Problems solved by technology

[0009] The traditional castor silkworm farming method is to directly feed fresh castor leaves after picking them, but the growth rate of castor silkworms is slow, the quality of cocoons is also poor, and the silk spun out by silkworms is thinner and has poor toughness. It is because the growth of castor silkworm is directly related to environmental conditions such as food, temperature, and humidity. Under suitable environmental conditions, silkworms can grow and develop normally, but under unsuitable environmental conditions, silkworms grow poorly, become weak and sick, and even die

Embodiment 1

[0040] A kind of culture method of castor silkworm of the present embodiment, comprises the steps:

[0041] (1) Select castor silkworm eggs and soak them in an aqueous solution of vitamin C at 15°C for 5 minutes and then take them out. The mass fraction of vitamin C in water is 2%, and put them into a wooden box for incubation. Spread a layer of 0.6 cm thick lime powder, the temperature in the wooden box is 29 ℃, and the humidity is 63%, to obtain the ant silkworm;

[0042] (2) the ant silkworm that obtains is put into the container that has castor leaves, and castor leaves are sprayed with 75% alcohol to sterilize, and the temperature in the container is 25 ℃, and humidity is 65%, and castor leaves are collected from 8 month, for feeding;

[0043] (3) Sterilize the container every 2 days, and clean up the leftover residue in time, and cocoons can be formed in 22 days.

Embodiment 2

[0045] A kind of culture method of castor silkworm of the present embodiment, comprises the steps:

[0046] (1) Select castor silkworm eggs and soak them in an aqueous solution of vitamin C at 17°C for 8 minutes and take them out. The mass fraction of vitamin C in water is 3.5%, and put them into a wooden box for incubation. Spread a layer of 0.7 cm thick lime powder, the temperature in the wooden box is 30 ℃, and the humidity is 65%, to obtain the ant silkworm;

[0047] (2) the ant silkworm that obtains is put into the container that has castor leaves, and castor leaves are sprayed with 75% alcohol to sterilize, and the temperature in the container is 26.5 ℃, and humidity is 68%, and castor leaves are collected from 9 month, for feeding;

[0048] (3) Sterilize the container every 3 days, and clean up the leftover residue in time, and cocoons can be formed in 20 days.

Embodiment 3

[0050] A kind of culture method of castor silkworm of the present embodiment, comprises the steps:

[0051] (1) Select castor silkworm eggs and soak them in an aqueous solution of vitamin C at 20°C for 10 minutes and then take them out. The mass fraction of vitamin C in water is 5%, and put them into a wooden box for incubation. Spread a layer of 0.8 cm thick lime powder, the temperature in the wooden box is 31 ℃, and the humidity is 68%, to obtain the ant silkworm;

[0052] (2) the ant silkworm that obtains is put into the container that has castor leaves, and castor leaves are sprayed with 75% alcohol to sterilize, and the temperature in the container is 28 ℃, and humidity is 70%, and castor leaves are collected from 8 month, for feeding;

[0053] (3) Sterilize the container every 2 days, and clean up the leftover residue in time, and cocoons can be formed in 22 days.

Abstract

The invention discloses a breeding method for castor silkworms. The breeding method for castor silkworms includes the following steps that (1) castor silkworm eggs are selected and put into a water solution of a vitamin C at the temperature of 15 DEG C to 20 DEG C, and are soaked for 5 min to 10 min to be taken out, the obtained castor silkworm eggs are put into a woody box and incubated, and newly-hatched silkworms are obtained; (2) the obtained newly-hatched silkworms are put into a container with castor leaves and are fed; (3) the container is sterilized and disinfected every 2 days to 3 days, leftover residues are cleaned in time, and cocooning can be carried out after 18 days to 22 days. According to the breeding method, the castor silkworm eggs are soaked in the water solution of thevitamin C, and are supplemented with the vitamin C, growth of silkworm eggs is facilitated, the growth cycle of the castor silkworms is short, illness is not prone to occurrence, and the incidence rate is low; fresh castor twigs are also added, experiments show that breeding time can be shortened, and meanwhile the quality of obtained silkworm cocoon products is improved.

Description

technical field [0001] The invention belongs to the technical field of insect breeding, and in particular relates to a method for cultivating castor silkworms. Background technique [0002] Castor is one of the top ten oil crops in the world. In my country, castor is a small oil crop. The annual planting area is only about one tenth of that of peanuts. The main planting areas are Taonan and Tongyu, Jilin, Northeast, and Luliangxing County and Linxian County, Shanxi. Tongliao region of Inner Mongolia. In recent years, due to the sluggish trend of oil prices and the continuous suppression of India, the largest producer of castor oil, the castor oil market in China has been hovering at a low level, seriously affecting the enthusiasm of farmers to plant castor. The castor planting area is shrinking year by year, and the supply of raw materials is critical Insufficient, import pressure is increasing year by year, the living environment of downstream castor oil processing enterpri...
