What willow trees are planted in the Northeast to raise silkworms, and where are there more silkworm

I pour ... It turns out that willow trees can raise silkworms...

I have seen it for a long time...

Now they all use artemisia willow to raise silkworms, and the effect is good.

Summary. Hello, glad to answer for you. The Pearl River Delta, East China Plain and Sichuan Basin are mainly concentrated in the Pearl River Delta, East China Plain and Sichuan Basin. silkworms, which are divided into two categories; A type of silkworm, that is, mulberry silkworms.

Hello, glad to answer for you. The places of silkworm cultivation in China are mainly concentrated in the Pearl River Delta, East China Pingsuiye and Sichuan Basin. silkworms, which are divided into two categories; A type of silkworm, that is, mulberry silkworms.

1. Choose a barren mountain wasteland near the gentle slope of the mountain and suitable for silkworm raising, sow acorns, and gradually cultivate it into a silkworm farm, which can not only use silkworm raising. It is also good for soil and water conservation. From mid-September to late October every year, the oak acorns are ripe, and the acorns are picked to select good acorns with large grains, plump, no insect mouth, and no odor, ready to be sown.

Remove the ground turf before sowing, dig into a soil pit, the pit is about 50 cm deep, the pit mouth is 50-70 cm, after digging the pit in the backfill of some topsoil, each pit is scattered 5-7 oak seeds, covered with soil 3-5 cm, buried well, evaporated with waterproof. 2. After planting, we should pay attention to the management of seedlings. Because the oak tree is a negative tree species, the growth is relatively slow, if the management is not good, it is easy to be bullied by grass, or by livestock to eat, resulting in undue losses.

The sowing distance should be determined according to the quality of the soil. Generally, the plant spacing is 2 meters, and the row spacing is 3 meters. The fertile soil is slightly thinner, and the poor soil is slightly denser.

It is best to divide into small areas according to the mountain conditions, and set aside the operation road in the section. Two years after sowing, when the land begins to thaw in early spring, the trunk of the tree is cut off from close to the surface with a quick pickaxe to promote its branches and leaves, improve the survival rate, prevent the appearance of small old trees, and use silkworm breeding after a certain tree potential. It is also possible to use the method of raising seedlings first and transplanting after transplanting to establish an artificial silkworm farm.

This method has a hidden advantage in improving the survival rate and preventing the lack of seedlings, but it is more labor-intensive. 3. With the different mountain terrains in various places, the direction of the silkworm farm is also different. The direction of the silkworm farm is directly related to the sunshine and temperature.

The sunshine time and high temperature of the south-facing silkworm farm are long, while the sunshine time of the north-facing silkworm farm is short and the temperature is low. The difference between sunshine time and temperature between the south-facing silkworm farm and the north-facing silkworm farm is very wide. In general, it is best to raise silkworms in the southeast silkworm farm.

During the sericulture period, it can be adjusted and used according to local conditions according to the different requirements of spring silkworms and autumn silkworms, local natural meteorological conditions, and the use of silkworm varieties. These places are suitable for silkworm farming.

Shaoxing, where I heard that every family raises silkworms I also have the QQ of two silkworm farmers in Shaoxing.

Hello, it is a pleasure to serve you and give you the following answers: How many years can the oak sapling be planted to raise silkworms? Generally speaking, the saplings can be raised after 3 years of planting.

Workaround and practice steps:1First of all, to choose the right oak sapling, generally requires a thick trunk, a wide crown, a well-developed root system, a uniform crown, smooth bark, strong branches and leaves, bright color of branches and leaves, lush branches and leaves, lush branches and leaves, dense branches and leaves, dense branches and leaves, dense branches and leaves, uniform branches and leaves, lush branches and leaves, dense branches and leaves, branches and leaves are tight, branches and leaves are green, branches and leaves are uniform, branches and leaves are lush, branches and leaves are luxuriant, branches and leaves are dense, branches and leaves are compact, branches and leaves are green.

2.Secondly, to choose a suitable planting site, it is generally required that the terrain is flat, the soil is fertile, the moisture is sufficient, the air is circulating, the sunshine is sufficient, the drainage is good, the soil is moist, the soil texture is loose, the soil depth is sufficient, the organic matter content in the soil fissure is sufficient, the nutrients in the soil are sufficient, the microbial activity in the soil is good, the moisture in the soil is sufficient, and there are few pests and diseases in the soil. 3.

Finally, it is necessary to pay attention to the management of oak trees, such as watering, fertilization, weeding, insect control, and pruning, to ensure the healthy growth of oak trees. Personal Tips:1

When planting oak saplings, it is necessary to choose the right oak saplings and choose a suitable planting location to ensure the healthy growth of the oak trees. 2.During the growth period of the oak tree, it is necessary to regularly carry out watering, fertilization, weeding, insect control, pruning and other management work to ensure the healthy growth of the oak tree.

3.After 3 years of growth, you can start raising silkworms, but pay attention to the health of the oak tree to ensure the healthy growth of silkworms.

Mulberry sapling varieties for sericulture.

Lusang, a major variety of mulberry tree, is the main cultivar in the silkworm area of China. The characteristic of Lusan is that its leaves are large, the leaf length can reach 30 cm, and it is thick and juicy, which is a rare good feed in silkworm farming. Russan loves light and has strong adaptability to climate and soil.

Hardy, can withstand low temperatures of -40, drought tolerant, not resistant to water and moisture. It can also grow in a warm and humid environment. It prefers deep, loose and fertile soil, and can tolerate mild salinity (.

Resistant to wind and toxic gases. The root system is well developed, the growth is fast, the germination power is strong, the pruning resistance is resistant, and the life span is long, generally up to hundreds of years, and individual can reach thousands of years. It is mainly cultivated in silkworm areas in Jiangsu, Zhejiang, Sichuan and Shaanxi.
