CATDOLL : CATDOLL: Is it possible to plant oak trees and raise silkworms on flat land?

1. Is it possible to plant oak trees and raise silkworms on flat land?

Planting oak trees on flat land for silkworm rearing is possible. It is feasible. At present, in some places where oak silkworms are reared, the phenomenon of insufficient oak trees is quite common. It is necessary to insist on replanting oak trees to improve the utilization of oak silkworm farm resources and the cocoon production per unit area of ​​silkworm farm year by year, and at the same time improve the ecological environment of oak silkworm farms. Oak trees belong to the genus Quercus of the Fagaceae family. They are deciduous or evergreen trees, and a few are shrubs. The leaf margins are serrated, and few are entire. The male flower catkins are drooping, and the female flowers are solitary in the involucre. The nuts are solitary, the inner wall of the pericarp is hairless, and the undeveloped ovules are located on the outside of the seed base. The trunk is peculiar and vigorous, the tree shape is beautiful and varied, the branches and leaves are luxuriant, it is resistant to pruning and easy to shape, and the crown is like a canopy after being shaped by pulling.

2. Is mulberry tree the main food for silkworms?

Silkworm: Also known as Bombyx mori, it is one of the economic insects that spins silk and spins cocoons on mulberry leaves. Silkworms are oligophagous insects. In addition to mulberry leaves, they can also eat dead leaves, elm leaves, duck onions, thin dandelions and lettuce leaves. Mulberry leaves are the most suitable natural raw material for silkworms.

The tussah silkworm is an insect that spins silk and spins cocoons and feeds on tussah leaves.

Castor silkworm: one of the economic insects that spins silk and cocoons based on castor leaves.

Cassava silkworm: When castor silkworms use cassava as feed, they are commonly called cassava silkworms in production. In fact, they are castor silkworms.

Cordyceps silkworm: When castor silkworms use Cordyceps mulberry leaves as feed, they are commonly known as Cordyceps silkworms in production.

Silkworm: One of the economic insects that spins silk and makes cocoons by feeding on the leaves of plants of the genus Quercus in the Fagaceae family, such as the leaves of Quercus liaodongensis, Quercus mongolica, Quercus shuanpiensis, and Quercus acuminata.

Huili silkworm: When castor silkworms use mulberry leaves as feed, they are commonly known as mulberry silkworms in production.

Amber silkworm: One of the economic insects that feed on nanmu leaves and spin silk cocoons, also known as Assam or Mujia silkworm.

Chestnut silkworm: one of the economic insects that spins silk and makes cocoons with walnut leaves and chestnut leaves as its main food.

Cathayana silkworm: An economic insect that spins silk and makes cocoons, whose staple food is the leaves of Cathayana (Ailanthus toonae), and also eats the leaves of Tung oil tree, castor oil plant, holly, Michelia, Paulownia, sycamore, camphor tree, etc.

Attacus a tlas Linnaeus: One of the economic insects that spins silk and makes cocoons, belonging to the order Lepidoptera, family Bombyx mori, scientific name Attacus a tlas Linnaeus. Also known as the big mountain silkworm and the big black tallow silkworm.

Silkworm: Mainly feed on leaves of willow, maple, Chinese tallow tree, camphor, paulownia, etc.

Mulberry leaves are the main food of silkworms. In addition to mulberry leaves, they will also eat elm leaves, lettuce leaves, and even cabbage leaves when they are hungry.

Mulberry leaves are the main food of silkworms. In addition, silkworms also eat other leaves when mulberry leaves are not available. Common ones include lettuce leaves, but they don't like them very much.

Silkworms only eat mulberry leaves.

Yes, mainly mulberry and oak,

Mulberry trees are southern species, and oak trees are northern species.

If you don't look closely, they are almost identical and have the same uses. They are both used to raise silkworms.

The fruit of the mulberry tree is plump and can be eaten, while the fruit of the oak tree is dry and cannot be eaten.

I live in Jilin Province and have never seen mulberry trees, but oak trees are everywhere in the mountains and are used for burning firewood, making furniture and raising silkworms.

The method of raising silkworms with oak trees is to plant them on a large scale on the hillsides, and when the trunks are thicker than the wrist, they are cut down and burned as firewood. Only young oak trees can be used as feed.

If you see a large area of ​​oak trees on a barren hillside, and they are very small, like shrubs, then it must be a place where silkworms are raised.

3. What is the function of the fake tree?

Oak

The oak tree is also known as oak, Mongolian oak, oak, Mongolian oak, Cyclobalanopsis oak, and Cyclobalanopsis glauca.

Oak is a general name for plants of the genus Quercus in the Fagaceae family, usually referring to Mongolian oak. The tree has a unique and vigorous trunk, a beautiful and varied tree shape, luxuriant branches and leaves, is resistant to pruning and easy to shape, and has a canopy-like crown with various shapes and unique charm. It is a fine tree species for landscape gardens, courtyards and villa areas.

In addition to its leaves being used to feed silkworms, the wood of oak trees is strong and resistant to decay, and is widely used in construction. It can also be processed to make furniture and burn charcoal. Oaks contain a lot of starch and can be used to make oak wine, alcohol, starch, rubber oil, etc. It can also be used as feed. Tannin extracted from oak bark, leaves, cupules, and oaks is a necessary material for the leather industry, printing and dyeing industry, and fisheries. The cork bark has a thicker cork layer and can be used as industrial cork material. Oak wood can also be used to cultivate a variety of edible fungi such as black fungus, shiitake mushrooms, and cordyceps militaris.

feed

Oak leaves contain water, protein, carbohydrates, fat, ash, cellulose and other ingredients, which oak silkworms like very much.

The plants used for raising tussah silkworms in China belong to the genus Quercus of the Fagaceae family (see Quercus). Its leaves are the main food for tussah silkworms. The main tree species for raising tussah silkworms are Liaodong oak, Quercus acutissima, Quercus mongolica and Quercus variabilis. In addition, Quercus borax, Quercus acutissima and Quercus serrata can also be used for raising tussah silkworms. Liaoning, Henan, Shandong, Jilin, Heilongjiang and Guizhou provinces in China are the main production areas for raising tussah silkworms using oak trees. The oak trees used for raising tussah silkworms must be cultivated and pruned to make the spacing between plants and rows appropriate and the tree shape short, so as to become a tussah silkworm farm. The tree shape is divided into two types: trunkless tree shape and medium-trunk tree shape. The medium-trunk tree shape is better, with a large and evenly distributed crown, high space and light energy utilization, high and stable leaf production, and thicker leaves. The main oak leaf disease is powdery mildew, which can be controlled by pesticides. The pests that feed on oak leaves are mainly the larvae of the gypsy moth, tent caterpillar, oak flour moth, and yellow two-star moth.

Food

After processing, oak leaves have been completely transformed into "edible-grade wrapping paper". The advantage of oak leaf-wrapped food lies first in its taste: hygienic, natural, non-polluting and environmentally friendly. Therefore, people from Henan or western Henan should have oak leaf rice dumplings. As people are increasingly eager to return to nature, oak leaf-wrapped rice dumplings give people a refreshing feeling.

Medicinal

Oak bark has the effect of astringing, stopping diarrhea and treating dysentery, so it is included in the drug materials in hospitals.

Oak wood is a strong and decay-resistant material, and its bark, leaves, cupules and extracts are essential materials for leather making, dyeing and printing, and fisheries.

The cork bark of oak tree is thicker and can be used as industrial cork material. Oak tree leaves contain water, protein, carbohydrates, fat, ash, cellulose and other ingredients, which can be used to raise silkworms. The fruit contains more starch, which can be used to make oak wine, alcohol, starch, rubber oil, etc., and can also be used as feed. Tannin extracted from oak bark, leaves, cupules and acorns is a necessary material for the leather industry, printing and dyeing industry and fishery. The cork bark is thicker and can be used as industrial cork material. Oak tree can also cultivate a variety of edible fungi such as fungus, shiitake mushrooms and cordaria.

4. Why can’t we raise silkworms at home?

Silkworms cannot be raised at home because they have high requirements for the environment and temperature and like to eat fresh mulberry leaves. If the home cannot meet the silkworms' needs, it will lead to large-scale death. Silkworms are insects of the order Lepidoptera, native to China. Their life cycle includes four growth stages: silkworm seeds, silkworm ants, silkworm pupae, and silkworm moths.

The reason why silkworms cannot be raised at home is that silkworms have high requirements for climate, humidity and temperature, and their needs cannot be met at home, which will lead to their death. In addition, silkworms like to eat fresh and pesticide-free mulberry leaves, and the mulberry leaves cannot contain moisture or be too dry, so as to avoid the death of the silkworms.

Morphological characteristics of silkworms: Silkworms are animals of the family Bombyx moth in the order Lepidoptera. Their life cycle is divided into four growth stages: silkworm eggs, ant silkworms, silkworm pupae and silkworm moths. Silkworm eggs are smaller and look like sesame seeds. Ant silkworms have black bodies and look similar to ants. Silkworm pupae are made of silk spit out by silkworms, and silkworm moths are shaped like butterflies.

Silkworm's living habits: Silkworms are metamorphosed insects, the most common of which are mulberry silkworms, which mainly feed on mulberry leaves and are suitable for living in an environment of 20-30 degrees. Silkworms need to shed their skin four times, each time taking about a day, and it takes more than fifty days for a silkworm egg to transform into a silkworm moth.

Introduction to silkworm varieties There are many varieties of silkworms, which are divided into mulberry silkworm, tussah silkworm, castor silkworm, cassava silkworm, Huili silkworm, horse silkworm, amber silkworm, natural silkworm, chestnut silkworm, etc. Among them, tussah silkworm is an insect that feeds on oak leaves and is mainly distributed in China, and castor silkworm is an insect that feeds on castor leaves.
