally speaking, the season for raising silkworms is spring and summer every year (starting around April each year). Since the main food source for silkworms is mulberry leaves, the season for raising silkworms and the growth cycle of mulberry trees need to be roughly the same to ensure that there are enough mulberry leaves to feed the silkworms.

2. The season of sericulture is related to the region. In the sericulture areas of Jiangsu and Zhejiang, theoretically, sericulture can be carried out during the eight months from April when mulberry trees sprout and open leaves to November when mulberry leaves turn yellow and fall off, but generally only 3-5 times a year. The sericulture areas in the Pearl River Basin raise sericulture more frequently than those in Jiangsu and Zhejiang, while some sericulture areas around the Yellow River or in the north raise sericulture less frequently than those in Jiangsu and Zhejiang.

4. What is the best season for raising silkworms?

Silkworm breeding time: Usually, silkworm breeding takes place in spring and summer (starting around April each year). Because silkworms mainly feed on mulberry leaves, the breeding of silkworms needs to be closely related to the growth cycle of mulberry trees.

5. Which month is it best to raise silkworms?

Raising silkworms on mulberry leaves is a good time to do so in June. In June, mulberry leaves are lush, nutritious and easy to feed, so there is enough food for the silkworms. The temperature is also suitable, the silkworms grow fast and the production cycle is short, so it is a good time to raise silkworms.

6. What is the specific time for raising silkworms?

Silkworms are generally raised in the summer, which is roughly the same as the growth cycle of mulberry trees, to ensure an adequate supply of mulberry leaves.

Silkworm (scientific name: Bombyx mori) is an insect of the order Lepidoptera. It is the main source of silk and plays an important role in human economic life and cultural history. It is native to China and is commonly known as silkworm or nymph in southern China and Taiwan.

The silkworm is called "silkworm" in English because it uses silk to make cocoons. A cocoon is made from a strand of silk that is 300-900 meters long. Today, my country's silk production and exports account for more than 70% of the world's total, and it has become a major silk country that can dominate the world's silk price trend.

7. When can I raise silkworms?

In addition to winter, spring, summer and autumn are all possible. Generally speaking, as long as there are mulberry leaves, silkworms can be raised. In Jiangsu and Zhejiang regions of my country, silkworms can be raised in spring, summer and autumn except winter. In the silkworm areas of Jiangsu and Zhejiang, silkworms can be raised within 8 months from April when mulberry trees sprout and open leaves to November when mulberry leaves turn yellow and fall off.

During the growth and development of silkworms, the temperature of the surrounding environment is relatively high. From the hatching of silkworm seeds to the final cocooning, the temperature in the silkworm room needs to be controlled at 24-28℃. Of course, the temperature control needs to be slightly adjusted according to the different silkworm stages. During the 1-5 years of silkworms, if the temperature in the silkworm room is lower than 20℃, the silkworms will obviously slow down their feeding of mulberry leaves, and large and small silkworms are likely to appear; if the temperature in the silkworm room is higher than 30℃, the silkworms will appear irritable and restless. In addition, when the relative humidity in the silkworm room is greater than 90% and the silkworm feces are thick, it is easy for bacteria to breed in the silkworm seat, thereby inducing a variety of silkworm diseases and causing great losses to farmers. Therefore, during the entire silkworm period, the temperature and humidity in the silkworm room must be strictly controlled to create a relatively good growth environment for the silkworms, avoid the phenomenon of hot and cold, and the indoor temperature can only fluctuate within a small range.

8. Which month is it best to raise silkworms?

The silkworm breeding period is generally from April to November, that is, from the time when mulberry leaves sprout and open to the time when mulberry leaves turn yellow and fall off. It takes about 40-50 days for silkworms to transform from eggs into moths, which is related to factors such as temperature, humidity, and feeding in the growing environment.

9. When does one start raising spring silkworms?

1. Time for raising silkworms

Generally speaking, silkworm breeding starts around April each year, specifically in spring and summer. Since the main food source for silkworms is mulberry leaves, the breeding of silkworms needs to be basically consistent with the growth cycle of mulberry trees, so as to ensure that there are enough fresh mulberry leaves for the silkworms to eat.

2. Number of times of raising silkworms

The number of times silkworms are raised each year is related to the region. In the Jiangsu and Zhejiang silkworm areas, silkworms can be raised theoretically in the eight months from April (when mulberry trees sprout and open leaves) to November (when mulberry leaves turn yellow and fall off), but generally only 3-5 times a year. The silkworm areas in the Pearl River Basin raise silkworms more often than those in Jiangsu and Zhejiang, while the silkworm areas around the Yellow River and the northern regions raise silkworms less often than those in Jiangsu and Zhejiang.

2. What factors should be paid attention to in silkworm breeding?

1. Temperature

The suitable temperature for first-instar silkworms is 27-28℃, the suitable temperature for second-instar silkworms is 26-27℃, the suitable temperature for third-instar silkworms is 25-26℃, the suitable temperature for fourth-instar silkworms is 24-25℃, and the suitable temperature for fifth-instar silkworms is 23-24℃.

2. Humidity

The suitable humidity for first-instar silkworms is 80-85%, the suitable humidity for second-instar silkworms is 85-90%, the suitable humidity for third-instar silkworms is 75-80%, the suitable humidity for fourth-instar silkworms is 70-75%, and the suitable humidity for fifth-instar silkworms is 65-70%.

3. Mulberry leaf selection

(1) One-year-old silkworms: Use the third leaf from the top bud on the mulberry tree, which should be yellow with green in color.

(2) Second-instar silkworms: Use the fourth leaf from the top bud on the mulberry tree, which should be green with yellow in color.

(3) Third-instar silkworms: Use the 5th to 6th leaves from the top bud on the mulberry tree. The leaves should be light green and shiny.

(4) For fourth- and fifth-instar silkworms: Use the 7th to 15th leaves from the top bud, and the leaves must be fresh.

(5) There should be no water on the mulberry leaves.

4. Other matters needing attention

(1) When the temperature is high, you need to open doors and windows for ventilation.

(2) When raising silkworms, avoid direct sunlight.

(3) Mosquito-repellent coils should not be used in silkworm breeding areas because they are poisonous to silkworms and bees.

October. Which month do we start raising silkworms?

Around April.

Generally speaking, silkworm breeding starts around April each year, specifically in spring and summer. Since the main food source for silkworms is mulberry leaves, the breeding of silkworms needs to be basically consistent with the growth cycle of mulberry trees, so as to ensure that there are enough fresh mulberry leaves for the silkworms to eat.

In the sericulture areas of Jiangsu and Zhejiang, silkworms can theoretically be raised during the eight months from April to November each year, but generally only 3-5 times.
