preparation example Construction

[0046] The present invention preferably disinfects silkworm room ground, operation room ground, mulberry cutting board (or mulberry cutting machine), mulberry feeding tool, anti-drying paper, etc. every day and after desanding, which can prevent other silkworm diseases from occurring to the greatest extent. The present invention preferably uses 1% available chlorine bleaching clarification solution for disinfection. In the present invention, the preparation method of the 1% available chlorine bleaching clarified solution preferably comprises: after mixing 1 kg of bleaching powder containing 25% available chlorine with 24 kg of water, taking the supernatant solution after standing for 30 minutes.

[0047] In the present invention, during co-cultivation of small silkworms, the collection of ants and the feeding of mulberries are preferably completed on time at 8:00 in the morning, and the feeding is carried out in the morning after each sleep, which can realize 3 times of interna...

Embodiment 1

[0050] Spring silkworm period: On May 14, 2018, the greens will be replenished, the ants will be collected on May 15, and the co-cultivation will end on May 22.

[0051] 1. Replenishing greens: On the first day when the "Guican No. 13" silkworm eggs are delivered to the ant collection room, the temperature of the co-cultivation room is raised to 22°C, and the humidity is maintained at 80% to 85% (the difference between dryness and humidity is 1.5°C to 2°C). After the silkworm eggs enter the ant collection room, the temperature gradually rises to 25°C-25.5°C, and the humidity is maintained at 85%-90% (the difference between dryness and humidity is 1°C-1.5°C).

[0052] 2. Harvesting ants: When you see a small amount of seedlings in the morning, you can collect ants by photosensitive in the next morning; if you see a small amount of seedlings in the evening, you can harvest ants by photosensitive in the morning of the third day. The ants are collected by the method of mulberry, a...

Embodiment 2

[0069] Spring silkworm period: On May 14, 2018, the greens will be replenished, the ants will be collected on May 15, and the co-cultivation will end on May 22.

[0070] Small silkworm rearing

[0071] Environmental requirements: the temperature of the 1st instar silkworm is 26°C, and the humidity is 70%; the temperature of the 2nd instar silkworm is 25°C, and the humidity is 65%; 1.0~1.5℃, natural light, uniform light.

[0072] Anti-drying measures: the 2nd instar ant silkworm does not prevent dry breeding; the rest of the conditions are the same as in Example 1.

[0073] After the co-cultivation, the obtained silkworms developed more neatly, healthy and without weak silkworms.

Abstract

The invention provides a young silkworm cooperative rearing method of anti-blood grasserie silkworms, and belongs to the technical field of silkworm rearing. The method includes the steps: 1) rearingnewly-hatched silkworms at the temperature of 26-28 DEG C and the environment humidity of 70-80% after the newly-hatched silkworms grow one year old, and taking a full anti-dry measure for the one-year-old newly-hatched silkworms; 2) rearing the newly-hatched silkworms at the temperature of 25-27 DEG C and the environment humidity of 65-75% after the newly-hatched silkworms grows two years old, and taking a half anti-dry measure for the two-year-old newly-hatched silkworms; 3) rearing the newly-hatched silkworms reaching three years old at the temperature of 24-26 DEG C and the environment humidity of 65-70% until three-year-old newly-hatched silkworms are secondly fed with leaves or four-year-old newly-hatched silkworms are firstly fed with leaves, and taking no anti-dry measure for the three-year-old newly-hatched silkworms. According to the young silkworm cooperative rearing method, the anti-blood grasserie silkworms grow uniformly and are healthy, weak and small silkworms are avoided, cooperative rearing of the newly-hatched silkworms is implemented at the provided temperature and the provided humidity, growth of the newly-hatched silkworms can be accelerated, cooperative rearing is completed within a short time, and the risk of infection with other silkworm diseases of the newly-hatched silkworms is reduced.

Description

technical field [0001] The invention belongs to the technical field of silkworm breeding, and in particular relates to a co-cultivation method for small silkworms resistant to blood-type concentrated disease silkworms. Background technique [0002] Bombyx mori nuclear polyhedrosis (commonly known as blood type pustosis) caused by silkworm nuclear polyhedrosis virus (BmNPV) is currently the most serious silkworm disease in sericulture production, and it occurs in all major silkworm areas in the country, especially in Sericulture in summer and autumn accounts for about 70% of silkworm disease losses, which has seriously affected the sustainable development of the industry. "Guican No. 13" has the characteristics of high silk production, fast growth and resistance to silkworm virus disease (NPV). However, this variety has strong resistance to NPV, and its resistance to other pathogens is not outstanding, especially when the breeding environment, leaf quality, temperature and h...
