CATDOLL : CATDOLL: Which mulberry tree is good for silkworm breeding?

1. Which variety of mulberry tree is best for raising silkworms in Guizhou?

The "Guisang No. 6" mulberry variety has large leaves, which means that the leaf picking speed is fast, saving labor costs. Drought resistance means easy management, and mulberry trees are not prone to yellowing leaves. Disease resistance is very important. I am worried that mulberry trees will get sick, because silkworms dare not use pesticides at all. If the silkworms are poisoned by alcohol, it will be a big loss.

Mulberry seedling varieties for silkworm breeding

Lu mulberry is a major variant of mulberry and is the main cultivated variety in my country's silkworm areas. The characteristics of Lu mulberry are that its leaves are large, up to 30 cm long, and thick and juicy, making it a rare good feed for silkworm breeding. Lu mulberry likes light and has strong adaptability to climate and soil. It is cold-resistant and can withstand low temperatures of -40°C.

It is wind-resistant and resistant to toxic gases. It has a well-developed root system, grows fast, has strong germination ability, is resistant to pruning, and has a long lifespan, which can generally reach hundreds of years, and some can reach thousands of years. It is mainly cultivated in silkworm areas in Jiangsu, Zhejiang, Sichuan and Shaanxi.

4. How many varieties of mulberry trees are there? Are they all suitable for feeding silkworms?

Do you want to raise silkworms? The best mulberry tree for raising silkworms is: Alsophila mulberry variety has significantly higher cocoon formation rate and pupation rate for silkworms in the process of raising silkworms than other varieties. In the comparison of cocoon layer rate of silkworms, Morus altissima has the highest rate, followed by Alsophila mulberry, and the lowest is Autumn Rain, with cocoon layer rates of 18.82%, 16.54% and 14.90% respectively. There is not much difference in the survival rate of silkworms among the four varieties of mulberry trees throughout the whole age process.

The results of silkworm breeding with Alsophila chinensis and Morus altissima are quite remarkable, while the results of Mulberry chinensis and Morus altissima are relatively poor. Considering the silkworm breeding results and climatic conditions, the planting of Alsophila chinensis and Morus altissima should be further promoted on a large scale.

5. What kind of mulberry trees are used for raising silkworms?

Alsophila mulberry is suitable for silkworm breeding. Alsophila mulberry is also called Guandong mulberry, which is a Shandong mulberry species. This variety of mulberry tree has good disease resistance, and its mulberry leaves are large, thick and juicy. In addition, when this variety of mulberry leaves are used for silkworm breeding, the cocooning rate and pupation rate of silkworms are high.

6. Which variety of mulberry is the best?

1. Protein mulberry

Protein mulberry, also known as feed mulberry, is a hybrid mulberry species suitable for cultivation in northern and southern my country. After more than 20 years of breeding from more than 100 mulberry varieties across the country, scientist Mr. Bai Zhongshe has selected and bred it. It is a high-yield, high-efficiency, and high-protein hybrid mulberry tree species suitable for cultivation in northern and southern China. The protein content of protein mulberry leaves can reach up to 33%, and the protein content of branches can reach more than 20%. The leaves are edible fresh vegetables, and mulberry tea is also a pure natural drink that can reduce the three highs. The branches are the best raw material for feed plant protein.

2. Long mulberry

The dragon mulberry is a deciduous tree with yellow-brown bark. Each branch is twisted like a swimming dragon. The leaves are ovate to oval, large and shiny. The branches of the dragon mulberry are twisted, like a swimming dragon, and it is an ornamental tree. The leaves can be used to raise silkworms, and the whole plant is used as medicine.

3. Seedless large 10-fruit mulberry

Early-maturing variety, with spreading tree shape, vigorous growth and thick and long branches. Single fruit weighs 4-8 grams, purple-black, thick and seedless, sweet and juicy, known as the "excellent fresh food" fruit mulberry variety. It matures in late April to early May in Hunan, with an acreage yield of 1500-2000 kg of mulberry fruit.

4. Xiangsang No. 6

This is a triploid mulberry variety bred by Hunan Sericulture Research Institute. It has upright and thick branches and loose wood. It is an early-maturing and early-maturing variety. It is moderately resistant to mulberry yellowing atrophy disease, and has stronger resistance to mulberry thrips and mulberry borers than Husang No. 32. It has moderate drought resistance and strong adaptability.

5. Long-fruit mulberry

Long-fruit mulberry, also known as super-fruit mulberry and purple-gold honey mulberry, was introduced from Taiwan. The fruit is slender and weighs up to 20 grams. It has a beautiful appearance, good taste, sweet and non-acidic. The yield of mulberry fruit per mu is about 2,500 kilograms. It has the habit of bearing fruit in all seasons and can be planted in all parts of my country.

6. Nongsang No. 12

It was bred by the Sericulture Research Institute of the Zhejiang Academy of Agricultural Sciences and is widely planted in Zhejiang, Jiangxi, Anhui, Shandong, Hubei, Yunnan and other provinces. The tree is upright with a compact crown. It is a mid-ripening variety with a leaf yield of more than 2,600 kg per mu. The autumn leaves cap and harden late, and the leaves are of excellent quality. It is highly resistant to bacterial diseases and yellowing atrophy diseases, has a wide adaptability, and can be planted in all regions.

7. What types of mulberry leaves are used for silkworm breeding?

Silkworms eat mulberry leaves from mulberry trees, domestic mulberry trees, jing mulberry trees, and yellow mulberry trees. They are the main daily food of silkworms. These tree species are the dried leaves of plants in the mulberry family.

The leaves of the mulberry tree are broadly oval, heart-shaped, and have serrated edges.

Poplar leaves are more effective. When feeding silkworms, you need to use leaves that are neither too old nor too tender. If they are too tender, they will cause diarrhea. If they are too old, the silkworms will not eat much. It is best to pick the leaves in the morning after the sun comes out to dry the moisture on the leaves. The leaves at this time are the best. You also need to maintain a certain temperature, which is beneficial to the growth of silkworms.

8. Which mulberry tree variety has the highest and best leaf production?

Qiangsang No. 1 is a mulberry variety selected and bred by the Sericulture Research Institute of Zhejiang Academy of Agricultural Sciences. It is an excellent mulberry variety with high leaf yield and strong stress resistance. It can be planted and promoted in accordance with local conditions in the silkworm areas south of eastern China and south of the Qinling Mountains in central and western China. Its main advantages are super high yield, large and thick leaves, drought resistance, late hardening of autumn leaves, huge leaf shape so leaf picking is easy, and the growing period is from mid-to-late March to early November. At present, Qiangsang No. 1 is one of the two mulberry varieties mainly promoted in Zhejiang.

The other is Nongsang No. 14. Nongsang No. 14 is a diploid variety selected from a local variety hybrid combination of the Sericulture Research Institute of Zhejiang Academy of Agricultural Sciences. It is an early-maturing, mid-ripening, high-yield variety belonging to the Shandong mulberry system. It is planted in Zhejiang, Jiangxi, Shandong, Sichuan, Guangxi and other provinces. Its greatest advantages are its wide adaptability, early germination and strong stress resistance. Currently, Nongsang No. 14 is one of the two mulberry varieties mainly promoted in Zhejiang.
