Method for rearing young silkworm in constant temperature and humidity

A technology of constant temperature and humidity, breeding, applied in the field of sericulture, can solve problems such as uneven development of juvenile silkworm groups, increase of weak and small silkworms, and water imbalance of juvenile silkworms, so as to improve the labor input and output benefits of sericulture and reduce the source of disease Opportunity of transmission, effect of uniform health of juvenile silkworm population

AI Technical Summary

Problems solved by technology

These methods make the indoor temperature and humidity of juvenile silkworms fluctuate, and the deviation is large. Compared with the standard temperature, the indoor temperature fluctuates by more than 5 degrees Celsius, and the relative humidity fluctuates by more than 15% to 25%. Shriveled, the activities of various enzymes in the juvenile silkworms are affected, the water in the juvenile silkworms is unbalanced, and the physiological metabolism cannot be carried out normally, causing the development of the juvenile silkworms to be uneven, the number of weak and small silkworms increases, and the juvenile silkworms are weak and susceptible to silkworm diseases
In addition, the harmful gas leaked from the furnace body and the flue often causes poisoning of young silkworms reared indoors and even accidents of poisoning of operators

Embodiment

[0054] Example: such as figure 1 As shown, a constant temperature and humidity breeding method for juvenile silkworm silkworms, the breeding area is set in the protective tent 1, and the protective tent 1 is provided with a heating and humidifying device 2. The specific operation steps are as follows:

[0055] The first age: the dry bulb temperature is 27.6 degrees, the wet bulb temperature is 27.0 degrees, and the difference between dry and wet is 0.6 degrees

[0056] Day 1:

[0057] 8:00 Seat reservation and mulberry feeding, the amount of mulberry used is 0.10 kg / one silkworm egg, the size of cut mulberry is 2.5×0.5 cm, the area of ​​silkworm seat is 54×42 cm / one silkworm egg, and the mulberry leaf is the second leaf;

[0058] 20:00 Seat expansion, seat equalization, scorched chaff and lime, mulberry feeding, mulberry consumption 0.15 kg / one silkworm egg, mulberry cutting size 2.5×0.5 cm, silkworm seat area 64×54 cm / one silkworm egg, harvesting The mulberry leaf is the 2n...

Abstract

A constant-temp and humidify culturing method for young silkworm features that its culture region is arranged in a protecting netting, in which there are also heating moistener for precisely controlling ambient temp and humidity.

Description

technical field [0001] The invention relates to a method for raising silkworms. Background technique [0002] In rural China, sericulture production is mainly divided into three stages, that is, the stage of silkworm breeding (hatching) stage, the stage of juvenile silkworm rearing and the stage of adult silkworm rearing. The technical operations of each stage are completely different, but they are closely connected with each other. The silkworm rearing stage is an important period to enrich the body of juvenile silkworms and promote the neat development of juvenile silkworm groups. Raising juvenile silkworms is the root of harvesting high-quality silkworm cocoons. [0003] Juvenile silkworms are small silkworms of 1-3 instars. The development process of juvenile silkworms has specific biological characteristics, and the temperature and humidity of the feeding environment have direct and indirect effects on the growth and development of silkworms, especially in the 1-3 insta...
