First, push the green off: silkworm silkworm seeds after drying, can be in the 24 °C -27 °C temperature and 75% -85% relative humidity within the green, the early temperature can be low, later slightly higher. If the temperature is lower than 24°C in the late period, the temperature shall be promptly replenished; in the case of high humidity and sweltering, the lime block may be placed indoors to absorb moisture, or the air may be blown with a fan to reduce the damage caused by high temperature and humidity.
Second, the small silkworm off: summer and small silkworm mulberry leaves the standard is: leaves slightly yellow wrinkled for the receipt of ants on the same day leaves; leaf color to green, the leaves are flat for the 1st age leaves; leaf color green is 2 Age-use leaves; dark green leaves, hard-to-touch hands, 3rd age leaves.
Third, feeding off: summer and autumn silkworm development is fast, in order to make silkworms satiety, must be three thin. That is, silkworm silkworm silkworm indoor (or silkworm silk Taiwan) is thin, silkworm silkworm foil on the silkworm shelf is thin, and silkworm head in the silkworm silk foil is thin. The number of mulberry leaves per day is increased by one time compared with the spring season. When the temperature is high and dry, the amount of mulberry should also be increased, and the mulberry should be thin and even, so that the larvae can eat more fresh leaves, and the moisture content of the mulberry leaves in summer and autumn is low. The moisture of the silkworm body evaporates quickly. According to the growth and development of the larvae and the external environment, the mulberry leaves should be sprinkled with water. Feeding leaves method: feed at noon, feed in high temperature and dry weather, feed more in silkworm stage, feed more during the feeding period, and feed the leaves more hard.
4. Environment: In the summer and autumn, silkworms should be cooled in a arbor. The pergola is 0.7 meters higher than the eaves, and the straw curtains are insulated. The boring bed is sprayed with well water and cooled. Noon high temperature sprays the straw on the outdoor walls and around the pergola. Water, open doors and windows when the temperature drops at midnight. When the humidity is high, dry the material on the silkworm seat, put the thin silkworm seat, increase the number of sand removal, reduce the daily amount of mulberry, increase the number of sang every day, and avoid eating wet mulberry leaves.
V. Prevention and control of diseases: The disinfection work before silkworm rearing should adhere to: cleaning, flushing silkworm silkworms, washing silkworms, indoor soil changing, pouring lime slurry on the ground, painting lime water on all sides, and using silkworm nets and other small silkworms to cook. And sun, strict disinfection. The sericulture process should:
(1) After each sleeping net is boiled and disinfected once; (2) After the three sleeps, the silkworm used by the small silkworm is fully disinfected once; (3) The fresh lime powder is disinfected every day for silkworm nest disinfection; (4) Bacteria and pesticides are contaminated The mulberry leaves and worm leaves, etc., are sterilized with bleaching solution with available chlorine of 0.3%, and the stored mulberry tools are sterilized once a day; (5) ground disinfection is performed after every sand removal; (6) the silkworm sand is not thrown upside down, and is promptly cleaned up and transported. Mulberry leaves can not be placed directly on the ground; (7) found that silkworm diseases should be strictly isolated; (8) change shoes into the room, wash their hands to Sang. After each period of silkworm rearing, the silkworm silkworm was completely disinfected, the mulberry silkworm feces was completely treated, and the used grasshopper was completely burned.
Sixth, Shangguanguan: do well cooked, batch, dilute. And we must do a good job of cooling and dehumidification work to strengthen ventilation. The temperature is based on 24°C, and the upper and lower limits do not exceed 1.5°C, and the humidity is 60%-75%.
Seventh, pick off: After most of the silkworms have disappeared, the pick is more appropriate when the carcass turns yellow. It is advisable to pick 6-7 days after the above clusters. The picking is too early, the carcass is still tender, it is easy to bleed, pollute the alfalfa layer, and affect the quality of the alfalfa. If the picking alfalfa is too late, it is easy to be parasitized by the fly pupae and the pupae can't be reeled. When you pick a pick, you must first pick it up first. After picking, picking and putting it gently, and picking the side to separate the good from the bad, don't pile up too thick. Take 2-3 grains thick to avoid heating and affect tannin quality.
Achieve a good seven-season summer silkworm production
In summer and autumn, high temperatures, high rainfall, high humidity, and frequent use of pesticides in crops have a number of adverse environmental factors for silkworm rearing. To obtain the high yield of summer and autumn silkworms, the following seven points must be closed:
