CATDOLL : CATDOLL: What trees are needed for silkworm breeding (What tree species are needed for silkworm breeding)

1. How many years does it take to start raising silkworms on one acre of newly planted mulberry trees?

One mu of mature mulberry forest can raise silkworms for 2-4 seasons a year, raising 4-6 cocoons, each of which can produce about 50 kg of fresh cocoons. Based on the average market price of 40 yuan per kilogram this year, the output value per mu is 4×50×40=8,000 yuan, with costs of 200 yuan for silkworm seeds and 100 yuan for disinfectants, a total of 300 yuan. Mulberry gardens can be used comprehensively, such as raising chickens and intercropping peanuts to increase economic income.

2. What trees do silkworm pupae eat?

The staple food of silkworm pupae is mulberry leaves, but you can feed them wolfberry leaves, lettuce leaves, elm leaves, oak leaves and lettuce leaves, but not too much. Silkworms can eat a lot of food, in addition to mulberry leaves, there are jujube leaves, elm leaves, fig leaves, wormwood leaves, dandelion leaves, lettuce leaves, romaine lettuce leaves, salsify leaves, etc. There are no less than twenty kinds.

Silkworms love to eat mulberry leaves the most. This is because silkworms spend the most time eating mulberry leaves. As they reproduce on mulberry trees from generation to generation, they gradually develop the habit of eating mulberry leaves, and it becomes hereditary.

3. 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.

4. What are the advantages and disadvantages of mulberry wood?

Mulberry belongs to the genus Morus, a deciduous tree. The tree can reach a height of 20m and a breast diameter of 1m. There are many varieties. Because the leaves are used to feed silkworms, they need to be pruned every year, so the tree is not actually very tall. The tree grows fast, has strong adaptability, and is widely distributed, from south of Harbin, Heilongjiang in the north, southern Inner Mongolia, to Guangdong and Guangxi in the south. From Taiwan in the east to Sichuan, Yunnan, and Xinjiang in the west, it is most cultivated in the Yangtze River Basin and the middle and lower reaches of the Yellow River Basin.

The wood is hard, durable, termite-resistant, with beautiful texture, glossy planed surface, ring-porous, yellow-white or yellow-brown sapwood, orange-yellow to golden heartwood, which turns darker and dark brown after long exposure to air, with straight texture and medium and uneven structure. Air-dried density 0.671g/cm3; shrinkage coefficient: radial 0.

142%, tangential direction 0.266%; compressive strength along the grain 47.4MPa, static bending strength 97.6MPa, flexural modulus 10.2×103MPa, tensile strength along the grain 141.9MPa; hardness: end face 68.0MPa, radial face 59.7MPa, tangential face 60.

Mulberry wood can be used to make furniture, musical instruments, handles for farm tools, and decorative materials. Its branches can be used to weave baskets, its bark can be used to make paper, and its berries can be used as medicine.

5. What are the requirements for planting loquat trees?

1. Choose land with good fertilizer and water conditions, giving priority to mature, fertile, deep, flat soil with sloping land or semi-dry paddy fields that can be irrigated and drained.

2. It is not suitable to plant crops near factories. Tobacco cannot be planted nearby and crops must be kept at a certain distance from rice and orchards to avoid contamination of mulberry leaves by spraying pesticides, which may cause poisoning of silkworms.

3. Before planting, deep plowing and maturation should be carried out, 5 to 8-inch furrows should be dug, and sufficient base fertilizer should be applied. It is required to apply 50 to 60 dan of ash manure per mu. After application, cover with a layer of about 3 inches of topsoil and mix appropriately to avoid burning the roots.

4. The best planting time: December to March every year.

5. Planting specifications: About 6,000 plants are planted per mu on sloping land, with a row spacing of 2.1 feet and a plant spacing of 5 inches; about 5,000 plants are planted per mu on semi-arid paddy fields, with a row spacing of 2.4 feet and a plant spacing of 5 inches.

6. How many mulberry trees can be planted on one acre of land?

The suitable planting density of common silk cocoon breeding and leaf mulberry garden is about 5,000 plants per mu. Single row planting: row spacing 70-80cm, plant spacing 15-20cm; double row planting: wide row 90-100cm, narrow row 40-50cm, plant spacing 15-20cm. The number of mulberry gardens harvested from strips is about 7,000 plants per mu. At the same time, grafted mulberry seedlings can generally be planted with 1,332 plants per mu, with a plant spacing of 50cm and a row spacing of about 100cm; while hybrid mulberry seedlings are suitable for planting 5,000-7,000 plants per mu, with a plant spacing of 12-18cm and a row spacing of about 65-80cm.
