CATDOLL : CATDOLL: New technology for silkworm breeding (new technology for silkworm breeding)

1. New technologies and methods for silkworm breeding?

1. Preparation

Before raising silkworms, be sure to prepare a clean, odor-free cardboard box, and then poke some small holes on the top of the box to facilitate ventilation.

2. Incubation

Place the silkworm eggs in a carton at a temperature of 21-29°C. The incubation time is generally about 11 days.

3. Feeding

(1) When the silkworms are about to hatch, put an appropriate amount of fresh mulberry leaves into the cardboard box for the silkworms to eat.

(2) When silkworms are in the young stage, they can be fed with fresh and tender mulberry leaves. When they are in the adult stage, they can be fed with ordinary mulberry leaves.

(3) Before feeding, be sure to check the mulberry leaves carefully to pick out diseased, moldy, and insect-infested leaves, and make sure there is no water on the leaves, otherwise the silkworms will easily suffer from diarrhea after eating them.

4. Cleaning

(1) The old mulberry leaves in the cartons must be removed regularly and replaced with fresh mulberry leaves. All silkworm feces in the cartons must be cleaned up.

(2) When changing mulberry leaves to clean the feces, you must use a brush. The silkworms on the old mulberry leaves can be gently swept onto the new mulberry leaves, and then the silkworm feces and old mulberry leaves in the cardboard box are cleaned, and finally the new mulberry leaves are put into the cardboard box.

(3) If there are dead silkworms in the carton, be sure to clean it up immediately to prevent other silkworms from being infected.

2. New technology for factory-based silkworm farming?

The biggest feature of factory silkworm farming is that silkworms are fed with artificial synthetic feed and color pigments are incorporated into the feed. Silkworms are fed feed of the desired color of silk, which reduces the number of silk dyeing processes.

3. How to breed silkworms on a large scale?

Preparation before raising

Silkworm farmers should make the following four preparations before raising silkworms.

1. Report the number of silkworms

New mulberry-planting households can report the number of silkworms when the mulberry trees are about 0.7 meters high. Old households can report the number of silkworms when the first batch of silkworms in spring and autumn is about 0.5 meters high. Other batches report the number of batches when the silkworms are received. One silkworm needs 450 to 500 kilograms of mulberry leaves, and it takes about 25 days from reporting the number of silkworms to receiving the silkworms.

2. Silkworm room

The silkworm room should have a flat and clean floor, with convection windows in front and back, preferably ground-level windows. The doors and windows should be equipped with screens to prevent flies, and the ground-level windows should be equipped with wire mesh to prevent mice. Both greenhouses and cement rooms are acceptable (cement rooms are best in cold weather, and greenhouses are best in hot weather). Raising one silkworm requires about 30 square meters of silkworm rearing area and a 10 square meter dedicated mulberry leaf room.

3. Silkworm tools and medicines

For 1 silkworm bed, you need to prepare the following silkworm tools and medicines: 15 to 20 silkworm winnowing machines with a width of 0.8 meters. Four leaf-picking baskets and about 20 square meters of medicine film. 2 to 3 pairs of slippers, placed in the silkworm room and mulberry leaf room respectively. Several red bricks, mainly for feeding silkworms when raising silkworms on the ground. Generally, 2 rows of bricks are placed in each room to facilitate walking back and forth.

2 special barrels for disinfecting silkworm rooms, 1 sprayer. Do not use barrels and sprayers that have been used to disinfect silkworm rooms. 260 square winnowing sieves. About 60 kg of lime, sprinkle a small amount of water on the silkworms 3 days before the silkworms are taken out.

3. Disinfection

Disinfection is the premise for preventing and controlling silkworm diseases and ensuring high-yield and high-quality silkworm breeding, so it must be done seriously. The first batch of disinfection should be completed within 1 week before the silkworms are received. First, thoroughly clean the silkworm room, mulberry leaf room and surrounding environment, and expose the silkworm tools to the sun, and then disinfect the silkworm room and silkworm tools. The best medicine at present is Xiaoteling.

The preparation method of Xiaoteling is: first crush the main agent, stir it into a paste with a small amount of water, then pour in 25 kg of water, then add the auxiliary agent and stir it slightly. After clarifying for 15 minutes, it can be used. Use a special sprayer to disinfect the silkworm room and all silkworm tools. The disinfection should be comprehensive and thorough. The indoor walls and floors should be sprayed evenly and thoroughly. After spraying, close the doors and windows to keep them moist for 1 hour.

After the disinfectant is completely dry, repeat the above method for disinfection once more. It is better to soak the film, shoes, silkworm tools, etc. in the disinfectant solution for disinfection. After disinfecting the silkworm room twice, open the doors and windows. Note that unsterilized items cannot be placed in the disinfected silkworm room.

Sericulture technology

1. Spray mulberry leaves to feed silkworms

Add 5 ml of fermentation liquid to 1 kg of water, spray 10 kg of mulberry leaves and add food, once a day. Silkworms love to eat, their feces are not smelly, they grow fast, their cocoons are thick and of good quality, and can increase production by about 10%.

2. Spray the silkworm body to cool down and relieve heat

In summer, the temperature is high and silkworms are prone to illness. If the room temperature is too high, silkworms are prone to heatstroke and death. In hot weather, add 5 ml of fermentation liquid to one pound of water and spray it on the silkworm body, once in the afternoon and once every day.

3. Spray mulberry leaves to keep fresh

In summer, the temperature is high, and the collected mulberry leaves will turn yellow and deteriorate if they are piled for a long time. In autumn, the climate is dry, and the collected mulberry leaves will dry and harden if they are kept for a long time. You can add 5 ml of fermentation liquid to one pound of water, use it to spray the mulberry leaves, and then put the mulberry leaves into a woven bag or pile them on the ground, cover them with plastic cloth, and they will still be as green as before after 24 hours.

4. Spray mulberry leaves to promote growth

Add 1-2 ml of fermentation liquid to one pound of water, spray it on the mulberry leaves in the mulberry field, spray 2-3 times a month, and add 0.2% phosphoric acid.

4. Sichuan sericulture technology?

1. Select a location

The planting site should be a plot with fertile soil, convenient irrigation and drainage, and flat terrain. In order to save land and improve the utilization rate of rural land, it is recommended to build a sericulture garden near the village. It is recommended to plant sericulture on a large scale and manage it in a unified manner to ensure higher returns. Large-scale and large-scale sericulture gardens are also convenient for unified management and production guidance, and implement mechanized and modernized operations and management to avoid silkworm poisoning caused by irregular management.

Sericulture has extremely high safety requirements. Sericulture gardens should be far away from pollution sources to prevent pollution from causing poor growth and development of mulberry trees and to avoid poisonous mulberry leaves that may cause poisoning of silkworms. The construction of sericulture gardens should be planned in a comprehensive manner, with reasonable arrangements for ditches, roads, canals and irrigation and drainage systems, so as to create a sericulture production park with complete functions and good ecology as much as possible.

2 Key technologies of sericulture

2.1 Site selection, land preparation and base fertilizer

Before building a sericulture garden, select a plot of land according to the actual situation, make overall planning, and do a good job of land preparation and base fertilizer treatment. The soil of the plot should be sandy loam, with a soil depth of >1.5m and organic matter in the tillage layer >1.2%, meeting the basic requirements of drought irrigation and flood drainage. If the land conditions do not meet the requirements, soil testing and formulation technology can be used to improve the land conditions, and the garden can be built after they meet the requirements.

After the garden is built and the land is prepared, 22,500 to 30,000 kg of organic fertilizer is spread per hectare of land. Then, according to the target row spacing, a planting ditch is dug with a width of 50 cm and a depth of 50 cm. In the ditch, 52,500 to 75,000 kg of organic fertilizer and 900 to 1,050 kg of superphosphate are applied. Finally, the ditch is filled with soil, mixed with fertilizer and watered. After the soil is compacted, the mulberry trees are planted in due time.

2.2 Seedling preparation

Mulberry seedlings with pure varieties, fresh seedlings, complete root systems and full stems should be selected. The main variety planted in Longchuan County is Nongsang No. 12.

2.3 Reasonable density of planting

The density of mulberry planting should be determined according to the growth characteristics of the variety, and a reasonable density specification should be selected. Within a certain density range, under the same variety and fertilizer conditions, the yield increases with the increase of density. Only by ensuring a reasonable density can a high yield of the group be ensured.

2.4 Mulberry Planting Time

The planting time of mulberry trees is divided into winter planting and spring planting. Winter planting is carried out before the leaves of mulberry trees fall or the soil freezes. Winter planting can be appropriately advanced by 7 to 10 days, but it must not be too late to prevent the mulberry seedlings from freezing. Spring planting is carried out after the soil thaws and before the mulberry trees sprout. Attention should be paid to water and fertilizer management during spring planting, especially for hilly and mountainous mulberry gardens, which should be watered in time according to precipitation conditions to prevent water shortage from affecting the growth and development of mulberry seedlings.

2.5 Mulberry Planting Methods

The planting of mulberry seedlings should follow the principle of "select, pick and sort". Select fresh and complete strong seedlings, remove incomplete seedlings, miscellaneous seedlings and weak seedlings and plant them separately. Before planting, the split roots, damaged roots, diseased and insect roots, dry roots, frost-damaged roots and long roots should be cut off and the cross-section should be sorted. If the roots of mulberry seedlings are wilted, they can be put into mud for treatment, and the roots can be restored before planting. The planting depth is based on the rhizome, and the rhizome should be buried <10cm. The generally recommended planting depth is 5 to 8cm.

After planting the sericulture seedlings, the soil should be 40cm wide and 20-25cm high. In mid-to-late March of the following year, the ridges should be leveled after irrigation between the rows. Dead seedlings should be replanted in spring, and large, strong and vigorous seedlings must be selected for replanting.

Disinfect and clean the silkworm room, install air conditioning, and feed the silkworms on time

6. How to learn the complete set of techniques for raising silkworms?

1. To raise silkworms, you must first buy silkworm seeds, which are silkworm eggs. This product has the ability to hatch silkworms. Every spring, when the temperature remains around 20 degrees, silkworms will hatch from silkworms.

2. After the silkworms hatch, you need to pick mulberry leaves to feed them. The chewing ability of silkworms is not that strong, so you should choose relatively tender mulberry leaves. There should be no water or pesticides on the mulberry leaves.

3. Silkworms can be raised in paper boxes. If the scale is larger, they can be raised in special bamboo boxes, which must be breathable, hygienic and clean.

4. Raising silkworms has relatively high requirements for the environment. There must be no fumes, no mosquitoes, no mosquito coils, no spraying of pesticides, and no dust. Otherwise, the survival rate of silkworms will be affected.

5. The process of raising silkworms is very hard. Silkworms need to eat mulberry leaves day and night, and as they grow older, the amount of mulberry leaves they eat increases.

6. Silkworms usually spin cocoons in about a month. Before spinning cocoons, we need to build a frame and let them go up the mountain. It will take about two or three days for the silkworms to spin a snow-white cocoon.

7. New technology for silkworm breeding in Hechi?

First, introduce high-quality mulberry silkworm varieties. In terms of mulberry varieties, promote and introduce mulberry "triploid", Guisangyou series, Yuesang, Husang series, etc.; in terms of silkworm varieties, introduce "Liangguang No. 2", "Guican No. 2", "Guican N2", etc., and actively carry out the transformation of medium and low-yield mulberry gardens.

The second is to promote the model of separating humans from silkworms. By promoting the model of separating humans from silkworms, it is easier to disinfect the silkworm house and prevent diseases, the silkworm breeding environment is cleaner, the success rate of silkworm breeding is greatly improved, and the income of silkworm farmers has doubled.

The third is to promote the "three-in-one" model of silkworm excrement treatment. By implementing corporate collection, harmless treatment and market-oriented marketing of silkworm excrement, silkworm excrement can be truly turned into treasure, achieving ecological, economic and social benefits.

Fourth, promote mechanized and labor-saving mulberry planting and silkworm breeding technologies to stimulate the enthusiasm of silkworm farmers. By promoting the country's leading "mechanical mulberry branch cutting", "frame stacking small silkworm co-rearing", "simple greenhouse raising of large silkworms", "labor-saving strip mulberry breeding technology", "labor-saving silkworm breeding on silkworm platforms", "track-type mulberry feeding", "automatic cocooning technology", "fast cocoon picker" and other labor-saving technologies and tools, the work efficiency and economic benefits have been greatly improved, and the enthusiasm of farmers in planting mulberry and raising silkworms has also been enhanced. Taking Huanjiang Maonan Autonomous County, which has just achieved poverty alleviation for the entire ethnic group, as an example, there are 26,322 poor households in the county, of which 6,234 are engaged in the mulberry silk industry, accounting for 23.7% of the poor households in the county.

Fifth, promote the multi-batch rolling silkworm breeding model to promote the refinement of industrial division of labor. The innovative multi-batch rolling silkworm breeding model has greatly improved the utilization rate of silkworm houses and the output of individual labor, further improved the efficiency of mulberry silkworm production, and achieved the goal of each mulberry silkworm-related practitioner getting what they deserve. This innovative silkworm breeding model requires that large and small silkworms be raised separately, and the industrial division of labor is more refined, which has promoted the healthy development of the city's silkworm industry.

Sixth, the production technology model of fresh pupa nest silk was promoted to stabilize the price of fresh cocoons. The city's 31 silk reeling enterprises took the lead in promoting the production technology of fresh pupa nest silk in the country, which played a role in reducing the collection and drying links and saving costs. The cost per ton of raw silk was reduced by 10,000 yuan compared with the traditional process, and the annual output of silk was 7,200 tons, increasing economic benefits by more than 70 million yuan, which better stabilized the price of fresh cocoons in the city.
