What is the growth environment of silkworms?

After receiving the silkworm eggs, put the silkworm eggs into the prepared silkworm egg box, which is usually made of ordinary paper boxes, but make sure that the silkworm egg box is clean and free of peculiar smell. Silkworm eggs naturally hatch into silkworm ants at room temperature of 2 1-29 degrees Celsius for about 1 1 day (including delivery time). Silkworm ants have an appetite about 40 minutes after hatching, and the feeding process is about to begin. Take the prepared fresh mulberry leaves out of the refrigerator, and when the mulberry leaves return to normal temperature, cut them into small pieces with a knife and put them in a silkworm box, and the silkworm ants will automatically climb onto the mulberry leaves to eat. Silkworms generally need about 27 days (5 instars) from hatching to cocoon formation in the mountains. One to three-year-old silkworms should choose tender mulberry leaves to feed, and four to five-year-old silkworms can be fed with ordinary mulberry leaves. Silkworms are suitable to grow in the environment with the temperature range of 22-29 degrees Celsius, and the most suitable growth temperature is about 27 degrees Celsius. A silkworm eats about 25 grams of mulberry leaves in its lifetime. If you feed 40 silkworms, you only need 1 kg of mulberry leaves. But in the actual feeding process, a part of mulberry leaves will be wasted, so more mulberry leaves are needed. Silkworms should stop eating mulberry leaves after the age of five and start looking for suitable places to spin silk and cocoon (also called mountain cocoon). In rural areas, grass mounds or pine branches made of straw are generally used as silkworm mounds. Silkworms fed as pets can be replaced by a carton divided into many compartments. Matters needing attention in sericulture 1. Preservation of mulberry leaves 1. Put mulberry leaves in the freezer (about 5 degrees Celsius) to prevent deterioration. 2. Tighten the plastic bag mouth to slow down the drying and dehydration time of mulberry leaves. Second, silkworm feeding 1, mulberry leaves taken out of the refrigerator, need to wait for a few minutes, let the mulberry leaves return to normal temperature before feeding. 2. Don't wash mulberry leaves and keep them in a natural state. 3.
