First, the small silkworm is still a plastic thin picture-in-picture advertisement.
1. method. From the beginning of the ant colony to the end of Sanling, the area of ​​silkworm rearing on plastic film for two times a day is 30%-40% higher than that on a three-day-a-day basis. The maximum silkworm area is reached in each order and the largest silkworm area in each district. The area is one order of 0.16 square meters, two orders of 0.4 square meters and three orders of 0.96 square meters. The size of cut leaves is the same as that of three rounds of cultivation. The amount of mulberry leaves is increased by 30% to 40% of the mulberry leaves compared to the first day. The mulberry leaves are required to be evenly distributed. Dry, only cover does not pad.
2. Give Sang time. The general choice is at 8 am and 8 pm. Look at the silkworm to give mulberry, and leave a small amount of mulberry leaf for the degree in the silkworm. Take a silkworm species as the standard. The order for the mulberry leaves is 1.5kg. Order 4kg, three orders 18kg, pay attention to advance expansion seat, timely stop mulberry, foraging. After 4-6 hours of feeding, supplement the mulberry again, give the mulberry a uniform thickness, prevent sandworm from drilling, and reduce the yield of the silkworm head.
In the middle and late autumn, silkworms are often housed in the same room. If the mid-autumn silkworms are slightly diseased, they will be transmitted to late autumn silkworms, and silkworm disease will be outbreaks in the later period and the production will be severely reduced. Therefore, special attention should be paid to strict disinfection and prevention of disease. In addition to good pre-silkworm disinfection, it is also necessary to disinfect silkworm body silkworms with lime or 1% anti-pointing powder before each feeding and before each foraging. Timely phasing out, investing in lime tanks, not feeding pests and leaves, contaminating leaves, preventing rodents, and preventing pesticide poisoning. If conditions permit, it may be better for the villagers' groups or natural villages to concentrate on breeding small silkworms, so that special rooms, special equipment, and special personnel can be raised and sterilized strictly to ensure no pathogenic bacteria infection at the young silkworm stage.
Third, large silkworms are mainly mulberry s
There are three types of rearing methods: silkworm rearing, silkworm rearing, and slanting silkworm rearing.
1. In silkworm rearing, no silkworm cocoon is used for culturing silkworms. Instead, they are woven into bamboo fabrics and are woven into 1.2-1.5m wide, and the appropriate length of the curtains is placed on the silkworm shelf. The silkworm shelf generally has five layers with a spacing of about 40 cm. Racks must be thick and the lashings must be firm. The use of silkworm silkworm rearing silkworms can save costs, speed up the speed of feeding silkworms, save labors for removing sand, improve sericulture efficiency, and reduce labor intensity.
2. Silkworm rearing is to raise silkworms on the ground, feeding leaves quickly, do not remove sand, save labor and improve the utilization of silkworm and other advantages.
3. The mulberry slanting surface requires approximately 20 square meters of sericulture for each silkworm species to be bred. Generally, the silkworm can accommodate 2-3 rows of silkworms. The erection method is as follows: stacking bricks about 35cm in both ends of the silkworm seat and in the middle, one bamboo basket on the bricks, and each row of silkworms is 1m wide. When the branches are placed obliquely, the width of the ground of the silkworm seat is controlled at about 50 cm, and thereafter, the width of the feeding leaves increases day by day to both sides. Between the two rows of silkworms, a sidewalk of about 35 cm is required for operation. One side of the wall can also take a single slope education. The slanting larvae are three-dimensional, silkworm excrement and disease, and weak silkworms all fall on the ground, which can reduce the chance of infection and facilitate silkworms' safety.
Third, breeding points
1. Generally after five orders and food 2-3 times, they are changed to mulberry s.
2. Mulberry cultivars should generally use uniform, finely-straight, and dense-spotted varieties. Small larvae should not be used to avoid stems and leaves.
3. Sang Jin is the same in all directions. Don't cross it. It is in the shape of Sichuan, and silkworms are flat. The sangha and the tips of the sangha are arranged at intervals and thickness.
4. Grasp the appropriate number of sang and give mulberry, generally three times a day and night, sang as far as possible arranged closely.
5. When the silkworm was raised in Taiwan, it took half an hour before the mulberry to remove the coarse branches that had been eaten, and reduce the burden on the silkworm shelf.
6. Sprinkle fresh lime powder every day or every other day to disinfect silkworm silkworms. If there is any stagnation, use a stale-prevention agent in a timely manner, and order 5,1,3,5,7 to add chloramphenicol and other agents to prevent bacterial diseases. 2. On the 4th and 6th day, body spray or adding fresh food to eliminate flies, adding chloramphenicol and eliminating silkworm flies before adding the ecdysone can effectively prevent dead cages and wormholes.
7. See 1-2 days before ripening, use leaves and leaves to make the silkworm seat flat and prevent it from lingering.
8. When the autumn silkworm cuts, such as raising two autumn silkworms, when the autumn silkworm picks the leaves, they are picked neatly and the height is as consistent as possible. After cutting, each branch should leave 2-3 leaves, and the end buds must have leaves. To continue photosynthesis, accumulate nutrient-filled shoots and winter buds, and allow them to fall off naturally, prevent winter buds from falling, leave 80-110cm, stay short, and stay strong for long.
9. Do warm up work. In the late autumn, the temperature of the silkworm is gradually lower during the breeding period, and it is necessary to raise the temperature from raising to raising the upper layer. In the last flood season, especially in the 3 days after the last squat, the indoor temperature should reach 24-25°C, which will result in faster pod formation and higher glutinous layer rate. At the same time, the temperature in the mash will be adjusted to reduce the rancidity.
10. Pay attention to leaf quality. Strengthen the mulberry garden fertilizer management, timely application of quick-acting fertilizer or foliar spray nitrogen, improve mulberry leaf yield and quality. The mulberry leaves are now fed to reduce the storage time and prevent the leaves from losing water. Aged mulberry leaves may be sprayed with water in appropriate amounts, but care should be taken to prevent the silkworms from getting wet.
