1. Adding soymilk When silkworms enter the fourth-year ingestion period or the third-day of fifth instar, the fresh soymilk is sprinkled on the mulberry leaves, which can reduce the use of mulberry by 10%, increase the body weight of silkworm by 5%, and increase the healthiness of silkworms. 3%, shortening the age of 2 days, silkworm cocoon production increased by more than 8%. The way to add soybean milk is to use 50 grams of soybean flour, add 1000 grams of warm boiled water at 40-50°C and soak for 30 minutes to make soybean milk and evenly sprinkle on 10 kg of fresh mulberry leaves at noon and 4 pm every day. Feed each one. In the feeding process, it must be avoided with chloramphenicol, sulfamethoxazole and other drugs to prevent drug failure or cause silkworm poisoning. 2. Adding the ecdysis hormone Silkworm ecdysone is a substance derived from plants or artificially synthesized like an insect hormone. It is fed once when the normal silkworm matures at 5%, or it is used for deficiency within 2 days before the maturity of the 5th instar silkworm. Leaf or diseased silkworms can adjust the silkworm ripening period to make the silkworm mature in the same way, shorten the 5th instar period by 8-12 hours, facilitate the concentration and management, and adjust the balance of leaves and silkworms, so that the silkworms can be mature one day earlier. The method is: Each silkworm with 40 mg of ecdysone, mixed with 2000 grams of cold water, fully stirred, and evenly sprayed on 15-20 kg of mulberry leaves, once to allow the children to eat. When dispensing, pay attention to the cleanliness of utensils and water, and use it now. If the temperature after feeding is lower than 21°C, try to warm it up. 3. Adding clear water to autumn silkworms to increase the moisture content of mulberry leaves by adding fresh water to meet the needs of silkworms, which can effectively improve the yield and quality of autumn silkworms. The effect is best for early autumn silkworms and mid-autumn silkworms. In the early autumn, the silkworms added fresh water. Compared with the fresh leaves, the total amount of eucalyptus increased by 13%, the amount of alfalfa layer increased by 16%, and the rate of alfalfa layer increased by 2.6%. Compared with the rearing of fresh leaves4, the total alfalfa increased by 2.3%, the alfalfa layer increased by 4.3%, and the alfalfa layer increased by 2.1%. The method of adding clear water is to spray the mulberry leaves with clean water (preferably well water) before and after each scab, with no dripping water as the degree, and then used to feed silkworms, generally feeding at high temperatures every noon. The humidity at night and in the rainy days is large, and it is not necessary to feed them. When the silkworms are hypnotic and satiety, they may not be fed. 4. Sprinkle the mulberry leaves with fruit preservatives and apply 50 times liquid preservative to the surface of the mulberry leaf evenly to form a thin layer of polymer membrane. Add the atmospheric repulsion coefficient to suppress the leaf surface moisture transpiration. The role of the mulberry leaves can maintain good freshness after 24 hours from the tree, so that the moisture content is still between 17%-21%. When this type of mulberry leaves is fed to 5th instar silkworm, the development of silkworm can be shortened by 2%-3%, the amount of mulberry is reduced by 1.4%-1.8%, the amount of residual mulberry is reduced by 3.5%-6.8%, and the rate of pods is increased by 4%-6. %, 50g dried wolfberry increase 5%-8%, leaf silk conversion rate increased by 5%, 50 kg of mulberry leaf output value increased by about 10%. The spraying method is: on the afternoon of the day before the leaves, in the mulberry garden directly 50 times the liquid preservative, spraying with sprayer on the positive and negative sides of the mulberry leaf, to spray evenly not drip down the water is appropriate. Pick up once at around 8 o'clock the next day, store it as usual and supply it for 24 hours. The sprayer used for spraying should be used exclusively. Sprayers that spray pesticides should not be used to prevent residual pesticides from contaminating the mulberry leaves and causing poisoning. 5. Spraying mulberry triacontanol with triacontanol is a novel plant growth regulator. Spraying the leaves of mulberry leaves with it not only improves the yield and quality of mulberry leaves, but also increases the constitution and quality of tannins after nibbling on such mulberry leaves. The method of spraying is to pour a suitable amount of fresh water into a clean and non-toxic sprayer, and then pour a certain amount of triacontanol at a concentration of 0.5 PPM. After thoroughly stirring, the mixture is sprayed evenly onto the mulberry tree. Both sides must be sprayed. Per mu of mulberry spray dilution 100-150 kg, once with triacontanol 50-75 ml, spraying time in the 7-9 days before the use of leaves, the general spray once, in May is appropriate.
Angle Grinder, angle grinder), also called grinding
machine or plate mill, is used for glass fiber reinforced plastic cutting and
grinding of a grinding tool. Angle grinder is a use of glass fiber reinforced
plastic portable electric tools for cutting and polishing, brush is mainly used
for cutting, grinding and grinding metal and stone, etc.
Angle grinder common model according to the use of attachment specification is
divided into 100 millimeters (4 inches), 125 mm (5 inches), 150 mm (6 inches),
180 mm (7 inches) and 230 mm (9 inches), Europe and the United States use of
small specifications more grinder is 115 mm. Angle classification compact mill
grinder and large Angle grinder, compact Angle grinder, super light, with or
without security configuration, meet the requirements of the diagonal mill; Big
Angle grinder: difficult power strong, suitable for grinding and cutting
operations. According to different grinding diameter and the applicable scope,
compact Angle of grinding machine is divided into: WSB10-115 - t,, WSG10-125 -
s, WSB14 WSG10-115-125 - t, WSG14-125, WSG14-125 - s, e, WSS14 WSG14-70-70,,
WSG14 MSFV649-1-150. According to different grinding diameter and the applicable
scope, compact Angle of grinding machine is divided into:, WSG25 WSG20-180-180,
WSB20-180, WSB25-180 - x,, WSB20 WSG20-230-230, WSG25-230, WSB25-30 x
Use a lot of, carpenter, bricklayer's welders are used to. Installed on
woodworking saw blade is a smart mobile woodworking saws, can deal with simple
woodworking, a lot of installation of the floor master with it. Installed on the
grinding wheel is a small portable grinding wheel cutter, cutting grinding small
metal parts, metal processing such as stainless steel window and light boxes are
made without it. Wouldn't it or make stone processing installation, can be
installed marble cutting wheel, and a series of films, crystal, flowing wool,
cutting, grinding, polishing all depends on it! To be sure, grinder design is
used for grinding, sawing, cutting function is not the intent of the designer.
Because of the high Angle grinder speed, the use of saw blade, cutting were not
forcibly pressure, can't cut more than 20 mm thick hard material, otherwise once
the card is dead, will cause the saw blade, cutting piece broken splash, bounce
off or machine is out of control, light damage to the goods, or hurt! Please
select above 40 teeth.
