What can be used instead of mulberry leaves to feed silkworms? Which mulberry leaves should not be f

Lettuce leaves, cinnamon leaves, elm leaves, duck onions, dandelions, lettuce leaves, etc.

The staple food of silkworms is mulberry leaves, and some other leaves can also be used (oak trees, oak trees can also raise silkworms). Silkworms have a strong appetite, they eat mulberry leaves day and night, so they grow very quickly, and there is an idiom to nibble at whales. In addition, silkworms are very afraid of cold, the temperature is slightly lower may be cold to death, we must pay attention to room temperature to keep warm, silkworms are also a delicacy of ants, but also need to pay attention to the threat of ants to the life of silkworms.

Precautions for sericulture:

1. Choose silkworm varieties with strong disease resistance. It has been bred with special varieties resistant to chlorine and pneumatosis, and suitable silkworm varieties can also be selected according to the comprehensive analysis of the actual situation of climate, geographical conditions, and common diseases.

2. Reasonable layout of sericulture. Staggering the planting and harvesting seasons of different crops, reasonably arranging the layout of silkworm raising, avoiding overlapping silkworm periods, and ensuring the input of manpower and material resources during the silkworm period, can effectively guarantee the bumper harvest of silkworm raising.

3. Manage the mulberry garden well and treat insects in time. Improving leaf quality is conducive to improving the physique of silkworms, reducing the damage of diseases and insects, and reducing the infection of silkworms by diseased insects in the wild.

4. Feed management according to the physiological characteristics of silkworms at different stages of development. The appropriate temperature and humidity standards are: 27 1 for 1 2 years old, about 1 dry and wet difference; 3rd instar 26 1, about wet and dry difference; Silkworms use 25 24, dry and wet difference about 2.

Use suitable mature leaves, remove sand frequently, ventilate regularly, sleep when full, feed in a timely manner, operate briskly, protect the silkworm body, and try to avoid wet leaves and withered leaves.

Leaf of Horn, elm leaves, fig leaves, artemisia willow leaves, dandelion leaves can be used instead of mulberry leaves to feed silkworms, and Southwest Agricultural University has developed an artificial feed that can replace mulberry leaves.

This kind of feed is prepared according to the main nutrients of mulberry leaves, and is prepared by a certain proportion of soybean cake, bean dregs, starch, sugar, cellulose, vitamins and other raw materials.

Experiments have proved that silkworms that eat this artificial feed are the same as silkworms that eat mulberry leaves from development, growth to silkworming. The color of the silk it spits out is whiter than that of silkworms that eat mulberry leaves, and the yield and quality of silk are no different from those of normal silkworms.

Precautions for raising silkworm babies.

1. Do a good job of disinfection before raising silkworms to reduce the incidence of silkworms.

Cleaning and disinfection before raising silkworms is the most important part of the whole disease prevention and disinfection work, and it is also a prerequisite for obtaining high yield of silkworm cocoons. In order to improve the disinfection effect, it is necessary to achieve "one sweep, two washes, three scrapes, four eliminations, and five whitewashing" in the disinfection steps; In the process of disinfection, it is required to achieve six requirements: the silkworm room should be cleaned, the silkworm tools should be cleaned, the medicine should be accurately dispensed, the liquid medicine should be sprayed evenly, the room should be completely eliminated, and the sterilization should be kept.

2. Do a good job of supplementing and promoting youth and improve the one-day hatching rate.

The quality of the work of supplementing and promoting greening, directly related to the level of the one-day hatching rate, the majority of silkworm farmers should pay attention to the work of supplementing and promoting greening, mainly do a good job in temperature and humidity control and shading work and other measures. After the silkworm seed arrives in the room, it is necessary to spread the eggs in time, and control the temperature 78 79, the humidity difference 2, to the evening before the ant harvest, the temperature will rise to 80 81, the humidity difference 1, and at the same time in the supplement to promote the green to be strictly darkened, in order to achieve the purpose of hatching.

Silkworms can be fed with lettuce leaves, sagebrush leaves, elm leaves, duck onions, dandelions, and lettuce leaves instead of mulberry. The staple food of silkworms is mulberry leaves, and some other leaves can also be used; Silkworms have a strong appetite, they eat mulberry leaves day and night, so they grow very quickly, and there is an idiom to nibble at whales. In addition, silkworms are very afraid of cold, and the temperature may die if the temperature is slightly lower, so it is necessary to pay attention to room temperature to keep warm; Silkworms are a delicacy of ants, and it is necessary to pay attention to the threat of ants to the life of silkworms.

Silkworm: Silkworm moth is a kind of insect, native to China, domesticated and raised indoors, so it is also called silkworm. Silkworm raising and the use of silk is a major event in human life, which has been recorded in China about 4,000 years ago, and at least 3,000 years ago, China has begun to raise silkworms artificially.

In 551 AD, two foreign monks brought cocoons to Europe. The body of the moth is medium-sized, the antennae of both female and male are ctenoid, and the male has slightly longer ctenodonate; The beak is vestigial, the lower lip is short, there is no single eye, the body wings are grayish-white, and the wing veins are grayish-brown. When the silkworm spins the silk cocoon, the head keeps swinging, and the silk is woven into neatly arranged zigzag silk circles.

Every time you weave more than 20 silk loops (called a silk column), you will move the position of your body, and then continue to spit and weave the silk column below. After one end is woven, the other end is woven, so the cocoon of the silkworm is always thick at both ends and thin in the middle. For each cocoon, silkworms need to change their position 250 500 times to weave more than 60,000 figure-8 silk loops, each of which is on average long, and the silk length of a cocoon can reach 1500 3000m.

The secretions in the silk glands are completely exhausted, and the pupa turns into a moth.

After the silkworms hatch out in spring, the mulberry leaves have just sent out a little sprout, and they are not yet, this time is the period of scarcity of mulberry leaves. When I raised silkworms, there were very few people who planted mulberry leaves there, so we basically went to steal mulberry leaves planted by others. But at this time, the mulberry leaves basically have a little tip, which is not enough at all, so it must be temporarily replaced with other foods.

At that time, the most used food to replace mulberry leaves was lettuce leaves, because lettuce grew more lush in spring, and the silkworms had just hatched at this time, and they were still very small, so they had to choose very tender leaves. It should also be noted here that the leaves must have not been sprayed with pesticides, and there is no water on the surface, and they can only be eaten by silkworms after drying. Otherwise, once the little silkworm has diarrhea, it will definitely die.

After a few days, after the mulberry leaves grow, you can just eat the mulberry leaves.

Of course, in addition to lettuce leaves, we can also replace mulberry leaves with fig leaves, lettuce leaves, dandelion leaves, elm leaves, and many more. Therefore, the growth of silkworms can not only rely on eating mulberry leaves, but it is best to use mulberry leaves, if the mulberry leaves have not grown, they can be temporarily replaced by other foods.

It can be used in place of: elm leaves, elm leaves, lettuce leaves, fig leaves, lettuce leaves, brahmana ginseng leaves, dandelion leaves, elm leaves, etc.

Mulberry silkworm introduction: also known as silkworm, one of the economic insects that spin silk and form cocoons with mulberry leaves as food.

The following mulberry leaves cannot be fed to silkworms: 1. Leaves with insufficient sunlight. Mulberry trees planted too densely, or planted in shade ground, mulberry leaves are not enough sunlight for a long time, used to feed silkworms, silkworms grow slowly, weak physique, and are easy to induce silkworm disease.

2. Immature leaves. Mulberry leaves are immature, contain more water, less dry matter, and more organic acids, and are used to feed silkworms, which will make silkworms malnourished, weak physique, and easy to induce pus and softening disease.

3. Drought-damaged leaves. The weather is dry for a long time, and the moisture and nutrient content of mulberry leaves decrease, and the fiber increases. This kind of mulberry leaf is difficult to meet the needs of silkworm growth, which will significantly reduce the blood water content of silkworm body and cause silkworm disease.

Fourth, over the old leaves. The water content of mulberry leaves is less than 70%, and the hand pinching will be broken for the aging leaves, the old hard leaf silkworms are not easy to eat, and they are also difficult to digest, and the silkworms are slow to grow and lose weight due to lack of nutrition.

5. Withered leaves. The water loss rate of mulberry leaves in the process of transportation and storage is 10% to 20%, and the amount of food eaten by silkworms will be significantly reduced, resulting in slow growth. 6. Pests and diseases.

Mulberry leaves infested by pests and diseases are accompanied by various pathogens, which can cause silkworm diseases and reduce the yield of silkworm cocoons.

Silkworms are insects that use mulberry leaves as their main food, and the quality and quantity of mulberry leaves are very important for the growth and development of silkworms in the process of raising silkworms. If the mulberry leaves are insufficient or of poor quality, it will affect the growth and development of silkworms, and the mass residue will affect the yield and quality of silk. In general, the mulberry leaves eaten by silkworms can be replaced by the following methods:

1.Mulberry twigs, petioles and leaves: In the case of insufficient mulberry leaves, the twigs, petioles and young leaves of mulberry trees can be taken instead of mulberry leaves to feed silkworms.

However, the protein content of these foods is not low, and the protein supply needs to be increased. 2.Rice stalks, corn stalks and other plant stalks:

These plant straws contain more cellulose and hemicellulose, but the protein content is low, and protein supplementation is required. 3.Artificial feed:

In the case of insufficient substitute food such as mulberry leaves, artificial feed can be used to feed silkworms, which can add protein, carbohydrates, fats and other nutrients according to the needs of silkworms, but pay attention to the selection and ratio of feed to ensure the balance of nutrition. It should be noted that none of the above substitute foods can completely replace mulberry leaves, and different substitute foods have different effects on the growth and development of silkworms, so it is necessary to pay attention to controlling the amount and frequency of feeding when using substitute foods to ensure that the growth and development of silkworm oranges or sodium are normal.

Summary. The foods that can be fed to silkworms instead of mulberry leaves include lettuce leaves, lettuce leaves, tuoshu leaves, fig leaves, elm leaves, and dandelion leaves. Although mulberry leaves are the most suitable natural food for silkworms, if environmental conditions do not allow, other leaves can be used instead of mulberry leaves to feed silkworms.

The food that can be fed to silkworms instead of mulberry leaves includes lettuce leaves, lettuce leaves, Haohengtuo leaves, fig leaves, elm leaves, and dandelion leaves. Although mulberry leaves are the most suitable natural food for silkworms, if environmental conditions do not allow, you can choose to feed silkworms with other leaves instead of mulberry leaves.
