CATDOLL : CATDOLL: Is it better to raise silkworms in summer or spring?

1. When is the season for raising silkworms?

Silkworms are usually raised in spring and summer. The most important thing to note about silkworm raising is that the growth cycle should be the same as that of mulberry trees to ensure that the silkworms have enough mulberry leaves to eat. Silkworms are metamorphosed insects, and the most common ones are mulberry silkworms, also known as domestic silkworms.

2. 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.

3. What is the general season for raising silkworms?

Silkworms are usually raised in spring and summer. The growth cycle of silkworms should be roughly the same as that of mulberry trees to ensure an adequate supply of mulberry leaves. Silkworms are metamorphosed insects, and the most common one is the mulberry silkworm, also known as the domestic silkworm, which is one of the economic insects that feeds on mulberry leaves and spins silk cocoons.

1. Spring silkworm rearing Spring silkworm rearing is characterized by mild weather and good leaf quality. The cold weather in winter kills some pathogens, the environment is clean, and silkworm rearing is easy to obtain high-quality and high-yield. However, the temperature is often low during the young silkworm period, which does not meet the requirements of young silkworm rearing and requires heating. The probability of high temperature and sultry weather in early June is high. Therefore, spring silkworms must be raised as much as possible to achieve high-quality and high-yield; spring silkworm rearing should not be too late to avoid bad weather in the later stage; at the same time, dark fire heating should be implemented during the young silkworm period. The amount of spring silkworm rearing can be estimated by using 650~700g (buds and leaves) of mulberry per box of silkworm seeds to estimate the number of silkworm seeds that can be reared.

2. Summer silkworm rearing The characteristic of summer silkworm rearing is that the rearing period is often the plum rain season in the Jiangsu and Zhejiang silkworm areas, which easily forms a hot and humid silkworm rearing environment. Mulberry trees are mainly used for the sparse buds and leaves that grow again after summer felling, and some of the mulberry leaves that are cut in spring or the remaining leaves during the spring silkworm period are also used. The use of summer leaves combined with sparse buds and leaves is conducive to maintaining a good tree shape. Due to the high temperature and humidity, the rearing is difficult and the quality of the cocoons is poor. Therefore, summer silkworm rearing should be properly controlled. Generally, the leaves should not exceed 4 or 5 leaves at the base of the new shoots grown after summer felling. If you raise two-stage autumn silkworms or only one-stage autumn silkworms, the rearing time should be appropriately postponed.

3. Raising silkworms in early autumn

(1) The characteristics of early autumn silkworm rearing are that the natural environment is in the season with the highest temperature in the year, prone to drought and changeable. During this period, other crops are frequently treated with insect pests, which can easily cause pesticide poisoning. It is the period of the year with the worst safety for silkworm farming and the worst cocoon quality.

(2) The mulberry leaves used for early autumn silkworms are mainly the lower leaves of mulberry branches. The appropriate use of some leaves can promote the continuous growth of branches and help improve the leaf quality of mid-autumn silkworms. However, if the leaves are excessively picked, it will inhibit the normal growth of the mulberry tree, which will inevitably affect the feeding of mid-autumn silkworms and the production of spring leaves in the following year.

4. Mid-Autumn Festival Silkworm Raising The characteristic of Mid-Autumn Festival silkworm raising is that although the natural temperature begins to drop, it still exceeds the suitable temperature range for silkworm raising. Mulberry tree growth reaches its peak. If there are consecutive high temperature and drought years, the mulberry leaves will age; if early autumn silkworms are not raised, the lower leaves will turn yellow; Mid-Autumn Festival is also a season when mulberry tree diseases and insect pests are prevalent. In some years, insects need to take away leaves, so it is a period of poor leaf quality.

5. Late autumn silkworm rearing is characterized by a significant drop in temperature, especially in the late nights when the temperature is often too low; the quality of mulberry leaves is improved due to the use of the Mid-Autumn Festival, and the amount of rearing should be determined according to the situation of the remaining leaves after the Mid-Autumn Festival. Late autumn is the last period of the year. Due to the accumulation of pathogens and the large temperature changes caused by continuous silkworm rearing, silkworm diseases are often prone to occur. At least 3 or 4 mulberry leaves should be left on the branches after the leaves are harvested in late autumn to prevent the winter buds from sprouting in autumn and affecting the yield of spring leaves in the next year.

4. What is the best season for raising silkworms?

1. Silkworms are usually raised in spring and summer, which is roughly the same as the growth cycle of mulberry trees, to ensure sufficient supply of mulberry leaves. Prepare food: Mulberry leaves must be washed with clean water and dried before feeding. Do not feed silkworms with yellow and rotten leaves, otherwise the silkworms will be poisoned or have diarrhea. In order to prevent the excess leaves from wilting quickly, put them in a plastic bag, tie the bag tightly, and place it in a cool place.

2. Feed the silkworms with leaves 4 times a day, early in the morning, at noon, in the afternoon, and at night. The amount should be appropriate each time to avoid waste. You can put more leaves at night because the silkworms eat mulberry leaves all night. Ant silkworms should be fed with young leaves, and the leaves are best cut into pieces or strips.

3. Clean up the feces and leftover leaves frequently: When changing leaves for the silkworms, you can directly cover the old leaves with new leaves, and remove the old leaves after the silkworms have crawled onto the new leaves. This can reduce the casualties of the silkworms and facilitate the removal of leftover leaves and silkworm feces.

4. Do not spray pesticides in the silkworm room as this will harm the silkworms.

5. What is the best season for raising silkworms?

Sericulture is generally carried out in spring and summer, which is roughly the same as the growth cycle of mulberry trees, to ensure an adequate supply of mulberry leaves. Sericulture is an important skill created by the working people in ancient China. It is said that the method of planting mulberry trees and raising silkworms originated from Leizu, the wife of Huangdi.

6. Can wood-crowned silkworms be bred in spring?

Wood-spined silkworms have been planted in spring

The season for raising silkworms is generally spring and summer every year. Since the main food of silkworms is mulberry leaves, the silkworm raising season and the growth cycle of mulberry trees need to be basically consistent to ensure sufficient mulberry leaves. In the silkworm areas of Jiangsu and Zhejiang, silkworms can be raised theoretically for 8 months from April to November, but only 3-5 times a year.

7. 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.

8. 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.
