Raising seedlings in arch shed: before the seedlings are unearthed, it is also necessary to keep the soil moist, which is conducive to maintaining a high emergence rate. We have said that the summer and autumn seedlings cover the sunshade net, wait until the seedlings are all out, it is necessary to open the sunshade net in time to avoid the emergence of tall seedlings. In addition, because there is more rain in summer and autumn, we should also pay attention to avoid the seedbed being drenched and waterlogged by Rain Water, which is not conducive to seedling emergence. If there are continuous rainy days during the seedling period, we can properly apply paclobutrazol to control the seedlings and promote the growth of the seedlings. When raising seedlings in winter, the overall temperature is relatively low, so we can cover grass curtains or quilts on the arch shed to keep warm to ensure that seedlings emerge neatly.
Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of Zhuzhou conjoined greenhouse requires the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied.

The forming technology of automobile interior knitting is mainly divided into weft knitting and warp knitting. There are two kinds of warp knitting machines: single-bed warp knitting machine and double-needle-bed warp knitting machine, single-bed warp knitting machine produces single-layer warp-knitted fabric, double-needle-bed warp knitting machine produces double-layer warp knitted fabric, and after getting off the machine, the cashmere yarn connecting the upper and lower layers is cut off by the cutting machine, which is cut into two pieces of warp-knitted fabric and wound separately, and the automobile spacer fabric can also be produced. Warp knitted single needle bed fabric can be used as automobile seat accessories, ceilings, sunshade curtains, etc., while double needle bed fabrics can be used for seat ventilation and heating, instrument panel and door panel lining, etc.
