How to carry out 5th instar silkworm mulberry slant breeding

The 5th instar silkworm mulberry slant education is a method of slashing the mulberry directly on the wall or bamboo larvae. The mulberry slanting system does not require the use of curtains and silkworms. It is based on 1 silkworm species, 5 instars 24,000 to 25,000 silkworms, and needs silkworm greenhouses or outdoor greenhouses (height 2.5 meters above) area 12 to 14 meters 2. 5 years old The maximum slope area is 16-18m2. In this method, mulberry is only fed once a day, and the entire 5th instar need only remove sand once.

Before the slope is set, the silkworm chamber is first thoroughly cleaned, and the ground and the wall are disinfected using a disinfectant net, a liquid of elimination and the like. Earthy ground should be laid with plastic woven cloth on the ground below the slope setting. There are four main forms of bevel setting:

1 Rely on the surrounding wall to set half slopes, stack the mulberry in the middle and make a walkway.

2 In the middle, take a slanted, adult-shaped slope, and stack the mulberry and operating aisles around it. When the herringbone slope is set, a wooden pile (or iron bracket) of about 1.5 meters is erected at each end, and a thicker bamboo is fixed at a height of 0.4 meters to serve as a fulcrum for the slope. The width of each row of herringbone slopes is set at a space of about 1.5 meters. The first to second days of the fifth instar are about 0.6 meters. Later, they extend day by day to reach about 1.5 meters in height and 1 to 2 meters in height. And the length of the branches vary, between the two rows of herringbone slopes must be left between 0.3 to 0.4 meters of sidewalks to facilitate the operation.

3 In the silkworm room with a depth of about 4 meters, a half-faced slope is set up around the wall, and the middle of the slope is adult-shaped.

4 Build a layer of silkworm silk, set up and down two slopes to increase the utilization of silkworms. In order to facilitate the operation of the upper slope, the height of the lower slope should be controlled below 1.4 meters.
